The problem I'm trying to solve is that users do not know that the original document may not be what they are seeing in the viewer when there are layers.
A property that indicates
that a document has layers would allow the system to refuse to open the document.
RadPdfViewer can not display annotated PDF file Kindly,i used VintaSoft SDk to Annotate PDF File, File is annotated successfully and i can open it with Adobe Reader and see annotations is added to it but while i try to view annotated PDF file using RadPDFViewer File will displayed without annotations ,only original content displayed. Kindly find my attached AnnotatedPDFfile To be loaded in RadPDfViewer
The attached file lorem-ipsum.pdf is rendered incorrectly in PdfViewer. I suspect it has something to do with kerning, because monospace font is not affected. Adobe Acrobat, Foxit PDF Reader, and Chrome render the file correctly.
The file was created with Pandoc, open source software, converting a markdown file (.md) to .pdf.
When RadPdfViewer is in text selection mode and the user is trying to select a word by double-clicking on it, the last letter of the word is not selected when the word is followed by some symbols like '.', ':', '(', '...'
Also, the CaretPosition is not correct.
The issue is reproducible only on Windows XP. On newer versions of windows, the images are rendered as expected. WORKAROUND: You may try implementing custom filter that handles the CMYK scenario. How to implement custom DCTDecode filter is described in this documentation article: https://docs.telerik.com/devtools/winforms/pdfviewer/customize-and-extensibility/customize-pdf-rendering
Steps to reproduce:
1. Load a PDF document with 0 pages
2. Enter some text in the search textbox and click the next/prev buttons
Expected: the search textbox should be either disabled or should ignore any search operation
Actual: an error occurs
Workaround:
Private Sub pdf_Viewer_DocumentLoaded(sender As Object, e As EventArgs)
If pdf_Viewer.Document.Pages.Count = 0 Then
pdf_Toolbar.SearchTextBox.Enabled = False
pdf_Toolbar.NextButton.Enabled = False
pdf_Toolbar.PreviousButton.Enabled = False
Else
pdf_Toolbar.SearchTextBox.Enabled = True
pdf_Toolbar.NextButton.Enabled = True
pdf_Toolbar.PreviousButton.Enabled = True
End If
End Sub
