gri_merge
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.
