File Size : 175 kB File Modification Date/Time : 2010:02:12 22:50:40 File Type : JPEG MIME Type : image/jpeg JFIF Version : 1.1 Resolution Unit : inches X Resolution : 150 Y Resolution : 150 DCT Encode Version : 100 APP14 Flags 0 : Encoded with Blend=1 downsampling APP14 Flags 1 : (none) Color Transform : YCCK Image Width : 579 Image Height : 579 Encoding Process : Baseline DCT, Huffman coding Bits Per Sample : 8 Color Components : 4 Image Size : 579x579 The line of interest is: >Color Transform : YCCK So apparently its using a non-standard colour transform. Googling YCCK says: "YCCK model is specific for the JPEG image compression. It is a variant of the YCbCr model containing an additional K channel (black). The fact is that JPEG codec performs more effectively if the luminance and color information are decoupled. Therefore, a CMYK image should be converted to YCCK before JPEG compression." Hence this appears basically the same issue as bug 24854 (Non-standard colour models don't work well).
