Mac EAN 13 Barcode Generator SDK

Generating & Printing EAN-13 Barcodes in Mac OS



Index
An EAN-13 barcode (originally European Article Number) is a barcoding standard which is a superset of the original 12-digit Universal Product Code (UPC) system developed in the United States. The EAN-13 barcode is defined by the standards organisation GS1. The numbers encoded in EAN-13 bar codes are product identification numbers which are called Japanese Article Number (JAN) in Japan. All the numbers encoded in UPC and EAN barcodes are known as Global Trade Item Numbers (GTIN), and they can be encoded in other GS1 barcodes.
Mac Barcode EAN13 supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  1. Create a barcode object
  2. Set barcode properties
  3. call drawWithView() method, to paint barcode on the canvas.

Sample Code:
- (void)drawRect:(CGRect)rect {
    // Drawing code
    
    OBLinear *pLinear = [OBLinear new];
    [pLinear setNBarcodeType: OB_CODE128A];
    [pLinear setPDataMsg: [[NSString alloc] initWithString: (@"AB")]];
    //[pLinear setPSupData: [[NSString alloc] initWithString: (@"14562")]];
    [pLinear setFX: USER_DEF_BAR_WIDTH];
    [pLinear setFY: USER_DEF_BAR_HEIGHT];
    
    [pLinear setFLeftMargin: (USER_DEF_LEFT_MARGIN)];
    [pLinear setFRightMargin: (USER_DEF_RIGHT_MARGIN)];
    [pLinear setFTopMargin: (USER_DEF_TOP_MARGIN)];
    [pLinear setFBottomMargin: (USER_DEF_BOTTOM_MARGIN)];
    
    [pLinear setNRotate: (OB_Rotate0)];
    
    UIFont *pTextFont = [UIFont fontWithName: @"Arial" size: 8.0f];
    [pLinear setPTextFont: pTextFont];
    
    [pLinear drawWithView: (self)];
    [pLinear release];
    
}

Category Class Properties Default Comments
Basic nBarcodeType OB_EAN13 (15) OBBarcodeType. Barcode type.
OB_EAN13 = 15,
OB_EAN13_2 = 16,
OB_EAN13_5 = 17.
pDataMsg "" NSString. Barcode data value to encode. Valid barcode data size is 12 digits (without last checksum digits, our Mac barcode library will calculate for you).
bAddCheckSum true BOOL. AddCheckSum property is not applied here. Mac Barcode will always add a check character in the last digit (modulo 10).
 
UPC/EAN Related pSupData "" NSString. Set the sData property with the supplementary data to encode.
fSupHeight 0.8 float. This is a multiplicator of the height of the code; The default is 0.8 (80%).
fSupSpace 0 float. The separation between the barcode and the supplement
 
Size Related uom 0 Unit of meature for all size related setting in the library.
0: pixel; 1: cm; 2: inch.
fX 1 width of barcode module (narrow bar), default is 1 pixel
fY 30 barcode module height, default is 30 pixel
fBarcodeWidth 0 generted barcode image width
fBarcodeHeight 0 generted barcode image height
fLeftMargin 0 image left margin

nRotate 0 OBRotate. Valid values:
OB_Rotate0 = 0,
OB_Rotate90 = 1,
OB_Rotate180 = 2,
OB_Rotate270 = 3
