FLEX实例：几款滤镜效果实例.

1:聚光灯效果：

 实例：

• ambientColor - color to apply to all pixels of the image
• angle - angle at which the spotlight is projected (in degrees)
• azimuth - angle between the image plane and the spotlight (in degrees)
• coneAngle - angle of the spotlight's "opening" (in degrees)
• distance - distance from the spotlight to the center point
• intensity - intensity of the spotlight
• position - x, y, z position of the spotlight
• spotColor - color of the spotlight

2:放大镜效果：

 实例：

• center ([0-2048, 0-2048]) - the center coordinates of the magnified area
• outerRadius (0-500) - the radius of the magnified part of the image
• innerRadius (0-500) - the radius of the fully magnified part of the image
• magnification (1-50) - the amount to magnify the image by (e.g. set to 2 for a 2x magnification)

3：缩放模糊效果：

实例：

• amount (0 - 0.5) - the amount of blur to apply
• center ([0 - 2048, 0 - 2048]) - the focal point of the blur

4：浮雕效果：

实例：

• amount (0 - 20) - the amount to sharpen the image by
• radius (0 - 1) - pixel distance to sample from

5：水波效果：

实例：

• amplitude (0-1) - the height of the waves
• frequency (0-.54) - how close together the waves are.  Higher value = more waves.
• progress (0-1) - percentage of the wave sequence.  Animate from 0 to 1 to get a smooth wave effect.
