Bitmap Editor
1. The Bitmap Editor gives you the ability for work on your images and cleans them up before you
bring them back into Gravostyle to Vectoize. Save your work regularly if you are working on a
long or complex image, or if you have to stop working before you have finished. If the image has
already been saved, the Bitmap editor saves the modifications in the .bmp file of the same name.
The Bitmap Editor is one of the two places in Gravostyle that you can save a Bitmap. With a
Bitmap selected on the Main screen, click on the Bitmap Editor icon
