Description

Parsing the netpbm image formates (PBM, PGM and PPM, both ASCII and binary) from ByteStrings.

All netpbm image formats are implemented (P1 - P6).

To parse one of these formats, use parsePPM.

pixelVectorToList :: Storable a => Vector a -> [a] #

Converts a vector of pixels to a list for convenience.

pixelDataToIntList :: PpmPixelData -> [Int] #

Converts pixel data to a list of positive Ints.

How big they can become depends on the bit depth of the pixel data.

parsePPM :: ByteString -> PpmParseResult #

Parses a PPM file from the given ByteString. On failure, Left error contains the error message. On success, Right (images, Maybe rest) contains the parsed images and potentially an unparsable rest input.

type PpmParseResult = Either String ([PPM], Maybe ByteString) #

The result of a PPM parse.
