Bevel - to add a slightly raised or sunken effect to the thumbnail in question. The width of bevel is variable as are the colours for both the top+left and base+right shading. |
Motion Blur - A variable number of fading lines drifting from the thumbnail gives the effect of a slight motion blur. Variables are used for the number of lines and the background colour. |
Merge / Overlay - allows a variable opacity image to be drawn over the thumbnail at any defined location. In addition, a colour can be set as transparent to allow the thumbnail to show through. |
Greyscale - converting the image to a greyscaled (black and white) representation of itself. The strength of red-green-blue channels can be set through passed variables. |
Frame - a quite simple single colour picture frame is drawn around the thumbnail and given the effect of being raised by a lighter and darker edge. With variables for light colour, dark colour and frame width. |
Round Edges - used to take the harshness away from simple rectangular thumbnails, also offers a slight anti-alias on the corners. Variables are used for the edge radius, the background colour and the anti-alias width. |
Drop Shadow - as the name implies, a shadow effect fades from two edges of the thumbnail. Will probably do a bit more work on this effect as I'm not overly happy with it yet. |
Ellipse - Carving away the outer borders into the shape of an ellipse can work especially well on sites which use a more rounded design. Currently used one variable for background colour, though I might add one for anti-alias strength. |
| It is possible to stack transformations on top of each other to create even more styled thumbnails, as the images below show. |
Greyscale, Ellipse, Bevel and RoundEdges can be used together in sequence to create thumbnails with the effect shown to the left. |
Frame, MotionBlur and Merge can be used together to quite good effect as shown to the left.
Many other effects are possible. |
