Hi Marti, Two things:
1: I'm implementing YCbCr color profile support in ImageMagick and was testing this with two profiles: YCbCr 601 to Lab colorspace conversion profile (ycc601.icm) YCbCr 709 to Lab colorspace conversion profile (ycc709.icm) - found in (earlier?) distributions of LCMS. Using these on an YCbCr source image and converting to sRGB colors, the converted image looks terrible with almost all colors wrong. For example, converting black (0,0,0) gives the RGB color (15,91,0). This was with v1.10. I just tested if this was different with 1.11beta, but I get the same wrong RGB color. Converting to CMYK colors with a US Web Coated SWOP profile also gives wrong resulting colors. Is this a bug in 1.10/1.11beta? 2: I'm also working on adding a postscript CSA to EPS files generated with ImageMagick. EPS files with CSA's from LCMS look great. Colors are excellent! But I can't make it work with the small bit of postscript code in the end of the CSA: /Current exch /ColorSpace defineresource pop I have to change this to setcolorspace to make it work. Would it be possible to change the cmsGetPostScriptCSA function such that only the array is emmited? Applications wanting the remaining info (product name, description, etc.) may easily add this by using the API functions in LCMS. Further, the "%!" postscript magic in the beginning means the CSA must be encapsulated in %%BeginDocument %%EndDocument DSC comments, which isn't really necessary. An final argument for only emitting the CSA is that a well behaved postscript file checks for CIE-based colorspace support before trying to set one, which means colorspace setting is conditional. Thanks for any replies. /Lars ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
