Section 46.7 Images Described in Source
As we discussed in Section 5.8 , there are many advantages to describing images directly in the source of your PreTeXt document. However, these must be processed with various “helper” programs such as
asy
,pdflatex
, and sage
.The issue with this is that XSL is not a general purpose programming language, and so in particular, cannot call the “helper” programs. The general strategy is to use XSL to identify and isolate the parts of a document that lie in the elements designed for graphics languages. A Python script, the
pretext
script, employs these XSL stylesheets and then feeds each image file to the appropriate helper program.This script has a variety of options, so we document it fully in Chapter 47 .
