bounds

Utility

Some utils for transforming InDesign bounds arrays.

Install

npm install @extendscript/ind.util.bounds

Include

#include 'node_modules/@extendscript/ind.util.bounds/bounds.js'

Use

Load the module by creating a reference.

var Bounds = Sky.getUtil("bounds")

getInfo( bounds )

This function collects some extra data from the bounds. It returns an object with the following keys:

• bounds Array ([y1, x1, y2, x2])
• height Number
• width Number
• topLeft Object ({x: Number, y: Number})
• topCenter Object ({x: Number, y: Number})
• topRight Object ({x: Number, y: Number})
• midLeft Object ({x: Number, y: Number})
• midCenter Object ({x: Number, y: Number})
• midRight Object ({x: Number, y: Number})
• botLeft Object ({x: Number, y: Number})
• botCenter Object ({x: Number, y: Number})
• botRight Object ({x: Number, y: Number})

offset( bounds, offset)

Returns an offset ([x,y]) of bounds values.

normalise( bounds, offset )

Returns the normalised bounds ([y1, x1, y2, x2]). You can give it an optional offset. Either a single number or array that defines [x,y].

Therefore the given bounds [10,11,20,21] transform to [0,0,10,10] if no offset is given. When we add [1,2] as offset we get [2,1,12,11]

getRelativeOfset( bounds, relativeToBounds )

This function returns the relative ofset as an info object as described above (See getInfo).

X--------X--------X
|  |   |   |      |
|--X---X---X------|
|  |   |   |      |
|--X---X---X------|
X  |   | x |      X
|--X---X---X------|
|  |   |   |      |
|  |   |   |      |
|  |   |   |      |
X--------X--------X

BEWARE: This function expects both bounds to be in the same X-Y coordinate space and measure unit!

Test

We can test the code against a range of targets:

npm run test myTarget

We keep a log of test results
