Loading image after migrating from v15 to v17 fails

Hi,

I migrated our software from LT v15 to v17. I changed all DLLs, LIBs and Header-files. Changes of the methods where not necessary (it compiled successfully). But unfortunately every time I try to load an image (L_LoadBitmap) I get the return code -9 (ERROR_FILE_FORMAT). I tried different files and formats. The same holds true for L_FileInfo(). It returns -9, too.

Is there anything more I need to change in version 17?

Thanks

Thomas

Thomas,
Error -9 means 'Invalid file format' and it is normally generated due to a missing DLL file which is required to load specific image format. For example, if you want to load JPEG file, you will need the Lfcmpu.dll.

If you try to load your files using our LEADTOOLS v17 Main CDLL demo, does it load them correctly? If yes and the problem only appears in your application, try to set your application Working Directory to the following folder:
[LEADTOOLS 17 v17]\Bin\CDLL\Win32

Thanks Adnan

It works now.  We copy the dlls into the applications working folder and I did not pay attention to the fact that the file format dlls are in the subfolder (“filters”). The application does not look for the dlls in this subfolder.

Due to this it is not a migration issue.
