### getRectangle() {#getRectangle--}
```
public RectangleF getRectangle()
```


Gets a rectangular region that defines the starting and ending points of the gradient.

**Returns:**
[RectangleF](../../com.aspose.imaging/rectanglef) - A `com.aspose.imaging.RectangleF` structure that specifies the starting and ending points of the gradient.
### setRectangle(RectangleF value) {#setRectangle-com.aspose.imaging.RectangleF-}
```
public void setRectangle(RectangleF value)
```


Sets a rectangular region that defines the starting and ending points of the gradient.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | [RectangleF](../../com.aspose.imaging/rectanglef) | A `com.aspose.imaging.RectangleF` structure that specifies the starting and ending points of the gradient. |

### getAngle() {#getAngle--}
```
public float getAngle()
```


Gets the gradient angle.

**Returns:**
float - The gradient angle.
### setAngle(float value) {#setAngle-float-}
```
public void setAngle(float value)
```


Sets the gradient angle.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | float | The gradient angle. |

### isAngleScalable() {#isAngleScalable--}
```
public boolean isAngleScalable()
```


Gets a value indicating whether `LinearGradientBrushBase.Angle` is changed during transformations with this `LinearGradientBrushBase`.

```
public boolean getGammaCorrection()
```


Gets a value indicating whether gamma correction is enabled for this `LinearGradientBrushBase`.

**Returns:**
boolean - The value is true if gamma correction is enabled for this `LinearGradientBrushBase`; otherwise, false.
### setGammaCorrection(boolean value) {#setGammaCorrection-boolean-}
```
public void setGammaCorrection(boolean value)
```


Sets a value indicating whether gamma correction is enabled for this `LinearGradientBrushBase`.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| value | boolean | The value is true if gamma correction is enabled for this `LinearGradientBrushBase`; otherwise, false. |
