UPPORTED FILE TYPES
The program supports a wide range of file types. Several important types
have been added in OmniPage Pro 11.
File types for opening and saving images
Input image files can have resolutions up to 600 dpi, but 300 dpi (both
horizontally and vertically) is recommended for optimum OCR accuracy.
The program stores black-and-white images at their original resolution,
but grayscale and color images are not usually saved above 150 dpi.
Hover the cursor over an image for a popup window showing the size and
resolution of the original image.
