Applying the Edges in PSP
I. The Quick Way
1. Open an edge file from the edges sub folder in PSP.
2. Open a photo file.
3. Activate the photo window and choose New | From Image from the Mask menu.
4. In the "Add Mask From Image" dialog select the edge file in the "Source window" combo box and "Source Luminance" in the "Create mask from" frame. Make sure "Invert mask data" check box is deactivated.
5. After pressing OK, the edge will be applied as a mask onto the photo.
6. Select Merge | Merge All (Flatten) from the Layers menu to make the background opaque again.
II. The Advanced Way
1. Open an edge file from the edges sub folder in PSP.
2. Open a photo file.
3. Activate the edge window and choose Resize from the Image menu and enter the pixel size of the photo file to adapt the edge to the size of the photo.
4. Press <Ctl + A> to select the whole edge and press <Ctl + C> to copy it to the clipboard.
5. Switch to the other photo window and press <Ctl + L> to paste the edge as a layer into the photo.
6. Select Properties from the Layers menu.
7. In the Layer Properties dialog choose Multiply from the Blend Mode combo box and press OK.
8. Select Merge | Merge All (Flatten) from the Layers menu to make the background opaque again.
Using the above instructions will result in a black background. To get a white
background at the end, apply Negative Image from the Colors menu right
after step 1. And in step 7 select Screen as the blend mode instead of
Multiply.
