The Script-Fu Layer Effects
Adobe has special effects in Photoshop, the so-called layer styles or layer
effects. This collection includes effects like Drop Shadow, Bevel and Emboss,
Outer and Inner Glow, and so on.
Jon Stipe developed an equivalent script-fu for GIMP called layerfx.scm .
You can download it from You can also
find it on the DVD in the folder GIMP Script-Fus . Installing script-fus and filters
is described in section 1.5.2. After the installation in GIMP, you must select
Filter > Script Fu > Refresh Scripts . A new entry, Script-Fu, then appears in the
menu bar. Under Layer Effects, you can find a dozen different layer styles with
a multitude of settings. Unfortunately there isn't a preview function. You will
have to experiment with the various settings and choices. But it is worthwhile.
3.8 Creating Your Own Image Frames
and Vignettes
You've now learned quite a bit about filters and effects. Now let's look at the
possibilities available for designing an image frame. It could be a single-color
frame or a frame filled with patterns, such as a wood texture. Or you might
decide that your image will look more impressive in a frameless glass picture
holder. You could also create a vignette in the form of an oval overlay—or
another shape such as a keyhole—as was often done with old black-and-
white photos. Any shape created with a select tool can be transformed into
a frame. Of course, you can find effects to individualize your new frame in the
Filter menu.
3.8.1 Single-Color Image Frames
Single-color image frames are the easiest to create. In the dialog box of the
Script-Fu Add Border (Filters > Decor > Add Border) you can choose the settings
for the width and the color of the frame. Clicking OK , the border is produced
automatically. All you have to do ahead of time is enlarge the canvas, that is, if
you want to frame the image so that it appears to be on a mount. Or you can
place the frame directly on the image.
