2018-04-20Add CPDF_PatternCS::GetPatternRGB(const PatternValue& value).chromium/3404chromium/3403chromium/3402Lei Zhang
Currently, one gets data from CPDF_PatternCS via its parent class's GetRGB(const float* pBuf) method. To squeeze through this interface, the caller has to pass in a float*, and CPDF_PatternCS::GetRGB() has to cast it to PatternValue*. Instead of doing casting, add a specialized GetPatternRGB() method to CPDF_PatternCS. In its parent class, CPDF_ColorSpace, add AsPatternCS() so callers can get a CPDF_PatternCS* from a CPDF_ColorSpace*. Change existing callers to use these new methods.
