| Overview |
| -------- |
| |
| Each test in the gm directory draws a reference image. Their primary purpose is |
| to detect when images change unexpectedly, indicating that a rendering bug has |
| been introduced. |
| |
| The gm tests have a secondary purpose: they detect when rendering is different |
| across platforms and configurations. |
| |
| GM font selection |
| ----------------- |
| |
| Each gm specifies the typeface to use when drawing text. For now, to set the |
| portable typeface on the paint, call: |
| |
| ~~~~ |
| ToolUtils::set_portable_typeface(SkPaint* , const char* name = nullptr, |
| SkFontStyle style = SkFontStyle()); |
| ~~~~ |
| |
| To create a portable typeface, use: |
| |
| ~~~~ |
| SkTypeface* typeface = ToolUtils::create_portable_typeface(const char* name, |
| SkFontStyle style); |
| ~~~~ |
| |
| Eventually, both `set_portable_typeface()` and `create_portable_typeface()` will be |
| removed. Instead, a test-wide `SkFontMgr` will be selected to choose portable |
| fonts or resource fonts. |
