Description [src]
Optional arguments:
dither: %gdouble, quantisation dithering leveleffort: %gint, quantisation CPU effortbitdepth: %gint, number of bits per pixelinterframe_maxerror: %gdouble, maximum inter-frame error for transparencyreoptimise: %gboolean, reoptimise colour palettesinterlace: %gboolean, write an interlaced (progressive) GIFinterpalette_maxerror: %gdouble, maximum inter-palette error for palette reusage
Write to a file in GIF format.
Use dither to set the degree of Floyd-Steinberg dithering
and effort to control the CPU effort (1 is the fastest,
10 is the slowest, 7 is the default).
Use bitdepth (from 1 to 8, default 8) to control the number
of colours in the palette. The first entry in the palette is
always reserved for transparency. For example, a bitdepth of
4 will allow the output to contain up to 15 colours.
Use interframe_maxerror to set the threshold below which pixels are
considered equal.
Pixels which don’t change from frame to frame can be made transparent,
improving the compression rate. Default 0.
If reoptimise is TRUE, new palettes will be generated. Use
interpalette_maxerror to set the threshold below which one of the previously
generated palettes will be reused.
If interlace is TRUE, the GIF file will be interlaced (progressive GIF).
These files may be better for display over a slow network
conection, but need more memory to encode.
