Detailed Description

template<typename InputBuffer, typename OutputBuffer = rle_targa_output_buffer<InputBuffer>>
class claw::graphic::targa::reader::rle_targa_decoder< InputBuffer, OutputBuffer >

RLE decoder for targa RLE format.

Template parameters :

• Pixel, the type of the pixels in the file.
• OutputBuffer, the type of the output buffer.

The OutputBuffer type must match the type requirements of the template parameter OutputBuffer of the rle_decoder class.
