Since ProScan builds on ImageEx technology, it is limited by any of the same limitations that ImageEx might have.

 

Currently the only (minor) limitation we would note is in regards to blob file storage.

 

The ImageEx code library has methods to read data about or load a single page of a multi page TIFF document directly from a Clarion blob file.  However it can not add a page, update a page or delete the page while the TIFF is stored in the blob.

 

ProScan takes care of this limitation by extracting the TIFF from the blob into a temporary file in the users TEMP folder (this is handled automatically by the templates).

 

Then the ProScan operations on the TIFF file are the same as they would be for an external file.

 

After the ProScan session the file is stored in the blob and the temporary files are deleted.
