I get a 'Filetype Codec needed to use this feature' error message. How can I fix it?

The issue you're experiencing is due to a missing file filter in your application. LEADTOOLS uses a variety of codecs for opening files depending on the file format. These codec files, which have the signature Leadtool.Codecs.???.dll (where ??? is the typical extension for files which can be opened with the filter--this is not always the case, as the codec for JPG files is actually CMP, for example) must reside in your application's output folder. It is not necessary to reference them directly in your application; manually copying them is sufficent.

For more information on which files are necessary depending on the needs of your application, see our documentation on "Files to be Included With Your Application".
