Transforms offer a chance to alter the value returned from a binding. For example, you can bind a property to an integer value and use a transform to map the numerical value to a particular color, all from the same interface. 

Transforms can be used as a way of splitting up complex expressions. You can make several simple expressions and chain them together as several transforms to manipulate your original value.

When multiple transforms are applied to a single binding, they are executed in order from top to bottom.

Map

The Map Transform allows you to set up a map of input values to output values. Inputs can be anything from specific values or strings, to numeric ranges of values. Each input value can then be mapped to an output value, such as a string, integer, color, style, etc. A great example of this is mapping values to colors, so that you can easily show state changes.


Format

The Format Transform applies a format string to the value returned from the binding, allowing you to format the output in any way. The format can be something like a date format or a number format.


Script

The Script Transform will run a script that allows you to manipulate the value returned from the binding using any Python script you want. 


Expression

The Expression Transform runs an expression on the original value so you can manipulate it without creating more complex logic. This is most useful when you are indirectly binding to a Tag but still want to apply an expression to it, it can now be done in two distinct steps.
