Struct Texture

pub struct Texture { /* private fields */ }

Texture is wrapper for opengl texture object its just an unsafe pointer with useful methods

Implementations

impl Texture

pub const NONE: Self

pub fn default(path: &str) -> Result<Texture, ImageError>

default creates what i consider default texture from provided path (no interpolation, alfa channel)

pub fn empty_texture(size: TextureSize, config: TextureConfig) -> Self

empty texture creates texture with all pixels set to 0. its useful mainly for canvas.

pub fn new<P: AsRef<Path>>( path: P, config: TextureConfig, ) -> Result<Texture, ImageError>

new creates new texture. for mode you have two options:

• gl::NEAREST - it makes pixels visible
• gl::LINEAR - it linearly interpolates between pixels and generally looks little ugly

pub fn from_img(img: &DynamicImage, config: TextureConfig) -> Texture

from_img returns texture from provided DynamicImage in case you want to do some pre processing on texture

pub fn from_raw_data( size: TextureSize, bytes: *const u8, config: TextureConfig, mipmap: bool, ) -> Texture

its just lower level function, it may come handy

pub fn resize_and_clear(&mut self, size: TextureSize)

resize_and_clear si here purely for resizing canvas textures, otherwise not very useful because it also erases the content of a texture.

pub fn to_image<P: Pixel<Subpixel = u8> + 'static>( &self, ) -> Option<ImageBuffer<P, Vec<u8>>>

to image takes texture from gpu memory to back to you so you can save texture

pub fn size(&self) -> Vect

pub fn frame(&self) -> Rect

frame returns bounding rectangle of texture useful for sprite

pub fn id(&self) -> GLuint

id returns texture id. its a pointer to gl texture object

pub fn bind(&self)

set used uses ah texture

pub fn unbind()

Trait Implementations

impl Clone for Texture

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for Texture

fn drop(&mut self)

Executes the destructor for this type.
