I'm working on exactly the same problem right now and this seems to be
working:
UInt32 pixels, npixels;
UInt16 myShort, *bmpBits;
BitmapType *myBitMap;
RGBColorType pixelRGB;
bmpBits = bmpGetBits (myBitMap);
npixels = 320L * 240;
for (pixel = 0; pixel < npixels; pixel++) {
myShort = (*bmpBits);
pixelRGB.r = RED(myShort); // macros to extract color fields from
UInt16
pixelRGB.g = GREEN(myShort);
pixelRGB.b = BLUE(myShort);
...
bmpBits++;
}
I say "seems to" because I'm having trouble getting the packing of RGB bits
in the 16-bit word right. Does anyone know exactly what it is? I'm using CW
9.3 on a Zire 71. I've been blissfully ignorant of ARM/68K endian issues so
far but I suspect it may be coming into play here.
