I want to convert a jpg to a tif file with LEADTOOLS 15.

When I use the following code a get an exception:

  Message="Feature not supported"
       bei Leadtools.RasterException.CheckErrorCode(Int32 code)
       bei Leadtools.Codecs.RasterCodecs.SaveOnePage(Int32 page, SaveParams saveParams)
       bei Leadtools.Codecs.RasterCodecs.DoSave(SaveParams saveParams)
       bei Leadtools.Codecs.RasterCodecs.Save(RasterImage image, String fileName, RasterImageFormat format, Int32 bitsPerPixel)

How can I create a tif file from a jpg file without errors?


Imports System

Imports System.Windows
Imports System.Windows.Forms
Imports Leadtools
Imports Leadtools.Codecs

Public Class Form1

    Private codecs As RasterCodecs
    Private image As RasterImage

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load


        codecs = New RasterCodecs
        Dim Filename As String = "C:\hello.jpg"

        image = New RasterImage(System.Drawing.Image.FromFile(Filename))

        Dim NewFilename As String = "C:\hello.tif"
        codecs.Save(image, NewFilename, Leadtools.RasterImageFormat.CcittGroup4, 1)

    End Sub
End Class

In most cases, the reason for this error is the absence of
LEADTOOLS codec DLL files, such as "Leadtools.Codecs.Cmp.dll" needed
for loading and saving CMP and JPEG files. Also, Leadtools.Codecs.Tif.dll and Leadtools.Codecs.Fax.dll are needed for loading and saving Tiff image files.
The needed codecs must be in the application path.
Adding them to the references ensures they're copied to the EXE's folder.
