» Title: Creative DW Image Show PRO
» Description: Creative DW Image Show PRO is a Dreamweaver extension which enables the user to create multimedia presentations. It combines the features of the popular Creative DW Image Show with the ability to add professional text effects to slides (similar to After Effects). The product is very customizable: the user can choose the duration of the transition effects, the slide motion start and end position, zoom and panning type for both images and texts.

Math(object) only understands angles in radians and our MC understands angles
in degrees. So the rad must be converted into degrees. 180 / (pi /
rad). The number is then rounded to the lowest whole number.
//Converts
radians into degrees.
deg = Math.floor(180/(Math.PI
/ rad));
In trig the positive angle is
counterclockwise but in Flash it is just the opposite. A negative number multiplied
by another negative number will return a positive value. Which is exactly what
happens during the Math.pow function, so to compensate for the negative angle
we'll just change the deg into a negative number if y is less
than zero. The preceeding formulas cannot calculate the value for the 180th
degree, but that can be fixed. The y value needs to be rounded down to
a whole number so Flash can ask y for an equals value of zero. If y
equals zero and x is in the negative realm Flash can give the the deg
an assignment of 180.
These
trace actions are totally optional, but very useful during the development process.
When you test the movie you can bring up the values for your variables in the
output window by clicking the mouse. The trace actions won't appear when the
movie is placed in a browser.
