blur a background

[Ralph DiMola]

Mark,

Thanks!!! Wish I knew that before I did it by brute force. I ripple thru all
controls(including mobile controls) and disable them (also remember ones
that were already disabled), setting the transparency to like 20% setting
all the card's background to gray. Then put a new group on the card and do
whatever and then when the user is done remove the group and re-enable all
controls set the transparency back yada-yada-yada. The way you are
suggesting is very elegant indeed.

Hi CHris,

Import a snapshot of the card. Set the blendLevel of the new image control
to 50 and move the image control 3 or 4 pixels to the top-left. You can
easily to this by script. You don't need to use  static picture for this.
You can do this dynamically, to make correspond to the current state of the
screen.

this and am not sure how. If it's not possible, can something be done to an
image to create this effect, and then have that image imported into an LC
stack?
