- Open Quantum GIS workspace and in the menu bar select ‘settings’ --> ‘style manager’ --> choose ‘fill’ tab.
- Click ‘add’ button which opens ‘symbol properties’ --> click ‘+’ button to add the number of strips to requirement. ‘Simple fill’ option would be the default.
- Select the ‘symbol layers’ and change the ‘symbol layer type’ to ‘line pattern fill’ for all the added .
- Select every single layer and in ‘symbol layer properties’ set the ‘angle’ at 45 degree and ‘line width’ to 2.50 which makes the strips visible as well as provides space for the subsequent layers.
- The ‘distance’ depends upon the number of layers present, it is 7.50 ( 2.5 times 3) for 3 layers (3 owners), 10.00 for 4 layers and 12.50 for 5 layers which is all based on the ‘line width’, since it is set at 2.50 the ‘distance’ are all in the multiples.
- The ‘offset’ varies for each individual layer, as multiples of 2.50. This is done to avoid the strips from overlapping. The first layer has an offset value of 0.00.
- Click ‘ok’ after finishing the style and save it with a new name for the style and click ‘ok’.
- For each polygon a specific style can be chosen for each class by opening ‘layer properties’ → ‘symbol selector’ and selecting the anyone of the saved styles, while the colours of the strips can be edited by clicking the change button.
- The styles which were created can also be sent to other users by exporting the created styles into a .xml file.
- These .xml files can be imported as respective styles into the ‘style manager’ of other systems.
- These styles with strips of solid fills can be replaced with other patterns. These are a few examples of the above.
