Graphic filter toolbar
After selecting a graphic and the Picture toolbar (Figure 137) has opened, click on the Filter icon
to open the Graphic Filter toolbar (Figure 140). Draw offers eleven filter effects. Filters work
on the current view of a graphic and they can be combined. Filters always apply to the entire
graphic; it is not possible to use filters to edit only a part of the object.

Note
If your graphic is linked, any graphic filters used are only applied to the current view.
The original graphic is not changed. When you close the drawing, any filtering
applied is lost. To keep a copy of the filtered graphic, export the graphic to create a
copy with all the filters applied (File > Export).
If your graphic is embedded, all graphic filters are applied directly on the embedded
graphic and cannot be undone in a subsequent session. After you save and close
the drawing, the graphic filter effects become permanent. If you do not want to retain
a graphic filter, you must use Edit > Undo to cancel the filter effect before saving the
file.
Invert graphic filter
Clicking on the Invert icon inverts or reverses the color values of a color image (similar to a
color negative), or the brightness values of a grayscale image. Apply the filter again to revert to the
original graphic (Figure 141).
