[. . . ] The first element in the colors array corresponds to the first element in the alphas array and in the ratios array, and so on. Think of the gradient glow filter as a glow that emanates from the center of the object (if the distance value is set to 0), with gradients that are stripes of color blending into each other. The first color in the colors array is the outermost color of the glow. The last color is the innermost color of the glow. Each value in the ratios array sets the position of the color on the radius of the gradient, where 0 represents the outermost point of the gradient and 255 represents the innermost point of the gradient. The ratio values can range from 0 to 255 pixels, in increasing value; for example [0, 64, 128, 200, 255]. Values from 0 to 128 appear on the outer edges of the glow. Values from 129 to 255 appear in the inner area of the glow. Depending on the ratio values of the colors and the type value of the filter, the filter colors might be obscured by the object to which the filter is applied. GradientGlowFilter (flash. filters. GradientGlowFilter) 647 In the following code and image, a filter is applied to a black circle movie clip, with the type set to "full". For instructional purposes, the first color in the colors array, pink, has an alpha value of 1, so it shows against the white document background. (In practice, you probably would not want the first color showing in this way. ) Note the last color in the array, yellow, obscures the black circle to which the filter is applied: var colors = [0xFFCCFF, 0x0000FF, 0x9900FF, 0xFF0000, 0xFFFF00]; var alphas = [1, 1, 1, 1, 1]; var ratios = [0, 32, 64, 128, 225]; var myGGF = new GradientGlowFilter(0, 0, colors, alphas, ratios, 50, 50, 1, 2, "full", false); To achieve a seamless effect with your document background when you set the type value to "outer" or "full", set the first color in the array to the same color as the document background, or set the alpha value of the first color to 0; either technique makes the filter blend in with the background. 648 ActionScript classes If you make two small changes in the code, the effect of the glow can be very different, even with the same ratios and colors arrays. Set the alpha value of the first color in the array to 0, to make the filter blend in with the document's white background; and set the type property to "outer" or "inner". Observe the results, as shown in the following images. Keep in mind that the spread of the colors in the gradient varies based on the values of the blurX, blurY, strength, and quality properties, as well as the ratios values.

The higher the value, the more color is imprinted and the stronger the contrast between the glow and the background. A value of 0 means that the filter is not applied.

IME) Object | +-System. IME public class IME extends Object The IME class lets you directly manipulate the operating system's input method editor (IME) in the Flash Player application that is running on a client computer. You can determine whether an IME is installed, whether or not the IME is enabled, and which IME is enabled. You can disable or enable the IME in the Flash Player application, and you can perform other limited functions, depending on the operating system. Input method editors let users type non-ASCII text characters in Asian languages such as Chinese, Japanese, and Korean.
