In this example we provide a first, step by step look at how to format areas in a drawing using the Style pane. We can specify the same formatting for all areas or use a field to automatically set formatting, a process usually known as thematic formatting. |

A common GIS task is to format the size of points in a drawing based on some value. For example, the size of points that represent cities might be formatted based on the value of the city's population, with cities that have larger populations being marked by larger point icons. This is an example of thematic formatting and is easy to do using the Style dialog. |

The visualization capabilities of Manifold using Style can be exploited to provide many visual effects. This topic provides some examples of how to use Style in unexpected ways to create a range of more elaborate effects. |
|
When using Style to format a drawing it is a really bad idea to use the same color for objects that is used for the background color. It can also be a bad idea to use transparent color for objects. This topic illustrates why. |
|
This topic provides a step by step example of adding, deleting and editing intervals in the Style dialog that are used for thematic formatting. |
|
Working with style overrides to individually style areas, to use or not use style overrides, to find all records using style overrides and to clear style overrides. |
|
This example creates a complex point style, which uses a variety of different colors within the different effects tabs in the Point Style dialog. |
|
The Move parameter for symbols allows us to move symbols in an angular direction even as we rotate them. This example shows how to create point symbols that are clock faces with hands, using Move and Rotate. |
|
We can use effects from all of the Line Style dialog tabs to create a more complex line style. This example shows how to create a line style with an arrowhead symbol at the end of the line, a symbol at the beginning of the line and accessory lines in different colors to the left and right of the main line. |
|
We can use bitmap images as "fill" symbology for areas, including for the fill of the area itself, or as fill for Inner or Outer effects. In this example we use Style Overrides to fill different areas in a map of provinces with a different bitmap image pattern. |
|
Areas are often filled with bitmap images that form a seamless pattern when tiled. If we like, we can use any bitmap image that can be used as a symbol, which will repeat within the area. |
|
The Inner and Outer effects with area styles can use bitmap images for fills. We first illustrate an Outer effect using a bitmap, and then add an Inner effect. |
|
Style properties for drawings such as colors for areas are stored in human readable JSON values as properties in the mfd_meta system table. This example shows how we can copy formatting from one drawing to another by simply copying values between records in the mfd_meta table. |
