The Coyote Library evolved from work David Fanning was doing teaching
IDL courses and answering IDL questions on the IDL newsgroup. It is
meant to be a well-documented library that demonstrates how to write
solid IDL/GDL programs that are easy to maintain and extend.
.
The main content of the library is the Coyote Graphics System (CGS),
a collection of Coyote Library programs that turn the traditional
GDL/IDL graphics commands (e.g., Plot, Contour, Surface, TV, etc.)
into modern programs.
.
The most important features of Coyote Graphics System are:
.
* The commands work identically on the display, in PostScript, and
in the Z-graphics buffer.
* The commands can be displayed automatically in resizable graphics
windows.
* The commands automatically create high quality PostScript, PDF,
and raster file output.
* CGS graphics visualizations can be saved and restore later, or
e-mailed to colleagues.
* The commands work identically in an indexed or decomposed color
environment.
* The commands can use colors by name (e.g., "red", "dodger blue").
* CGS commands are faster (often much faster) than the equivalent
IDL function graphics commands.
* Greek letters and other symbols can be directly embedded in Coyote
Graphics text.
* The commands fix the most annoying quirks (e.g., contour holes and
levels) in traditional IDL commands.
