Tesseract OCR
UiPath.Core.Activities.GoogleOCR
Extracts a string and its information from an indicated UI element or image using Tesseract OCR Engine. It can be used with other OCR activities, such as Click OCR Text, Hover OCR Text, Double Click OCR Text, Get OCR Text, and Find OCR Text Position.
Before you run the Tesseract OCR Engine, install Visual C++ Redistributable x86 (32-bit) on the corresponding machine. Even if your operating system is 64-bit (x64), you still need to install the x86 (32-bit) version. Visit Visual C++ Redistributable latest supported downloads to select and install the version of Visual C++ that meets your requirements.
Options
- AllowedCharacters - The OCR engine extracts the given string according to the characters specified here.
- DeniedCharacters - The OCR engine extracts the given string without taking into account the characters specified here.
- Invert - If this check box is selected, the colors of the UI element are inverted before scraping. This is useful when the background is darker than the text color.
-
Language - The language used by the OCR engine to extract the string from the UI element. For the Google OCR engine, this field needs to contain the language file prefix, such as “ron” for Romanian, “ita” for Italian, and “fra” for French. You can find the supported language prefixes on this page.
Note: The language folder can be downloaded from here and added to your local folder%UserProfile%\.nuget\packages\uipath.vision\3.x.x\build\net461\tessdata. Once the language folder has been added locally, make sure to restart the UiPath Studio application. - ExtractWords - If this check box is selected, the on-screen position of each detected word is extracted.
- Profile - Choose a preprocessing profile for the specified image or UI element to achieve a better OCR read. The following options are available: None - does not apply a preprocessing profile; Screen - preprocessing suitable for remote desktop applications; Scan - preprocessing suitable for scanned files; Legacy - uses the engine's default settings for preprocessing images, this is the default option.
-
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 2.
Important: Large-size images may result in an error when the scaling factor is higher than 1.
Output
- Text - The extracted
string. This field supports only
stringvariables. - Result - The extracted
words along with their on-screen position. This field supports only
KeyValuePair <rectangle,string>variables.
Input
- Image - The image that you
want to process. This field supports only
imagevariables.
Common
- DisplayName - The display name of the activity.
Misc
- Private - If selected, the values of variables and arguments are no longer logged at Verbose level.
