Example for the “Drop Shadow” filter
This filter adds a drop-shadow to the current selection or to the image
if there's no active selection. Optional the filter resizes the image if
that's necessary for displaying the shadow.
You may choose the color, position, and size of the shadow.
Please note that the filter does not add a background layer to make the
shadow visible. The shadow's background is transparent. The white
background in the above example has not been created by the filter,
instead it has been added later to let you see the shadow.
Activate the filter
You can find this filter in the image menu menu through
→ → .
“Drop Shadow” filter options
Offset X; Offset Y
The layer containing the drop shadow will be moved horizontally
by X pixels, vertically by Y pixels. So, X and Y offset
determine where the shadow will be placed in relation to the
image. High values make the imaginary source of light look like
it's far away in horizontal or vertical direction, and low
values will make it look closer to the image.
The offsets may be negative, leading to a shadow on the left of
the selection if offset X < 0, or above the selection if offset
Y < 0.
If there's no active selection, you must have Allow
resizing enabled to see any effect.
After creating the shadow, a Gaussian blur with the specified
radius is applied to the shadow layer, resulting in the realistic
appearance of the drop shadow. It may be necessary to enable
Allow resizing, since blurring extends the
The shadow may have any color. Just click on the button, and
select a color when the color selector pops up.
“Drop Shadow” color example
The shadow's opacity is just the opacity of the new layer
containing the shadow (see Section 1.1, “Layer Properties”). It defaults to 80%, but you may select any other value from 0
(full transparency) to 100 (full opacity) here. After applying the
filter to an image you can change the opacity in the layers dialog.
If enabled, the filter will resize the image if that is needed to
make place for the shadow. The new size depends on the size of the
selection, the blur radius, and the shadow offsets.
