PES object section

Some basic forms are found within many different PES sections.

Geometry

Extents

The distinction between these two copies of the same data is currently unknown.

Affine transform

And affine transformation is 9 floating point values, usually stored as 6 (because the other three are always 0, 0, 1). It’s a matrix by which any series of affine geometric operations namely scaling, skewing, and transforming can be performed in a single calculation for any number of points. We should usually just use the identity matrix.

Type	Bytes	Value	Description
f32	4	1.0f (identity)	Row 1 column 1, scale X
f32	4	0.0f (identity)	Row 2 column 1, skew Y
f32	4	0.0f (identity)	Row 1 column 2, skew X
f32	4	1.0f (identity)	Row 2 column 2, scale Y
f32	4	0.0f (identity)	Row 1 column 3, translation X
f32	4	0.0f (identity)	Row 2 column 3, translation Y

Block Description

These are the preamble for most shape forms like CEmbRect and CEmbCirc section and effectively all objects which can be filled shapes with stitches.
