Example

This example method can be used in creating an "curveType" mentioned in the ICC.1:2004-10 specification

Visual BasicCopy Code
Public Sub IccCurveTagTypeExample()
   ' load an Icc Profile
   Dim iccProfile As New IccProfileExtended("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\EmptyIcc.icc")

   ' preparing curve data, it consists of domain and range values
   ' if we have 1 value, it should be in the u8Fixed8Number format,
   ' and if we have more than 1 value, their type should be uInt16Number (ushort),
   ' in this example we will use more than 1 value, look at the CS example
   ' 1 value curve data example
   ' for more information about domain and range values refere to
   ' ICC.1:2004-10 specification page 39.
   Dim myDoubleValue As Double = 1.5
   Dim curveData() As UShort = {1, 2, 3}

   ' in case of 1 value, the value should be in the u8Fixed8Number format, you can accomplish this by
   Dim dummyData As UShort = CType(IccTools.FromDoubleToU8Fixed8Number(myDoubleValue), UShort)

   ' to read the value back from the curve data use the following function
   myDoubleValue = IccTools.FromU8Fixed8NumberToDouble(dummyData)

   ' create the new iccCurveType
   Dim iccCurve As New IccCurve(curveData)

   ' define the tag type
   Dim iccCurveTagType As New IccCurveTagType(iccCurve)

   ' insert the new tag type into the Icc Profile
   iccProfile.AddTag(iccCurveTagType, IccTag.GrayTRCTag, IccTagTypeBase.CurveTypeSignature)

   ' generate the new profile id
   iccProfile.GenerateProfileId()

   ' update the icc array with the new changes
   iccProfile.UpdateDataArray()

   ' write the Icc Profile into a new file
   iccProfile.GenerateIccFile("C:\Program Files\LEAD Technologies\LEADTOOLS 15\Images\IccCurveTagTypeVB.icc")
End Sub
