Using fireworks "establish the control point method" to paint the colorful picture

In this tutorial you will learn how to use fireworks to "set up control points" to control "zoom Blur" and "radial blur", and to draw the following beautiful piece of work.

1. Establish the control point method

In fireworks, if you apply the zoom blur filter to an object, you will find that you cannot control the direction of zooming. As shown in Figure 1, the "zoom blur" is applied directly, and the effect is only scaled and blurred from the center of the graphic.

But to achieve the effect of Figure 2, that is, can control the "zoom blur" direction, it is necessary to use the original "Rockhward" set up the control point law.

2. How to establish a control point

First we know the principle of the "zoom blur" filter is to first determine the center point of the object, then "shrink" and "magnify" two fuzzy. In other words, you can change the center point of the object to control the direction of the zoom blur.

How do you change the center point of an object? That is, using a graph and the original "zoom Blur" of the Graphic "combination", so that the two-figure line of the midpoint is the new center point.

As shown in the figure, the white vector circle is equivalent to the control point where the center point can be controlled.

3. How to control the direction

When a handle is established and the control point and the original graphic are grouped, the zoom blur filter is applied (the filter's parameters are set to 80 in the following illustration to see the direction of the blur along both lines).

You can control the direction of the blur by using the Subselection tool to drag the handle.

Another issue to note is how to make the handle disappear: Use the Subselection tool to select the handle, and change the transparency to "1".

After learning to "establish the control point method", we begin to draw the example!

4. Instance Drawing

After learning to "establish the control point method", we begin to draw the example!

such as drawing a white rectangle as a handle, and then draw a gradient of the rectangle (260*40px) as a leaf, rotating a certain angle, the two together.

Apply the "radial blur" filter to the combination, with a quantity of 100 and a quality of 80.

5. Different effects

Here we use the same method to design different styles of lettuce.

Place the canvas on a 600*480 black background and then put on some glowing text for decoration.

6. Plate

In fact, the control point does not necessarily want it to disappear, the use of the radiation of the control points to simulate some of the ring decorative effect (reminds me of Rocher chocolate ...) )。 But you need to add a couple of points of control together to show the effect.

Summarize:

Controlling the direction of the blur using the "Establish control point" method is applicable to all filters that are relevant to the location.

The way to make the handle disappear is to use the Subselection tool to select the handle, and to change the transparency to 1.
