The Relief filter calculates the edges in relief of the picture and produces

a picture as if illuminated by a light source, the position of the

illuminating light being variable and producing shadows that differ in

direction and magnitude.

Mosaic takes groups of pixels and converts them into a single color

rectangular tile. The whole picture appears to be a mosaic. The center and

right pictures below had an element resolution of 5 pixels. The picture on

the right also had the Enhance edges option selected; with the greater

contrast at the edges, it appears to be a little sharper.

Caution

If your picture is linked, filters are applied only to the current view. The

stored picture is not changed. When you close the document, all

filtering is lost. You should ensure that you export the picture to create

a copy with all the filters applied (File > Export).

If you have embedded the graphic in the document, all filters are

applied directly on the embedded graphic and cannot be undone in a

subsequent session. If you do not want to retain a filter, you must use

Edit > Undo to return to an earlier state of editing. After you save and

close the document, the filter effects are permanent.

Changing colors using the eyedropper

Use the eyedropper to change one color in a picture for another or set the color as

transparent. The tool always works on the entire picture; you cannot select only a

region for editing.

The changes are carried out on the graphic itself and therefore require it to be

embedded. Attempts to use the eyedropper tool on a linked graphic result in the

following message: This graphic is linked to a document. Do you want to unlink the

graphic is order to edit it?

The tool can be used on all raster graphic formats and with many—but not all—

Metafile formats.

Note

In OpenOffice.org 3.4, this feature is called the Color Replacer.
