Detailed Description

Reads images using the PNG format.

ImageReaderPNG is constructed with the name of the file to read. The data from the file is read by calling the ReadDataSet method.

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

By default, the colors are stored in a field named "colors", but the name of the field can optionally be changed using the SetPointFieldName method.
