Laserfiche Quick Fields allows you to configure image enhancements in two ways: as permanent enhancements, which will be saved as part of the image file itself, and as local enhancements, which are applied to the image for processing and then removed later. While permanent enhancements are useful for making the image more attractive and readable to the eye, local enhancements are good for changes that you do not wish to permanently save to the image, but that you want to apply to improve processes such as Zone OCR or Bar Code reading. For instance, you might want to remove a form from an image using Form Extractor to allow a Zone OCR process to more accurately read a section of the form, but you might still want the form to be visible in the image when you open the document in Laserfiche. For this, you would use a local image enhancement.

Local image enhancements are associated with one specific identification or process. For instance, if you configure a local image enhancement for one OmniPage Zone OCR process, the enhancement will only affect that Zone OCR; any other Zone OCR process will be unaffected. This allows you to configure exactly the local image enhancements you want for each process.

To apply a local image enhancement:

1. Create and configure an identification or image processing process, such as Bar Code or OmniPage Zone OCR.
2. Right-click the process and select Insert Local Image Enhancement. This will expand a menu with available image enhancements. Select the one you would like to add to this process.

   

   Note: You can also reach this menu by selecting the process, opening the Action menu, and selecting New Process and then Local Image Enhancement.

3. The local image enhancement will appear in the Session pane, under the process or identification to which you applied it. You can configure it normally in the Task pane.

   

   Note: Local image enhancements cannot be added to other image enhancement processes. If the Insert Local Image Enhancement command is unavailable when you select a process, make sure it is an identification or processing process, not an image enhancement.
