Image

Bitmap types. Also contains valid values for <PixelType>

Functions

auto_choose_color	Automatically chooses color type that gives smallest amount of bits in the output image, e.g. grey if there are only greyscale pixels, palette if there are less than 256 colors, ...
convert	Converts from any color type to 24-bit or 32-bit (only)
decode24	Same as `decode_memory`, but always decodes to 24-bit RGB raw image
decode24_file	Same as `decode_file`, but always decodes to 24-bit RGB raw image
decode32	Same as `decode_memory`, but always decodes to 32-bit RGBA raw image
decode32_file	Same as `decode_file`, but always decodes to 32-bit RGBA raw image
decode_file	Load PNG from disk, from file with given name. Same as the other decode functions, but instead takes a file path as input.
decode_memory	Converts PNG data in memory to raw pixel data.
deflate	Compress a buffer with deflate. See RFC 1951.
encode24	Same as `encode_memory`, but always encodes from 24-bit RGB raw image
encode24_file	Same as `encode_file`, but always encodes from 24-bit RGB raw image
encode32	Same as `encode_memory`, but always encodes from 32-bit RGBA raw image
encode32_file	Same as `encode_file`, but always encodes from 32-bit RGBA raw image
encode_file	Converts raw pixel data into a PNG file on disk. Same as the other encode functions, but instead takes a file path as output.
encode_memory	Converts raw pixel data into a PNG image in memory. The colortype and bitdepth of the output PNG image cannot be chosen, they are automatically determined by the colortype, bitdepth and content of the input pixel data.
zlib_compress	Compresses data with Zlib. Zlib adds a small header and trailer around the deflate data. The data is output in the format of the zlib specification.
