The user may define up to four "views", or sub-windows, to animate simultaneously. e.g., View 1 could be rainfall, View 2 flooded areas, View 3 damage to bridges or levees, View 4 other economic damage, all animated as a time series. There is an arbitrary limit of 400 files per view (400 animation frames), but the practical limit may be less depending on the window size and amount of available RAM.
The environment variable XGANIM_SIZE is checked for a value to use as the dimension, in pixels, of the longest dimension of the animation window. If XGANIM_SIZE is not set, the animation size defaults to the rows & columns in the current GRASS region, scaling if necessary to a default minimum size of 600 and maximum of 900. The resolution of the current GRASS region is maintained, independent of window size. Resizing the window after the program is running will have no effect on the animation size.
UNIX - style wild cards may be used with the command line version in place of a raster file name, but it must be quoted.
If the number of files differs for each view, the view with the fewest files will determine the number of frames in the animation.
export XGANIM_SIZE=800 xganim view1="rain[1-9]","rain1[0-2]" view2="temp*"
export XGANIM_SIZE=1000 xganim view1=rast[0-9],rast[1-9][0-9]
