示例1: KeyForDstRead
GrGLShaderBuilder::DstReadKey GrGLShaderBuilder::KeyForDstRead(const GrTexture* dstCopy,
const GrGLCaps& caps) {
uint32_t key = kYesDstRead_DstReadKeyBit;
if (GrGLCaps::kNone_FBFetchType != caps.fbFetchType()) {
return key;
}
SkASSERT(NULL != dstCopy);
if (!caps.textureSwizzleSupport() && GrPixelConfigIsAlphaOnly(dstCopy->config())) {
// The fact that the config is alpha-only must be considered when generating code.
key |= kUseAlphaConfig_DstReadKeyBit;
}
if (kTopLeft_GrSurfaceOrigin == dstCopy->origin()) {
key |= kTopLeftOrigin_DstReadKeyBit;
}
SkASSERT(static_cast<DstReadKey>(key) == key);
return static_cast<DstReadKey>(key);
}
