__NOTOC__

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

===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.

===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.

__NOTOC__

== The GSD binary file format ==
This is my first try to reverse engineer a binary file format. If you like, you could add your thoughts!
By comparison between different files with the extention .gsd i try to see what data is stored where. It has some parts in ansi-text and the most parts are just binary numbers of different length. As identification, the file starts with the text "GRAPHTEC PRT&CUT". The next line at offset 0000:0010 starts with binary numbers "03 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00" (I don't know if they make any sense there).

* From offset 0000:0080 to offset 0000:00cf is unknown binary data.
* From offset 0000:00d3 to offset 0000:00de is binary data, which is exactly repeated from offset 0000:00fb to 0000:0107. It starts with the hex numbers 40 6a 40 which seems to be a marker for file seek. It ends with 40 00 04. Inbetween those bytes is data which funktion is still unknown.

* Every object can have a different color in the 8bit-RGB-color-range. E.g. RGB(254,254,254), but most probably it is only black. RGB(0,0,0).

* The size of the canvas is written in pure ansi text. The value could be "ISO A4" or "Letter".

* The hex value 40 seems to be the delimiter between chunks of data of different length. Hex value ff ff ff semms to be a start delimiter and ff ff ff ff semms to be the end delimiter.

=== Footer ===
The footer is composed of blocks of data. Each block begins with a 2-byte code indicating the type of data, followed by 1 byte code indicating the datatype and a second 1 byte code indicating how many elements of data are stored.
====Header====
54 bytes - unknown data

====Blocks====
The first two bytes of the block provide information on the purpose of the block. 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" indicates the incorrect length.

__NOTOC__

== The GSD binary file format ==
This is my first try to reverse engineer a binary file format. If you like, you could add your thoughts!
By comparison between different files with the extention .gsd i try to see what data is stored where. It has some parts in ansi-text and the most parts are just binary numbers of different length. As identification, the file starts with the text "GRAPHTEC PRT&CUT". The next line at offset 0000:0010 starts with binary numbers "03 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00" (I don't know if they make any sense there).

* From offset 0000:0080 to offset 0000:00cf is unknown binary data.
* From offset 0000:00d3 to offset 0000:00de is binary data, which is exactly repeated from offset 0000:00fb to 0000:0107. It starts with the hex numbers 40 6a 40 which seems to be a marker for file seek. It ends with 40 00 04. Inbetween those bytes is data which funktion is still unknown.

* Every object can have a different color in the 8bit-RGB-color-range. E.g. RGB(254,254,254), but most probably it is only black. RGB(0,0,0).

* The size of the canvas is written in pure ansi text. The value could be "ISO A4" or "Letter".

* The hex value 40 seems to be the delimiter between chunks of data of different length. Hex value ff ff ff semms to be a start delimiter and ff ff ff ff semms to be the end delimiter.

=== Footer ===
The footer is composed of blocks of data. Each block begins with a 2-byte code indicating the type of data, followed by 1 byte code indicating the datatype and a second 1 byte code indicating how many elements of data are stored.
====Header====
54 bytes - unknown data

====Blocks====
The first two bytes of the block provide information on the purpose of the block. 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" indicates the incorrect length.

By comparison between different files with the extention .gsd i try to see what data is stored where. It has some parts in ansi-text and the most parts are just binary numbers of different length. As identification, the file starts with the text "GRAPHTEC PRT&CUT". The next line at offset 0000:0010 starts with binary numbers "03 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00" (I don't know if they make any sense there).

* From offset 0000:0080 to offset 0000:00cf is unknown binary data.
* From offset 0000:00d3 to offset 0000:00de is binary data, which is exactly repeated from offset 0000:00fb to 0000:0107. It starts with the hex numbers 40 6a 40 which seems to be a marker for file seek. It ends with 40 00 04. Inbetween those bytes is data which funktion is still unknown.

* Every object can have a different color in the 8bit-RGB-color-range. E.g. RGB(254,254,254), but most probably it is only black. RGB(0,0,0).

* The size of the canvas is written in pure ansi text. The value could be "ISO A4" or "Letter".

* The hex value 40 seems to be the delimiter between chunks of data of different length. Hex value ff ff ff semms to be a start delimiter and ff ff ff ff semms to be the end delimiter.

=== Footer ===
The footer is composed of blocks of data. Each block begins with a 2-byte code indicating the type of data, followed by 1 byte code indicating the datatype and a second 1 byte code indicating how many elements of data are stored.
====Header====
54 bytes - unknown data

====Blocks====
The first two bytes of the block provide information on the purpose of the block. The following 2 bytes indicate the type of data and the number of data elements of that type.

== The GSD binary file format ==
This is my first try to reverse engineer a binary file format. If you like, you could add your thoughts!
By comparison between different files with the extention .gsd i try to see what data is stored where. It has some parts in ansi-text and the most parts are just binary numbers of different length. As identification, the file starts with the text "GRAPHTEC PRT&CUT". The next line at offset 0000:0010 starts with binary numbers "03 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00" (I don't know if they make any sense there).

* From offset 0000:0080 to offset 0000:00cf is unknown binary data.
* From offset 0000:00d3 to offset 0000:00de is binary data, which is exactly repeated from offset 0000:00fb to 0000:0107. It starts with the hex numbers 40 6a 40 which seems to be a marker for file seek. It ends with 40 00 04. Inbetween those bytes is data which funktion is still unknown.
