Several types of shading patterns are available: function-based, axial, radial, Gourad-shaded. cl-pdf doesn't have any support for this, but it shouldn't be very hard to add. The PDF specification is available from http://www.adobe.com/devnet/pdf/pdf_reference_archive.html You want section 4.6.3. </pre> Eric Marsden 2012-04-19T07:17:34 http://permalink.gmane.org/gmane.lisp.cl-pdf.devel/54 <pre>Hi, I would like to write a plotting function that draws image plots (plotting a matrix in 2d using colors). It would be useful to use gradients; in particular, paint a rectangle where the four corners each have a color and the each point in the rectangle has a color which is a convex combination of the corner colors. I think this is called a gradient in most libraries, but I could not figure out how to do it in cl-pdf (I have to admit that I didn't find gradients in the library, maybe I didn't look hard enough). Suggestions/examples would be welcome.

Read through and try out the #|'ed out test section at the bottom of the file. It helps to know a bit about the internal structure of a pdf document. There are also various command-line tools - google for "pdf merge", "pdf tools", "pdf parser", etc. pt _______________________________________________ cl-pdf-devel site list cl-pdf-devel-F1HGIaG5STRyXAeb93iumQ&lt; at &gt;public.gmane.org http://common-lisp.net/mailman/listinfo/cl-pdf-devel </pre> Paul Tarvydas 2012-02-12T16:35:31 http://permalink.gmane.org/gmane.lisp.cl-pdf.devel/51 <pre>Tamas Papp wrote on Sun, 12 Feb 2012 12:04:26 +0100 15:04: | Is it possible to embed another PDF file (ie render it contents at a | particular coordinate) in a document generated by CL-PDF? You can embed any file as a binary object and specify the corresponding MIME type for it. I am not sure about the way a typical PDF viewer will render such an embedded PDF file. In all probability, the viewer will open it in another window.

What does with-saved-state do? I've tried changing color inside this expression, and expecting it to go back to what it was before after the expression ends. Is this how it works? 2. I tried changing the fill and stroke colors for text on one line, and then a different color on the next line. But all text on the page ends up the last color I use. How can I have different color text? 3. What are the uses for in-text-mode and move-text ? I tried move-text while inside in-text-mode, and it seems to have no effect on the text location. move-to does not either. But vspace does. _______________________________________________ cl-pdf-devel site list cl-pdf-devel-F1HGIaG5STRyXAeb93iumQ&lt; at &gt;public.gmane.org http://common-lisp.net/mailman/listinfo/cl-pdf-devel </pre> jcm-B3LF187vQQA< at >public.gmane.org 2012-01-12T01:31:17 http://permalink.gmane.org/gmane.lisp.cl-pdf.devel/43 <pre>I'm trying to draw a title page, with some colored bars and images, and text as well.
