@ -772,12 +772,7 @@ Suppress a TV station logo by a simple interpolation of the surrounding
pixels. Just set a rectangle covering the logo and watch it disappear
(and sometimes something even uglier appear - your mileage may vary).
The filter accepts parameters as a string of the form
"@var{x}:@var{y}:@var{w}:@var{h}:@var{band}", or as a list of
@var{key}=@var{value} pairs, separated by ":".
The description of the accepted parameters follows.
This filter accepts the following options:
@table @option
@item x, y
@ -807,12 +802,6 @@ Some examples follow.
Set a rectangle covering the area with top left corner coordinates 0,0
and size 100x77, setting a band of size 10:
@example
delogo=0:0:100:77:10
@end example
@item
As the previous example, but use named options:
@example
delogo=x=0:y=0:w=100:h=77:band=10
@end example
