Folks,
Some of you know I have been engaged the past several months
writing a book about traditional graphics commands. It will
be ready shortly. As I have written the book, I have been
putting ideas from the book into practice in a series of
programs I've started to call Coyote Graphics:
http://www.idlcoyote.com/graphics_tips/coyote_graphics.html
There was one program left to finish, and that was
a resizeable graphics window to display these routines.
I spent the past two days completely re-writing the old
FSC_Window program from scratch. The old program allowed
a single command to be added to a resizeable graphics
window.
The new program is significantly more powerful. In fact,
an unlimited number of graphics "commands" can be added
to the window, commands can be deleted and replaced by
other commands, listed, and so on. Plus, you can have
multiple windows on the display, and you can interact
with the commands in any one of the windows.
It is even possible to display multiple plots in
the graphics window with a mechanism that will remind
you strongly of !P.Multi.
Contents of the graphics window can be sent directly to
a PostScript file (you will have to write your own
routines to be PostScript compatible, but all the
Coyote Graphics routines are already set up for this),
or you can save the graphics window in any of five
different raster file formats. If you have ImageMagick
installed on your computer, you will have the additional
option of creating these raster files from PostScript
files, which dramatically improves the quality of the
raster output, especially fonts.
You can read more about FSC_Window in this article:
http://www.idlcoyote.com/graphics_tips/fsc_window.html
This is really a very easy way to create graphical output
in a resizeable graphics window in IDL. You will be able
to run this program in any version of IDL, as far as I
know.
I think we have about 2-3 weeks to play with this program
before the final code freeze for the book. Please let me
know if you have any comments.
Cheers,
David
