`gnome.utilities.images2gif`¶

MODULE images2gif

Provides a function (writeGif) to write animated gif from a series of PIL images or numpy arrays.

Added as a handy utility to the py_gnoe code.

Adapted form code from:

Almar Klein (June 2009)

This code is provided as is, and is free to use for all.

Module Contents¶

`intToBin`(i)	Integer to two bytes
`getheaderAnim`(im)	Animation header. To replace the getheader()[0]
`getAppExt`([loops])	Application extention. Part that secifies amount of loops.
`getGraphicsControlExt`([duration])	Graphics Control Extension. A sort of header at the start of
`_writeGifToFile`(fp, images, durations, loops)	Given a set of images writes the bytes to the specified stream.
`writeGif`(filename, images[, duration, loops, dither])	writeGif(filename, images, duration=0.1, loops=0, dither=1)

gnome.utilities.images2gif.getheaderAnim(im)¶: Animation header. To replace the getheader()[0]

gnome.utilities.images2gif.getAppExt(loops=0)¶: Application extention. Part that secifies amount of loops. if loops is 0, if goes on infinitely.

gnome.utilities.images2gif.getGraphicsControlExt(duration=0.1)¶: Graphics Control Extension. A sort of header at the start of each image. Specifies transparancy and duration.

gnome.utilities.images2gif._writeGifToFile(fp, images, durations, loops)¶: Given a set of images writes the bytes to the specified stream.

gnome.utilities.images2gif.writeGif(filename, images, duration=0.1, loops=0, dither=1)¶: writeGif(filename, images, duration=0.1, loops=0, dither=1) Write an animated gif from the specified images. images should be a list of numpy arrays of PIL images. Numpy images of type float should have pixels between 0 and 1. Numpy images of other types are expected to have values between 0 and 255.
