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.
