Detailed Description

Barcodes are generated through layout->barcodeTool, a barcodeModule, and are added to the current cell on the activeLayer. First choose an encoding such as setCode128, setCode39, setDatamatrix or setQrCode; some codes ignore characters they cannot encode. Then enter two points with layout->drawing->point so addBarcode knows the rectangle, or set the data property and call placeBarcode with two point corners. ratio is the wide-to-narrow bar ratio for codes that allow it; changing the encoding resets ratio to its default. The example below places a Code 128 symbol; Data Matrix, Micro-QR and QR each have a picture under their set method.

Example:

layout->barcodeTool->setCode128();
layout->drawing->point(1400,-800);
layout->drawing->point(8800,-3300);
layout->barcodeTool->addBarcode("LayoutEditor");

That call produces this barcode:

Member Function Documentation

void barcodeModule::addBarcode(string text)

Adds a barcode with payload text to the current cell on the activeLayer. Enter the two corners first with layout->drawing->point. Characters the current encoding cannot represent are ignored.

string barcodeModule::data

Payload used by placeBarcode. Set this before you call placeBarcode.

void barcodeModule::placeBarcode(point p1,point p2)

Places a barcode in the rectangle from p1 to p2 using the data property instead of addBarcode.

double barcodeModule::ratio

Wide-to-narrow bar ratio for encodings that allow it. Set ratio after the encoding. Changing the encoding restores the default.

void barcodeModule::setCode128()

Uses Code 128 and picks subset A, B or C to match the text.

void barcodeModule::setCode128A()

Uses Code 128A: capital letters, digits and most special characters, including newline and return.

void barcodeModule::setCode128B()

Uses Code 128B: letters, digits and some special characters, not newline or return.

void barcodeModule::setCode128C()

Uses Code 128C: digits only.

void barcodeModule::setCode39()

Uses Code 39: 42 characters (capitals, digits and a few specials). Each character is nine bars or spaces with three wide.

void barcodeModule::setCode39Mod43()

Uses Code 39 with a Mod 43 checksum byte at the end.

void barcodeModule::setDatamatrix()

Sets the barcode encoding to datamatrix (ISO16022). The entered text will be ASCII encoded to the datamatrix.

These special phrases are available:

Intended use of these special phrases is to enter GS1 DataMatrix ECC200 code, which is an open system for automatic identification. (e.g. 17091125 marks an expiration date of 25th Nov. 2009, or 21AB12345 marks a serial number of AB12345).

Datametrix Example:

void barcodeModule::setMicroQrCode()

Sets the barcode encoding to mirco QR-code. The entered text will be stored as 8 bit unicode data. The maximum length is 15 character.

Micro-QR Example:

void barcodeModule::setQrCode()

Sets the barcode encoding to QR-code (ISO18004). The entered text will be stored as 8 bit unicode data.
