# GIF-PIL Static and animated gif (Pillow)

Extensions: `.gif`

A format for reading and writing static and animated GIF, based on Pillow.

Images read with this format are always RGBA. Currently, the alpha channel is ignored when saving RGB images with this format.

## Parameters for reading

None

## Parameters for saving

loopint

  The number of iterations. Default 0 (meaning loop indefinitely).

duration{float, list}

  The duration (in seconds) of each frame. Either specify one value that is used for all frames, or one value for each frame. Note that in the GIF format the duration/delay is expressed in hundredths of a second, which limits the precision of the duration.

fpsfloat

  The number of frames per second. If duration is not given, the duration for each frame is set to 1/fps. Default 10.

palettesizeint

  The number of colors to quantize the image to. Is rounded to the nearest power of two. Default 256.

subrectanglesbool

  If True, will try and optimize the GIF by storing only the rectangular parts of each frame that change with respect to the previous. Default False.
