[−][src]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`
