\title "Using the Asterization Tool"
\next ""
\prev "mrx_hlp/mrx_aster"
\{ \ts b Imagemaster R/t\} 's Asterize tool allows you to create a wide range
of asterization effects. There are several preset asterizations or you can
create your own style of asterization. The preset asterizations are:
\{ \nw
\{ \ts b Vertical Glare\} : This will produce an asterization with two
vertically placed arms.
\{ \ts b Four Star\} : This asterization is a simple four armed \{ \ts i
star\} . This preset is the same as the \{ \ts i old \} asterize operation.
\{ \ts b Hex Lens\} : This is a six armed asterization that is rotated 30 degrees.
\{ \ts b Oct Lens\} : This is an eight armed asterization.
\{ \ts b Solar Flare\} : This will produce a one armed asterization that is
similar to a solar flare. The Arm Profile is a very random pattern.
\{ \ts b Even Glow\} : This will produce a one armed asterization with 50%
center asterization, and a flat line Arm Profile.
\{ \ts b Sparkle\} : This preset will produce an asterization that is similar
to the sparkle of a gem. There are twenty arms and a slight rotation.
\{ \ts b Flash\} : This will produce an asterization similar to a camera
flash. There are ten arms and a slight rotation of the asterization.
\}
The \{ \ts b Arm Profile \} graph allows you to alter the length of the arms
in the asterization. The length can vary over the total width of each arm.
The arm is altered from left to right with the bottom of the graph being a
zero arm length, and the top of the graph being an arm length that is 100% of
the selected area. The graph can be altered by holding down the left mouse
button while on the graph. You can then \{ \ts i draw \} on the graph to
alter the arm to suit your needs.
There is also a control to make the arms symmetrically reflective. If \{ \ts
b Reflective \} is selected, changes to the graph will be symmetrical about
the center of the arm.
The \{ \ts b Taper \} option allows you to specify a tapered or non-tapered
end. If taper is selected, the arm will go to a single point. All of the
Arm Profile information will still be used in producing the tapered effect.
\{ \ts bu \tc 15 \nw \ce Asterize Example\}
To access the Asterize tool, you'll have to load an image to so that the \{
\ts bi Process \} panel becomes available. Once you have loaded the image
select \{ \ts bi Process\} , \{ \ts bi Special F/x\} , \{ \ts bi >> \}
(Second Page of Effects), and finally \{ \ts bi Asterize\} .
After pressing Asterize, and selecting the area to be asterized, the
asterization panel controls will be available. At this time you can select
any of the presets or alter the graph to your specifications. For this
example select the \{ \ts bi Four Star \} preset. The graph should look like
this:
\{
\ra \image "Clips/astergraph.pic" c
\flushimage
\}
This will alter the controls to produce an asterization with four arms, and
an Arm Profile that increases along a curve to the center and decreases along
the same curve to the end of the arm. You should also note that both \{ \ts
b Taper \} and \{ \ts b Reflective \} are selected. Now, place the pointer
on the graph near the center position and \{ \ts i pull \} the graph down
about half way to the bottom. Notice that any changes are reflected on the
other half of the graph. Adjust the graph until the curve occurs for only
the first quarter and last quarter of the arm width. The \{ \ts i middle \}
quarters should be at the very bottom of the graph. The graph should look
something like this:
\{
\ra \image "Clips/altgraph.pic" c
\flushimage
\}
After obtaining this graph select \{ \ts b Done\}
. The asterization produced will have arms that are about one quarter the
total size of the selected area, and each arm will have what looks like two
seperate arms that are parallel. The asterization should look something like
this:
\{
\ra \image "Clips/aster.pic" c
\flushimage
\}
If you were to turn off the \{ \ts bi Taper \} button, the asterization would
then look something like this:
\{
\ra \image "Clips/notaper.pic" c
\flushimage
\}
It is important to note that you can also alter the color, saturation width,
rotation, and the number of arms in the asterization. After altering the
asterization to your specifications you can save the settings for later use.
As you can see, the Asterization tool has almost limitless possibilities for
creating and using custom asterizations.
