# gri\_merge(1)

merge multiple Gri output files into a single PostScript file.

## 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 presumed 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.
