 Color Transform 1: R-=G, B-=G
 Color Transform 2: B-=(R+G)/2
 Color Transform 3: JPEG 2K lossless
 Color Transform 4: YCbCr (not supported by IrfanView)

 Created with Photoshop + lsjpeg plug-in, decodes correctly with IrfanView

 There is also "Color Transform 5: YCbCr 211", but I'm unable to create the
 file (error message).
