Open the Demo app and load the PDF document with such annotation. The following error occurs:

Enable the customers to work with annotations of type Stamp.

A pop-up annotation displays text in a pop-up window for entry and editing. It typically does not appear alone but is associated with a markup annotation (its parent annotation) and is used for editing the parent’s text.

A specific scanned file is not displayed in the viewer. This lead to empry pages.

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.

On HDPI (200%) Print Preview Dialog bottom buttons are cut off.

Signature fields are not rendered in the PDF while loading it in the RadPdfViewer control.

 

 

Provide a new property that specifies FileName in SaveAs command.

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:

 

Use the attached pdf document and launch the PdfPrintPreviewDialog. As it is demonstrated in the gif file, the preview dialog moves the pages slower than the pdf viewer itself.

Expected behavior: the performance for navigating the pages should be at least identical.

This is the result with R3 2022:

 

 

This is the result with R2 2023 SP1:

 

If the DataError is handled, you can detect what kind of internal errors occur. The document is loaded successfully at the end. If the thumbnails menu is hidden, the load time is much faster.

Load a document with bookmarks and select the bookmarks options. Then, move the splitter:

Expected: the selected option (bookmarks) is unchanged

Actual: the selected option (bookmarks) is not preserved and it is reset

 

Add functionality for a PDF form filler that supports text auto-sizing/shrinking like Adobe:

Introduce locking a document opened in viewer.

Expose API that allows you to access the current editor. Perhaps add some events to the EditingFields class.

The GetSelectedText method returns incorrect spacing with some documents. 

To reproduce: 

The selection position is wrong when each character is drawn with PDF operators.
