Creating graphic file instead of PDF

Creating graphic file instead of PDF

[Cecil Westerhof]

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.

Just convert the pdf in jpeg with (for example) ghostscript.

Import your PDF into Inkscape so you get SVG. From this format you can
export to PNG at any size.

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?

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

Works like a charm. Thanks.

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.
