Generate a barcode bitmap with a given information string and specified barcode format.
| [in] | info | Information string to be encoded to barcode bitmap. It should not be an empty string. |
| [in] | format | Barcode 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_width | Unit 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] | height | The 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. |
| - (id) initWithOther: | (FSBarcode*) | other |
Constructor, with another barcode object.
| [in] | other | Another barcode object. |
| - (BOOL) isEmpty |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
