I did something similar to this while trying to implement my own
Bitmap-based magnifying glass (following this example by Grant Skinner:
http://www.gskinner.com/blog/archives/2005/09/flash_8_bluepri.html). You
can use a single MovieClip as the source for as many individual bitmaps
as you want, limited only by your CPU power. Look up the basics of
attaching bitmaps and using BitmapData.draw -- that's all readily
available in the manuals and tutorials. Then just create two bitmaps
attached to two movieclips, and do this:
// assume that source is the MovieClip containing the original image
var matrix:Matrix;
var normalScale:Number = 1.0;
var thumbScale:Number = 0.25;
// draw to the bitmap at the normal scale
matrix = source.transform.matrix;
matrix.scale(normalScale, normalScale);
normalBitmap.draw(source, matrix);
// draw to the bitmap at the thumbnail scale
matrix = source.transform.matrix;
matrix.scale(thumbScale, thumbScale);
thumbBitmap.draw(source, matrix);
Now the normalBitmap (a BitmapData object) has your image at full size,
and thumbBitmap has the image at 1/4 size.
