bitmapData

[Boombanguk]

How would I use the bitmapData object to copy a vector image?

BitmapData.loadBitmap(linkageId);

where the linkageId is a movie clip in the library which has vector graphics in it, not bitmaps?

doesn't seem to work.

thanks for any advise.

You need to attach it to a movieclip.

import flash.display.BitmapData;

var linkageId:String = "libraryBitmap";
var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId);
trace(myBitmapData instanceof BitmapData); // true

var mc:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
mc.attachBitmap(myBitmapData, this.getNextHighestDepth());

thats exactly the code I used and it didn't work.

I stuck a load of vector squares inside a movie clip, and that was the string name I used in the above code, and it traced as false...

the only way it seemed to work was when the linkID was an actual bitmap

any ideas??

You have to use the draw method for a bitmapData object to make a copy of a MovieClip/Textfield. You can only use the linkID on bitmaps in your library with the loadBitmap method.

I thought it would be the draw method, but i looked at that, and it only takes a bitmapData object again the same problem??

[cancerinform]

That is true, but you can create a transparent Bitmapdata, which nobody sees and place it anywhere you want. Then you place the movieclip to be drawn outside your movie.

import flash.display.BitmapData;
import flash.geom.Rectangle;
import flash.geom.Matrix;
import flash.geom.ColorTransform;
var myBitmapData:BitmapData = new BitmapData (100, 80, true);
var mc_1:MovieClip = this.createEmptyMovieClip ("mc", this.getNextHighestDepth ());
mc_1.attachBitmap (myBitmapData, this.getNextHighestDepth ());
mc_1._x = 200;
mc_1._y = 200;
var mc_2:MovieClip = clip;
var myMatrix:Matrix = new Matrix ();
myMatrix.rotate (Math.PI / 2);
var translateMatrix:Matrix = new Matrix ();
translateMatrix.translate (70, 15);
myMatrix.concat (translateMatrix);
var myColorTransform:ColorTransform = new ColorTransform (0, 0, 1, 1, 0, 0, 255, 0);
var blendMode:String = "normal";
clip_2.onPress = function ()
{
    myBitmapData.draw (mc_2, myMatrix, myColorTransform, blendMode);
};

trying to understand your code.

clip is a Mc in the library only? or its already placed on the stage?? tried both, neither worked.

[cancerinform]

clip is on stage but placed outside. See attachment.

[Boombanguk]

ok just had a look at that.

it just creates a blue rectangle...what I need though is for it to put on the screen a vector square which is in a clip, which ideally is in the library, not already on the stage......can't this be done using the bitmapData object??

[Boombanguk]

the reason im asking this, is because I'm using a scroll engine that uses the bitmapData object, but insted of using bitmap tiles I want to use vector tiles..

[cancerinform]

Ok, use the example i posted. Delete clip from stage and create linkage with clip as identifier. Then modify the script by adding these two lines:

var mc_2:MovieClip = this.attachMovie("clip","clip",this.getNextHighest Depth());
mc_2._visible = false;

Whatever the new object will look like you need to set in the draw method.

[Boombanguk]

did that, it still just plots a blue rectangle...??

also does that mean to use the draw method it has to use an instance ? and can't just use one from the library??

[cancerinform]

It cannot just take an clip from the library (to my knowledge ), but needs to place an instance on stage. The blue rectangle is just what has been coded by the draw method. You can manipulate that as you like.
