The Extrude Option
The Extrude option makes the cutout appear to pop out of the image by redrawing the cutout one layer on
top of another. Each layer in the stack is offset slightly from the one below so only the edges of the layer
are visible.
Editing the Layers
When you create a cutout using the Extrude option, two layers are created to produce the effect. There are
vertices at the centre of each layer for manipulating the layer. You can change the depth and direction of
the extrusion by moving either layer.
Changing the Colour of the Layers
Enable Use Colour to apply the current colour to the extrusion layers. The cutout image is used for the top
layer only. When Use Colour is enabled, use the Brush Opacity field to set the transparency of the extrusion
layers.
The Blend Options
The Blend options use the RGB values of the cutout and those of the result image. Select a blend option
from the Blend Mode box.
(a) Blend Mode box
Blend Pastes the cutout onto the result image.
Add Adds the RGB values of the corresponding pixels in the cutout and the result image. Values greater
than 255 are clipped.
Subtract Subtracts the RGB values of pixels in the image from those of the cutout. Values less than 0 are
clipped.
Black Pastes a black object in the shape of the cutout on the result image.
White Pastes a white object in the shape of the cutout on the result image.
Colour Pastes a coloured object in the shape of the cutout on the result image. The current colour is used
for the object.
NAdd Min Compares the brightness values of corresponding pixels in the cutout and the result image, and
uses the pixel with the smaller value in the tacked down cutout.
