http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21420 Support for CMYK JPGs broken Summary: Support for CMYK JPGs broken Product: Fop Version: 0.20.5 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: Other Component: images AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] It is well known that Adobe Photoshop for unknown reasons inverts the channel values in a CMYK JPG file, such that 0 is black rather white. The author of org.apache.fop.image.JpegImage knew this and wrote support for it. However, the condition used to determine if the JPG was generated by Photoshop is incorrect. JpegImage checks if the Adobe APPE marker is present in the file. If it is, it assumes that Photoshop created the file. Actually, many other applications use the Adobe APPE marker standard when creating JPG files but do *not* invert the CMYK channel values. As a result, these JPG files are being displayed with inverted colors. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
