The library provides scanline-, strip-, and tile-oriented interfaces that Provides interfaces to image data at several layers of abstraction (and cost).Īt the highest level image data can be read into an 8-bit/sample,ĪBGR pixel raster format without regard for the underlying data organization,Ĭolorspace, or compression scheme.
