If you have used previous versions of Flash you will find the Preview button in the Trace Bitmap dialog box a welcome addition to Flash CS5. 4. Click ok to apply the change and close the dialog box. 5. Now you ll see what happens when you use even closer tolerances. Select the image on the right of the stage and open the Trace Bitmap dialog box. Specify these values Color threshold 5 Minimum area 2 Corner threshold Many corners Curve fit Pixels 6. Click the Preview button. The progress bar will take a bit longer this time and when it finishes the difference between the original image and the vector image is not readily evident.
