Instructions

1. Open the Filter Browser, and add a new filter set using the small + icon located in the middle of the browser. This will create a new ‘untitled’ filter set for you. This will appear in the top section of the Filter Browser. If you already have filter sets created, clicking the + button will duplicate the selected filter set.
2. Select Wave from the list of available filters in the lower section of the Filter Browser. 
3. Double click on the name of the new filter set in the top section of the browser, and name it appropriately.
   
4. Edit the variables to achieve the result you need. 
   • Number of waves - controls how many waves appear on the design
   • Wave amplitude - controls the size of the waves, calculated as a percentage of the image width/height. This relates to the depth of each wave measured from the original straight line, or centre point. If you are only using the filter on a selected area, the wave amplitude will be a percentage of the selection width/height, not the design width/height.
   • Wave offset - relates to the start point of the wave, for example the crest or trough
   • Wave type - the direction of the waves can be either horizontal or vertical

In the snapshot below, the original data is on the left, and the filtered data is on the right.

Applying the filter

There are several ways to apply a filter:

• Click Apply - this will apply the filter to the active layer(s), and within a selection if there is one present in your file
• Click Make Layer - this will make a new layer in your file containing the filtered effect, leaving the original layer untouched
• Apply the filter using the Brush Tool - when you have finished building your filter set, simply close the Filter Browser. Then, open the Brushes Library, and select the filter you have just made from the drop down menu shown in the snapshot below. You can now paint with your filter.

Applying the filter over a repeat join

Due to the nature of the filter, it does not repeat well over repeat joins.  However, you can manually correct the repeat join by copying and pasting elements over the join.
