Raster Image - Drop Shadow

The Drop Shadow operation is an operation plug-in, which works with raster images and adds a shadow of given color, size, position and density to an image.

Outer shadow was added to the red circle.

Shadow is the silhouette of an image (cropped by an optional image mask) that has been blurred, its transparency was adjusted and the result was optionally moved by given distance from the original position. Floating point numbers may be used to specify the blur radius and the offsets.

The Shadow position parameter (added in version 2011.1) has major influence on the behavior of the effect:

  • If it is set to Shadow only, the original image is deleted and only the shadow remains.
  • The Outer shadow is the most common behavior - the shadow is placed under the actual image.
  • The Inner shadow inverts the effect. The shadow is placed over the image, but the shadow source is the exterior.

The shadow operation can be instructed to change the size of the image to ensure that there is enough space for the shadow. This is important for completely opaque images, because the underlying shadow would not be visible otherwise.

It is possible to select the shadow color. If other than black color is used, the shadow effect becomes less a shadow and resembles a glow effect.

i don't know if its a bug but when you put this shadow effect on a cursor when you drag files it shows a big circle-like shadow, can you help me please?

that happens when you set the created/edited cursors as your cursor scheme

Windows 10. Real World does not appear to handle drop shadows any loger. No longer, is there a "resize image" checkbox. The shadow is not visible. Additioanlly, no longer, is there a way to see 'before' and 'affected' image in the same preview window. Why change all of this? It worked so well before but is now broken. Help!

Windows version should not affect the behavior at all. Are you by chance trying to add shadow to a vector layer?
