## ImageSize class

Contains information about image size and resolution.
To learn more, visit the [Working with Images](https://docs.aspose.com/words/nodejs-net/working-with-images/) documentation article.




### Constructors
| Name | Description |
| --- | --- |
| [ImageSize(widthPixels, heightPixels)](./constructor/#number_number) | Initializes width and height to the given values in pixels. Initializes resolution to 96 dpi. |
| [ImageSize(widthPixels, heightPixels, horizontalResolution, verticalResolution)](./constructor/#number_number_number_number) | Initializes width, height and resolution to the given values. |

### Properties

| Name | Description |
| --- | --- |
| [heightPixels](./heightPixels/) | Gets the height of the image in pixels. |
| [heightPoints](./heightPoints/) | Gets the height of the image in points. 1 point is 1/72 inch. |
| [horizontalResolution](./horizontalResolution/) | Gets the horizontal resolution in DPI. |
| [verticalResolution](./verticalResolution/) | Gets the vertical resolution in DPI. |
| [widthPixels](./widthPixels/) | Gets the width of the image in pixels. |
| [widthPoints](./widthPoints/) | Gets the width of the image in points. 1 point is 1/72 inch. |

### Examples

Shows how to resize a shape with an image.

```js
// When we insert an image using the "InsertImage" method, the builder scales the shape that displays the image so that,
// when we view the document using 100% zoom in Microsoft Word, the shape displays the image in its actual size.
let doc = new aw.Document();
let builder = new aw.DocumentBuilder(doc);
let shape = builder.insertImage(base.imageDir + "Logo.jpg");

// A 400x400 image will create an ImageData object with an image size of 300x300pt.
let imageSize = shape.imageData.imageSize;

expect(imageSize.widthPoints).toEqual(300.0);
expect(imageSize.heightPoints).toEqual(300.0);

// If a shape's dimensions match the image data's dimensions,
// then the shape is displaying the image in its original size.
expect(shape.width).toEqual(300.0);
expect(shape.height).toEqual(300.0);

// Reduce the overall size of the shape by 50%. 
shape.width *= 0.5;

// Scaling factors apply to both the width and the height at the same time to preserve the shape's proportions. 
expect(shape.width).toEqual(150.0);
expect(shape.height).toEqual(150.0);

// When we resize the shape, the size of the image data remains the same.
expect(imageSize.widthPoints).toEqual(300.0);
expect(imageSize.heightPoints).toEqual(300.0);

// We can reference the image data dimensions to apply a scaling based on the size of the image.
shape.width = imageSize.widthPoints * 1.1;

expect(shape.width).toEqual(330.0);
expect(shape.height).toEqual(330.0);

doc.save(base.artifactsDir + "Image.ScaleImage.docx");
```
