pub struct PngEncoder { /* private fields */ }

PNG encoder.

Implementations

impl PngEncoder

pub fn new() -> Self

Create a new PNG encoder with default configuration.

pub const fn with_config(config: EncoderConfig) -> Self

Create a new PNG encoder with custom configuration.

pub fn encode_rgba( &self, width: u32, height: u32, data: &[u8], ) -> CodecResult<Vec<u8>>

Encode RGBA image data to PNG format.

Arguments

• width - Image width in pixels
• height - Image height in pixels
