Member Function Documentation

Image * halftoner::ImageIO::loadPGM (  std::istream &    is )  throw (ImageFormatError, IOError) [static]

Loads the specified PGM image. Parameters: is  the stream to load the image from Exceptions: ImageFormatError  if the data in the stream is not in PGM format. IOError  if I/O errors occur. Todo: i/o error checks. write better implementation (make sure delete data is called - use autor_ptr. Definition at line 38 of file ImageIO.cxx. References halftoner::Image::setColorAt().

ImageIO halftoner::ImageIO::operator= (  const ImageIO &    )  throw () [private]

Disable the assignement operator.

void halftoner::ImageIO::savePBMascii (  const Image &    image, std::ostream &    os )  throw (IOError) [static]

Saves the image in the PBM ascii format. Parameters: image  the image to save. os  the stream to send the data into. Exceptions: IOError  if I/O errors occur. Todo: i/o error checks. Definition at line 265 of file ImageIO.cxx.

void halftoner::ImageIO::savePBMraw (  const Image &    image, std::ostream &    os )  throw (IOError) [static]

Saves the image in the PBM raw format. Parameters: image  the image to save. os  the stream to send the data into. Exceptions: IOError  if I/O errors occur. Todo: make sure the output is correct and it is not ACDSee that is bugged. i/o error checks. Definition at line 218 of file ImageIO.cxx. References halftoner::Image::getCopy().
