DrawDataMatrixSymbolA
Vector graphics, Barcodes
Description
The trailing A denotes the ANSI (char) DLL entry point; the ActiveX/COM surface exposes only the Unicode form. Behaviour is identical to DrawDataMatrixSymbol and string arguments are interpreted using the current SetAnsiMode code page
This function draws a Data Matrix symbol onto the page. Data Matrix is a 2D barcode symbology allowing large amounts of data to be stored.
Syntax
Delphi
Function DLDrawDataMatrixSymbolA(InstanceID: Integer; Left, Top, ModuleSize: Double; Text: PAnsiChar; Encoding, SymbolSize, Options: Integer): Integer;DLL
int DLDrawDataMatrixSymbolA(int InstanceID, double Left, double Top, double ModuleSize, const char * Text, int Encoding, int SymbolSize, int Options);Parameters
| Left | The horizontal co-ordinate of the left edge of the symbol |
|---|---|
| Top | The vertical co-ordinate of the top edge of the symbol |
| ModuleSize | This value is used for the width and height of the dots which make up the symbol |
| Text | The text/data to store in the symbol |
| Encoding | 1 = ASCII encoding. See the Data Matrix specification for details. |
| SymbolSize | 0 = Auto size 1 = 10x10 2 = 12x12 3 = 8x18 4 = 14x14 5 = 8x32 6 = 16x16 7 = 12x26 8 = 18x18 9 = 20x20 10 = 12x36 11 = 22x22 12 = 16x36 13 = 24x24 14 = 26x26 15 = 16x48 16 = 32x32 17 = 36x36 18 = 40x40 19 = 44x44 20 = 48x48 21 = 52x52 22 = 64x64 23 = 72x72 24 = 80x80 25 = 88x88 26 = 96x96 27 = 104x104 28 = 120x120 29 = 132x132 0 = Normal 1 = Rotate 90 degrees counter clockwise 2 = Rotate 180 degrees 3 = Rotate 90 degrees clockwise Add 100 to for 1 unit quiet zone (white border) - (default) Add 200 to for 2 units quiet zone Add 300 to for 3 units quiet zone Add 400 to for 4 units quiet zone |
