Usage

Decoding

Simple method for single images

import pyFLIF

img = pyFLIF.imread( "path_to/image.flif" ) # numpy array with shape [ WxH(x3/4) ]

Advanced method also for animations

import pyFLIF

with pyFLIF.flifDecoder( "path_to/file.flif" ) as dec:
    # decompressing all frames and storing them in a list
    allframes = [ dec.getImage(idx) for idx in xrange(dec.numImages())

Encoding

Simple method for single images

import pyFLIF

# img: numpy array with shape [ WxH(x3/4 ]
# dtype in (uint8, uint16)
pyFLIF.imwrite( "path_to/image.flif", img ) 

Advanced method also for animations

import pyFLIF

with pyFLIF.flifEncoder( "path_to/file.flif" ) as enc:
    for img in <image source>:
	    # all img shall have same shape [ WxH(x3/4) ] and dtype (uint8/uint16)
	    enc.addImage( img )]
