Issues related to upgrade of Leadtools v14.5 to v17.5

Hello,

Our imaging solution product uses Leadtools v14.5 for dealing with images. We are in the process of upgrading our product with .net framework 4.0 support. That includes upgrade of Leadtools libraries to v17.5.
The following Leadtools libraries (dlls) are referred in our .net projects:
Leadtools
Leadtools.Codecs
Leadtools.Codecs.Cal
Leadtools.Codecs.Cmp
Leadtools.Codecs.Fax
Leadtools.Codecs.J2k
Leadtools.Codecs.Jb2
Leadtools.Codecs.Jbg
Leadtools.Codecs.Png
Leadtools.Codecs.Rtf
Leadtools.Codecs.Tif
Leadtools.Codecs.txt
Leadtools.Codecs.Wmp
Leadtools.ColorConversion
Leadtools.Kernel
Leadtools.Kernel.Codecs
Leadtools.Kernel.Codecs.Interfaces
Leadtools.WinForms
Leadtools.WinForms.CommonDialogs.Color
Leadtools.WinForms.CommonDialogs.File

In Leadtools v17.5, the below libraries are not available:
Leadtools.Codecs.Pdf.dll
Leadtools.Kernel.Codecs.dll
Leadtools.Kernel.dll
Leadtools.Kernel.Codecs.Interfaces.dll
Leadtools.Kernel.Ocr.dll
Leadtools.Ocr.dll

How we can solve the issues related to above libraries? Are these functionality moved to some libraries? Is there any documentation available to refer the changes from 14.5 to 17.5?

Hello,

I talked to you about this same issue in Live Chat this morning. When contacting Tech Support, please only use one form of communication when contacting us about specific issues. We ask this of all of our customers so that we can continue to provide the most efficient support possible. I am sure you can understand this.


My colleague, Ibrahim, has already posted some information here. Since upgrading is a common issue, I am posting the additional information I had sent to you in live chat for others to see as well.


When upgrade, I would recommend checking out our Version History :
http://www.leadtools.com/help/leadtools/v18/dh/to/leadtools.topics~leadtools.topics.version1changes.html

This would help with any code changes. I would recommend a text search in the old assembly for any classes, methods or properties that the compiler is having issues with. The version history lists any method that have changed, renamed or have been removed.

The OCR interface has been redesigned since 14.5. 
The new DLL would be Leadtools.Forms.Ocr.dll. Check out "Programming with Leadtools .NET OCR":

Here is a link to tutorials will also help you with the new interface:

If you have any further questions or concerns, please let us know.
