Detailed Description

Helper class used for YUV to RGB conversions.

This class can take into account different source/destination primaries and various other parameters.

Member Function Documentation

GetGammaDst()

float CConvertMatrix::GetGammaDst

(

)

Get the gamma destination value.

Used for color primary conversion.

GetGammaSrc()

float CConvertMatrix::GetGammaSrc

(

)

Get the gamma source value.

Used for color primary conversion..

SetSourceTextureBitDepth()

CConvertMatrix & CConvertMatrix::SetSourceTextureBitDepth

(

int

textureBits

)

Set the source texture bit depth.

This is need to normalize values when using > 8 bit texture formats in OpenGL/DirectX. For example GL_R16 is a 16 bit texture which needs to normalize the 10 bit format.
