Ok, so that is a "no". Here's one that does have anti-aliasing. I set anti-aliasing to ON in PageDrawer.fillPath() and strokePath(). It is specifically set to OFF in the trunk, don't know why.

About the fonts: yes this is a known problem, see PDFBOX-1800 and PDFBOX-1701 and PDFBOX-1689. I complained about this myself. The first change I ever made locally (PDFBOX-1296, now obsolete) dealt with bad fonts.

> Hi
> I am a user of pdf-renderer from java.net, and I am looking into the pdf to image part of pdfbox.
> So far it seems that pdfbox can render more of the pdf that are problematic with pdf-renderer, but for those that work in both, the pdf-to-image output is prettier for pdf-renderer, as both the font and shapes/path/lines are anti-aliased.
> With PDFbox, the text is sometimes antialiased, but never the shapes/drawings.
> Is there a way to have shapes antialiased ?
> I am using the latest version from svn.
> Here are some examples in the difference of rendering
