# OCRScrapeBase Class

> * Namespace: `UiPath.OCR.Contracts.Scrape`
* Assembly: `UiPath.OCR.Contracts`

## Definition

* Namespace: `UiPath.OCR.Contracts.Scrape`
* Assembly: `UiPath.OCR.Contracts`

## Description

An abstract class that defines the behavior of an `IOCRActivity` in a screen scraping operation.

## Members

#### Constructors

* `OCRScrapeBase(UiPath.OCR.Contracts.Activities.IOCRActivity)` - Initializes a new instance of the OCR scrape engine. The constructor argument is an Activity that implements the `IOCRActivity`.

#### Methods

* `CreateOcrEngineActivity(System.Activities.InArgument<System.Drawing.Image>)` - Returns a new OCR Activity object with the specified Image set as an InArgument.
* `GetScrapeArguments()` `System.Collections.Generic.Dictionary<string, object>` - Collects all the `UiPath.OCR.Contracts.Activities.IOCRActivity` arguments from the scrape control. These arguments is used to run the `UiPath.OCR.Contracts.Activities.IOCRActivity`, `PerformOCR` method and to fill the activity arguments when the activity is created to be used in a workflow.
* `GetScrapeControl()` - Gets the control that is shown on the screen.
* `GetScrapeControl(UiPath.OCR.Contracts.Scrape.ScrapeEngineUsages)` - Returns the UserControl that can be used to configure this OCR engine.
* `OCRScrapeBase(UiPath.OCR.Contracts.Activities.IOCRActivity)` - Activity constructor.
* `ScrapeOCRAsync(System.Drawing.Bitmap)` - Asynchronously performs OCR on the specified Image.
* `ScrapeOCRAsync(System.Drawing.Bitmap, UiPath.OCR.Contracts.Scrape.ScrapeEngineUsages, System.Threading.CancellationToken)` - Asynchronously performs OCR on the specified Image. Can be canceled. Allows the caller to specify whether the OCR should be performed in Screen or Document mode.

#### Properties

* `Name` - Custom display the name given to this OCR. This name is visible in certain drop-down controls.
* `Priority` - Custom priority is given to this OCR. Lower values indicate higher priority. This determines the ordering of OCR engines in certain drop-down controls.

## Code Sample

```
internal class SampleOCRScrape : OCRScrapeBase
    {
        private readonly ScrapeEngineUsages _usage;
        private readonly SampleScrapeControl _sampleScrapeControl = new SampleScrapeControl();

        public override ScrapeEngineUsages Usage { get; } = ScrapeEngineUsages.Document | ScrapeEngineUsages.Screen;

        public SampleOCRScrape(IOCRActivity ocrEngineActivity, ScrapeEngineUsages usage) : base(ocrEngineActivity)
        {
            _usage = usage;
        }

        public override ScrapeControlBase GetScrapeControl()
        {
            return _sampleScrapeControl;
        }

        public override Dictionary<string, object> GetScrapeArguments()
        {
            return new Dictionary<string, object>
            {
                { nameof(SampleOCRAsyncCodeActivity.CustomInput), _sampleScrapeControl.SampleInput }
            };
        }
    }
