Read and Write PNG Files with Configurable Decoder/Encoder
Options
Description
Read and write PNG images with arrays, rasters, native
rasters, numeric arrays, integer arrays, raw vectors and indexed

and integer and numeric arrays at color depths of 1, 2, 3 or 4. 16-bit
images are also supported. This implementation uses the 'libspng' 'C'
library which is available from
