| Warp applet |
 |
|
This applet can warp/spiralise any GIF
or JPG image. The only requirement is that this image
must be sized equally to one of the powers of 2 (64x64
pixel, or 32x64, 128x128, ...). Changing parameter values
allows you to simulate a "breathing image" effect. This
applet is fully parametrised, so you can generate all
kinds of warp effects.
[For more technical
information about the available parameters, click
here.]
Most parameters are self-explanatory
and you can always see brief description of each parameter
by moving the mouse pointer over the
wizard.

 |
First, set an image to apply this effect and
enter the applet size (Width, Height) according
to the resolution value. "Resolution"
value. "Resolution" is a zooming
parameter. For instance, the value 2 gives twice
as large an applet size as the screen size, while
the value 1 changes nothing. Then you decide if
textscroll function is enabled by checking "Enable
textscroll" box.
|
|
We have provided three kinds
of warp effect, which can be selected by "Mode"
parameter.
The deform effect comprises two different effects:
spiralisation and breathing.
|
 |
Spiralisation is controlled
by the initial value and increase factor per millisecond;
Start [-10000, 10000] and Add [0,
250]. The total spiralisation value can be restricted
by setting the Min and Max values.
These should be within the rage of [-10000, 10000]. |
 |
In the very similar way, you can configure
breathing parameters:
Start, Min, & Max:
[-10000, 10000]
Add: [0, 250]
|
|
|
To deactivate each of the effects, place 0
at a respective Add parameter.
|
|

|
We have only discussed about the warp
specific parameters. For generic parameters, please
read wizard section.
Proceed to the
textscroll menu if you have checked the textscroll
box; otherwise go to the expert
menu.
