(Maximum / minimum of channels)

Functions
ImageBuf OIIO_API	ImageBufAlgo::maxchan (const ImageBuf &A, ROI roi={}, int nthreads=0)
bool OIIO_API	ImageBufAlgo::maxchan (ImageBuf &dst, const ImageBuf &A, ROI roi={}, int nthreads=0)
ImageBuf OIIO_API	ImageBufAlgo::minchan (const ImageBuf &src, ROI roi={}, int nthreads=0)
bool OIIO_API	ImageBufAlgo::minchan (ImageBuf &dst, const ImageBuf &src, ROI roi={}, int nthreads=0)

Detailed Description

maxchan() computes a one-channel image that for each pixel, contains the maximum value of all channels of corresponding pixel of the source image. minchan() similarly computes the minimum value of all channels.
