[ft] WG: Character Width Problem

Dear sirs,


we changed our windows-font-handling to freetype (version 2.1.4) to be platform-independent.


Our product runs on Windows-System as well as on Unix-Derivates.


Our problem is, that the character widths returned by Freetype differs immensely to those delivered by GetCharWidth32. In one of our test – cases every printed line differs from 0.5 to 1 cm. In this case the average character width returned by freetype is smaller than the average from GetCharWidth32.


What are the differences between those two functions? Does freetype use an other algorithm than the GDI-Functions? Can we do anything to get the same widths in both cases?


Best regards,



Martin Schöllerl
