| 14 /* If your system embeds skia and has complex event logging, in | |
| 15 src/config/SkUserConfig.h: | |
| 16 - define the three SK_TRACE_EVENT macros to map to your system's | |
| 17 equivalents, | |
| 18 - define the name of the include file in SK_USER_TRACE_INCLUDE_FILE | |
| 19 A trivial example is given in src/utils/SkDebugTrace.h. | |
| 20 | |
| 21 All arguments are const char*. Skia typically passes the name of | |
| 22 the object and function (and sometimes region of interest within | |
| 23 the function) separated by double colons for 'event'. | |
| 24 | |
| 25 SK_TRACE_EVENT1 and SK_TRACE_EVENT2 take one or two arbitrary | |
| 26 name-value pairs that you also want to log. SkStringPrintf() is useful | |
| 27 for formatting these values. | |
| 28 | |
| 29 For example: | |
| 30 SK_TRACE_EVENT0("GrContext::createAndLockTexture"); | |
| 31 SK_TRACE_EVENT1("GrDefaultPathRenderer::onDrawPath::renderPasses", | |
| 32 "verts", SkStringPrintf("%i", vert - base).c_str()); | |
