ipetopng converts a single page of an Ipe document as a PNG image. You have to specify the page and the resolution in pixels per inch.

ipetopng respects the following environment variables:

IPELATEXDIR

the directory where ipetopng runs Pdflatex.

IPEPDFLATEX

the name of the Pdflatex executable. If Pdflatex is on your path, the value pdflatex is sufficient.

IPEFONTMAP

the complete path of the font map, describing where Ipe can find the 14 standard PDF fonts.

TEXINPUTS

when running Pdflatex, Ipe prepends both the current directory (where Ipe was started) as the directory containing the current document to the TEXINPUTS environment variable.
