# Image preprocessing

> Covers automatic image preprocessing for receipts in FlexiCapture for Invoices — photo cropping, line straightening, scan deskewing — and how to store original images.

When you feed a receipt to FlexiCapture for Invoices, the program determines whether the image is a photo or a scan and selects the image preprocessing operations appropriate for each type of image. For example, photos will be automatically cropped and their text lines will be straightened, as this will help the program to detect the fields more reliably. Scans, on the other hand, will be deskewed for the same purpose.

<Warning>
  The program will not be able to capture data from images containing multiple receipts scanned or shot together. Before feeding such images to the program, you will need to split them using the **Split** tool on the image editing toolbar, making sure that each image contains only one receipt.
</Warning>

## Store and view the original image

To preview the original image, select the **Store original image during processing** option in one of these locations:

* On the **Image Processing** tab of the **Project Properties** dialog box (prior to loading your images)
* In the image processing settings dialog box that is displayed when you create an image import profile
* In the image processing settings dialog box that is displayed when you load images manually

<Warning>
  If you choose to store the original images, your project will take up more memory and receipts will take longer to process. We recommend storing the original images only when absolutely necessary.
</Warning>

To view the original image, click **View → Image → Show Original Image**. Alternatively, right-click anywhere in the captured document and click **Show Original Image** on the shortcut menu.
