![]() If you image has a lot of colors (as a photograph or a scanned image might) you can tell Autotrace to reduce the palette to as few colors as you want. Color count - When set to zero, Autotrace will trace out separate regions for every color that it finds.Background Color - If the image you are tracing has a background color, you can select it here and Autotrace will ignore it otherwise the tracing algorithm will draw a polygon filled with the background color.All are available discuss related options together. Here is a rundown of the available options and the effects they have on tracing. ![]() Frontline lets you tweak settings and retrace your image as many times as necessary before you save the result, which is useful because there is no “best” configuration every image is different and requires tweaking. The main Frontline window displays a file selection box at the top labeled Image Trace and Close buttons at the bottom and a field of 16 checkboxes and sliders in between that control your options. As an example, I have chosen a sketch of a sawfish cartoon, originally drawn on lined notebook paper then scanned. To see how it works, install and launch Frontline and pick a bitmap or PNG file to work with. You can run Frontline as a standalone application or call it from within another image editor like the GIMP. For Linux users, a pair of programs called Autotrace and Frontline are just what the doctor ordered, finding the edges and curves in the raster image, tracing the result, and generating a vector image that you can work with in a program like Inkscape or Sodipodi.Īutotrace is a command-line program written by Martin Weber Frontline is its GTK front-end by Masatake Yamato. When you need to create a vector-based image out of a raster-based image, you have two choices: trace it out yourself (via mouse or graphics tablet), or use a specialized program to automatically trace and convert it for you. ![]() ![]() Graphic designers prefer to work with vector-drawing applications because they can manipulate the shapes of the designs themselves, rather than the pixels that form the design in a raster image. ![]()
