To be a little more searious, there are times when all the good reasons to use the image editor beforehand, no matter how well thought out, are not of the essence. This is valid, for example, when one wants to publish the layout as screen print (where you usually want to keep some additional image outside the frame but in the PDF in order for the printer workshop to compensate for snapp-off distortion) on the one hand and to publish the same layout as a PDF for monitor use, where the additional "hidden" image areas will simply blow file size. Moreover, with the task at hand, the problem was that we had image files from scanned cardboard with historic fabric specimens glued to the board that the typical PDF user would view with an enlargement of around 400 to 800 % (!) where 96 dpi for monitor use is simply not enough, while other regions of the cardboard image would perfectly suffice with a resolution of around 150 dpi. Our first approach was to have the same image with different resolutions and overlay the low-res image in parts with the hi-res image areas (showing the specimens) within Scribus. However, since there was no simple approach to crop away the "hidden" image areas on PDF export from Scribus, we finally took a different approach to reduce PDF file size and worked with the hi-res images only, but reducing the contained information (or "high-frequency image areas") outside the image regions displaying the fabric specimens by applying gaussion blur and pixelizing to 4x4 pixel tiles (yes, in the image editor). This removed enough information from the hi-res images to allow for a halfway good JPEG compression within the Scribus gene- rated PDFs. Cheers anyways -- Dan. * _________________________________________________________________ http://redirect.gimas.net/?n=M1001xFotos2 Dein Santa Claus hat rote Augen? Jetzt X-Mas-Fotos bearbeiten!
