Drop shadow adobe flash

Filters with lower values are rendered more quickly. For most applications, a quality value of low, medium, or high is sufficient. Although you can use additional numeric values up to 15 to achieve different effects, higher values are rendered more slowly. Instead of increasing the value of quality , you can often get a similar effect, and with faster rendering, by simply increasing the values of the blurX and blurY properties. The strength of the imprint or spread.

The higher the value, the more color is imprinted and the stronger the contrast between the shadow and the background. Valid values are from 0 to The default is 1. Filters: Retrieving Data from Server Retrieving Data from Server Classes x. Package flash. The shadow algorithm is based on the same box filter that the blur filter uses.

You have several options for the style of the drop shadow, including inner or outer shadow and knockout mode. You can apply the filter to any display object that is, objects that inherit from the DisplayObject class , such as MovieClip, SimpleButton, TextField, and Video objects, as well as to BitmapData objects. The use of filters depends on the object to which you apply the filter: To apply filters to display objects use the filters property inherited from DisplayObject.

Setting the filters property of an object does not modify the object, and you can remove the filter by clearing the filters property. To apply filters to BitmapData objects, use the BitmapData. Calling applyFilter on a BitmapData object takes the source BitmapData object and the filter object and generates a filtered image as a result.

Add a comment. Active Oldest Votes. Usually, dropshadows are done like so: copy your bitmap's alpha channel blur the copied alpha channel a gaussian blur should be fine move the copied alpha channel down and to the right use the copied alpha channel to darken the background that is, multiply the background's RGB values by the inverse value from the alpha channel; this is the same as combining the alpha channel with an all-black bitmap and alpha-blending that over the background draw the original bitmap also using alpha-blending.
