http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21420 Support for CMYK JPGs broken ------- Additional Comments From [EMAIL PROTECTED] 2003-07-08 21:45 ------- Attachment 7175 is my solution to the bug. It examines a region of the header FFE1 which appears to consistently identify JPGs generated by Adobe Photoshop with the text string "Adobe Photoshop" beginning 124 bytes past the index of "FFE1". I have tested this patch with five unique CMYK JPGs generated by Adobe Photoshop 7. While a better solution would be to check if the CMYK channel values are indeed inverted, I know of no way to perform such a test. The following URL, part of the IJG JPEG library, seems to confirm that there is no such test: http://courses.cs.deu.edu.tr/cse566/libjpeg.htm --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
