The GSD binary file format

The file must begin with . This is a header to verify that it is the correct file type.

Header

0x00-0x0f "GRAPHTEC PRT&CUT"
0x10-0x17 0x06 00 00 00 01 00 00 00 00
0x18-0x7f This entire block is padded with zeros. There may be some other information stored, but in every sample file examined the data is simply 0.

Body

The body consists of a number of blocks of data. Every block starts with a length chunk indicating how many chunks are contained within that block. For more complex data such as the actual lines, polylines, and pen information chunks may contain entire blocks in a hierarchy.

Chunks

The first two bytes of the chunk provide information on the purpos. The following 2 bytes indicate the type of data and the number of data elements of that type.

While the data typically follows this pattern, in some cases (most notably distance measurements) the "datatype" may indicate a different length than is actually used.

Header Description
00 1 byte of data stored in length byte
01 1-byte little endian 8-bit integer. Typically used for boolean values.
02 2-byte little endian 16-bit integer
03 4-byte little endian 32-bit integer
04 8-byte little endian double precision float. Usually for storing a distance in mm units
05 ASCII data chunks

Based on several files generated using version 5.10 of the QuicKutz ROBO Master software, the following information has been deduced. In some cases the data observed in a given chunk is provided where the purpose is unknown.
