Decode failure.

[MartinDavidWaller]

Hi,

I'm having trouble getting the library to decode the attached image - or indeed any image.

My code is quite simple:

// Load the image

GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR           gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);
HBITMAP mBkgImg = mLoadImage(L"i:\\RedTitan\\Test002.png");
BITMAP bm2 = { 0 };
GetObject(mBkgImg, sizeof(bm2), &bm2);
LONG cx2 = bm2.bmWidth;
LONG cy2 = bm2.bmHeight;

GdiplusShutdown(gdiplusToken);

DmtxImage* img = dmtxImageCreate((unsigned char *)bm2.bmBits, bm2.bmWidth, bm2.bmHeight, DmtxPack32bppBGRX);

DmtxDecode* dec = dmtxDecodeCreate(img, 1);
dmtxDecodeSetProp(dec, DmtxPropImageFlip, DmtxFlipNone);

DmtxRegion* reg = dmtxRegionFindNext(dec, NULL);
if (reg != NULL) {

	DmtxMessage* msg = dmtxDecodeMatrixRegion(dec, reg, DmtxUndefined);

All seem to be going well, all the objects are returned as expected but msg is always returned as NULL.

I wonder if I am missing an important step but looking at the samples that I have found all seems fine!

Any suggestions would be much appreciated.
