<pre>Does this patch to pdftops have any chance of being accepted?
The anti-aliasing code paths are well tested, so enabling anti-aliasing should
be safe: GlobalParams.cc initializes antialias to gTrue, so pdftoppm has
anti-aliasing enabled by default, and pdftocairo enables anti-aliasing for
bitmapped output.
The generated postscript should remain the same unless pdftops has to fall back
to rasterizing the image, so normal ps output will be unaffected:
PSOutputDev.cc uses the anti-alias flag only in checkPageSlice() when it needs
to create a SplashOutputDev.
Why does GlobalParams.cc initialize antialiasPrinting to gFalse? Is it for
performance or memory issues or does enabling anti-aliasing have other side
effects that produce bad postscript output?
In my case, I am using pdftops to make an eps that is one of many images
embedded on a postscript page, and then the page is both printed and converted
to PDF for viewing over the internet. When pdftops rasterizes an eps,
anti-aliasing makes text in that eps look better in the printed version of the
complete document and much better when viewing the PDF version of the complete
document.</pre>
