Using CGImageCreate with an indexedColorSpace adds map to each pixel row

[cavalleydude]

I am using a color map lookup table in my indexed color space. When I use CGImageCreate to create the CGImage, then create a UIImage, I get an extra COLUMN of pixels in the first 32 bits (4 pixels) of every pixel row... which causes the image to shift right by 4 pixels. It looks like the color map is being written to the first 32 bits of every row... then the display system displays these extra pixels! Am I missing something or doing something wrong. I've researched the web and documentation and cannot configure it out...

The color map works perfectly, but I do not want to see the color map content as displayed pixels.

Here is the basic setup:

CGColorSpaceRef indexedColorSpace = CGColorSpaceCreateIndexed(rgbColorSpace, 255, lut);

cgImage = CGImageCreate( width,
height,
bitsPerComponent,
bitsPerPixel,
bytesPerRow,
indexedColorSpace,
bitmapInfo,
provider,
NULL,
NO,
kCGRenderingIntentDefault
);

UIImage *image = [[UIImage alloc] initWithCGImage:cgImage];

The resulting image is color correct, but a 4pixel line in the left side of the image which shifts the entire image 4 pixels to the right.

Any help would be appreciated.
