Struct PixelBuffer

pub struct PixelBuffer { /* private fields */ }

A wrapper around softbuffer to provide a soft buffer for pixel manipulation

Implementations

impl PixelBuffer

pub fn size(&self) -> Point2

Get the size of the soft buffer surface Returns the size of the soft buffer surface in pixels

pub fn write_buffers( &mut self, pixels: &[u32], size: Point2, ) -> Result<(), PixelBufferError>

Write pixels to the soft buffer surface
