Member Function Documentation

void NL3D::CHLSColorTexture::addMask (  const NLMISC::CBitmap &    bmp,
uint    threshold = 15
) 
 

add a mask to the texture.

R is taken as the mask value. must be same size as in setBitmap()

Parameters:
threshold  used to know if a pixel mask value is or not an intermediate (ie not 0 or 255)

void NL3D::CHLSColorTexture::buildColorVersion (  const CHLSColorDelta *    colDeltaList,
NLMISC::CBitmap &    out
) 
 

build a texture with a HLS Color Delta.

Parameters:
colDelta  array of delta to apply to the bitmap (must be of numMasks entries)
out  a colorised bitmap with DXTC5/mipMaps generated
