Image processing options

ABBYY PDF Transformer+ offers multiple image processing options, which may improve the quality

of source images for accurate optical character recognition.

Be sure to select the appropriate image processing options when scanning paper documents or

creating PDFs from image files.

 Recognize text — Selecting this option will place a text layer under the image, producing a

searchable PDF document that looks exactly like the original. You will be able to copy and mark up

text in the PDF document.

 Correct distorted text lines, document skew, and other defects — Selecting this option will

cause the program to run a number of image enhancement routines on your images.

Depending on the type of an input image, ABBYY PDF Transformer+ will select the appropriate

image enhancement mechanism, such as skew correction, correction of trapezium distortions, or

adjustment of image resolution.

Image enhancement may take some time.

 Correct page orientation — Selecting this option will cause the program to detect the orientation

of the page on the scanner.

For best recognition results, a page should have the standard orientation, i.e. with horizontal lines

and letters pointing upwards.

 Split facing pages — Selecting this option will cause the problem to split any two pages of a book

or magazine spread into two separate images.

When you scan a book, a scanned image will typically contain two opposite pages. For best

recognition results, the program will split the image into two, creating a separate PDF page for each

book page.

This feature will not work on Chinese and Japanese texts.

 Use mixed raster content (MRC) compression — Selecting this option will apply the MRC

compression algorithm, which greatly reduces file size and preserves the visual quality the image.

Make sure that the right text recognition languages are selected.
