5.3 How TeXdraw merges graphics and text
========================================

TeXdraw creates a box which is the same size as the graphic.  The
printer driver will place the PostScript graphic into this space.  Any
TeX text generated by the TeXdraw commands will be superimposed on this
graphic.

   The LaTeX2e front-end for TeXdraw is enabled by including the
'texdraw' package.  The 'texdraw' package automatically invokes the
standard 'graphics' package distributed with LaTeX2e.  The 'graphics'
package has support for a number of different printer drivers, including
a number for PostScript printers.  Any options to the 'texdraw' package
are passed on to the 'graphics' package.  Such an option can be used to
select a driver other than the default one.

   Within the 'graphics' package, the driver option is used to select
definitions for the low-level macros which generate the '\special'
commands needed to request insertion of a graphics file and to rotate
text.(1)  TeXdraw uses the user-level macros defined by the 'graphics'
package (Note: PostScript printer drivers).  When not used with the
LaTeX2e front-end, TeXdraw defines versions of these macros that are
suitable for use with the 'dvips' printer driver.
