OCAD 11 Dateiformat

Version: 2012-02-09

Allgemein

Dies ist eine Beschreibung des Dateiformates von OCAD 11 Dateien.

Beachten Sie, dass dies ein internes Format ist und in zukünftigen Versionen ändern kann.

Verwendete Datentypen

OCAD ist in 32-bit Delphi programmiert und verwendet die Namen für Datentypen, wie sie in Delphi erscheinen. Die gleichen Datentypen sind aber in anderen Entwicklungssystemen wie C++ ebenfalls erhältlich.

Integer	32-bit signed integer
SmallInt	16-bit signed integer
Word	16-bit unsigned integer
WordBool	16-bit boolean
String[x]	Widestring. The first byte contains the number of characters followed by the characters. The string is not zero-terminated. Die maximale Anzahl Zeichen ist x. Der String besetzt x+1 bytes in der Datei.
Double	64-bit floating point number
TDPoly	Ein spezieller Datentyp (64-bit), der für alle Koodinaten und Texte verwendet wird. Er ist folgendermassen definiert: TDPoly = record x, y: integer; end; Die untersten 8 Bits werden für die Markierung von speziellen Punkten verwendet: Markierungen für die x-Koordinate: 1: Dieser Punkt ist der erste Punkt der Bézier-Kurve. 2: Dieser Punkt ist der zweite Punkt der Bézier-Kurve. 4: Für Doppellinien: there is no left line between this point and the next point 8: Dieser Punkt ist ein Flächenrandpunkt oder eine virtuelle Linienlücke. Markierungen für die y-Koordinate: 1: Dieser Punkt ist ein Eckpunkt. 2: Dieser Punkt ist der erste Punkt eines Loches in einer Fläche. 4: for double lines: there is no right line between this point and the next point 8: Dieser Punkt ist ein Strichelungspunkt The upper 24 bits contain the coordinate value measured in units of 0.01 mm.

Beachten Sie: Alle Dateipositionen sind vom Anfang der Datei an in Bytes.

Dateikopf

OCAD-Dateien beginnen mit einem Dateikopf.

Symbole

Jeder Symbolverzeichnis-Block enthält die die Position des nächsten Symbolverzeichnis-Blocks und die Dateipositionen von 256 Symbolen.

TSymbolIndexBlock= record        // Size: 1028 Bytes
  NextSymbolIndexBlock: integer;
  SymbolPosition: array[0..255] of integer;
end;

Basis-Symbol

Die verschiedenen Symboltypen werden in verschiedenen Strukturen definiert. Es gibt einen abstrakten Typ TBaseSym, welcher gemeinsame Felder für alle Symboltypen enthält. Dieser Typ wird für programmiertechnische Gründe verwendet, existiert jedoch nicht in OCAD-Dateien.

TBaseSym = packed record
  Size: integer;                // Grösse des Symboles in Bytes. Dies hängt vom Symboltyp ab. Koordinaten, die dem Symbol folgen sind ingegriffen.
  SymNum: integer;              // Symbolnummer. Dies ist 1000x die Symbolnummer.
                                // Beispiel:
                                //   203.145 wird als 203145 gespeichert
  Otp: byte;                    // Objekttyp

Falls mehrere Objekte vorhanden sind, folgen sich diese (nur die verwendeten Koordinaten werden gespeichert). Um die Anzahl Objekte festzulegen, muss die Variable DataSize verwendet werden.

Parameter Strings

The Parameter Strings contain all the information about the setup structure, background maps,course setting and database connection.

Similar to the symbols and objects there are String Index Blocks which contain the basic information for 256 Parameter Strings and the file position of the strings.

TStringIndexBlock contains the basic information for 256 strings

TStringIndexBlock = record
  NextIndexBlock: integer;            // file position of the next StringIndexBlock, 0 if this is the last StringIndexBlock
  Table: array[0..255] of TStringIndex;
end;

TStIndex contains the basic information for 1 string:

TStringIndex = packed record
  Pos: integer;                       // file position of string
  Len: integer;                       // length reversed for the string
  RecType: integer;                   // string typ number, if < 0 then deleted string
  ObjIndex: integer;                  // number of the object
end;

StringIndexBlk in the FileHeader points to the first StringIndexBlock.

The strings (null terminated) have the following structure:

• first field: all characters until the first tab (character 9). The first field can be missing (the string starts with a tab).
• tab (character 9)
• code: this is the first character after the tab
• value: all characters until the next tab
• tab
• code
• value
• ...

Some of String Types (number < 1000) may have multiple instances of the same type. They have to be stored as lists.
