Calc

Performs a calculation on either a frame or the table items inside the frame.

Parameters

NameDefaultMeaning
nameThe name of the final attribute/column
valueThe value to be written. Substitutable.
whereA condition that must be met for the calculation to happen.

Description

This function performs a calculation on a frame, or - if the frame contains a table - the individual items within the table.

This will normally be applied to every column/frame, unless a where condition is specified. If a 'where' condition exists, the calculation will only happen on frames and columns that match the condition.

Example

If the frame contains the following attributes…

AttributeValue
Width100
Height100
{
   "type": "calc",
   "name": "Area",
   "value": "{Width} * {Height}"
}

The final results will include the Area attribute with a value of 10,000. If 'Width' and 'Height' were in the table instead, a new column called 'Area' would be added.
