Hello!
I have the same situation in the LEADTOOLS v17

Could I ask you why errors rise in the next code:

RasterSupport.Unlock(RasterSupportType.Document, "...");
RasterCodecs _codecs = new RasterCodecs();

_codecs.Save(e.Image, _fileName, RasterImageFormat.RasPdf, 1, 1, 1, 1, CodecsSavePageMode.Append);

Error - "PDF capability is required":

at Leadtools.RasterException.CheckErrorCode(Int32 code)
at Leadtools.Codecs.RasterCodecs.SaveOnePage(Int32 page, SaveParams saveParams)
at Leadtools.Codecs.RasterCodecs.DoSave(SaveParams saveParams)
at Leadtools.Codecs.RasterCodecs.Save(RasterImage image, String fileName, RasterImageFormat format, Int32 bitsPerPixel, Int32 firstPage, Int32 lastPage, Int32 firstSavePageNumber, CodecsSavePageMode pageMode)
at NordicIT.Mark5.Doc.Scanner.MarkScanner._twainSession_AcquirePage(Object sender, TwainAcquirePageEventArgs e)

or:

_codecs.Save(e.Image, _fileName, RasterImageFormat.PdfLeadMrc, 1, 1, 1, 1, CodecsSavePageMode.Append);

Error - "Feature not supported":

at Leadtools.RasterException.CheckErrorCode(Int32 code)
at Leadtools.Codecs.RasterCodecs.SaveOnePage(Int32 page, SaveParams saveParams)
at Leadtools.Codecs.RasterCodecs.DoSave(SaveParams saveParams)
at Leadtools.Codecs.RasterCodecs.Save(RasterImage image, String fileName, RasterImageFormat format, Int32 bitsPerPixel, Int32 firstPage, Int32 lastPage, Int32 firstSavePageNumber, CodecsSavePageMode pageMode)
at NordicIT.Mark5.Doc.Scanner.MarkScanner._twainSession_AcquirePage(Object sender, TwainAcquirePageEventArgs e)


References added on:
Leadtools.dll
Leadtools.Codecs.dll
Leadtools.Twain.dll
Leadtools.Codecs.Pdf.dll
Leadtools.Codecs.Ras.dll
And some other dll-s

Thank you for answers!

Our moderator split your post from the thread it was in, because having the same error does not always mean it's the same problem.

Are you using version 17.0? If yes, the "PDF capability is required" error means that to save to PDF format, you have to unlock the PDF save support in your code using the RasterSupport.Unlock Method.
If you have the LEADTOOLS PDF Plug-in but you don't have the unlock keys, please send your LEADTOOLS v17 serial numbers in a new email to sales@leadtools.com and ask about the PDF save unlock key.

About the "Feature not supported" issue, the problem might be related to missing filter DLLs in your project. According to the documentation, you need to add the following DLLs as references in your project to save PdfLeadMrc format:
+----------------+
Leadtools.Mrc.dll
Leadtools.PdfCompressor.dll
Leadtools.Pdf.dll
Leadtools.Codecs.Cmp.dll
Leadtools.Codecs.Jb2.dll
Leadtools.Codecs.Raw.dll
Leadtools.Codecs.Fax.dll
+----------------+

For more information, please see the help topic "Files To Be Included With Your Application" in the LEADTOOLS .Net help file.

If the problem persists after adding the DLLs, please send this issue in a new email to support@leadtools.com and include the following information in your email:
1. Your LEADTOOLS serial number (do NOT post it here).
2. A link to this forum post.
