	TextureLoader (void)
	Default constructor. Initializes variables and does nothing.
	~TextureLoader (void)
	Destructor. Frees image data, if an image has been loaded.
bool	load (BYTE *data, unsigned int width, unsigned int height, unsigned int bpp)
	Load an image from memory.
unsigned int	getWidth (void)
	Returns the width of the image.
unsigned int	getHeight (void)
	Gets the height of the image.
unsigned int	getBPP (void)
	Gets the bits per pixel of the image. This is usually 24 or 32.

bool	isBGR (void)
	Trys to decide, if BGR is the appropriate ording for the format of the current image.
void	toRGB (void)
	Converts the image from BGR to RBG, if the image data is in BGR ordering.
void	toBGR (void)
	Converts the image from RGB to BGR, if the image data is in RGB ordering.

Detailed Description

An implementation of the TextureLoader that can load windows bitmaps.

This class is basically an extension to the TextureLoader class which is capable to load bitmap textures. Therefore it overloads the load method of the base class. If this doesn't work the GLaux functions could be used as some kind of rescue.

Member Function Documentation

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

virtual

Loads a bitmap.

It is currently only able to load windows bitmaps. It tests if the filetype is correct and calls the corresponding method.

Parameters

filename

zero terminated character array as filename

Implements TextureLoader.

Definition at line 51 of file TextureLoaderBMP.cpp.

AUX_RGBImageRec * TextureLoaderBMP::loadAux ( const char *  filename )

static

Loads a Windows bitmap using auxDIBImageLoad function from the GLaux lib.

Returns

A pointer to a AUX_RGBImageRec structure if loading was successful or NULL elsewise.

Parameters

filename

pointer to the file to load

Definition at line 29 of file TextureLoaderBMP.cpp.

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

virtual

Does nothing, because writing bitmaps is not supported.

Implements TextureLoader.

Definition at line 241 of file TextureLoaderBMP.cpp.
