Member Function Documentation

virtual bool OD::RGBImage::blendWith ( const RGBImage &  sourceimage, bool  blendtransparency = false, unsigned char  blendtransparencyval = 0, bool  blendequaltransparency = false, bool  with_opacity = false  )

virtual

Fills image with data from array.param xdir_slowest False if ydir is the slowest dimension, param with_opacity If true, eventual 4th component will be treated as a opacity instead of a transparency. Blends image with another image of same size. The provided images' transparency will be used to blend the two images proportionally.

Parameters

blendtransparency	if true, the color will be blended by source image's color if the transparency equal to the param blendtransparencyval.
blendequaltransparency	if false,the color will be not blended when sourceimage has same transparency as this image has.
with_opacity	if true,eventual 4th component will be treated as a opacity instead of a transparency.

virtual bool OD::RGBImage::put ( const unsigned char *  , bool  xdir_slowest = true, bool  with_opacity = false  )

virtual

Fills array with content. Each pixel's components are the fastest dimension, slowest is xdir. Caller must ensure sufficient mem is allocated.
