Loading images in WinCE

Hi,

I am developing an application which loads and shows big jpegs (like that of
3 to 4 MBs). Please anyone can give me some links or samples how to load and
show jpegs in win CE.

Thanks,

Arsalan.

or this:

but beware, the sample code provided contains nasty bugs that are left to
discover as an exercice to the reader...

You can use CVOImage (http://www.voscorp.com/ppc/dev) if all you're doing is
displaying the graphics. It will load them using the IMGDECMP.DLL that's
distributed with CE.

If you need to save the images, you might take a look at CXImage on the
CodeProject. I've only used it on desktop apps but it's very powerful.

One thing to keep in mind with either class is that there is no optimization
for 12 bit displays so you'd have to do that yourself (basically it's a
dithering technique) if you're targetting 4096 color devices.

Cheers,

the bottom-line is:

there is no API to load JPEG images.

there are some opensource license-free libraries available, but you need to
write some code to integrate them.

Hi,

I have checked my device. It does not have IMGDECMP.DLL. Its O2 xda pada
having ARM SA1110 processor and MS Pocket PC Version 3.0.12039 OS. Please
reply where I can find the required dll for my device.

Thanks,

Arsalan.

I'd be really shocked if it's not there since as I understand it Pocket IE
uses it. If you're looking for it using File Explorer you won't see it
because it's a DLL (which File Explorer doesn't display) you'll need to use
either Explorer on the PC or another file browser like Resco Explorer. Even
in Explorer it may not be displayed if you have "display system files"
turned off, although I'm not sure if it would hide PPC DLLs.
