Struct opengl_graphics::Texture

pub struct Texture { /* 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.

Methods

impl Texture

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

Creates a new texture.

pub fn get_id(&self) -> GLuint

Gets the OpenGL id of the texture.

pub fn empty(settings: &TextureSettings) -> Result<Self, String>

Returns empty texture.

pub fn from_memory_alpha(     buf: &[u8],     width: u32,     height: u32,     settings: &TextureSettings ) -> Result<Self, String>

Loads image from memory, the format is 8-bit greyscale.

pub fn from_path<P>(path: P, settings: &TextureSettings) -> Result<Self, String> where     P: AsRef<Path>,

Loads image by relative file name to the asset root.

pub fn from_image(img: &RgbaImage, settings: &TextureSettings) -> Self

Creates a texture from image.

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

Updates image with a new one.

Trait Implementations

impl CreateTexture<()> for Texture

type Error = String

The error when creating texture.

fn create<S: Into<[u32; 2]>>(     _factory: &mut (),     _format: Format,     memory: &[u8],     size: S,     settings: &TextureSettings ) -> Result<Self, Self::Error>

impl UpdateTexture<()> for Texture

type Error = String
