No scan preview in ICA; immediately creates image in Pictures folder



Hi,

  I am working on an ICA module for a scanner but
after I launch Image Capture and it finishes scanning,
the app will not display a preview of the image that I
just scanned. 

  First, I launch a scan driver via ICA. This scan
driver generates a tiff file which is saved at /tmp
directory. I then open this file, get the image data
and place it into a buffer which would then be
accessed by
ICDScannerInitiateNotificationCallbackWithData. But
nothing happens. ICA overview pane is blank.
  
  What's weird is that ICA automatically generates a
tiff or jpeg image of the image that i scanned and
saves it in my Pictures directory. Even if I am just
trying to preview the image, ICD_ScannerReadFileData
gets called.

   I hope someone can help me with my problem.

Thanks!
