Conversion

Convert to a contoured image

Select the picture so you see the green handles. From the context menu or from the

Modify menu choose Convert > to Contour. This command creates from the

original image a polygon or group of polygons, with four corner points and the image

set as a background graphic. In this state you are not able to further edit the graphic.

All your modifications must be completed before this point.

The polygon is in fact a vector graphic but the picture remains as a bitmap image.

Using a polygon offers possibilities for further change; for example, you can modify

the shape or define a transparency gradient.

Convert to a polygon

Select the picture so you see the green handles. From the context menu or from the

Modify menu, choose Convert > to Polygon. This command converts areas of the

same color into small filled polygons. The total image becomes a vector graphic and

can be resized with no loss of image quality or distortion of text. The resulting format

will be a Metafile.
