In QGIS project, we are using Sphinx to create our documentation as HTML and PDF. We are having a bit of a problem with figures as they show a bit blurry in PDF. I found out that the reason is because
texi2pdf default DPI is 72.
I would like to set it to something like 135dpi.
I have read somewhere that I should use
\pdfimageresolution for this; I tried to use it as:
latex_preamble = r"""\pdfimageresolution135"""
in the sphinx
conf.py file, but with no results.
Can anyone explain me if this is the right direction, or what is being done wrong?
