# TransformedGrayscaleImageUnit

The `TransformedGrayscaleImageUnit` class extends the `IntermediateResultUnit` class and represents a transformed grayscale image unit.

## Definition

*Namespace:* com.dynamsoft.core.intermediate_results

*Assembly:* DynamsoftCaptureVisionBundle.aar

```java
class TransformedGrayscaleImageUnit extends IntermediateResultUnit
```

## Methods

| Methods | Description |
| ------- | ----------- |
| [`getImageData`](#getimagedata) | Gets the `ImageData` object as the image data of the grayscale-transformed image. |
| [`setImageData`](#setimagedata) | Sets the `ImageData` object as the image data of the grayscale-transformed image. |

## Inherited Methods

The following methods are inherited from class [`IntermediateResultUnit`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html).

| Method | Description |
|------- |-------------|
| [`clone`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#clone) | Creates a copy of the intermediate result unit. |
| [`gethashId`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gethashid) | Gets the hash ID of the unit. The hash ID is the unique identifier for the intermediate result unit. |
| [`getOriginalImageHashId`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#getoriginalimagehashid) | Gets the hash ID of the original image. You can use this ID to get the original image via `IntermediateResultManager` class. |
| [`getOriginalImageTag`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#getoriginalimagetag) | Gets the image tag of the original image associated with this unit. |
| [`getType`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gettype) | Gets the type of the intermediate result unit, defined by the enumeration [`EnumIntermediateResultUnitType`]({{ site.dcv_android_api }}core/enum/intermediate-result-unit-type.html?lang=android). |
| [`getTransformMatrix`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#gettransformmatrix) | Gets the transformation matrix via [`EnumTransformMatrixType`]({{ site.dcv_android_api }}core/enum/transform-matrix-type.html). |
| [`replace`]({{ site.dcv_android_api }}core/intermediate-results/intermediate-result-unit.html#replace) | Replaces the old unit with the new unit. |
