Required Methods

fn write_image( self, buf: &[u8], width: u32, height: u32, color_type: ExtendedColorType ) -> ImageResult<()>

Writes all the bytes in an image to the encoder.

This function takes a slice of bytes of the pixel data of the image and encodes them. Unlike particular format encoders inherent impl encode methods where endianness is not specified, here image data bytes should always be in native endian. The implementor will reorder the endianness as necessary for the target encoding format.

See also ImageDecoder::read_image which reads byte buffers into native endian.

Panics

Panics if width * height * color_type.bytes_per_pixel() != buf.len().
