how to combine viewer, annotation in same viewer.
image.png (20.4 KB)
When rendering to PNG is enabled the search feature is not supported. I have enabled search and rendering to HTML in the application you have shared - web-forms-vb-app-with-search.zip. All the changes were made in the ViewerApiController.vb file. After you run the app you can see the search icon - search.png (61.0 KB).
Regarding your second question, you have already created a separate post - How to combine viewer, annotation in same viewer. Let’s continue the discussion there.
To enable thumbnails you can set Key .thumbnails = True.
To enable print you have to set Key .print = True and add one more action
<HttpPost>
<Route("PrintPdf")>
Public Function PrintPdf(ByVal request As DocumentDescriptionRequest) As IHttpActionResult
Dim filePath = Path.Combine(_storagePath, request.Guid)
Dim loadOptions = New LoadOptions With {
.Password = request.Password
}
Using viewer As Viewer = New Viewer(filePath, loadOptions)
Dim bytes = GetPdf(viewer)
Dim fileName = Path.GetFileNameWithoutExtension(request.Guid)
Dim response = HttpContext.Current.Response
response.ContentType = "application/pdf"
response.AddHeader("Content-Disposition", String.Format("attachment; filename={0}", fileName))
response.BinaryWrite(bytes)
response.End()
End Using
End Function
Private Function GetPdf(ByVal viewer As Viewer) As Byte()
Dim memoryStream As MemoryStream = New MemoryStream()
Dim viewOptions As PdfViewOptions = New PdfViewOptions(Function() memoryStream, Function(stream)
End Function)
viewer.View(viewOptions)
Dim bytes As Byte() = memoryStream.ToArray()
Return bytes
End Function
Here is the updated version of ViewerApiController.zip (1.9 KB).
thanks for reply download not work
thumbnail has like this
image.png (24.7 KB)

To enable download you have to set Key .download = True and add one more action
<HttpGet>
<Route("DownloadDocument")>
Public Function DownloadDocument(ByVal path As String) As IHttpActionResult
Dim filePath = IO.Path.Combine(_storagePath, path)
Dim bytes = File.ReadAllBytes(filePath)
Dim fileName = IO.Path.GetFileName(path)
Dim response = HttpContext.Current.Response
response.ContentType = "application/octet-stream"
response.AddHeader("Content-Disposition", String.Format("attachment; filename={0}", fileName))
response.BinaryWrite(bytes)
response.End()
End Function
We’ll take a look at the issue with thumbnails and update you.
To make thumbnails.png (80.1 KB) work properly try updating ViewerApiController.zip (2.1 KB) or check the complete app - web-forms-vb-app-with-thumbnails.zip.
