--------------------------------------------
image.cpp - remove imgdecmp, replace with IImagingFactory:
// replace define line 24
#ifdef _WIN32_WCE
#include "foreign/imgdecmp/imgrendr.h"
#include <INITGUID.h>
#include <imaging.h>
#pragma comment( lib, "ole32.lib" )
#else
---------------------------------------------
image.cpp - add after DecompressImage(hBitmap)
// Create a surface from a IImage
static Surface* CreateSurface( IImage *img )
{
// Retrieve bitmap info
ImageInfo iInfo;
HRESULT hr = img->GetImageInfo(&iInfo);
if (FAILED(hr))
{
// FileLog("Failed getting image info...",hr);
return NULL;
}
// Create the surface
Surface* surface = new Surface( iInfo.Width, iInfo.Height );
// Blit the bitmap on the surface
HDC hDestDC = surface->GetDC( true );
RECT rc;
rc.left = 0;
rc.top = 0;
rc.right = iInfo.Width;
rc.bottom = iInfo.Height;
img->Draw(hDestDC,&rc,NULL);
surface->ReleaseDC( hDestDC );
//FileLog("Returning surface...",0);
return surface;
}
------------------------------------------------
Replace DecompressImage
static Surface* DecompressImage( const uint8_t* pBegin, const uint8_t* pEnd )
{
//FileLog("Decompressing Image",0);
// This will be filled with a handle to the image
HBITMAP hBitmap = 0;
// CComPtr should auto release.
CComPtr<IImagingFactory>pFactory;
HRESULT hr = pFactory.CoCreateInstance(CLSID_ImagingFactory);
if ( SUCCEEDED(hr) )
{
CComPtr<IImage>pImg;
hr = pFactory->CreateImageFromBuffer((const void *)pBegin, pEnd-pBegin, BufferDisposalFlagNone, &pImg);
if (FAILED(hr))
{
// FileLog("CreateImageFromBuffer failed",hr);
return 0;
}
return CreateSurface(pImg);
}
else
{
//FileLog("IImageFactory failed",hr);
}
return 0;

if you wanted to see if it works with older devices, post an exe and have us test it.

Good point, Jaimi. The SHLoadImage functions don't work with objects in a buffer. Also, not to confuse anyone, the resource images don't have to be GIF files, they just need to be in a resource folder called GIF. (Though maybe JPG, PNG, etc work too. I haven't tried those.)Jaimi wrote:Just to set it straight, the IImagingFactory code doesn't require any new stuff either -- it's been built into the operating system since 1999.
Not saying that people shouldn't use yours (or that mine is better), but for me, the reason that I choose IImagingFactory over SHLoadImageFile (besides the GIF issue), is because IImagingFactory supported loading images straight from a buffer, and was a drop-in replacement for DecompressImage. Since I wanted to support loading textures from "pak" files, I needed this functionality.
But other pages state that it does .png, .gif, .jpg, etc...MSDN wrote:Converts a .gif file in the resource file to a .bmp file. A resource .gif file should be coded in the resource file as follows: IDG_MYIMAGE_GIF GIF DISCARDABLE "MyImage.gif".
Syntax
HBITMAP SHLoadImageResource (
HINSTANCE hinst,
UINT uIdGif
);
