This works in a way that is similar to SkData.
SkMallocPixelRef::NewWithProc
Motivation: Chrome has a ETC1PixelRef which calls delete[] on the
pixles on destruction. There is no reason for them to almost
duplicate our class, when we can provide them a more flexible
class. Example use:
static void delete_uint8_proc(void* ptr, void*) {
delete[] static_cast<uint8_t>(ptr);
}
SkPixelRef* new_delete_pixref(const SkImageInfo& info,
SkColorTable* ctable) {
size_t rb = info.minRowBytes();
return SkMallocPixelRef::NewWithProc(
info, rb, ctable,
new uint8_t[info.getSafeSize(rb)],
delete_uint8_proc, NULL);
}
SkMallocPixelRef::NewWithData
Motivation: This allows up to eliminate SkDataPixelRef. We
modified SkImage_Raster to use MallocPixelRef rather than
SkDataPixlRef.
Also: Unit tests in tests/MallocPixelRefTest.
