I am using RadPDFViewer, i built a specific toolbar for manage the funcionalities of the viewer.
I didn´t found the any event when the current page is changed in viewer. I would like to show a label "Page NN of TT".
I found this "https://www.telerik.com/forums/page-changed-detected", but didn´t have this event in RadPDFViewer.
Whats the better solution for the raise event when the current page displayed is changed?
Can you help me ?!?
The current implementation relies on valid cross-reference table offsets in the PDF documents so that PDF objects are easily found and parsed. However, a mechanism for importing documents with invalid cross-reference table offsets may be implemented.
The attached project shows how to repair such documents.
When a PDF document contains images compressed with CCITTFaxDecode with applied BlackIs1 parameter, black color is visualized as white and white as black.
Please refer to the attached sample screenshot demonstrating how the document look in Adobe and in RadPdfViewer.
Currently, RadPdfViewer uses WPF DrawingContext class for drawing page elements to a Canvas. When PDF page has many content elements (usually geometries) drawing the page may be time-consuming and freezes the UI. Instead, we should consider implementing another approach for rendering the content asynchronously which would improve the user experience.
Some files when opened with PdfViewer will throw a KeyNotFoundException which will be handled. Parts of the text in the file might or might not be missing.
