Expand description

Optimizes a WebP image with configurable quality and lossless options.

This function uses Google’s WebP encoder to create optimized WebP images. It supports both lossy compression with quality control and lossless compression mode for maximum quality preservation.

§Arguments

  • input_path - Path to the source WebP file
  • output_path - Path where the optimized WebP will be written
  • args - CLI configuration containing quality settings and lossless flag
  • resized_img - Optional pre-resized image data; if None, reads from input_path

§Returns

Returns Ok(()) on successful optimization.

§Errors

Returns an error if:

  • WebP encoding fails
  • File I/O operations fail (reading input or writing output)
  • Image format conversion to RGB8 fails
