Detailed Description

An implementation of the TextureLoader that can load Targa files.

This class is basically an extension to the TextureLoader class which is capable to load targa files. Therefore it overloads the load method of the base class.

Member Function Documentation

bool TextureLoaderTGA::load ( const std::string &  filename )

virtual

Loads a Targa image from disk.

This function loads a targa file. Currently only uncompressed files are supported.

Parameters

filename

String with the filename

Returns

True if the loading was successful

Implements TextureLoader.

Definition at line 29 of file TextureLoaderTGA.cpp.

bool TextureLoaderTGA::write ( const std::string &  filename )

virtual

Writes a Targa file.

Writes an uncompressed targa file. This could be used to make screenshots.

Parameters

filename

String containing the filename

Returns

True if the writing was successful.

Implements TextureLoader.
