}

Extension trait for io::Cursor to add pixel buffer specific operations

Required Methods

fn seek_to_pixel( &mut self, x: usize, y: usize, bytes_per_row: usize, ) -> Result<u64, Error>

Seek to a specific pixel coordinate (x, y)

Assumes 4 bytes per pixel (BGRA format).

Errors

Returns an I/O error if the seek operation fails.

fn read_pixel(&mut self) -> Result<[u8; 4], Error>

Read a single pixel (4 bytes: BGRA)

Errors

Returns an I/O error if the read operation fails.
