Hi

i’ve got a bitmapdata “bmp”  
already transparent, already created  
i am loading a sequence of pngs with an alpha channel into it  
after the new png is loaded i want to ERASE the contents of bitmap  
and draw the new png so the images do not accumulate…

floodfill method is not working,

//SET TRANSPARENT (not working)  
bmp.floodFill(0, 0, 0x00000000);  
//REDRAW  
bmp.draw(target\_mc)

all help appreciated,  
jhave

try something like:

```auto
var color:Number = 0x00000000;
bmp.fillRect(bmp.rectangle, color);

```

Hope this helps :thumb:
