void CEGUI::NeLTexture::loadFromFile	(	const String &	filename,
		const String &	resourceGroup
	)			`[virtual]`

void CEGUI::NeLTexture::loadFromMemory	(	const void *	buffPtr,
		uint	buffWidth,
		uint	buffHeight,
		PixelFormat	pixelFormat = `CEGUI::Texture::PF_RGBA`
	)			`[virtual]`

Creates a NeL Texture from a raw memory buffer.

Parameters:

	buffPtr	The pointer to the buffer containing the texture.
	buffWidth	The width of the texture in pixels.
	buffHeight	The height of the texture in pixels.
	pixelFormat	The type of pixel packing used.

Todo:: Clean up CTextureMem creation and registration.

This debugging is handy when you're not sure if the memory buffer being sent to you from CEGUI is valid. Uncomment it and it'll create a file called loadfrommem###.tga in your working directory.

NLMISC::CBitmap btm; btm.reset(); btm.resize(buffWidth,buffHeight,NLMISC::CBitmap::RGBA); uint8 *dest=&(btm.getPixels()[0]); memcpy(dest,buffPtr,buffWidth*buffHeight*4); std::string filename = NLMISC::CFile::findNewFile("loadfrommem.tga"); NLMISC::COFile fs(filename); btm.writeTGA(fs);

Configure the material. This is a little more complicated than loading a texture from a file, since CTextureFileUser and CTextureFile take care of prepping all of the necessary alpha settings.

We still use alpha testing to cull out pixels to speed up blending and multitexturing.
