apftool 0.5.1

Encoder and decoder for Aperture Science Image Format (apf), Aperture Science Image Format 2 (apf2), Wireless Bitmap (wbmp), Over-The-Air Bitmap (otb), and FaceDev's .bruh format

A library for converting to and from Aperture Science apf files, the custom extended apf2s, otb/wbmp images, and facedev's bruh format.

basic usage:

import apftool

apfString = apftool.encodeapf(pngObject) # turns image bytes object into apf string
pngObject = apftool.decodeapf(apfString) # turns apf string object into image bytes

funcs and features

encoders:

encodeapf(img: bytes, lineskip: int = 1, findbestlineskip: bool = False) takes image bytes and outputs apf string. lineskip is interleave value, findbestlineskip brute-forces different interleave values to the possible max of 199 and uses the smallest one.

encodeaf2(img: bytes, lineskip: int = 1, findbestlineskip: bool = False, legacy: bool = False, trans: bool = False, pal: int = 95) takes image bytes and outputs af2 string. lineskip is interleave value, findbestlineskip brute-forces different interleave values to the provided lineskip and uses the smallest one. legacy uses apf1-style 1 color data instead of a 95 color palette. trans enables/disables transparency, which overrides a color. pal allows you to manually force a smaller palette.

encodewbmp(img: Image) takes pil image object and outputs wbmp bytes

encodeotab(img: Image, width=255, height=255) takes pil image object and outputs otb bytes. max size is 255x255. the size input is max size, the output may be smaller

encodebruh(img: Image) takes pil image object and outputs bruh bytes

decoders:

decodeany(data, format: str = 'PNG', returnImageObject: bool = False) takes in string or bytes and outputs bytes image or PIL image using best-guess for the decoders

decodeapf(apf: str, format: str = 'PNG', returnImageObject: bool = False) takes apf string and outputs either image bytes in specified format or pil image object

decodeaf2(af2: str, format: str = 'PNG', returnImageObject: bool = False) hi i am the same thing, i am literally a dropin replacement for decodeapf too

decodewbmp(wbmp: bytes, format: str = 'PNG', returnImageObject: bool = False) takes wbmp bytes and outputs either image bytes in specified format or pil image object

decodeotab(otab: bytes, format: str = 'PNG', returnImageObject: bool = False) hi i have the same usage as decodewbmp but for .otb images

decodebruh(bruh: bytes, format: str = 'PNG', returnImageObject: bool = False) bruh decoder

misc:

apftool provides many extensions tuples:

extensions - apf/apf2 extensions

extensions_apf - apf extensions

extensions_apf2 - apf2 extensions

extensions_wbmp - wbmp extensions

extensions_otab - otb extensions

extensions_bruh - bruh extensions

extensions_txt - txt extensions, useful for weeding out generic apf

extensions_all - all supported apftool extensions, useful for decodeany

dependancies

PIL, io, textwrap, math (apftool)

most of these a builtins but you may need to install PIL seperately
