I have been using
CGContextRef context;
context = CGBitmapContextCreate (m_bitmap.m_array.m_array,
m_bitmap.m_array.m_pixelsx, m_bitmap.m_array.m_pixelsy, 8,
m_bitmap.m_array.m_pixelsx * 4, colorSpace,kCGImageAlphaNoneSkipFirst|
kCGBitmapByteOrder32Host);
CGImageRelease(m_BitmapImage);
CGContextRelease(context);
CGImageRetain(m_BitmapImage);
Then
CGContextDrawImage(cellViewContext, r, m_BitmapImage);
and all is well.
Now I use an NSBitMapImageRep and my colors are off
m_ptrs[0] = (unsigned char*)m_bitmap.m_array;
m_NSBitmapImageRep = [[NSBitmapImageRep alloc]
initWithBitmapDataPlanes:m_ptrs
pixelsWide:m_bitmap.m_pixelsx
pixelsHigh:m_bitmap.m_pixelsy
bitsPerSample:8
samplesPerPixel:3
hasAlpha:NO
isPlanar:NO
colorSpaceName:NSCalibratedRGBColorSpace
bitmapFormat:NSAlphaNonpremultipliedBitmapFormat|
kCGBitmapByteOrder32Host
bytesPerRow:(4*m_bitmap.m_pixelsx)
bitsPerPixel:32];
I am confused by this as m_bitmap.m_array is created identically in
both examples
