Tracing Bitmaps in Flash

With Flash you easily convert your imported graphics into vector graphics. Once converted, you can manipulate the vector graphic from within Flash. For example, remove colors, add colors, distort shapes, etc.  This has been extremely helpful while working on a Ben Franklin course I am currently developing. I have been importing graphics of historical illustrations and artifacts (none with copyrights). In order to keep the same “cartoon” feel of the Minutebio courses, I used this method. Giving the graphics a more uniform, cartoon look, plus vector graphics scale up better.


Here’s how it works:


Highlight the imported graphic. In the menu, use Modify>Bitmap>Trace Bitmap.



The Trace Bitmap dialog box will appear. Color threshold and other parameters can be adjusted and previewed. Click OK and it becomes a vector graphic.

It can now be easily manipulated. In the example below, background colors have been removed, the shape of the arm has been changed and numerous colors have been added.


This example is from the Ben Franklin wallpaper and will also be used in the MinuteBio m-learning course (available soon).
