Exchange has limited options for exporting to an image file, namely from a PDF by using [A3DPDFDocumentExportAsImage](https://docs.techsoft3d.com/hoops/exchange/api/c/functions/A3DPDFDocumentExportAsImage.html#a3dpdfdocumentexportasimage).

For a Revit file, I think your best bet is to actually use Visualize Desktop/Mobile API. Please see the `Image` class:

> **[HPS.Image - Image — HOOPS Visualize Desktop Documentation](https://docs.techsoft3d.com/hoops/visualize-desktop/api_ref/cs/class_h_p_s_1_1_image.html#image)**
>
> Public Types

A quick example would be:

```auto
HPS::Image::File::Export("output.png", myWindowKey, 150, 150, HPS::Image::Format::Png, false);

```
