Oleg provided a mechanism to save viewmat images to PNG files, so I feel that the following should generate all the image files for this table. However, it does not; I just get a bunch of empty white images.

Debugging indicates that it is probably a repaint/selected window issue. I do not know how to fix it.

load 'viewmat media/platimg debug'
coinsert 'jgl2'

PP      =:  1 : 'viewmat@:(u [: | j./~@:i:)'
glqall  =:  (|. $ [:glqpixels 0 0&,)@glqwh
glwh    =:  3 : 'wd''pmovex '',(+0 0,y-glqwh_jgl2_@$@#)&.".wd''qformx'''

ppp     =:  dyad define           NB. Pretty picture print

Well this steps into the uncharted treacherous territory of sync programmatic execution and async GUI. So I guess to do it like that, the use of timer might help. But that's an overkill.

I recommend using something that is proven and supported like the animate addon. You can designate each picture as a step in the animation. And all will be saved nicely in a series of files. I guess you could take it further by making code that will convert your boxed list of picture verbs into a script for animate automatically. Or have just one new animate script that will accept a list of picture verbs in some form and derive number of steps, etc. Maybe an Options dialog.
