Module lodepng::ffi

Structs

• ColorMode
  Color mode of an image. Contains all information required to decode the pixel bits to RGBA colors. This information is the same as used in the PNG file format, and is used both for PNG and raw image data in LodePNG.
• ColorProfile
  Gives characteristics about the colors of the image, which helps decide which color model to use for encoding. Used internally by default if auto_convert is enabled. Public because it’s useful for custom algorithms.
• CompressSettings
  Settings for zlib compression. Tweaking these settings tweaks the balance between speed and compression ratio.
• DecoderSettings
  Settings for the decoder. This contains settings for the PNG and the Zlib decoder, but not the Info settings from the Info structs.
• DecompressSettings
• EncoderSettings
• ErrorCode
• Info
  Information about the PNG image, except pixels, width and height
• State
  The settings, state and information for extended encoding and decoding
• Time
  The information of a Time chunk in PNG

Enums

• ColorType
  Type for decode, encode, etc. Same as standard PNG color types.
• FilterStrategy
  automatically use color type with less bits per pixel if losslessly possible. Default: AUTO

Type Aliases

• custom_compress_callback
• custom_decompress_callback
