Struct opengl_graphics::Texture
[−]
[src]
pub struct Texture {
// some fields omitted
}Wraps OpenGL texture data. The texture gets deleted when running out of scope.
In order to create a texture the function GenTextures must be loaded.
This is done automatically by the window back-ends in Piston.

fn new(id: GLuint, width: u32, height: u32) -> Self

fn get_id(&self) -> GLuint
Gets the OpenGL id of the texture.
fn from_memory_alpha(buf: &[u8], width: u32, height: u32) -> Result<Self, String>
Loads image from memory, the format is 8-bit greyscale.
fn from_path(path: &Path) -> Result<Self, String>

fn from_image(img: &RgbaImage) -> Self

fn update(&mut self, img: &RgbaImage)
