This may be what u are looking for:

-- Put this script in your eraser sprite
property click
property base
property eraser

on beginSprite me
click = false
-- sprite to be erased
base = sprite(1)
-- eraser sprite
eraser = sprite(2)
base.member.image.fill(base.member.image.rect,rgb(0,0,0))
eraser.member.centerregPoint = true
end me

on mouseDown me
eraser.loc = the mouseLoc
click = true
end

on mouseUp me
click = false
end

on exitframe
if(click) then
eraser.loc = the mouseLoc
if sprite 2 intersects 1 then
bImage = base.member.image
eImage = eraser.member.image
eRect = eImage.rect
eOffsetX = eraser.member.image.width/2.0
eOffsetY = eraser.member.image.height/2.0
offset = point(the mouseLoc.locH - base.left, the mouseLoc.locV - base.top)
r = rect(offset[1]-eOffsetX,offset[2]-eOffsetY,offset[1]+eOffsetX,offset[2]+eOffsetY)
--bImage.copyPixels(eImage,r,eRect)
bImage.fill(r,rgb(255,255,255))
end if
end if
end
