Canvas

Behave like Texture but you can render onto it. Use pushCanvas/popCanvas to start the drawing region on it.

Functions

copy Canvas copy(Canvas canvas): Copy
draw void draw(Vec2f pos, Vec2f anchor): Draw the texture at the specified location. Render the whole texture here
draw void draw(Vec2f pos, Vec4i srcRect, Vec2f anchor): Render a section of the texture here
draw void draw(Vec2f pos, Vec2f size, Vec2f anchor): Render the whole texture here
draw void draw(Vec2f pos, Vec2f size, Vec4i srcRect, Vec2f anchor): Render a section of the texture here
draw void draw(Vec2f pos, Vec2f size, Vec4i srcRect, float angle, Flip flip, Vec2f anchor): Render a section of the texture here
setSmooth void setSmooth(bool isSmooth_): Toggle the canvas smoothing

Properties

alpha float alpha [@property getter]
float alpha [@property setter]: Alpha
blend Blend blend [@property getter]
Blend blend [@property setter]: Blending algorithm.
color Color color [@property getter]
Color color [@property setter]: Color added to the canvas.
height uint height [@property getter]: Height in texels.
isLoaded bool isLoaded [@property getter]: loaded ?
renderSize Vec2i renderSize [@property getter]
Vec2i renderSize [@property setter]: The size (in texels) of the surface to be rendered on. Changing that value allocate a new texture, so don't do it everytime.
target const(SDL_Texture*) target [@property getter]: Undocumented in source. Be warned that the author may not have intended to support it.
width uint width [@property getter]: Width in texels.

Variables

_isTargetOnStack bool _isTargetOnStack;: Undocumented in source.
clearAlpha float clearAlpha;: The base opacity when nothing is rendered.
clearColor Color clearColor;: The base color when nothing is rendered.
flip Flip flip;: Mirroring property.
position Vec2f position;: The view position inside the canvas. +//// The size of the view inside of the canvas
size Vec2f size;: The view position inside the canvas.
