# All Deprecated Features & APIs
> [!NOTE]
> All deprecated APIs are considered unsupported as of the version they are deprecated. They may be removed at any time with no further notice.

<!-- ## Planned

### SHA-1 signatures

To comply with Windows security updates, we will deprecate SHA-1 signatures in a future version. The impact is described below (we take 64bit Windows 7 as an example in below screenshots).

*If the deprecation is implemented:*

* When you try to install the Dynamsoft Service, you will get the following two error for "Unknown Publisher".

![Deprecation-1](/assets/imgs/Deprecation-1.png)

![Deprecation-2](/assets/imgs/Deprecation-2.png)

* When you run the ActiveX Edition in IE, you will get a prompt to allow its execution.

![Deprecation-3](/assets/imgs/Deprecation-3.png)

For more information, check out [Preparing for the deprecation of SHA-1 signatures](https://docs.microsoft.com/en-us/sysinternals/announce/sha1deprecation) from Microsoft.

The prompts are one-time, once you accept the "risk", the software will install and run as usual.

The recommended fix is to patch the operating system, you can find the patch [here](http://www.catalog.update.microsoft.com/search.aspx?q=kb4474419). -->

  + [ `Viewer.singlePageMode` ](/_articles/info/api/WebTwain_Viewer.md#singlepagemode)

* The following APIs in v16.2 are improved based on old APIs in v16.1-.

  + [`Viewer.setViewMode()`](/_articles/info/api/WebTwain_Viewer.md#setviewmode)

    It also accepts the values "-1, -1" which is equivalent to setting `Viewer.singlePageMode` to `true` .

  + [`Viewer.updateUISettings()`](/_articles/info/api/WebTwain_Viewer.md#updateuisettings)

* The following APIs are also deprecated in v16.2

  + `SetViewMode()`

    Use Viewer.setViewMode() instead.

* The following APIs from v16.1- are removed

  + `Viewer.bOnlyShowThumbnailsView`
  + `Viewer.cursorOverThumbnailsView`
  + `Viewer.bindCustomElement()`
  + `Viewer.showCustomElement()`
  + `Viewer.hideCustomElement()`
  + `Viewer.toggleCustomElement()`
  + `Viewer.setSelectedImageArea()`
  + `Viewer.zoomIn()`
  + `Viewer.zoomOut()`

* The following APIs in v16.1- are implemented differently in v16.2  
  + `BindViewer()` with two parameters
  + `UpdateViewer()`

  The two methods above were used to set the size of the viewer or to show the thumbnail viewer. In v16, 2, different APIs are used as shown below:

``` javascript
  /* Set the size of the viewer */
  DWTObject.Viewer.height = 800;
  DWTObject.Viewer.width = 600;
  /* Create a thumbnail viewer, note that this viewer can be hidden or disposed */
  var objThumbnailViewer = DWTObject.Viewer.createThumbnailViewer(thumbnailViewerSettings);
  objThumbnailViewer.show();
  //objThumbnailViewer.hide();
  //objThumbnailViewer.dispose();
  /* updateViewMode() is used to change only the view mode of the thumbnail viewer */
  objThumbnailViewer.updateViewMode(viewMode: ViewMode);
  /* The following two are used to hook or unhook events to the thumbnail viewer */
  objThumbnailViewer.on()
  objThumbnailViewer.off()
```

  + `ShowImageEditor()`

  While this method still works, it's deprecated and the alternative is shown in the code below

``` javascript
  /* The image editor is now created on the fly and can be hidden or disposed */
  var objImageEditor = DWTObject.Viewer.createImageEditor(editorSettings);
  objImageEditor.show();
  objImageEditor.hide();
  objImageEditor.dispose();
```

  + `Viewer.bindCustomElement()`
  + `Viewer.showCustomElement()`
  + `Viewer.hideCustomElement()`
  + `Viewer.toggleCustomElement()`

  As already mentioned, these four methods are removed and the alternative implementation is shown in the code below

``` javascript
  var objCustomElement = DWTObject.Viewer.createCustomElement(document.getElementById("divCustomElement"));
  objCustomElement.show();
  objCustomElement.hide();
  objCustomElement.dispose();
```
