Module types 

Core types for Altium file parsing.

This module contains fundamental types used throughout the library:

• Coordinate types (Coord, CoordPoint, CoordRect)
• Unit types for measurement conversions
• Layer definitions for PCB layers
• Color type for Altium colors
• Parameter collection for key-value storage
• Unknown fields for non-destructive editing

Structs

Color

Color type stored as Win32 COLORREF (BGR format).

Coord

Internal coordinate value, stored as a fixed-point integer.

CoordPoint

2D point with X and Y coordinates.

CoordPoint3D

3D point with X, Y, and Z coordinates.

CoordRect

Rectangle defined by two corner points.

Layer

PCB layer identifier.

ParameterCollection

Collection of key-value parameters.

ParameterValue

Value of a parameter with typed conversion methods.

UnknownFields

Container for unknown/unrecognized fields during parsing.

Enums

MaskExpansion

Mask expansion mode (replaces manual bool + value Coord pairs).

Unit

Measurement units supported by Altium.

Functions

coord_to_dxp_frac

Split a raw coordinate value into DXP integer and fractional parts.

dxp_frac_to_coord

Combine DXP integer and fractional parts into a raw coordinate value.
