“Engrave” applied

This filter produces an engraving effect: the image is turned black and white and some horizontal lines of varying height are drawn depending on the value of underlying pixels. The resulting effect reminds of engravings found in coins and old book illustrations.

| Note
The “Engrave” filter operates only on floating selections and layers with an alpha channel. If the active layer does not have an alpha channel please add it first.

#### 4.5.2. Activating the filter

This filter is found in the image window menu under Filters → Distorts → Engrave.
