Required Methods
The Graphics that draws to this texture.
Reads pixels out from the given region. This is potentially a very SLOW operation, avoid overusing it.
@returns A byte buffer in RGBA order.
Writes pixels at a given position. sourceW/H is the width and height of the given byte buffer. This is potentially a very SLOW operation, avoid overusing it.
@param pixels A byte buffer in RGBA order.
fn sub_texture(
&self,
x: i32,
y: i32,
width: i32,
height: i32
) -> Rc<dyn SubTexture + 'static>
fn sub_texture(
&self,
x: i32,
y: i32,
width: i32,
height: i32
) -> Rc<dyn SubTexture + 'static>
Creates a SubTexture that displays a region of this texture.
The returned sub-texture is only a “view”, so any changes to the parent texture will affect its regions. Repeatedly nested sub-textures are allowed.
NOTE: The graphics instance of the sub-texture is the same as its parent. This means you
may need to translate() first when working with sub-textures, and take care not to conflict
with other textures’ graphics.
@param x The X offset of the region. @param y The Y offset of the region. @param width The width of the region. @param height The height of the region.
Splits this texture into multiple tiles using sub_texture().
@param tilesWide The width, in number of tiles. @param tilesHigh The height, in number of tiles.
