Image< byte > PnmParser::Rep::parseBW

(

)

Parse a 1-bit black+white raw or ascii image file into an 8-bit image.

The underlying file must be a black_white file (mode 1 or 4).

Image< uint16 > PnmParser::Rep::parseGrayU16

(

)

Parse a 16-bit grayscale image in either raw or ascii mode.

The underlying file must be a grayscale file (mode 2 or 5).
