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 inclusion them into LATEX files in publication-ready form. It can also be used as a stand-alone editor for vector graphics. Under Windows most reasonable programs, which produce graphs, can either 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 can also 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 importing Windows metafile and SVG graphics into LATEX documents and to reveal pos- sible complications related to using TpX for this purpose. The author has no intension to evaluate the programs which were used to create the pictures. Pos- sibly, some problems are due to misuse of those programs. Also, some problems might have been fixed in recent versions. 4
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. This causes bad quality of some metafile images. X Some programs use the same line width (e.g. 1 pixel) for all lines in metafile, though in other export formats (for example, PostScript) lines have different widths. X For some programs metafile is not the preferred export format and can be 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, but it 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 of it. 5

Comment: The source of image is http://www.freeclipart.nu site. EPS is not the original one, created with Adobe Illustrator. It was converted from EPS to EPS using Ghostscript epswrite device. Imported to TpX using pstoedit(http: //www.pstoedit.net/pstoedit). Free version of pstoedit somewhat distorted image by converting Bezier curves to polygons. 19
