My current project requires that I'm able to specify the halftone parameters. The goal is not to rasterize the image myself, but to let the printer know how to print the embedded image. These raster images are often in PDF files that contain vector shapes and other text, but I'm confused as to how this is any different than viewing a normal PDF file with an embedded image. > There are no such controls in Illustrator's "Save as PDF" dialog. When a file is printed in Illustrator, we can choose "Save PDF" or "Save PDF as Postscript" from the native print dialog. The controls I referred to are on the output tab of the print dialog in illustrator. I've looked at the resulting postscript file and I discovered the postscript function "setscreen" which allows you to specify exactly the information that i need. ( screen angle, frequency, dot shape ). Do you know of any corresponding functionality in PDF? -- View this message in context: http://www.nabble.com/Halftones-tp15977367p16002524.html Sent from the iText - General mailing list archive at Nabble.com. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
