Detailed Description

The ITextureMap represents a texture map object in memory.

Member Function Documentation

virtual signed int ITextureMap::AskInterface	(	const BGUID *	piid,
		IRoot **	ppr
	)

pure virtual

Queries this object to see if the interface piid is supported and returns the result in ppr.

Parameters

piid	The BGUID of the requested interface.
ppr	The address of an IRoot pointer which will receive the new interface.

Implements IRoot.

virtual signed int ITextureMap::DecRef ( )

pure virtual

Decreases the reference count on this object by 1. If the reference count reaches 0, the object is deallocated.

Implements IRoot.

virtual signed int ITextureMap::GetBitsPerPixel ( unsigned int * pBPP )

pure virtual

Returns bit depth (bits per pixel) of the texture. Currently all textures are internally converted to 32 bpp RGBA.

virtual signed int ITextureMap::GetBuffer ( unsigned char ** pBuffer )

pure virtual

Returns a pointer to the raw image data.

virtual signed int ITextureMap::GetDimensions	(	unsigned int *	pWidth,
		unsigned int *	pHeight
	)

pure virtual

Returns the width and height of the texture in pixels.

virtual signed int ITextureMap::IncRef ( )

pure virtual

Increases the reference count on this object by 1. You do not need to call this after an object is first created. It is 1 by default.

Implements IRoot.

virtual signed int ITextureMap::LoadTextureMap ( char * fileName )

pure virtual

Loads a texture map.
