Methods from Deref<Target = Canvas<ID>>
pub fn renderer<'a>(&'a mut self) -> Result<CanvasRenderer<'a, ID>, Error>
[src]
Make the canvas "paint ready" and return an object to paint to it. In very very very rare case, the renderer creation can fail.
pub fn create_solid_brush(
&mut self,
name: &ID,
brush: &SolidBrush
) -> Result<(), Error>
[src]
&mut self,
name: &ID,
brush: &SolidBrush
) -> Result<(), Error>
Create a solid brush into the canvas and add it under the selected name
.
Errors:
• Error::System
if the canvas could not create the brush.
• Error::KeyExists
if the a resource with the specified name already exists
pub fn create_pen(&mut self, name: &ID, pen: &Pen) -> Result<(), Error>
[src]
Create a pen into the canvas and add it under the selected name
.
Errors:
• Error::System
if the canvas could not create the brush.
• Error::KeyExists
if the a resource with the specified name already exists
pub fn redraw(&self)
[src]
Redraw the canvas
pub fn set_render_size(&mut self, w: u32, h: u32)
[src]
Set the render target resolution.
If the control size do not match the render target size, the result will be upscaled or downscaled

[src]
Return the render target's dots per inch (DPI).
pub fn set_dpi(&mut self, dpix: f32, fpiy: f32)
[src]
Sets the dots per inch (DPI) of the render target.
Arguments:
• dpix
: A value greater than or equal to zero that specifies the horizontal DPI of the render target.
• dpiy
