Figure 159: Convert to Polygon dialog
Polygon Conversion
Converts a selected graphic to a collection of polygons filled with color. The graphic also becomes
a vector graphic and can be resized with no loss of image quality or distortion of any text. After
conversion, you can break the graphic into groups of polygons and then split these groups into
individual polygons. Breaking and splitting allows you to edit or delete individual colors within the
graphic.
Converting
To convert a graphic to a polygon:
1) Select the graphic in your drawing.
2) Go to Modify > Convert > To Polygon, on the main menu bar, or right-click on the graphic
and select Convert > To Polygon to open the Convert to Polygon dialog (Figure 159).
3) Select the Number of colors and Point reduction to be used in the conversion.
4) To prevent any blank areas appearing in your graphic, select Fill holes and the number of
pixels to use for the Tile size.
5) Click Preview to check how your converted graphic will look.
6) Make any necessary changes to the settings and check the preview again.
7) If you are satisfied, click OK to convert your graphic to a polygon.
