I am making flowcharts with ConTeXt. Because the flowcharts have to be included in other documents, I would like to make graphic files (jpeg, png, ...). Also not bigger as needed to represent the flowchart. Can this be done. -- Cecil Westerhof

This works, but the problem is that I get an image the size of an A4. This is mostly whitespace. Is it not possible to only get the used part? -- Cecil Westerhof

Maybe wrap your flowcharts-code in \startTEXpage ... \stopTEXpage, ie something like this \starttext \startTEXpage Put your flowcharts-code here... \stopTEXpage \stoptext -- luigi

Works like a charm. Thanks. By the way instead of gs from ghostscript, you can also use convert from Image Magick. -- Cecil Westerhof

By the way instead of gs from ghostscript, you can also use convert from Image Magick. or GraphicsMagick, but as far as I know they still depend to ghostscript. An independent way is to convert the pdf with pdftoppm and then convert again the ppm to png/jpeg.

Import your PDF into Inkscape so you get SVG. From this format you can export to PNG at any size. On Sun, Nov 21, 2010 at 07:21, Cecil Westerhof wrote:
