• PadLeft - Calculate a Left Padding value to horizontally align a database image to center or right. To align right change CenterImage parameter to False.

  Code Block
  PadLeft(imgBytes As Byte(), cellWidth As Double, cellHeight As Double, Optional UnitOfMeasure As String = "in", Optional CenterImage As Boolean = True) As String

• PadTop - Calculate a Top Padding value to vertically align a database image to center or bottom. To align bottom change CenterImage parameter to False.

  Code Block
  PadTop(imgBytes As Byte(), cellWidth As Double, cellHeight As Double, Optional UnitOfMeasure As String = "in", Optional CenterImage As Boolean = True) As String

• QRCode - Generate a QRCode image as a byte array to display in an Image object.

  Code Block
  QRCode(content As String, size As Integer, Optional logofilepath As String = "", Optional IsURL As Boolean = False, Optional darkcolor As String = "", Optional lightcolor As String = "") As Byte()

  The following overload accepts a logo image in a byte array instead of a logo filepath

  Code Block
  QRCode(content As String, size As Integer, logobytes As Byte(), Optional IsURL As Boolean = False, Optional darkcolor As String = "", Optional lightcolor As String = "") As Byte()

  See the following explanation for each of the arguments

  • content = Text content of the QRCode

  • size = Size of image in pixels. 20 is the recommended size, large Pixels per module. Large values here can cause out-of-memory errors from the report viewer.

  • logofilepath = Filepath to a logo to embed in the center of the QR Code (example: C:\\myimage.png)

  • logobytes = Byte array of logo to embed in the center of the QR Code. This can be an image field from a dataset (example: Fields!Logo.Value)

  • IsURL = True if the content is a web URL to format the QR Code as a URL Payload

  • darkcolor = Dark color in the QR Code (examples: “black”, “255,255,255”)

  • lightcolor = Light color in the QR Code (examples: “white”, “0,0,0”)

  • Example

    • Expression (Value property on an Image with Source set to Database)

      Code Block
      language none
      =Code.QRCode("www.crowsnestsoftware.com", 20, "", True, "Red", "White")

    • Code

      Code Block
      language none
      Function QRCode(content as String, size as Integer, logobytes as Byte(), Optional IsUrl as Boolean = False, Optional darkcolor as String = "", Optional lightcolor as String = "") Return CrowsNest.Reporting.Images.QRCode(content, size, logobytes, IsURL, darkcolor, lightcolor) End Function
