Function Documentation

template<class SrcIterator, class SrcAccessor, class AlphaIterator, class AlphaAccessor> void exportImageAlpha (  vigra::triple< SrcIterator, SrcIterator, SrcAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha, vigra::ImageExportInfo const &  info )

export an image with a differently typed alpha channel. This function handles the merging of the images and the scales the alpha channel to the correct values. can write to all output formats that support 4 channel images. (currently only png and tiff).

template<class SrcIterator, class SrcAccessor, class AlphaIterator, class AlphaAccessor> void exportImageAlpha (  vigra::triple< SrcIterator, SrcIterator, SrcAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha, vigra::ImageExportInfo const &  info, vigra::VigraFalseType  )

template<class SrcIterator, class SrcAccessor, class AlphaIterator, class AlphaAccessor> void exportImageAlpha (  vigra::triple< SrcIterator, SrcIterator, SrcAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha, vigra::ImageExportInfo const &  info, vigra::VigraTrueType  )

template<class DestIterator, class DestAccessor, class AlphaIterator, class AlphaAccessor> void importImageAlpha (  vigra::ImageImportInfo const &  info, vigra::pair< DestIterator, DestAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha )

import an image with a differently typed alpha channel. This function loads an image, and splits it into a color image and a separate alpha channel, the alpha channel should be a 8 bit image. If the image doesn't contain any alpha channel, a completely white one is created. can write to all output formats that support 4 channel images. (currently only png and tiff).

template<class DestIterator, class DestAccessor, class AlphaIterator, class AlphaAccessor> void importImageAlpha (  vigra::ImageImportInfo const &  info, std::pair< DestIterator, DestAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha, vigra::VigraTrueType  )

template<class DestIterator, class DestAccessor, class AlphaIterator, class AlphaAccessor> void importImageAlpha (  vigra::ImageImportInfo const &  info, std::pair< DestIterator, DestAccessor >  image, std::pair< AlphaIterator, AlphaAccessor >  alpha, vigra::VigraFalseType  )
