### PDFViewCtrl

* The `PDFViewCtrl` AnnotationCanvas (available through `PDFViewCtrl.GetAnnotationCanvas`) is now positioned differently relative to the PDFViewCtrl’s content.

* Open and view non-PDF documents including docx, jpeg, jpg, gif, png and cbz while it is being converted to PDF via `PDFViewCtrl.OpenUniversalDocument` using a `DocumentConversion` from `Convert.UniversalConversion`
* The class `PDFViewCtrlThumbnailRequestHandler`, available via the property `PDFViewCtrl.ThumbnailResponseHandler`, which can receive thumbnails from `GetThumbAsync` in a background thread
* The `PDFViewCtrl` can now animate zooming, see `SetZoom`, `SmartZoom`, and `SetPageViewMode` to animate a zoom change
* Use `PDFViewCtrl.SelectWithSnapping` and `PDFViewCtrl.SelectWithSmartSnapping` to alter whether or not text selection should select whole words
* Set any DuoTone color mode using `PDFViewCtrl.SetColorPostProcessColor`

### Tools

* Tools controls have updated appearance to match UWP default styles

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.apryse.com/uwp/changelogs/version-6/v6-7-1.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
