GRI_MERGE(1)						      General Commands Manual						      GRI_MERGE(1)

NAME
gri_merge - merge multiple Gri output files into a single PostScript file. USAGE (style 1): gri_merge [OPTIONS] CxR a.ps b.ps ... > merged_file.ps Merges the files onto one page, in 'C' columns and 'R' rows. The CxR files are given in the order of words on a page. The page is pre- sumed to be 8.5x11in in size, as are all the input files, and the input files are sized to fit, and kept in natural scale. USAGE (style 2): gri_merge [OPTIONS] xcm ycm enlarge a.ps [b.ps ...] > merged_file.ps Where `enlarge' is a scale factor applied after offsetting `xcm' to the right and `ycm' upward. EXAMPLE (style 2): The following gri_merge 2 12 .5 a.ps 12 12 .5 b.ps 2 2 .5 c.ps 12 2 .5 d.ps > all.ps produces 4 panels from gri plots done using margins and sizes as specified in the following lines in a gri commandfile set x margin 2 set x size 15 set y margin 2 set y size 15 The OPTIONS, available if your 'perl' has 'getopts' library, are: -u graylevel -- set graylevel for underlay beneath panels, by default 0.75. Values range from 0 (black) to 1 (white), although a value of precisely 1 means do NOT draw underlay. -b graylevel -- Set value for background under individual panels, again 0 for black to 1 for white, with 1 meaning no drawing. -h -- Print this help message and quit.
