示例1: onGetPixels
virtual Result onGetPixels(const SkImageInfo& info, void* pixels, size_t rowBytes,
const Options&,
SkPMColor ctableEntries[], int* ctableCount) override {
SkMemoryStream stream(fData->data(), fData->size(), false);
SkAutoTUnref<BareMemoryAllocator> allocator(SkNEW_ARGS(BareMemoryAllocator,
(info, pixels, rowBytes)));
fDecoder->setAllocator(allocator);
fDecoder->setRequireUnpremultipliedColors(kUnpremul_SkAlphaType == info.alphaType());
SkBitmap bm;
const SkImageDecoder::Result result = fDecoder->decode(&stream, &bm, info.colorType(),
SkImageDecoder::kDecodePixels_Mode);
if (SkImageDecoder::kFailure == result) {
return kInvalidInput;
}
SkASSERT(info.colorType() == bm.info().colorType());
if (kIndex_8_SkColorType == info.colorType()) {
SkASSERT(ctableEntries);
SkColorTable* ctable = bm.getColorTable();

return kInvalidConversion;
}
const int count = ctable->count();
memcpy(ctableEntries, ctable->readColors(), count * sizeof(SkPMColor));
*ctableCount = count;
}

return kIncompleteInput;
}
return kSuccess;
}示例2: onDraw
void DecodingBench::onDraw(const int n, SkCanvas* canvas) {
SkBitmap bitmap;
// Declare the allocator before the decoder, so it will outlive the
// decoder, which will unref it.
UseExistingAllocator allocator(fBitmap.pixelRef());
SkAutoTDelete<SkImageDecoder> decoder;
SkAutoTDelete<SkStreamRewindable> stream;
for (int i = 0; i < n; i++) {
// create a new stream and a new decoder to mimic the behavior of
// CodecBench.
stream.reset(new SkMemoryStream(fData));
decoder.reset(SkImageDecoder::Factory(stream));
decoder->setAllocator(&allocator);
decoder->decode(stream, &bitmap, fColorType,
SkImageDecoder::kDecodePixels_Mode);
}
