hi guys
should be a quickie for someone
i've got a bitmapdata object which is being written to by a quickie drawing
api that i wrote. It works absolutely great. The problem is that when i
.dispose() of the attached bitmap, i cannot write to it any more
i've tried recreating it but with no joy - i really hope you can help
<code>
var mcBitmap: MovieClip = this.mcBitmap;
var bmp:BitmapData= new BitmapData(169, 136, true, 0x000000);
this.onMouseDown = startDrawing;
this.onMouseUp = stopDrawing;
function setupClearButton():Void
{
mcClearButton.onRelease = function():Void
{
bmp.dispose(); // clears the bmp
bmp = new BitmapData(169, 136, true, 0x000000); // tried to
reinstantiate the bitmapdata but it doesn't work
}
}
function startDrawing():Void
{
setLineStyle(); // set linestyle to current style
var point:Object = {x:_xmouse, y:_ymouse}; // object to be used with
globalToLocal to change to local coordinates
mcDrawing.globalToLocal(point);
mcDrawing.moveTo(point.x, point.y);
this.onMouseMove = function():Void
{
var point:Object = {x:_xmouse, y:_ymouse}; // object to be used
with globalToLocal to change to local coordinates
mcDrawing.globalToLocal(point);
mcDrawing.lineTo(point.x, point.y);
}
}
}
function setLineStyle():Void
{
mcDrawing.lineStyle(nLineWeight, nCurrentColour, nLineAlpha);
}
function stopDrawing():Void
{
delete this.onMouseMove;
bmp.draw(mcDrawing); // copy user stroke to bmp BitmapData
mcDrawing.clear(); // clear user drawing
}
}
</code>
thanks
alz
