rglactions {fsbrain}

Create rglactions list, suitable to be passed as parameter to vis functions.

Description

Create rglactions list, suitable to be passed as parameter to vis functions.

Usage

rglactions()

Value

named list, an example 'rlgactions' instance that will save a screenshot of the plot produced by the vis function in the current working directory (see getwd), under the name 'fsbrain_out.png'.

Note

List of all available rglactions: (1) 'snapshot_png=filepath' takes a screenshot in PNG format and saves it in at 'filepath'. (2) 'trans_fun=function' uses the transformation function trans_fun to the data before mapping data values to colors and plotting. Popular transformation functions are limit_fun, limit_fun_na, and clip_fun. (3) 'text=arglist' calls text3d with the given args after plotting. (4) ‘snapshot_vec=filepath' takes a screenshot in vector format and saves it in at 'filepath'. You also need to set the format via 'snapshot_vec_format', valid entries are one of "ps", "eps", "tex", "pdf", "svg", "pgf" (default is ’eps'). This is experimental and may take a while.

Examples

   rgla_screenie = list('snapshot_png'='fsbain_out.png');
   rgla_screenie = rglactions();   # same as above
   rgla_vec_scr = list('snapshot_vec'="~/fsbrain.pdf",
     "snapshot_vec_format"="pdf");
   rgla_clamp = list('trans_fun'=clip.data); # old style
   rgla_clamp = list('trans_fun'=clip_fun(0.05, 0.95)); # new style
   rgla_clamp = list('trans_fun'=clip_fun());            # equivalent.
   rgla_limit = list('trans_fun'=limit_fun(2,5));
   rgla_ls = list('trans_fun'=limit_fun_na(2,5), 'snapshot_png'='~/fig1.png');
