Demonstration of TpX import capabilities

Alexander Tsyplakov

January 31, 2006

Abstract

TpX (http://tpx.sourceforge.net/) is a lightweight, easy-to-use graph-ical editor for Windows platform for creation of drawings and inclusionthem into LATEX files in publication-ready form. It can also be used as astand-alone editor for vector graphics.

Under Windows most reasonable programs, which produce graphs, caneither export them as EMF files, or copy to clipboard as EMF. TpX can im-port Enhanced Metafiles (EMF) though not 100% correctly. Old-style Win-dows Metafiles (WMF) are imported by converting them to EMF. TpX canalso import simple SVG pictures.

This document demonstrates TpX import capabilities. Examples are ex-ported from many well-known as well as less known Windows programs.

1 Forewarning

The aim of this document is to show the potential of using TpX for importingWindows metafile and SVG graphics into LATEX documents and to reveal pos-sible complications related to using TpX for this purpose. The author has nointension to evaluate the programs which were used to create the pictures. Pos-sibly, some problems are due to misuse of those programs. Also, some problemsmight have been fixed in recent versions.

2 Some remarks

X TpX can add TEX formulas to graphs (see 3D plot from Gnuplot below).X It is possible to edit imported images and correct their deficiencies. For

example, TpX can help to shift misplaced text labels.X Common problem with metafile images exported from Windows pro-

grams is low resolution used to represent coordinates inside metafile. Thiscauses bad quality of some metafile images.

X Some programs use the same line width (e.g. 1 pixel) for all lines inmetafile, though in other export formats (for example, PostScript) lines havedifferent widths.

X For some programs metafile is not the preferred export format and canbe of lower quality than, for example, PostScript images.

X Some features of the original metafile image are not preserved, like bitmaps,font styles.

X It is possible to mimic the fonts of the original image to some extent, butit needs manual editing. In most cases fonts from LATEX are good enough anyway.

X As SVG format is very rich TpX can understand only some basic subset ofit.
