I use cygwin to convert a pdf file to png. It seems some installation package is missing or there is a problem somewhere
D:\>convert -d 300 foo.pdf bar.png
convert: unrecognized option `-d' @ error/convert.c/ConvertImageCommand/1382.
I went digging around, and I discovered this Stack Overflow post, which was a bit similar to yours. It, in turn, linked to this blog post, which describes using convert
on the command line as this:
convert -density 300 -depth 4 lang.font-name.exp0.pdf lang.font-name.exp0.tif
In other words, -d
may not be a valid option, partly because there are multiple options which begin with the letter d
. Try using the following:
convert -density 300 foo.pdf bar.png
You may have to also specify a depth
parameter.
