i have some eps created with illustrator, when i convert images at 100 dpi antialias of some text doesn't work well, specially when font is Helvetica-Black
Created attachment 2447 [details] Eps file look at title when converting image at 100 dpi
Created attachment 2448 [details] eps.bz2 file: text render of Helvetica-Black is poor at 100dpi
What command line are you using?
The text is not present as text, i.e., not rendered with a text operator like "show". Instead, this text is rendered by using the "charpath" operator on a string, then setting that path as the clippath, then filling a box that includes the text area. For example, this is the way the title is rendered: /Helvetica-Black*1 findfont [11.7 0 0 -13 0 0 ]mfnt sfnt 84.1265 16.7446 mov (GLI STRANIERI IN ATENEO) false chp clp 84.5827 7.13765 mo 256.68 7.13765 li 256.68 16.9916 li 84.5827 16.9916 li 0 0 0 0 cmyk f ---- TextAlphaBits=4 anti-aliasing only works for text. Note that even setting GraphicsAlphaBits=4 won't have any effect on this method of rendering since the character outline is being used as a clip path, not being filled. A clip path is ALWAYS a "hard" outline -- never anti-aliased. The only way to acheive anti-aliasing with this kind of file is to use GS to render at 4 times higher resolution, then use something like 'convert' (an imagemagick tool) to resize the image. For example: gs -r400 -sDEVICE=png16m -o 867-400.png input.eps convert -resize "25%" 867-400.png 867-100.png I've attached the result and will close the bug.
