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

Member Function Documentation

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

Create the texture.

If this function fails, the texture is left unchanged.

Parameters
sizeSize of the texture
Returns
True if creation was successful
