1.17 +/* If your system embeds skia and has complex event logging, in
1.18 + src/config/SkUserConfig.h:
1.19 + - define the three SK_TRACE_EVENT macros to map to your system's
1.20 + equivalents,
1.21 + - define the name of the include file in SK_USER_TRACE_INCLUDE_FILE
1.22 + A trivial example is given in src/utils/SkDebugTrace.h.
1.23 +
1.24 + All arguments are const char*. Skia typically passes the name of
1.25 + the object and function (and sometimes region of interest within
1.26 + the function) separated by double colons for 'event'.
1.27 +
1.28 + SK_TRACE_EVENT1 and SK_TRACE_EVENT2 take one or two arbitrary
1.29 + name-value pairs that you also want to log. SkStringPrintf() is useful
1.30 + for formatting these values.
1.31 +
1.32 + For example:
1.33 + SK_TRACE_EVENT0("GrContext::createAndLockTexture");
1.34 + SK_TRACE_EVENT1("GrDefaultPathRenderer::onDrawPath::renderPasses",
1.35 + "verts", SkStringPrintf("%i", vert - base).c_str());
