[−][src]Trait leafrender::render::Drawer
Structures for rendering stuff to the screen
Associated Types
type NativeTexture: Sized + Dimensions
Required methods
fn start(&mut self)
Starts a particular rendering frame
fn end(&mut self)
Ends a frame, requesting for framebuffers to be finalised/etc
fn clear(&mut self, transparent: bool)
Clears the frame. transparent: If the frame should be cleared to alpha 0.
fn enable_blending(&mut self)
Enables blending of a texture/etc with the background, if this is explicitly required.
fn convert_image(&mut self, texture: &RgbaImage) -> Self::NativeTexture
Converts an RGBA image to a native image.
fn convert_native_texture(&mut self, texture: Texture) -> Self::NativeTexture
Converts a texture to a native reference.
fn get_width(&self) -> usize
Returns the width of the framebuffer.
fn get_height(&self) -> usize
Returns the height of the framebuffer.
fn set_background(&mut self, image: DynamicImage)
Uses the specified image as a background. This is provided as several platforms have ways to accelerate this beyond OpenGL calls.
fn set_brightness(&mut self, brightness: u8) -> Result<()>
Sets the screen brightness, if possible. Ignore call if not.
fn draw_textured_vertices_colored_uv(
&mut self,
texture: &Self::NativeTexture,
vertices: &[f32],
colors: &[f32],
uv: &[f32]
)
&mut self,
texture: &Self::NativeTexture,
vertices: &[f32],
colors: &[f32],
uv: &[f32]
)
Draws a texture to the screen, with a specified set of vertices to draw to, a UV to decode the image with, and a color to use as a base.
fn draw_colored_vertices(&mut self, vertices: &[f32], colors: &[f32])
Draws a set of colored vertices to the screen, with a specified color array.
fn get_transition_count(&self) -> usize
Returns the count of transitions that occured so far in this frame.
fn new(title: &str, width: u32, height: u32) -> Result<Self, String> where
Self: Sized,
Self: Sized,
Creates a new instance of this drawer.
All parameters are handled only if the target platform handles them.
