AutoTrace  AutoTrace - converts bitmap to vector graphics IntroductionInstallation Features Screenshots Documentation Download Bugs Contributions Contributors History Links Contact   News AutoTrace now also available online. [01/28/04] Delineate 0.5 has been released. [12/28/03] Delineate 0.4 has been released. [11/05/03] Delineate 0.2 has been released. Delineate is another GUI front end for autotrace written in Java. [9/13/03] First public release of frontline, a Gnome/Gtk+ based GUI front end for autotrace. With frontline you are able to set trace options via GUI and preview trace results quickly. [11/12/02] New release 0.31.1 available for download. Fixed compile time error, centerline tracing , dr2d and dxf output [11/09/02] Grrr: There is a program that is comparable to AutoTrace: ScanFont 3.0. Please help to make AutoTrace better than this program! A demo for Windows could be downloaded here. [10/08/99] Call for Help: AutoTrace needs more import/export filters, porting to other platforms, ... Who wants to help developing these parts? [09/23/99] AutoTrace mailing-list started. Look at Yahoo! Groups for subscription or send an email to autotrace-subscribe@yahoogroups.com and subscribe automatically. [09/21/99] Introduction Welcome to AutoTrace - a program for converting bitmap to vector graphics. The aim of the AutoTrace project is the development of a freely available application with a functionality similar to CorelTrace or Adobe Streamline. I hope that it will become better than all commercially available programs. In some aspects it is already better. AutoTrace is free software. AutoTrace is distributed under the term of GNU GPL. Installation AutoTrace currently comes in source code and some binaries - you have to compile the package for other platforms yourself. After downloading the archive, unpack the distribution and use make to compile it. Features Here is a short description of currently supported formats: Inputformats BMP, TGA, PNM, PPM, PGM, PBM and those supported by ImageMagick. Exportformat Postscript, svg, xfig, swf, pstoedit, emf, dxf, cgm, mif, p2e and sk Screenshots Some screenshots are available here: Simple example and it's output Comparison of tracing a small m with AutoTrace and other programs Comparison of tracing small circles with AutoTrace and Scanfont Comparison of tracing letters with AutoTrace and Scanfont Documentation Currently there is no documentation other than the online help.

Contributions I invite you to participate in the AutoTrace project. First, if you plan to contribute some code, please contact me in order to avoid duplicate work. Core: - Speed up - Improve tracing quality - Bugs?! - Recognition of Circle and Ellipse pieces. - Addition of code to recognize lines, splines and circles even if there is a lot of noise - Currently pictures have to fit completely into memory - New algorithm to work best with antialiased pictures - 3D recognition - Better list management, that means the current generation of lists is time consuming and fragmentates the heap. - Outlines are traced two times that means that it could be faster and if we trace and fit every outline only once we will not have the problems with unwanted gaps anymore. - Better thinning algorithm like CAT (Chordal Axis Transformation) Input: - Mirgrate new plug-in interface with using glib(0.32) - Support of image libraries as freeimage, gdk-pixbuf or paintlib(0.32) Output: - Mirgrate new plug-in interface with using glib(0.32) - New export formats like wmf, cdr, cmx, compressed pdf, compressed svg and dxf with splines... Library and its clients: - Graphical userinterface -- For gnome/gtk, frontline is under developing. (See http://autotrace.sourceforge.net/frontline. It works well with sodipodi, a drawing editor.) -- For KDE/Qt? ...
