You could set the imagesource of the characters into the field, take the
snapshot, then "set the text of field "whatever" to the text of field
"whatever" to revert.
Did a quicky test, and it seems to work well enough.
local simageOn
on mouseup
lock screen
if sImageOn is empty then put false into sImageOn
if sImageOn then
set the text of field 1 to the text of field 1
put false into sImageOn
else
repeat with i = 1 to the number of chars in field 1
set the imagesource of char i of field 1 to 1008
end repeat
put true into sImageOn
end if
unlock screen
end mouseup
