Member Function Documentation

template<typename T> void PortablePicture< T >::getRange (  T &    our_min, T &    our_max )  [inline]

Get the minimum and maximum storable color value. For unsigned byte, this is 0 to 255; for a float, it is 0 and 1.0. Definition at line 141 of file PortablePicture.h. Referenced by PortablePicture< unsigned char >::loadFile().

template<typename T> void PortablePicture< T >::loadFile (  const char *    filename )  [inline]

loadFile: try to load a picture file. Right now, this just handles the normal PortableXMaps, with the exception of PBM binary files (ie the "P4" kind), which we don't handle yet. Definition at line 161 of file PortablePicture.h.

template<typename T> void PortablePicture< T >::saveAs (  const char *    filename )  const [inline]

Saves the image to a file. The "bAscii" param indicates whether the file should be saved as ascii, as opposed to binary. Supported extensions are .pfm, .ppm, and .pgm. Definition at line 299 of file PortablePicture.h.
