C++ (Cpp) MakeRasterData示例

示例#1

文件： SkImage_Gpu.cpp 项目： aseprite/skia

sk_sp<SkImage> SkImage::makeNonTextureImage() const {
    if (!this->isTextureBacked()) {
        return sk_ref_sp(const_cast<SkImage*>(this));
    }
    SkImageInfo info = as_IB(this)->onImageInfo();
    size_t rowBytes = info.minRowBytes();
    size_t size = info.getSafeSize(rowBytes);
    auto data = SkData::MakeUninitialized(size);
    if (!data) {
        return nullptr;
    }

        return nullptr;
    }
    return MakeRasterData(info, data, rowBytes);
