BarcodeAlignment Enumeration (original) (raw)
Summary
Horizontal or vertical alignment to use when writing barcodes.

[SerializableAttribute()]
public enum BarcodeAlignment
typedef NS_ENUM(NSInteger, LTBarcodeAlignment) {
LTBarcodeAlignmentNear,

LTBarcodeAlignmentFar

public enum BarcodeAlignment [SerializableAttribute()]
public enum class BarcodeAlignment
class BarcodeAlignment(Enum):
Near = 0
Center = 1
Far = 2
Members
| Value | Member | Description |
|---|---|---|
| 0 | Near | Aligns the barcode to the near edge of BarcodeData.Bounds. This is the left edge (LeadRect.Left) when this is a horizontal alignment or the top edge (LeadRect.Top) when this is a vertical alignment. The barcode actual width or height is not used. |
| 1 | Center | Aligns the barcode to the center BarcodeData.Bounds. This is horizontal center (LeadRect.Left + (LeadRect.Width - "barcodeWidth") / 2) when this is a horizontal alignment or the vertical center (LeadRect.Top + (LeadRect.Height - "barcodeHeight") / 2) when this is a vertical alignment. |
| 2 | Far | Aligns the barcode to the far edge of BarcodeData.Bounds. This is the left edge (LeadRect.Right - "barcodeWidth") if this is a horizontal alignment or the top edge (LeadRect.Bottom - "barcodeHeight") if this is a vertical alignment. |
Example
This example uses BarcodeAlignment to write a QR barcode at the 9 locations that can be set by changing the alignment. These locations are top/left, top/center, top/right, center/left, center/center, center/right, bottom/left, bottom/center and bottom/right.
