Folks,
I have created a small photo viewing application that I wanted to publish to the world. Key features are
- Native C code. No dependencies on .NET or any other library
- Tiny (just 25Kb)
- Full screen photos with gestures and hot-spots
- Slide-show mode
- Nice transitions (you can see them all in the slide show mode)
I have tested this on my GPS (CE 4.2) and PDA (Hermes) and it works quite well.
Gestures:
- Slide left to go to next photo in list (You can also use the wheel down for this)
- Slide right to go to previous photo list (You can also use the wheel up for this)
- Slide up to go to last photo in list
- Slide down to go to first photo in list
Hot Spots
- Top left to open a specific folder. Folder navigation is done by sliding up and down and select the <This Folder> to select
- Bottom left to open a specific photo. Again, you can slide up or down or go to a specific folder
- Bottom Right to start/stop slide show mode. Slideshow is 3 seconds. You can change the config file to specify different interval
- Top right to exit
- Right edge of screen to go to next photo in list
- Left edge of screen to go to previous photo list (You can also use the wheel up for this)
- Bottom edge of screen to go to last photo in list
- Top edge of screen to go to first photo in list
Configuration
CEPhotoViewer saves its configuration in CEPhotoViewer.cfg in the same folder as the exe. This file contains the last open folder and the slide show timeout
Startup
- On startup CEPhotoViewer looks for any JPG/BMP/GIF images in the program's folder. Else it prompts you to select a folder. Once selected the config file is created and subsequent runs, it will automatically pickup that folder
Bugs
- CEPhotoViewer uses native microsoft DLL to load a image. Depending on the speed of your CPU, this loading might be slow. Photos resized to the correct size (under 640x480) load pretty quickly. Large (2MP+) photos take a couple of seconds to load. Perhaps someday I will include native JPG loading codeDone
- CEPhotoViewer is built for ARM CPUs only. I can build for other CPUs but dont have a device handy
Looking forward to your comments. Im also working on finishing a MP3 player and a launcher (more appropriate for GPS devices)
Version history
- v0.67 (3/25/2008)
First public release- v0.68 (3/26/2008)
Integrated JPEG processing. Much faster in loading big images (although the size tripled from 20Kb to 60Kb)Added edge hot-spots to navigate in addition to slide gestures
Feature Request
What do you think of adding in touch Pan, Tilt, Zoom, & Rotate? Also, it would be cool if it auto rotated based on the original pictures orientation.
Thanks,
Curious G
i'll give this a shot when i get home

Forgot to mention, pictures are auto-rotated if they can fit better in the screen. Also auto-rotates if you change the display (like when I pull out the keyboard)
Nice but it wouldn't load my actual (2mp) photos. Sliding is a bit slow but very smooth. Wouldn't quit and at some point all corners stopped working.

Loading large images is time consuming, sorry, thats the way microsoft has implemented JPG processing. The corners are not 'not responding', the program is still trying to load the image.
Im trying to compile ijl jpg library that can loaded scaled images, that way I only decompress the size I want
3/26 - Version updated
Guess I'm in the minority who resizes images to fit in PDA screen. Due to popular demand, I have integrated the IJG jpeg library to considerably speed up loading of large images (largely due to internal image scaling)
Also added edge hotspots to navigate images, rather than slides which are bit cumbersome
my personal opinion(i havent seen program YET):
any viewer, that cannot show gif/animgif/png/tga/bmp files is pointless.
it doesn't matter how "touch"-ed it will be.
so - i am gonna update opinion after tests..

It does show gif and bmp. Adding png is trivial (libpng can be compiled easily in CE, both PNG and TIF take about 100Kb each). My intent is to what cover 80% of the people would want.
Just tried it on my Trinity and, while the transition speed is nothing to write home about, the software works. Not sure if i prefer this or S2V, but it has to be said this is a nice application.
Edit
Could do with more space at the top when navigating folders, the directory path disappers under the "This Folder" button.
Please could we have screenshots?

The main goal of writing this app was to have it working on all CE devices (including GPS that do not have the .NET framework installed).
Also, there are more transitions than just the slides that are visible when you are in slide-show mode
Amazing Program!!
I've just gotten myself a windows mobile phone. I looked everywhere for a simple photo viewer that could scroll through images by tapping on the left or right of the screen. I didnt understand why resco photoviewer or pqv or any of those other photo viewers didnt have this feature. It was so frustrating.
Also I wanted to browse folders starting at a pre-configured Picture folder. I didnt want the program to go scanning my whole PDA for pics including gifs and pngs for some other softwares.
Finally found this program and I'm really happy.
I wonder if you're still developing this program though? This thread doesnt seem to be active anymore. I hope you'll still continue developing this program.
If you're too busy, I'd be happy to help in some aspects of coding or improving the program. It really is that amazing to me.
Hope this program is still alive.

Glad to hear that this application is working well for you.
I have not stopped development on this, added additional features like PNG, GIF decoding and automatic rotation.
This being a PPC forum, there is not much need for this app since there are multiple options (including built-in applications). I had made this app and many others primarily for GPS and other low end devices without the standard libraries.
I will update this thread with the latest version and also add other applications I have built (including native MP3/OGG player, simple shell, GPS dashboard etc), all totally skinnable and configurable
The program has been amazing. Loads huge pictures with no problem. It's definitely faster than Vito's EyePhoto.
But Coolsva, I have a question. Now call me crazy, but I want to be able to set it up so that when I click a jpg file in file explorer or total commander, it will open up in your photoviewer instead of the windows mobile default viewer (coz it sucks). What're the parameters to do so? I tried the normal parameter "%1" but it doesn't seem to work.
I'm glad you're still working on this program.
Cool program , but zoom would be nice feature

Looks interesting, please do it !
Just now landed at this thread after spending a while checking out google results for "windows mobile picture viewer". Coolsva's prog sounds very worth trying, but I'm wondering if 0.68 is still the latest release?

hi
i have installed tomtom 7 on my diamond and i have one problem.
Probably because of diamond's screen resolution(640x480) during navigation poi icon are too small....there is any way for fix it?can I just resize poi icon?
I have got the same problem, during driving you can't see the small icon properly, but secondly I am using the voices as well, so rather than just the beeping sound my camera database tells me what speed camera is ahead, so this solves the issue even better.
According to your advice I did try to edit and even created a new image of 32x32, 64x64, & 128x128, but none of that work, it just start to show a blank RED icon rather than "30" written on it, so I revert it back.

yes im using voices as well,but with ipod conected to the car's hifi its hard to hear anything else
I guess this problem should appear on every diamond,but around i havnt found any discussion about it.......
So,its a common bug or just for few lucky diamonder??
I have the same problem, the icons is too little

Icons gone !
I have no icons on a Western Europe map V725.1905
But i do have them on an Benelux Map V725.1883.
I don't know whats going on, i use TT7 V7.451 (9033).
Also my WE map loads and is very slow and Benelux is very quick.
Check it out, maybe i'm the only one.
Sorry guys one more clarification, are you using QVGA Tomtom version?
As I was using the QVGA version of "7.40.9028", but now I am using VGA "7.451.9033".
VGA has got normal resolution as in the QVGA everything was TINY.
Basically it is just one EXE file to overwrite the existing QVGA exe in the device, I don't know if the moderator will allow this, otherwise I could upload that.
Regards
Sid
I'm using the VGA Black 7.451.9033 on HTC Diamond, but the radar icons, poi, ecc. are too small and remain too small even by increasing the zoom

Like me!!!
My solution: I edit TomTom.exe to run it at low resolution mode. You'll see all menus fine... and the map and navigation screen at normal size (normal as QVGA equipment).
I spoke with TomTom's service and nobody has solution, while I can use TT7 at car and easily I can see the radar warnings.
From Xda developer tread...i don't remember where......:
I must say when I first got my Diamond it was TomTom that I was looking forward to putting on there for the real VGA 'experience' and at first glance I was very impressed... but then I started using it for navigation and, not least given I use it in 2D mode, soon found that everything was a tad too small! I wasn't so fussed about the POIs but it was the map scale overall - at arms length I could hardly see the map detail and really didn't need to see for 10 miles around - it wouldn't be so bad if it didn't zoom out so much.
So, here's how I sort of fixed it.... a kind of workaround which disables TomTom's awareness of it being VGA. The upshot of this is that everything becomes a reasonable scale however the drawback is that it's a waste of VGA and at first glance you might think 'oh my God that's awful - so blocky!' but I soon found that when actually using it in my car I really don't now notice. The blockiness is down to running at a non-native resolution - like all fixed-pixel screens you end up with unclean lines.
Grab yourself a copy of the freeware resource PC tool Resource Hacker, make a copy of the TomTom Navigator.exe file on the PPC, and open it up with the tool.
Now find the resource CEUX\HI_RES_AWARE\2057, right-click it and delete it. It will likely take the whole branch with it if it is the only entry in there. Now save the resulting file (I got an error at this point - dunno if it's Vista or what but it still seemed to work) and copy the file back to the PPC (note it makes a backup so make sure you get the right one!) - you might want to call it something different so you can then have a choice of VGA or non-VGA TomTom's to run.
And that's it... I'm sure when you first see it in action you'll think it's horrible... but in use I think it is fine and indeed for me makes it at least usable once more.
Lucausee i have use your solution, in effect solve the problem, tnx.
Excelent fix, well done and thanks.

There are numerous video's out there showing things the HD can do but MY version certainly can NOT. And despite how cool these features are, surprisingly hardly Anybody talks about them, I find almost no information anywhere on this forum or on Google.
Check out this video, for example. A nice demonstration of LOTS of features that to my knowledge do not exist on the HD:
http://www.theunwired.net/?item=videoview-hands-on-with-the-htc-touch-hd-windows-mobile-smartphone
- First of all, the thing that caught my eye the most, is THE LACK OF THE ZOOM TRANSITION EFFECT BETWEEN PAGES THAT WAS IN ALL THE PREVIEW VIDEO'S.
- Then, there's the the IN CALL RECORDER application. Where the heck is it?!
- And even more important (yes I like graphics), the OPERA TAB SWITCHING, with its Cover Flow-ish way of showing all the open tabs as separate windows in semi-3D... See the attached screenshots. Also note how the buttons in the browser (at the bottom) are aligned differently. Can I get this Opera version somewhere?
The list goes on.
Why are these things not in the HD, or are they in yours and just not in mine?? Is it some firmware update I don't know about?
Please, enlighten me.
why they have removed the tabbing feature is beyond me.
I wonder if these are features that can be enabled?
My girlfriend has the Nokia N96 and her version of Opera even supports this. No, it does not look as fancy with the reflections and all, but the same tab windowing is there.
Also they said this version would include Flash Lite 3.1 well I can't even watch a video on the YouTube site. It does show more than without plugin (the movie overviews) but no playback.
And the zoom effect... As stated in a different thread it may be a performance issue, I can imagine it can cause freezes and instability, just like with the Manila tab-to-tab scrolling where you would see one screen flip away and the other one in, like on the first Diamond firmware versions. They just removed that transition because it lagged a lot.
Too bad.. The zoom effect looked really nice, albeit a bit iPhonish...
The Opera tab navigation is a mystery to me though. It's completely unrelated to other software and so it would not cause instability, it's just a missing feature in Opera.
And where is my in call recorder?? Such a tool seems very handy in a lot of situations, such as when contacting help desks, customers etc.
hi guys,
i'm also very interested to enable or find the OPERA TAB SWITCHING like on symbian nokia or iphone, it is really great;
and another thing, i want to have more than 3 pages open at the same time in opera, and it is set to 3 maximum...do you know where to set more pages allowed.?
thanks
While I agree it sucks that some features were pulled, it happens. One feature I do like (a lot) that was left in was the zoom feature in Opera (not the tap on page thing).
Click on the magnifying glass (bottom left) when in full screen mode, zoom away.
I'm just fed up with this wallpaper issue in Manila.
When I got my Touch HD I figured someone will figure out why exactly is the 800x400 screen reducing wallpaper image quality to some low-res sh*t.
But, it's been months now, and no one seems to be working on this, so what the heck - I've decided to post it here, in hope that someone will actually try to do something about it.
What really disappointed me was the fact that even the latest Manila 3 from Topaz and Rhodium still has the exact same issue. So, it seems obvious to me that guys from HTC have no intention of fixing this. Why? I don't know.
But I do know it's frustrating to have all those fancy graphics, all that big, high-res screen, and then be forced to stare at THAT all day long.
Since I've seen so many great things being done to improve Manila, such huge changes to the whole system, I reckon there must be a way to improve this as well.
p.s. If no one cares, just take this as a bunch of rambling from a visual kind of guy
Oh, and just to share my info so far:
- the wallpaper picture format has no impact (I have tried them all - jpg, png, gif, bmp, 8 bit, 16 bit, 32 bit etc.)
- wallpaper picture size has no impact (it will look just as bad if you use 640x480, 800x400 or 8000x4800 pixel)
- if you put 800x400 wallpaper, it will not be stretched in any way - it will fill up the screen exactly 100% full, so people reporting 640x440 photos having better quality when used as wallpapers were having a placebo effect.
- the default Manila wallpaper is crisp sharp - no trace of any quality degradation.
- all default Manila wallpapers are very simple looking, with small number of colors, and very short range of colors (mostly it's just shades of gray and black)
- TF3D obviously applies some kind of compression algorithm to any applied photo, increasing brightness and applying very, very, very agressive image compression.
I believe it is this compression that is the cause of the image degradation. If someone could find the registry key to turn it off, I assume the problem would be solved. I also have a feeling that this compression was pushed up so high in order to speed up TF3d.
I am attaching an enlarge example of this compression. Original wallpaper vs. how it looks on TF3D.
I have no idea if I should move this somewhere else..
so Rozenthal, is this meant to be a development thread?
Well, more of a "hacking" if you want. If an application would arise from this, it would sure be great, but tracking down the problem itself and finding a manual solution would be also very much appreciated.
I posted this into this forum because I figure here's where most of the people dealing with Manila graphics are hanging out.
Bla, fixing up my CFC patch for Manila to be able to load PNGs would possibly solve this. However I seem to recall something about the background always being shrunk to 512x512 max with the vertexes then stretched to fill the screen. Not completely sure on that, though.
And yes, QTC compression (used for Manila) is definitely lossy. It can be pretty decent though, depending on the editor you use.

Chainfire, you must be reading my mind! I was just now reading that thread of yours where you used CFC to resize images for QVG and was going to write to you
I believe that information you provided in that thread MUST be somehow linked to this problem. I have only skimmed through your thread, but from what I understand there is in fact a compression algorithm involved in all Manila graphic files?
About the 512x512 - I can almost certainly say that this is not the case in Touch HD. The images you use for wallpaper do not get scaled in any way if they're in 800x400 resolution. They stay the same (this was the first thing I tested). However, they do seem to go through some sort of compression that causes any kind of graphic to look bad.
So, you're saying there's a way to manually compress with better results? But what then? How do we apply the custom-compressed image? I'm guessing it would be necessary to first find out which file is the default Manilla wallpaper, and then replace the new one with that? Would that work? Can this somehow be automatized?
I know it's a lot of questions, and it's late, but any help would be appreciated, especially because I feel that this might be the closest we got to solving this damn problem.
Cheers!
Have you tried interlacing your .pngs? I realized that interlacing my images for manilla 2D themes helped. I was also under the impression that HTC has some special compression going on with their images, but while saving my images in photoshop, I save them in .png and select interlace option in the end. Try it.
Here's what's up:
1. When you save images for your pocket PC, they DO have to be in a loss less format, such as .png... This goes for Homescreen backgrounds as well, so when you save a picture off your phone camera, it'll be pixelation by default because they're usually in .jpeg format.
2. When you save images in Photoshop, in a format like .png. Save them as Interlaced images, or they'll come out crappy on the device.
3. If you are using the color overlay feature in Photoshop to, say, change the color of the image, There will be pixelation if there are any gradients in the picture. Most of the images in the Manilla 2D theme files have gradients, so almost all of them result in pixelation. What you have to do for those is: Zoom in and use the Blur tool (Smart Blur filter on larger images.) to smooth out the pixelation!
Hope this works for other people, and if someone can contribute anything else, it would also be appreciated.
The screen is 800x480 isn't it?
yes it is 800*480
makes me feel bad that it looks like that on such a beautiful device.
its obviously unacceptable that HTC playes like that.
i dont understand whats their big problem to give us some drivers that would solve this annoying issue
Here, try this file out. Make a backup copy of yours unless its cooked in rom, that way you can delete this if necessary. It makes a difference for me. In this section of script, I changed the values to 200, 200 and it was reeeeeally crappy. I did that when I was checking effect. Originally it was 512, 512. In this one, I made it 800, 800.
I think it also makes bg's better if you make them square(in my case 640x640), especially if your using the new landscape manila. I know on touch pro, the rotation works better with bg's that don't have to be stretched.

Re Wallpaper Resolution
I'm sorry but the Wallpaper you have as an original is of such poor quality that no phones resolution could correct it. I have a Touch HD myself and have made many Themes for all different phone resolutions and now for my new phone as well and have never had trouble getting what I expected and I use all of the graphic formats ie: .png .jpg etc.
For WVGA the Backgrounds actually need to be 480 x 696 for portrait and 800 x 366 for Landscape, what has not been taken into account is the size of the top and bottom bars which are both 52 pixcels adding up to 104 pixcels this needs to be subtracted from the overall size.

Of course I tried. I tried interlacing both PNG and GIF's, I also tried different color depths, and all supported picture formats. It had no impact.
The thing is images don't look crappy on the device - when you view them in Album application, they look excellent. Actually, they look better then on my 30" Apple cinema screen, because HD has such huge pixel density.
However, when you apply these images to act as wallpapers on Home screen, they drop in quality and sharpness so much that it degrades the whole device appearance. And this is very annoying

The image I attached is 600% blown up version, that's not full size wallpaper.
And it doesn't matter what kind of quality of image I use - the images always appear much less sharp and with reduced quality when applied to home screen wallpaper.
Also, I don't think you're right about 480x696. That is the "visible" area of the screen, but homescreen wallpaper will always be used in 100% if the width is 480 or height 800. It might get cropped tough, can't say that for sure.
But, for example lets say you want to use image that is 800x800 in original resolution. When you set it as wallpaper, it will not be resized to fit 696 height, but rather it will be cropped on the sides, and the top and bottom bars will cover the top areas of the image. But there will be no scaling involved. This can be easily tested simply by overlaying the original image over the captured image of the device.

Hey, thanks! I have tested this, using 640x640 images, as well as 800x480, and 800x800. I can't say if it's a placebo effect, but the image does look slightly better.
Could I ask you to make a few versions of this file with parameters that can be substracted by 512? Because if I remember correctly, Manila likes those 512 numbers. So, if you would be so kind to make 1024x1024, 1536x1536, and 2048x2048.
I would be glad to test them to see if there are any further improvements over this issue.
Ok, I tested everything again with a different wallpaper, so there's no more question whether the source file is good quality.
I think this image is suitable, because it has a lot of small details, but also large areas with soft transitions, so we can see the effect of compression on both the detail and the textures.
I also tested 696 file, and as I said earlier - it has absolutely no positive effect to image quality.
I have also noticed that in fact even the HTC Album applies some sort of image compression, but it's much much less visible! You can notice the effect of this on the dark area transitions. However, it's barely noticable when viewed on the device.
Perhaps if someone who knows where the HTC Album Manila files are, maybe it would be possible to compare them with the files that control compression in Home screen? Perhaps it would be enough just to copy the settings for HTC Album? Just an idea...
I'm attaching the files, they speak for themselves.

I don't think it's that simple anymore. We probably need to combine 2 things: the edited Manila file to support graphics up to 800 pixels, a way to easily compress a photo with ATC compression and then make Manila use it.
OK, I think I finally figured out some stuff. First of all, we knew from before that wallpaper image for landscape was made out of 2 bitmaps.
However, it seems that this is the same case with the portrait wallpaper as well.
Digging through Manila graphic files I've found that indeed the maximum image size is 512x512pixels. So, in order to get the 480x696 pixel needed to cover the whole visible screen area, guys from HTC simply used 2 images, each with 512x512 resolution, but first actually covering 480x512 area, and the second 480x184.
Together, as you can see, they make 480x696.
But, what happens when you load 800x400 pixel image?
Most likely that the image first gets cropped to 480x696 dimensions, and after that top part (480x512) is put into one file, and the bottom part (480x184) is put into a separate file. They both get compressed with that ugly algorithm and that's why we end up with crappy looking wallpaper photos.
Files involved are:

PORTRAIT:

Now, it's clear that Manila indeed does support full resolution, but because the wallpaper is being split into 2 parts and compressed, we have poor image quality. What brings us back to my first idea - is there a way to disable this compression, or increase the quality of the compressed photo by somehow forcing the compression algorithm to produce higher quality images?
Another way would be to use a Manila editor, cut the images into 2 manually, update old Manila default wallpaper files and always use the default background.
This is of course major pain in the a$$ to do each time you want to simply change a wallpaper.
Oh and by the way, for the record, I just manually updated these Manila graphic files, overwrote the old ones and I'm looking at my full-resolution wallpaper right now.
So, this obviously can be done. The question is can it be automatized?
this is a tricky subject.. well i've always edited the 4 manila files to create my wallpapers on my Raphael.. well i also tried background for all tab but that's kinda buggy in the prosess of when i change from portrait to landscape.. well it's like the background for all tab app kinda takes the image i want as background and overlap the 4 manila files that has to be edited manually to make a great background,... well anyway i'm stuck with the same thoughts as this thread states... it's not so fun to always have to edit those manila files to create a good background and so forth...
Hi guys
This is my first post in XDA, but I've been browsing the site for a while and have found a whole pile of useful tweaks & apps.
However, I've got a Touch Pro 2 (unbranded) and was wondering if there's a way to configure the Zoom Slider when viewing docs, excel files and emails etc to go in more than one zoom level. I'm assuming of course that my device is working as it should, which it appears to, as in Opera it will do a progressive zoom as you slide, but this is not the case in docs etc?
Does anyone know of a reg hack or similar for this?
Any help is much appreciated

haven't heard of anything but this is an app says that it changes the use of the zoom bar haven't tried it myself but sounds promising may find it helpful.
Yeah, I had seen that one from doing some searching, but from what I saw on it, it justs adds more functions to the slider as opposed to tweaking existing functions.
I may give it a try anyway.
Thanks for your reply
