### 7.8.9 Effect Filters/Tear Paper

Tearing paper isn‘t so simple as it looks at the first sight. You can see that quite easily at the number of options available in the Paper Tearing dialog. In order to understand these options there has to be a little bit of theory first:

- If you tear a piece of paper apart, you usually get 2 pieces.
- The tear edges of the two resulting pieces fit together.
- At the tear edges there is usually a white area, on which nothing of the content of the page is visible. At the second piece of paper at the corresponding location the content is visible at the edge. The white area, where no content is visible, is called "edge" in the dialog.
- Often the white area/edge, changes from one piece of paper to the other, so at some locations the content of the paper is visible until the tear edge and at some locations not.
- In PhotoLine the white area/the edge is calculated by moving two roughened lines. The intersections of the two lines are the edge.

With this basic knowledge the options of Tear Paper are understandable.

Edge Mode control, how the white area is calculated. In practice there is only the case, that the white area is on both resulting pieces. But your computer has more choices:

- No Edge: there is no white area
- Top Edge: only the piece at the top has a white area
- Bottom Edge: only the piece at the bottom has a white area
- Two Edges: both pieces have a white area. This is most realistic, but has the disadvantage, that the resulting pieces do not fit together on the computer.

Parts controls, whether to create one or two pieces of paper.

Corners controls the number of corner are created at the tearing. If you want to tear paper, this value should be 0, because this value means, that the tearing is not made of single corners but is continuous. Corners are only needed if you don‘t want to create a tearing of paper but the breaking of hard material.

Roughness defines, how rough the two lines - used by PhotoLine to calculate the edge - are roughened. Thickness is how far they are moved apart.

Edge Color is the color of the created edges.

Edge 1 and Edge 2 control, how the two line used for edge creation are created. In edge mode No Edge Edge 2 has no effect and is not used. The smaller Detail is, the fewer waves are in the corresponding line. Intensity controls the height of the waves..

Position set ups, where the tearing will occur.

Paper Tearing can not only be used with image layers but also with vector layers and whole groups.
