`UiPath.Core.Activities.GoogleCloudOCR`

Extracts a string and its information from an indicated UI element or image using the
Google Cloud OCR engine. It can be used with other OCR activities, such as [Click OCR Text](https://docs.uipath.com/activities/other/latest/ui-automation/click-ocr-text), [Double Click OCR
Text](https://docs.uipath.com/activities/other/latest/ui-automation/click-ocr-text), [Hover OCR Text](https://docs.uipath.com/activities/other/latest/ui-automation/hover-ocr-text), [Get OCR Text](https://docs.uipath.com/activities/other/latest/ui-automation/get-ocr-text), and [Find OCR Text Position](https://docs.uipath.com/activities/other/latest/ui-automation/find-ocr-text).

## Properties

### **Common**

* **DisplayName** - The display
  name of the activity.

### **Input**

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

### **Logon**

* **ApiKey** - The API key used
  to provide you access to the Google Cloud OCR.

### **Misc**

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

### **Options**

* **DetectionMode** -
  Indicates what detection flag to send to the Google Cloud Vision OCR. Select
  one of two options: **TextDetection**, **DocumentTextDetection**. The
  default value is **TextDetection**.

  :::important
  The **TextDetection** mode
  does not report Confidence values for the identified words. When the OCR
  engine is used within the [Digitize Document](https://docs.uipath.com/activities/other/latest/user-guide/digitize-document) activity, all
  OCR Confidence values, for all words, will be set to -1 (Unknown).
  :::
* **ExtractWords** - If this
  check box is selected, the on-screen position of each detected word is
  extracted.
* **Language** - The language
  used by the OCR engine to extract the text from the UI element or image. For the
  Google OCR engine, this field needs to contain the language file prefix, such as
  “rom” for Romanian, “ita” for Italian, and “fra” for French. You can find the
  supported language prefixes on [this page](https://cloud.google.com/vision/docs/languages#supported-langs).
* **ResizeToMaxLimitIfNecessary** - When selected, the engine attempts
  downsizing the target image so that it does not exceed the size limit of the
  Google Cloud Vision engine. By default, this check box is cleared.
* **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 text.
  This field supports only `string` variables.
* **Result** - The extracted
  words along with their on-screen position. This field supports only
  `KeyValuePair<rectangle,string>` variables.
