SYNOPSIS
SEISMIC UNIX NOTES PSMERGE - MERGE PostScript files
psmerge in= [optional parameters] >postscriptfile
Required Parameters:
in= postscript file to merge
Optional Parameters:
origin=0.0,0.0 x,y origin in inches
scale=1.0,1.0 x,y scale factors
rotate=0.0 rotation angle in degrees
translate=0.0,0.0 x,y translation in inches
Notes:
More than one set of in, origin, scale, rotate, and translate
parameters may be specified. Output x and y coordinates are
determined by:
x = tx + (x-ox)*sx*cos(d) - (y-oy)*sy*sin(d)
y = ty + (x-ox)*sx*sin(d) + (y-oy)*sy*cos(d)
where tx,ty are translate coordinates, ox,oy are origin coordinates,
sx,sy are scale factors, and d is the rotation angle. Note that the
order of operations is shift (origin), scale, rotate, and translate.
If the number of occurrences of a given parameter is less than the number
of input files, then the last occurrence of that parameter will apply to
all subsequent files. User's notes (Juan Lorenzo) untested
