BOX record

A BOX record can appear after a LAYER record has been issued. The BOX record defines one or more rectangular data objects.

The header flags byte is not used.

The BOX record contains the following fields:

bytes field name purpose
4 left left value
4 bottom bottom value
4 right right value
4 top top value
? [repeat] repeat for multiple boxes

The first four integers define a box, and a record can contain multiple box definitions (four integers per box). Each box is given the properties currently in effect, and is assigned to the layer currently in effect.
