My objective is to save the final drawing and put it into a pdf file with other contents. After looking around, i realized that i can only save the canvas drawing as postscript file like this canvas.postscript(file="file_name.ps", colormode='color') So, i am wondering if there's any way (any python module?) that will allow me to insert the postscript files into pdf file as images. Is it possible? 回答1: As it is mentioned in this answer , a possible walkaround

I need to print the report from a Java desktop application to a dot-matrix printer (Epson LX-300 II). Report consists of text ang some graphics. Printer is connected via USB and I'm using CUPS to print. I'm printing using the Printable interface (pretty standard in Java). My problem: Text printing quality is very low on every printer resolution (60x60, 120x60, 120x72). It seems like there's no font hinting at all in some printer driver. Letters is looking very ugly. I can't use direct text-out to port (it looks great), 'cause I need also to print graphics on the same page. It seems that

The closest I could get to, is to specify explicitly x11 window as output device, specify width and height of the window via -g , and specify rasterization resolution via -r ; or, a command line like this: gs - sDevice = x11 - g500x500 - r150x150 - dFirstPage = 3 fontspec . pdf ... which results with something like: ... which is, in fact, all good - except, it starts at lower left corner; and there are no

I've been writing software to parse content from PDFs, specifically text broken into regions. For this I need font metrics such as glyph displacements, font-wide ascent, descent and glyph bounding box, etc. In short, the type of metrics that should be available in the FontDescriptor dictionary of a font definition in a PDF. Unfortunately a FontDescriptor doesn't have to be included for fonts whose base font is one of the "base 14" set of standard fonts. Where can I find or how can I generate font metrics for the base 14 fonts? On Linux (and probably on Mac OS X too) you can easily use the

I am in need of your support on the following issue since its pulling me for a while. We have a small c# utility, which print given PDF using GhostScript . This print as expected but fail to retain the page formatting’s. However, pages are printed as expected when I switch Adobe Acrobat in place of GhostScript . So I presume, I am making some obvious mistake on the GhostScript's command line arguments . Background Following is the core c# logic, which print a given PDF file with varying style across each pages. The given PDF file has pages; with inconsistent font style and colour some of the

I try to split a multipage PDF with Ghostscript, and I found the same solution on more sites and even on ghostscript.com , namely: gs -sDEVICE=pdfwrite -dSAFER -o outname.%d.pdf input.pdf But it seems not working for me, because it produces one file, with all pages, and with the name outname.1.pdf . When I add the start and end pages, then it is working fine, but I want it to work without knowing those parameters. In the gs-devel archive, I found a solution for this: http://ghostscript.com/pipermail/gs-devel/2009-April/008310.html -- but I feel like doing it without pdf_info . When I use a
