Allows to specify downsample options.

To learn more, visit the [Save a Document](https://docs.aspose.com/words/net/save-a-document/) documentation article.

```csharp
public class DownsampleOptions
```

## Constructors

| Name | Description |
| --- | --- |
| [DownsampleOptions](downsampleoptions/)() | The default constructor. |

## Properties

| Name | Description |
| --- | --- |
| [DownsampleImages](../../aspose.words.saving/downsampleoptions/downsampleimages/) { get; set; } | Specifies whether images should be downsampled. |
| [Resolution](../../aspose.words.saving/downsampleoptions/resolution/) { get; set; } | Specifies the resolution in pixels per inch which the images should be downsampled to. |
| [ResolutionThreshold](../../aspose.words.saving/downsampleoptions/resolutionthreshold/) { get; set; } | Specifies the threshold resolution in pixels per inch. If resolution of an image in the document is less than threshold value, the downsampling algorithm will not be applied. A value of 0 means the threshold check is not used and all images that can be reduced in size are downsampled. |

## Examples

Shows how to change the resolution of images in the PDF document.

```csharp
Document doc = new Document(MyDir + "Images.docx");

// Create a "PdfSaveOptions" object that we can pass to the document's "Save" method
// to modify how that method converts the document to .PDF.
PdfSaveOptions options = new PdfSaveOptions();

// By default, Aspose.Words downsample all images in a document that we save to PDF to 220 ppi.
Assert.That(options.DownsampleOptions.DownsampleImages, Is.True);
Assert.That(options.DownsampleOptions.Resolution, Is.EqualTo(220));
Assert.That(options.DownsampleOptions.ResolutionThreshold, Is.EqualTo(0));

doc.Save(ArtifactsDir + "PdfSaveOptions.DownsampleOptions.Default.pdf", options);

// Set the "Resolution" property to "36" to downsample all images to 36 ppi.
options.DownsampleOptions.Resolution = 36;

// Set the "ResolutionThreshold" property to only apply the downsampling to
// images with a resolution that is above 128 ppi.
options.DownsampleOptions.ResolutionThreshold = 128;

// Only the first two images from the document will be downsampled at this stage.
doc.Save(ArtifactsDir + "PdfSaveOptions.DownsampleOptions.LowerResolution.pdf", options);
```
