Receives decoded component rows before they are packed into the final interleaved pixel format.

Required Methods

fn write_gray_row(&mut self, y: u32, gray_row: &[u8]) -> Result<(), JpegError>

Receive one grayscale row.

fn write_ycbcr_row( &mut self, y: u32, y_row: &[u8], cb_row: &[u8], cr_row: &[u8], ) -> Result<(), JpegError>

Receive one full-width Y/Cb/Cr row.

fn write_rgb_row( &mut self, y: u32, r_row: &[u8], g_row: &[u8], b_row: &[u8], ) -> Result<(), JpegError>

Receive one full-width planar RGB row.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
