|Issue 2687||generate test typeface for gm and other tests|
|Starred by 3 users||Project Member Reported by firstname.lastname@example.org, Jun 23 2014||Back to list|
A gm today can specify that it is indifferent to the font used by text. sk_tool_utils::set_portable_typeface(&paint); Ideally, all Skia test apps would trigger this behavior for all tests that create a paint, without setting its typeface. Reed suggests that this could be achieved by installing a custom FontMgr after Graphics::Init() that returns the typeface created by SkTestScalarContext as the default typeface.

Ben, if you're not a good owner for this, feel free to set it back to blank. I have iOS gm working now, so it would be very helpful to have a way to compare gms between a Mac and an iOS device. Today, the same GMs draw very differently because the pair of platforms use different fonts and font metrics. If this is painful to fix, I'd like to implement my earlier strategy of hand-editing each GM to use a common font from the resource directory.

The following revision refers to this bug: https://skia.googlesource.com/skia.git/+/992c7b03ef7914a18bfd78e965b0b4c99a5f5672 commit 992c7b03ef7914a18bfd78e965b0b4c99a5f5672 Author: Cary Clark <email@example.com> Date: Thu Jul 31 08:58:44 2014 -0400 Add standard fonts to all GMs. Allow GM results to be compared across machines and platforms by standardizing the fonts used by all tests. This adds runtime flags to DM to use either the system font context (the default), the fonts in the resources directory ( --resourceFonts ) or a set of canonical paths generated from the fonts ( --portableFonts ). This CL should leave the current DM results unchanged by default. If the portable font data or resource font is missing when DM is run, it falls back to using the system font context. The create_test_font tool generates the paths and metrics read by DM with the --portableFonts flag set, and generates the font substitution tables read by DM with the --resourceFonts flag set. If DM is run in SkDebug mode with the --reportUsedChars flag set, it generates the corresponding data compiled into the create_test_font tool. All GM tests set their typeface information by calling either sk_tool_utils::set_portable_typeface or sk_tool_utils::portable_typeface . (The former takes the paint, the latter returns a SkTypeface.) These calls can be removed in the future when the Font Manager can be superceded. BUG=skia:2687 Rfirstname.lastname@example.org Review URL: https://codereview.chromium.org/407183003
