Description Pedro Rivera 2011-03-28 18:25:12 UTC

When rendering pages at large zoom levels I get warning messages as follows:

  warning: font size too large (1152), not rendering glyph
  warning: ... repeated 12 times ...
  warning: font size too large (2880), not rendering glyph
  warning: ... repeated 4 times ...
  ...
  ...

In this case I was rendering at a zoom level of 48f and 64f. Is there some setting that can adjusted to cure this? I tried the same thing with SumatraPdf and the same problem exists at large zoom levels. 

Thanks,

Pedro

At the top of draw/glyphcache.c are a few constants.
MAXFONTSIZE is the one you want to adjust. The other two
just affect whether a glyph will be cached or not.

    Handle glyphs that are too large to render as pixmaps.
