Re: [ft] Unexpected Rasterization Differences - static vs. dynamic linking?

[Ben Wagner]

Note that there is no equivalent in the FreeType repository to what is installed on Ubuntu, there are a large number of patches that have been applied by Debian and Ubuntu. Some of these changes will change rendering and metrics. You can probably use the directions in third_party/freetype2/README.chromium and modify them for 14.04 instead of 12.04 to get the same source code.

Hi Werner and others,

I am experimenting with statically linking FreeType in Chromium instead of dynamically linking against the system version of FreeType. Doing this, I get unexpected rendering differences: 

Even if I statically link against the same numerical version of FreeType as it is on my Ubuntu 14.04 system, I get a different rasterization result than when I dynamically link against this system version library. The screenshot I am attaching shows the before - dynamically linked against system - vs. after, statically linked against the same version.

I am not sure I am interpreting the image correctly, but it seems that I am losing hinting somehow. 

Are there any modifications for hinting settings in Ubuntu's FreeType version? Or am I missing building/linkage of certain FreeType modules that affect this? Or are there different defaults and I should set them more explicitly?

Thanks for your help,

Dominik
