Type Definition imgref::ImgRef [−][src]
type ImgRef<'a, Pixel> = Img<&'a [Pixel]>;
Reference to pixels inside another image.
Pass this structure by value (i.e. ImgRef, not &ImgRef).
Only width of pixels of every stride can be modified. The buf may be longer than height*stride, but the extra space should be ignored.

Note: it iterates all pixels in the underlying buffer, not just limited by width/height.
