Method Documentation

◆ generateBitmap:format:unit_width:height:level:()

- (FSBitmap *) generateBitmap: (NSString *)  info
format: (FSBarcodeFormat format
unit_width: (int)  unit_width
height: (int)  height
level: (FSBarcodeQRErrorCorrectionLevel level 

Generate a barcode bitmap with a given information string and specified barcode format.

Parameters
[in]infoInformation string to be encoded to barcode bitmap. It should not be an empty string.
[in]formatBarcode format which is used to encode information string. Please refer to values starting from FSBarcodeFormatCode39 and this should be one of these values.
[in]unit_widthUnit width for barcode, in pixels. Valid values: from 1 to 5. If input value is below 1, 1 will be used by default; if input value is above 5, 5 will be used by default.
The width of the bitmap will be equal to the product of this parameter and the width of the info encoding. Specially, for PDF-417 and QR Code, height will be ignored, and the height of bitmap will be equal to the product of this parameter and the height of the info encoding.
[in]heightThe height for bitmap, in pixels. Valid values: equal to or above 20. If input value is below 20, 20 will be used by default.
Specially, for PDF-417 and QR Code, height will be ignored, and the height of bitmap will be equal to the product of unit_width and the height of the info encoding.
[in]level(Required only for QR Code) Error correction level. Please refer to values starting from FSBarcodeQRCorrectionLevelLow and this should be one of these values.
Returns
A barcode bitmap.

◆ initWithOther:()

- (id) initWithOther: (FSBarcode*)  other

Constructor, with another barcode object.

Parameters
[in]otherAnother barcode object.

◆ isEmpty()

- (BOOL) isEmpty

Check whether current object is empty or not.

When the current object is empty, that means current object is useless.
