Skaler billedet proportional
Hej
Jeg har noget as3 kode her for mit baggrunds billede:
function drawImage():void{
StageWidth = stage.stageWidth;
StageHeight = stage.stageHeight;
if(tileImage){
imageHolder.x = 0;
imageHolder.y = topMargin;
imageHolder.graphics.clear();
imageHolder.graphics.beginBitmapFill(image.bitmapData);
imageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
imageHolder.graphics.endFill();
}
if(fsBgImage){
maxWidth = StageWidth;
maxHeight = (StageHeight-topMargin-bottomMargin);
rawWidth = image.bitmapData.width;
rawHeight = image.bitmapData.height;
var MTRX:Matrix = new Matrix();
var scaleX:Number = maxWidth/rawWidth;
var scaleY:Number = maxHeight/rawHeight;
maxWidth = rawWidth * scaleX;
maxHeight = rawHeight * scaleY;
MTRX.scale(scaleX, scaleY);
scaledImage = new BitmapData(maxWidth,maxHeight);
scaledImage.draw(image.bitmapData, MTRX,null,null,null,true);
imageHolder.x = 0;
imageHolder.y = topMargin;
imageHolder.graphics.clear();
imageHolder.graphics.beginBitmapFill(scaledImage);
imageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
imageHolder.graphics.endFill();
tileImage = false;
}
Jeg vil nu gerne have til at når man gør vinduet mindre skal det skalere proportionalt?
Nogen der kan hjælpe med det?

hele koden for baggrunden :
if(useImageBackground){
if(tileImage){
if(altBgImage){
imageHolder.x = stage.stageWidth;
imageHolder.y = stage.stageHeight;
imageHolder.scaleX = scaleX
imageHolder.graphics.clear();
imageHolder.graphics.beginBitmapFill(image.bitmapData);
imageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
imageHolder.graphics.endFill();
}
else{
altImageHolder.x = 0;
altImageHolder.y = topMargin;
altImageHolder.graphics.clear();
altImageHolder.graphics.beginBitmapFill(altImage.bitmapData);
altImageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
altImageHolder.graphics.endFill();
}
}
if(fsBgImage){
if(altBgImage){
maxWidth = StageWidth;
maxHeight = (StageHeight-topMargin-bottomMargin);
rawWidth = image.bitmapData.width;
rawHeight = image.bitmapData.height;
var MTRX:Matrix = new Matrix();
var scaleX:Number = maxWidth/rawWidth;
var scaleY:Number = maxHeight/rawHeight;
maxWidth = rawWidth * scaleX;
maxHeight = rawHeight * scaleY;
MTRX.scale(scaleX, scaleY);
scaledImage = new BitmapData(maxWidth,maxHeight);
scaledImage.draw(image.bitmapData, MTRX,null,null,null,true);
imageHolder.x = 0;
imageHolder.y = topMargin;
imageHolder.graphics.clear();
imageHolder.graphics.beginBitmapFill(scaledImage);
imageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
imageHolder.graphics.endFill();
tileImage = false;
}
else{
maxWidth = StageWidth;
maxHeight = (StageHeight-topMargin-bottomMargin);
rawWidth = altImage.bitmapData.width;
rawHeight = altImage.bitmapData.height;
var MTRX2:Matrix = new Matrix();
var scaleX2:Number = maxWidth/rawWidth;
var scaleY2:Number = maxHeight/rawHeight;
maxWidth = rawWidth * scaleX2;
maxHeight = rawHeight * scaleY2;
MTRX2.scale(scaleX2, scaleY2);
scaledImage = new BitmapData(maxWidth,maxHeight);
scaledImage.draw(altImage.bitmapData, MTRX2,null,null,null,true);
altImageHolder.x = 0;
altImageHolder.y = topMargin;
altImageHolder.graphics.clear();
altImageHolder.graphics.beginBitmapFill(scaledImage);
altImageHolder.graphics.drawRect(0, 0, StageWidth, (StageHeight-topMargin-bottomMargin));
altImageHolder.graphics.endFill();
tileImage = false;
}
}
