RE: [Flashcoders] Copy negative pixels from a movie clip using draw()
I had the same problem a while ago, here was my final solution
[as]
import flash.display.BitmapData;
import flash.geom.Rectangle;
import flash.geom.Point;
import flash.geom.Matrix;
//
function staticCloneMC(target, mc, padding) {
var bounds = mc.getBounds(mc);
var offset_y = padding;
var offset_x = padding;
bounds.height = bounds.yMax-bounds.yMin;
bounds.width = bounds.xMax-bounds.xMin;
var w = bounds.width+offset_x;
var h = bounds.height+offset_y;
bounds.x = bounds.xMin-offset_x/2;
bounds.y = bounds.yMin-offset_y/2;
var lvl = target.getNextHighestDepth();
var clip = target.createEmptyMovieClip(dupe_+mc._name+_+lvl, lvl);
var holder = clip.createEmptyMovieClip(holder, 1);
clone_bitmap = new BitmapData(w, h, true, 0x);
holder.attachBitmap(clone_bitmap, 1, auto, true);
clone_bitmap.draw(mc, new Matrix(1, 0, 0, 1, bounds.x*-1, bounds.y*-1));
holder._x = bounds.x;
holder._y = bounds.y;
clip._x = mc._x;
clip._y = mc._y;
clip.bitmap=clone_bitmap
return clip;
}
function animCloneMC(target, mc, padding) {
var lvl = target.getNextHighestDepth();
var clip = target.createEmptyMovieClip(dupe_+mc._name+_+lvl, lvl);
var holder = clip.createEmptyMovieClip(holder, 1);
clip.mc = mc;
clip.padding = padding;
clip.onEnterFrame = function() {
var bounds = this.mc.getBounds(this.mc);
var offset_y = this.padding;
var offset_x = this.padding;
bounds.height = bounds.yMax-bounds.yMin;
bounds.width = bounds.xMax-bounds.xMin;
var w = bounds.width+offset_x;
var h = bounds.height+offset_y;
bounds.x = bounds.xMin-offset_x/2;
bounds.y = bounds.yMin-offset_y/2;
clone_bitmap = new BitmapData(w, h, true, 0x);

clone_bitmap.draw(mc, new Matrix(1, 0, 0, 1, bounds.x*-1,

Subject: [Flashcoders] Copy negative pixels from a movie clip
using draw()
Hi all,
I'm using the BitmapData.draw method, and I've bumped into a
problem. I need to copy all the pixels from a movie clip,
including the pixels which are on negative coordinates. I've
only succeeded copying the ones on positive coordinates. Has
anyone experienced the same thing, and, maybe, have a solution?
I got the basic code from Livedocs, written by Andreas Weber (of this
list?) code below. How would I modify it to accept negative pixels?
Thamks,
Niclas

// 'snapshot'
import flash.display.BitmapData;
// create a clip with visual content
original = this.createEmptyMovieClip(orig,
this.getNextHighestDepth()); original.opaqueBackground =
0xFF; original.lineTo(100,100);
// create a BitmapData object with the same size var
myBitmapData:BitmapData = new BitmapData(original._width,
original._height);
// attach the Bitmap to a clip so that it will be rendered on
screen var copy:MovieClip = this.createEmptyMovieClip(cop,
this.getNextHighestDepth()); copy.attachBitmap(myBitmapData,
this.getNextHighestDepth()); copy._x = 300;
// take a 'snapshot'
myBitmapData.draw(original);

Re: [Flashcoders] Copy negative pixels from a movie clip using draw()
Hi all, I'm using the BitmapData.draw method, and I've bumped into a problem. I need to copy all the pixels from a movie clip, including the pixels which are on negative coordinates. I've only succeeded copying the ones on positive coordinates. Has anyone experienced the same thing, and, maybe, have a solution? Use a transformation matrix as the second parameter of the .draw() method (check the documentation). You can use it to move the 'data' before drawing (ie, to get 100 pixels width from the negative side, you'd move it 100 pixels right).

Mike,
You have, quite literally, saved the day! Thanks a lot for the very
useful and quick response.
