Detailed Description

A texture with a single alpha channel.

This texture is used internally by gf::Font

Constructor & Destructor Documentation

gf::AlphaTexture::AlphaTexture ( )

Constructor.

No texture is created

bool gf::AlphaTexture::create ( Vector2u size )

Create the texture.

If this function fails, the texture is left unchanged.

Parameters

size	Size of the texture
