# Wiping the Canvas

You can wipe the result image when you want to apply a uniform colour at the current frame in a single brush stroke. Alternatively, you can use a source, to wipe over an image.

To wipe the result image with a colour or a source:

1. From the View box, select Result (F4).
2. Do one of the following:
   - Pick the wipe colour by clicking the colour pot to the right of the Wipe button.
   - Select the source in the Sources list and enable Use Source.
3. To display the source as an overlay of the result image, enable Overlay (Tab). You can apply transformations to the source before you apply the wipe:
   - To interactively offset a source image, press Ctrl+Shift and drag the source. See Previewing a Reveal Operation Using a Reference Image.
   - To scale the source, enter a value in the Scale field.
   - To rotate the source, enter the angle of rotation in the Rotate field.
4. Do one of the following:
   - Click Wipe to wipe the front and matte.
   - Click the Wipe dropdown list and select Wipe F to wipe the front only.
   - Click Wipe dropdown list and select Wipe M to wipe the matte only.
