No, it isn't clear why you want to use PdfGraphics2D. If you are the so called 'John Smith' from news://comp.text.pdf you have an existing PDF document with images, I can't understand what this has to do with PdfGraphics2D. Maybe you aren't the 'John Smith' from news://com.text.pdf and in that case you got me confused by asking a very similar question. > I am basically using this g2d-Graphics2D-Object to paint Text and > Images on it.

Using JAI or another Java library/class. > I just wondered if this could be done directly by iText - Yes, but not like this: > I would like to specify a maximal resolution ( e.g. 300 dpi), If you want to specify a resolution, you need another tool. > and iText would do the down-scaling for me (I don't want too big pdfs > - size does matter). iText can change the images into a Jpeg with a certain quality if you create your Graphics2D object using this method: http://itextdocs.lowagie.com/docs/com/lowagie/text/pdf/PdfContentByte.html#createGraphics(float,%20float,%20boolean,%20float) The quality parameter is a float between 0f (0%) and 1f (100%). By converting all images to Jpegs and choosing a quality of for instance 0.1f you will see that the file size will be reduced enormously. Of course this is a completely different approach that doesn't answer your 'resolution' question. br, Bruno _______________________________________________ iText-questions mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/itext-questions
