CIFilter.Generator.AztecCode

struct AztecCode: CIFilterContainerProtocol

 Discussion
 Generates an output image representing the input data according to the ISO/IEC 24778:2008 standard. The width and height of each module (square dot) of the code in the output image is one pixel. To create an Aztec code from a string or URL, convert it to an NSData object using the NSISOLatin1StringEncoding string encoding. The output image also includes two pixels of padding on each side (for example, a 15 x 15 code creates a 19 x 19 image).

Available in OS X v10.10 and later and in iOS 8.0 and later.

Properties

filter

var filter: CIFilter

message

The data to be encoded as an Aztec code. An NSData object whose display name is Message.

var message: Data?

correctionLevel

The percentage of redundancy to add to the message data in the barcode encoding. A higher correction level allows a barcode to be correctly read even when partially damaged. An NSNumber object whose display name is CorrectionLevel. Default value: 23.00 Minimum: 5.00 Maximum: 95.00 Slider minimum: 5.00 Slider maximum: 95.00 Identity: 0.00

var correctionLevel: NSNumber

layers

The number of concentric squares (with a width of two pixels each) encoding the barcode data. When this parameter is set to zero, Core Image automatically determines the appropriate number of layers to encode the message at the specified correction level. An NSNumber object whose display name is Layers. Default value: 0.00 Minimum: 1.00 Maximum: 32.00 Slider minimum: 1.00 Slider maximum: 32.00 Identity: 0.00

var layers: NSNumber

compactStyle

A Boolean value that determines whether to use the compact or full-size Aztec barcode format. The compact format can store up to 44 bytes of message data (including data added for correction) in up to 4 layers, producing a barcode image sized between 15 x 15 and 27 x 27 pixels. The full-size format can store up to 1914 bytes of message data (including correction) in up to 32 layers, producing a barcode image sized no larger than 151 x 151 pixels. An NSNumber object whose display name is CompactStyle. Default value: 0.00 Minimum: 0.00 Maximum: 1.00 Slider minimum: 0.00 Slider maximum: 1.00 Identity: 0.00
