Previewing Images
If desired, you can use the preview process to scan a sample image to ensure that it
meets your quality requirements and to validate the settings in the current profile. If
necessary, you can make adjustments to the profile. If your scanner supports
advanced features, you can use the preview process to test settings such as color
dropout, JPEG compression, etc. Use the Preview feature before you scan a batch of
documents, or to adjust the settings between batches.
When you select Preview, VRS opens the most recently scanned image in the VRS
Interactive Viewer. For this reason, the Preview function is available only if a scanned
image exists in the VRS cache (if you are using VRS with a production class scanner,
the last image may not be available). As you apply property changes from the VRS
Interactive Viewer, the preview image is refreshed so you can evaluate the impact of
the adjustments. Be aware that the changes to the preview image are not sent to your
scanning application; the image is intended only for preview purposes. You can
invoke the preview process by selecting the following:
• Preview from the VRS taskbar menu.
• First Page from the QC Modes menu.
• Preview check box from the TWAIN scanning interface.
• First Page from the QC Modes menu.
• Preview check box from the TWAIN scanning interface.

image properties, refer to Using the VRS Adjustment Controls on page 64.
