2. Select a tool and make the desired changes. Most of the tools can be applied to selected

pages or to all pages in the document. You can select pages using the Selection drop–

down list or in the Pages window.

3. Click the Exit Image Editor button after you are done editing the image.

The image editor contains the following tools:

 Recommended Preprocessing The program automatically determines which

adjustments need to be made to the image. Adjustments that may be applied include noise

and blur removal, color inversion to make the background color light, skew correction,

straightening of text lines, correction of trapezoidal distortion, and trimming of image

borders.

 Deskew Corrects image skew.

 Straighten Text Lines Straightens any curved text lines on the image.

 Photo Correction Tools in this group let you straighten text lines, remove noise and blur,

and turn the document's background color into white.

 Correct Trapezoid Distortion Corrects trapezoidal distortions and removes image edges

that don't contain any useful data. When this tool is selected, a blue grid appears on the

image. Drag the grid's corners to the corners of the image. If you do this correctly, the

grid's horizontal lines will be parallel to the text lines. Now click the Correct button.

 Rotate & Flip Tools in this group let you rotate images and flip them vertically or

horizontally to get the text on the image facing in the right direction.

 Split Tools in this group let you split the image into parts. This can be helpful if you are

scanning a book and need to split facing pages.

 Crop Removes image edges that don't contain any useful information.

 Invert Inverts image colors. This can be useful if you're dealing with non–standard text

coloring (light text on a dark background).

 Resolution Changes image resolution.

 Brightness & Contrast Changes the brightness and contrast of the image.

 Levels This tool lets you adjust the color levels of the images by changing the intensity of

shadows, light, and halftones.

To raise the contrast of an image, move the left and right sliders on the Input levels

histogram. The left slider sets the color that will be considered to be the blackest part of

the image, and the right slider sets the color that will be considered to be the whitest part

of the image. Moving the middle slider to the right will darken the image, and moving it to

the left will lighten the image.

Adjust the output level slider to decrease the contrast of the image.

 Eraser Removes a part of the image.

 Remove Color Marks Removes any color stamps and marks made in pen to facilitate the

recognition of the text obscured by such marks. This tool is designed for scanned

documents with dark text on a white background. Do not use this tool for digital photos

and documents with color backgrounds.
