Mac Code 39 Barcode Generator SDK

Generating & Printing Code 39 Barcodes in Mac OS



Index
Code 39 (also known as "USS Code 39", "Code 3/9", "Code 3 of 9", "USD-3", "Alpha39", "Type 39") is a barcode symbology that can encode uppercase letters (A through Z), digits (0 through 9) and a handful of special characters like the $ sign.

Code 39 is restricted to 44 characters. In Full ASCII Code 39 Symbols 0-9, A-Z, "." ,and "-" are the same as their representations in Code 39. Lower case letters, additional punctuation characters and control characters are represented by sequences of two characters of Code 39.
Mac Barcode Code 39 supports:
  • 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • Uppercase letters (A - Z)
  • - (Dash), $ (Dollar), % (Percentage), (Space), . (Point), / (Slash), + (Plus)

Mac Barcode Code 39 Extension supports:
  • all 128 ASCII characters
  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];
    
}
