Tilman Hausherr commented on PDFBOX-870:
----------------------------------------

No I haven't committed it. The reason is that the current code has specifically 
the antialiasing set to OFF since start as an Apache project in 2008. I wonder 
why, maybe there was a good reason for it.

Re the fonts, this is my "mistake", because I saw Helvetica so I assigned it to 
Arial. The problem is I don't have a font for "Helvetica Condensed". I'd need 
something like "Arial Narrow" but with serifs.

The current plan
http://de.redtransporte.com/valencia/metro-valencia/plan.pdf
has no serifs.



> PDF-To-IMAGE output is not anti-aliased

> 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
