vector anti-aliasing: pdftoppm produces different result (darker, more black) than chromium PDF reader
i want to render PDF vector graphics to high quality raster graphics
for this job im using pdftoppm, but surprisingly, it creates a slightly different result than the chromium pdf renderer:
with pdftoppm, fine black lines are darker, so overall, the graphic looks darker

the screenshot is with chromium PDF reader at full zoom (500%) which gives the same size as a 720dpi resolution image
i have tried running pdftoppm with different options, and only -aaVector no
makes the result worse. so i guess im looking for a PDF rendering engine with more vector anti-aliasing, or with higher-precision anti-aliasing
