| 用as做濾鏡效果，每種濾鏡效果對(duì)應(yīng)一個(gè)類別，這些類別將來(lái)會(huì)在Macromedia\Flash 8\語(yǔ)系\First Run\Classes\FP8\flash\filters 這個(gè)資料夾中找到說(shuō)明檔
一、漸變斜角——GradientBevelFilter類別
二、投影——DropShadowFilter類別
三、模煳——BlurFilter類別（這個(gè)最容易了，參數(shù)少）
四、光暈——GlowFilter類別
五、漸層光暈——GradientGlowFilter類別
六、斜角——BevelFilter類別 做法是用new關(guān)鍵字新建一個(gè)相應(yīng)類的對(duì)象，暫時(shí)就叫myfilters吧，然后把這個(gè)對(duì)象增加進(jìn)一個(gè)數(shù)組filters_array，最后把這個(gè)數(shù)組賦值給mc的fliters屬性，大功告成。
我想其中關(guān)鍵應(yīng)該就是建立對(duì)像時(shí)如何設(shè)定里面的參數(shù)吧，我想濾鏡的面板大家都很熟悉的了，那么，我就把a(bǔ)s增加濾鏡的一些參數(shù)和它們的面板相對(duì)照，這樣可能更容易理解。
下面逐個(gè)舉例（都是輔助里的范例啦，里面的參數(shù)名字都是可以改的，不過(guò)我覺(jué)得就用那些名字就蠻好），范例里都有函數(shù)setUpFlatRectangle（也有叫createRectangle的），是用來(lái)做一個(gè)方形mc的。
function setUpFlatRectangle(w:Number, h:Number, bgColor:Number, name:String):MovieClip {
var mc:MovieClip = this.createEmptyMovieClip(name, this.getNextHighestDepth());
mc.beginFill(bgColor);
mc.lineTo(w, 0);
mc.lineTo(w, h);
mc.lineTo(0, h);
mc.lineTo(0, 0);
return mc;
}直接把Script復(fù)制到主場(chǎng)景的第一影格就ok了，不要忘記上面的函數(shù)哦，要注意改函數(shù)名的
一、漸變斜角——GradientBevelFilter類別
Script：
import flash.filters.GradientBevelFilter;
import flash.filters.BitmapFilter;
var art:MovieClip = setUpFlatRectangle(150, 150, 0xCCCCCC, "gradientBevelFilterExample");
//建立新的mc，實(shí)例名：art
var distance:Number = 5;
var angleInDegrees:Number = 225; // opposite 45 degrees
var colors:Array = [0xFFFFFF, 0xCCCCCC, 0x000000];
var alphas:Array = [1, 0, 1];
var ratios:Array = [0, 128, 255];
var blurX:Number = 8;
var blurY:Number = 8;
var strength:Number = 2;
var quality:Number = 3;
var type:String = "inner";
var knockout:Boolean = true;//設(shè)定各個(gè)參數(shù)
var filter:GradientBevelFilter = new GradientBevelFilter(distance, angleInDegrees, colors, alphas, ratios, blurX, blurY, strength, quality, type, knockout);//建立斜角濾鏡對(duì)像filter
var filterArray:Array = new Array();
filterArray.push(filter); //把filter增加進(jìn)數(shù)組filterArray，如果art上有多個(gè)濾鏡效果，就直接增加進(jìn)這個(gè)數(shù)組好了
art.filters = filterArray;//將art的filters屬性設(shè)定為filterArray 下面是Script中的參數(shù)和面板中的參數(shù)對(duì)比
colors、alphas、ratios用來(lái)控制漸變顏色的，colors是色彩，alphas是百分比（這里面是0～1的小數(shù)），ratios是偏移量0～255（可以參考Color類）blurX、blurY是就對(duì)應(yīng)面板里的模煳x、模煳y。strength是面板里的強(qiáng)度，是0～255的數(shù)；quality是品質(zhì)，只有1、2、3分別對(duì)應(yīng)低、中、高distance是距離，預(yù)設(shè)4.0；type是類型，用字串表示，范例中的」inner」是內(nèi)側(cè)，還有outer、fuller；knockout是個(gè)布爾值，表示是否挖空
二、投影——DropShadowFilter類別
import flash.filters.DropShadowFilter;
var art:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample");
var distance:Number = 20;
var angleInDegrees:Number = 45;
var color:Number = 0x000000;
var alpha:Number = 0.8;
var blurX:Number = 16;
var blurY:Number = 16;
var strength:Number = 1;
var quality:Number = 3;
var inner:Boolean = false;
var knockout:Boolean = false;
var hideObject:Boolean = false;
var filter:DropShadowFilter = new DropShadowFilter(distance, angleInDegrees, color, alpha, blurX, blurY, strength, quality, inner, knockout, hideObject);
var filterArray:Array = new Array();
filterArray.push(filter);
art.filters = filterArray;下面是Script中的參數(shù)和面板中的參數(shù)對(duì)比
Distance是距離；
angleInDegrees是角度0～360
blurX、blurY是模煳x、模煳y
strength是強(qiáng)度，Script里是0～5的數(shù)
quality是品質(zhì)，只能是1、2、3，分別對(duì)應(yīng)低、中、高
inner是內(nèi)側(cè)陰影
knockout是挖空
hideObject是隱藏對(duì)像
三、模煳——BlurFilter類別（這個(gè)最容易了，參數(shù)少嘛）
import flash.filters.BlurFilter;
var rect:MovieClip = createRectangle(100, 100, 0x003366, "BlurFilterExample");
var blurX:Number = 30;
var blurY:Number = 30;
var quality:Number = 3;
var filter:BlurFilter = new BlurFilter(blurX, blurY, quality);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;四、發(fā)光——GlowFilter類別
import flash.filters.GlowFilter;
var rect:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample");
var color:Number = 0x33CCFF;
var alpha:Number = .8;
var blurX:Number = 35;
var blurY:Number = 35;
var strength:Number = 2;
var quality:Number = 3;
var inner:Boolean = false;
var knockout:Boolean = false;
var filter:GlowFilter = new GlowFilter(color, alpha, blurX, blurY, strength, quality, inner, knockout);
var filterArray:Array = new Array();
filterArray.push(filter);
rect.filters = filterArray;五、漸變發(fā)光——GradientGlowFilter類別
import flash.filters.GradientGlowFilter;
var art:MovieClip = createRectangle(100, 100, 0x003366, "gradientGlowFilterExample");
var distance:Number = 0;
var angleInDegrees:Number = 45;
var colors:Array = [0xFFFFFF, 0xFF0000, 0xFFFF00, 0x00CCFF];
var alphas:Array = [0, 1, 1, 1, 1];
var ratios:Array = [0, 63, 126, 255];
var blurX:Number = 50;
var blurY:Number = 50;
var strength:Number = 2.5;
var quality:Number = 3;
var type:String = "outer";
var knockout:Boolean = false;
var filter:GradientGlowFilter = new GradientGlowFilter(distance, angleInDegrees, colors, alphas, ratios, blurX, blurY, strength, quality, type, knockout);
var filterArray:Array = new Array();
filterArray.push(filter);
art.filters = filterArray; 這里的參數(shù)跟光暈的類別很像，需要說(shuō)明的就是用來(lái)設(shè)定顏色的那幾個(gè)數(shù)組里的4項(xiàng)依次是表示從外到內(nèi)的顏色的
六、斜角——BevelFilter類別
import flash.filters.BevelFilter;
var distance:Number = 5;
var angleInDegrees:Number = 45;
var highlightColor:Number = 0xFFFF00;
var highlightAlpha:Number = 1;
var shadowColor:Number = 0x0000FF;
var shadowAlpha:Number = 1;
var blurX:Number = 10;
var blurY:Number = 10;
var strength:Number = 2;
var quality:Number = 3;
var type:String = "inner";
var knockout:Boolean = false;
var filter:BevelFilter = new BevelFilter(distance, angleInDegrees, highlightColor, highlightAlpha, shadowColor, shadowAlpha, blurX, blurY, strength, quality, type, knockout);
var rect:MovieClip = createRectangle(100, 100, 0x00CC00, "bevelFilterExample");
rect.filters = new Array(filter);參數(shù)：
highlightColor、highlightAlpha設(shè)定加亮顏色
shadowColor、shadowAlpha設(shè)定陰影顏色 |
