I am using SVGs for all images. That was the only way that I could ensure print quality images with no dithering. For example the documents that I am generating contain a lot of pie charts, and these circles look great when using SVG but JPEG and PNG just didn't cut it.

I get similar situations depending on how I process. Using fop to generate a PDF (default) from a .fo file works for JPEG. Using fop to generate a PS file from a .fo file works too. Using ghostscript (gs) to rework the first PDF file to a PDF file makes the image chunky. Using ps2pdf to change the PS file to PDF makes the image chunky. Maybe not directly relevant to your situation, but I suggest to look if generating PS makes something printable with the proper resolution. -- #>!$!%(@^%#%*(&([EMAIL PROTECTED]@^$##*#@&(%)@**$!(&!^(#((#&%!)%*@)(&$($$%(@#)&*!^$ )[EMAIL PROTECTED]@) Tom Peters --------------------------------------------------------------------- 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]
