Detailed Description

Manages reading images using the PNG format via lodepng.

ImageReaderPNG extends ImageReaderBase and implements reading images in a valid PNG format. It utilizes lodepng's decode file functions to read PNG images that are automatically compressed to optimal sizes relative to the actual bit complexity of the image.

ImageReaderPNG will automatically upsample/downsample read image data to a 16 bit RGB no matter how the image is compressed. It is up to the user to decide the pixel format for input PNGs
