[−][src]Struct druid::piet::BitmapTarget
A struct provides a RenderContext and then can have its bitmap extracted.
Implementations
impl<'a> BitmapTarget<'a>[src]
pub fn render_context(&mut self) -> D2DRenderContext[src]
Get a piet RenderContext for the bitmap.
Note: caller is responsible for calling finish on the render
context at the end of rendering.
pub fn into_raw_pixels(self, fmt: ImageFormat) -> Result<Vec<u8>, Error>[src]
Get raw RGBA pixels from the bitmap.
pub fn save_to_file<P>(self, path: P) -> Result<(), Error> where
P: AsRef<Path>, [src]
P: AsRef<Path>,
Save bitmap to RGBA PNG file
