Implementations

impl G2D

pub fn new<P>(path: P) -> Result<Self>

where P: AsRef<OsStr>,

pub fn version(&self) -> Version

pub fn clear(&self, dst: &mut G2DSurface, color: [u8; 4]) -> Result<()>

Clear a surface to a solid color using the hardware g2d_clear operation.

This queues the clear operation. Call finish() to wait for completion, or batch multiple operations before finishing.

pub fn blit(&self, src: &G2DSurface, dst: &G2DSurface) -> Result<()>

Blit (copy/scale/convert) from source to destination surface.

This queues the blit operation. Call finish() to wait for completion, or batch multiple operations before finishing.

pub fn finish(&self) -> Result<()>

Wait for all queued G2D operations to complete.

Must be called after clear() and/or blit() to ensure the hardware has finished writing.

pub fn flush(&self) -> Result<()>

Flush all queued G2D operations for asynchronous execution.

Unlike finish(), this does not wait for completion — the GPU begins processing immediately but the CPU continues. A subsequent finish() is still required before the CPU reads the destination buffer.

Useful in pipelines where the consumer of the result is not immediately ready, allowing GPU work to overlap with other CPU work.

pub fn set_bt601_colorspace(&mut self) -> Result<()>

pub fn set_bt709_colorspace(&mut self) -> Result<()>
