It consists of lines, circles and text for about 12000 individuals. I know that the pdf format can handle it, as this ancestor tree has been done manually with Coral Draw. The pdf isn't that big in size, but it contains a large amount of objects in one single page.<BR><BR><BR>When I get about halfways I get the CAIRO_STATUS_NO_MEMORY error.<BR><BR>I have tried cairo_pdf_surface_create_for_stream(), hoping to be more in control of how much is in memory, but I get the out of memory error from cairo before the callback is called.<BR>The only way I've found so far to flush the buffer and avoid running out of memory is by calling cairo_show_page(). That will emit the data in the stream, but then I get a pdf with more than one page! :-(<BR><BR>Is there anyway of flushing the data from memory to the file without switching to a new page?<BR>Or any other suggestions?<BR><BR><BR>My enviroment is Win Vista, Visual C++, using Cairo binaries v1.8.10 from GTK+.<BR><BR><BR>Thanks,<BR><BR>Keith<BR>--<BR>cairo mailing list<BR><A href="mailto:cairo@cairographics.org" ymailto="mailto:cairo@cairographics.org">cairo@cairographics.org</A><BR><A href="http://lists.cairographics.org/mailman/listinfo/cairo" target=_blank>http://lists.cairographics.org/mailman/listinfo/cairo</A><BR></DIV></DIV></div><br></body></html>
