Description Marcel Martin 2011-02-23 01:52:42 UTC
Created attachment 43697 [details]
a letter of very small height plus a red rectangle

The attached PDF contains two objects: a letter with a very small height and a rectangle. The letter is inside the rectangle, but it is rendered outside, to the right of the rectangle. Some PDFs created by the WebLogo program, available from http://weblogo.berkeley.edu/ , are affected by this.

I used a self-compiled poppler 0.16.2 and could see the rendering problem with the poppler_qt4viewer program in the qt4/demos directory. Evince does not have the rendering error, it simply does not show the letter (which is probably the correct behavior).

Seems freetype gets confused because we ask it to render a font with 0 pixels of height, have something that seems like a solution here, testing if it causes any regression
Comment 2 Albert Astals Cid 2011-02-25 12:35:36 UTC
Fixed in poppler 0.16.3

I am thoroughly impressed how quickly this has been fixed, thank you very much!
