}

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.

Errors

Returns an error when the destination cannot accept the 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.

Errors

Returns an error when the destination cannot accept the component 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.

Errors

Returns an error when the destination cannot accept the component row.

Dyn Compatibility

This trait is dyn compatible.

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