module Tioga

# = PDF Fonts
#
# Text is normally sent to TeX, allowing you to use any font that can be accessed from your TeX documents.  
# However, in certain special cases you may need to use text in a "graphical" manner and have it processed directly in the 
# PDF output.  In that case, tioga needs to have metric information for the font (in the form of an "afm" file), and any 
# output device needs to have access to the font definitions.  Providing a general solution to this is still a bit messy, and for the 
# expected use in tioga, I decided that it wasn't worth it.  All PDF devices are guaranteed to have the 14 standard Adobe 
# fonts, so they are easy to provide -- and that's what I've done.
#
# Here are the abc's of the PDF fonts, clockwise from the top: Times_Roman, Times_Italic, Times_Bold, Times_BoldItalic, Helvetica, Helvetica_Oblique, Helvetica_Bold, Helvetica_BoldOblique, Courier, Courier_Oblique, Courier_Bold, Courier_BoldOblique, Symbol, and ZapfDingbats.

#
# = Markers
#
# Any character from any of the PDF fonts can be used as a marker.
# The predefined marker names are provided as a convenience, not as an exhaustive list.   Markers are specified by 
# either a font number and character code (for filled characters), or by a font number, character code, and line 
# width (for stroked characters).  In the following figure many of the markers appear in both a filled form, such 
# as 'Arrow', and a stroked form, such as 'ArrowOpen'.   The color of filled markers is determined by the current 
# setting of fill_color, and, similarly, stroke_color determines the color of stroked markers.

#
# Here is the full set of options from the ZapfDingbats font.  If you would like to use the jet plane as a marker,
# just write [ ZapfDingbats, 40 ] where you would have used one of the predefined marker names.
