Class PNMImageEncoder

java.lang.Object
  non_com.media.jai.codec.ImageEncoderImpl
      non_com.media.jai.codec.PNMImageEncoder

All Implemented Interfaces:: ImageEncoder

public class PNMImageEncoder
extends ImageEncoderImpl

An ImageEncoder for the PNM family of file formats.

The PNM file format includes PBM for monochrome images, PGM for grey scale images, and PPM for color images. When writing the source data out, the encoder chooses the appropriate file variant based on the actual SampleModel of the source image. In case the source image data is unsuitable for the PNM file format, for example when source has 4 bands or float data type, the encoder throws an Error.

The raw file format is used wherever possible, unless the PNMEncodeParam object supplied to the constructor returns true from its getRaw() method.
