Error #2015 Invalid BitmapData

[Domox]

I get the following:



ArgumentError: Error #2015: Invalid BitmapData.
at flash.display::BitmapData$iinit()
at com.psyphon.pcl.display::BitMapRenderer$iinit()[C:\Users\Dylan\Desktop\POC\com\psyphon\pcl\display \BitMapRenderer.as:40]
at com.psyphon.poc::Main$iinit()[C:\Users\Dylan\Desktop\POC\com\psyphon\poc\Main.as :46]


Whenever I initialize the following class using:


renderer = new BitMapRenderer(stage.width, stage.height);


And it does not matter what stagesize i set so it isnt a bitmapdata size/memory issue (AFAIK)....

so, i was using stage.width and stage.height, when i should have been using stage.stagewidth/height. Thanks to Sirisian for pointing it out! :P

And she works! Thanks to everyone for your insight into the efficiency of copyPixels() :P

I was able to produce this error by adding a bunch of bitmaps to the stage, then overwriting them again and again (on mouse move) eventually the error came up. I fixed it by using this removeChild script so that I was not just adding children overtop like an overwrite, and it seemed to do the trick
removeChildren("clipCommonWordInTheNameOfTheInstances",this);

function removeChildren(precursor:String,container:DisplayO bjectContainer) {
var child:DisplayObject;
for (var i:uint=0; i < container.numChildren; i++) {
child = container.getChildAt(i);
if (child.name.indexOf(precursor) != -1) {
removeChild(child);
}
}
}

Here it is a bit more readable.



function removeChildren(precursor:String,container:DisplayO bjectContainer) {
var child:DisplayObject;
for (var i:uint=0; i < container.numChildren; i++) {
child = container.getChildAt(i);
if (child.name.indexOf(precursor) != -1) {
removeChild(child);
}
}
}
