Hi, I'm working with large images, and just created a conversion program to create some tiled jpeg compressed tiffs. I can create the files, and the tiffs seem to be valid enough to be read by viewers like irfanview.

Now I'm reading the same files into my own viewer, and having some trouble with the color model. There doesn't seem to be a ReadTileRGBA and I'm having trouble converting to my internal RGBRGBRGB... image.

What should look like:

What it does look like:

What's the best way to convert to RGBRGBRGB... (or BGRBGRBGR...) for all types of encodings of tiled tiffs?

Thanks,
-Jim
