OmniPage OCR

Properties panel

• DisplayName - The display name of the activity.

• Image - The image that you want to process. This field supports only Image variables.

• Private - If selected, the values of variables and arguments are no longer logged at Verbose level.

• EnginePack - Specifies which embedded engine must be used for image processing. There are two options, as follows: Basic - Supports a wide range of languages, Extended - Contains extra support for Asian, Arabic, Thai, Hebrew and Vietnamese languages. Check the list of all available languages for the Basic pack at the end of this page.
  Note: In order to use the Extended engine, you must manually install the UiPath.OmniPage.Bundle.Extended package in the current project from the Package Manager.
• ExtractWords - If selected, extracts the on-screen position of all detected words.
• Language - The language used by the OCR engine. The default option is auto, meaning that the language is automatically detected. Multiple languages can be used separated by commas.
  Note:

  You can use settings for multiple languages at the same time. For example, you can set "eng,fra" to process images that contain both English as well as French content.

  Note that Japanese, Korean, and Chinese language settings call up a dedicated recognition engine. Only one of these languages should be selected at a time and not combined with any non-Asian language.

  Short embedded texts in English can be recognized without English being selected as a recognition language.

• Profile - Choose a pre-processing profile for the specified image or UI element to achieve a better OCR read. The following options are available:
  • None - does not apply a pre-processing profile, this is the default option;
  • Screen - pre-processing suitable for remote desktop applications;
  • Scan - pre-processing suitable for scanned files;
  • Legacy - uses the engine's default settings for pre-processing images.
• Scale - The scaling factor of the selected UI element or image. The higher the number is, the more you enlarge the image. This can provide a better OCR read and it is recommended with small images. If you want to scale down, values between 0 and 1 are also accepted. By default, the value is 1.
  Note: If you want to use this OCR activity from package UiPath.OmniPage.Activities v1.8.0 in Studio v19.10, install the UiPath.CoreIPC package, version 2.0.1 or higher.
  Important: Large-size images may result in an error when the scaling factor is higher than 1.

• Result - The text extracted by the OCR engine along with their on-screen position, stored in a KeyValuePair<Rectangle,String>. This field supports only KeyValuePair<Rectangle,String>.
• Text - The text extracted by the OCR engine, stored in a String variable. This field supports only String variables.
