File Format

Introduction

The binary file is made up of a series of data blocks where each data block looks like this:

Data	Type	Notes
Block Type Id	int	ID of one of the block types described in the next section
Block Size	int	Number of bytes in the Data section
Data	byte array	Data - "block size" bytes

Block Types

Block Type 1 - File Version

Data will contain n ascii bytes to make a string

Block Type 2 - Layer

Data	Type	Notes
Layer Index	int	Slice layer

Block Type 3 - Contours

These are the outer and inner most contours of the part.

	Data	Type	Notes
	Count	int	Number of contours
X	Type	int	0 - outside, 1 - inside, 2 - open
X	Points	int	Number of points in the contour
X	Point Data	byte array	x1,y1,x2,y2,x3,y3 ...

X Repeat count times - 1 per contour

Block Type 4 - Parameter Sets

	Data	Type	Notes
	Count	int	Number of Parameter Sets
X	Id	int	Unique identifier
X	Type	int	1 - fill, 2 - contour, more to come
X	Laser Power	int	Watts (w)
X	Laser Speed	float	meters per second (m/s)

X Repeat count times - 1 per parameter set

Block Type 5 - Scan Lines

Data	Type	Notes
Count	int	Number of scan lines
Parameter Set Id	int	Id of parameter set associated with these scan lines
Rotation Angle	float	Rotation angle for fill type scan lines, -1 otherwise
Scan Area Id	int	Index of scan area, -1 if not applicable
Scan line data	byte array	(line1) x1,y1,x2,y2 (line2) x1,y1,x2,y2 ...
