I've done a short look at the code and the pdf spec and have much questions about the coloring world My first questions to understand the coloring in fop a bit more are: 1. when i set a color (e.g. background-color at table) the ColorTypeProperty(String value); object is build for this color or not? Yes, but currently only with sRGB plus alpha channel (in FOP Trunk). 2. how goes this property into the pdf file? i saw the PDFColor class which already has the cmyk support!? Yes, there are some provisions for CMYK, but FOP internally transfers only RGB values. This will have to be generalized, possibily by using more of Java's color support classes, if the rgb-icc function is to be supported. 3. when i generate a pdf document and open it into the texteditor i can find things like /DeviceRGB when i use the rgb(100,10,50) colors, is it possible that my pdf has encrypted sections? If you don't do anything special, the page streams are compressed using the Flate filter. You can disable the filter in the userconfig file as shown in a post here on fop-users a few days ago. You will then see the right PDF commands to set the colors. Are you working on FOP Trunk or the old code?

I' m using the old at production version and for the cmyk task i'll switch to the trunk, because i think it is easier to add the cmyk to the trunk and the cmyk tiff image support of the trunk work - 20.5 not... But before adding some support for cmyk, i muss see if the other thinks we use at 20.5 will work on trunk.. with the same layout :-) Dirk Jeremias Maerki - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yes, this works! Thanks.
