Image Alchemy is used to transcribe image files from one type to another. We use it mostly to switch Postscript (.ps or .eps) to Hewlett Packard RTL (.rtl) to print on the hpplot345 printer. It's a wacky language. Below is the script normally used for that procedure:
alchemy --r7 (input_file.eps) -Zm2 -Zi10i 18i -Zo10i 18i -Z+
--r7 sets the output to .rtl
next comes the input file name
-Zm2 sets the output to a color file
-ZiXi Yi describes the physical dimensions of the input image in inches
-ZoXi Yi describes the physical dimensions of the output image in inches
-Z+ preserves the output aspect ratio
and the output looks like this:
Image Alchemy PS (v1.7.7) - Copyright (c) 1990-94, Handmade Software, Inc.
Reading PostScript file input_file.eps
Writing HP RTL file output_file.rtl (output type 7)
Interpreting PostScript file........................................
Switching to 1 bit CMYK output
Saving image.......................................
You can also use Alchmey to convert the .eps output from ArcPress into a .tif file for inclusion in a poster or slide show, as in this example:
alchemy (input_file.eps) -t -24 -D 300 300 -Zi 16i 12i -Zo 16i 12i -Zm2
As it stands now, alchemy routes the temporary /data/playpen/pscratch/USER.
That's why it doesn't go very fast if the network is down. So one potential
is make your own script and put it in the directory you're using. Change the
script so that the directory is something local.
