There are many packages to do pictures in (La)TeX itself (rather than
importing graphics created externally), ranging from simple use of
LaTeX picture
environment, through enhancements like
epic, to
sophisticated (but slow) drawing with PiCTeX. Depending on your type
of drawing, and setup, here are a few systems you may consider:
picture
environment. It therefore suffers only from the rather
eccentric drawing language of the environment, and is a far more
useful tool than the environment itself has ever been.
\
special
commands. The \
special
s are
by default specific to dvips, but VTeX (both in its
commercial and in its free versions) understands them. PDFTeX
users may use pdftricks, which (like
epstopdf - see
PDFLaTeX graphics) generates
PDF files on the fly from pstricks commands. The
documentation is good (you may browse it via the
pstricks page
on the TUG web site), and another extremely valuable
web site lists supporting
packages (for various specialised drawing operations) and many
enticing examples. There is also a mailing list
(pstricks@tug.org) which you may
join, or you may
just
browse the list archives.
