Member Data Documentation

SoMFImagei32 SoColTabTextureChannel2RGBA::colorsequences

Colorsequences for all images. The colorsequence is an 1-dimensional image where the size in dim0 and dim1 are 1.

SoElement* SoColTabTextureChannel2RGBA::matchinfo_ [protected]

bool SoColTabTextureChannel2RGBA::needsregeneration_ [protected]

SoMFShort SoColTabTextureChannel2RGBA::opacity

Specifies the maximum opacity of each image. 0 is completely transperant, 255 is completely opaque.
