I'm using PDFViewer to display several documents in my application. Most of them are shown the right way, but there are others that appear "empty", or with some graphic elements but no text. I can see them perfectly with external third party viewers.
I've just downloaded and installed 2019.3.1022, but this issue remains.
I send some samples of PDF that are not showing.
Thank you in advance for your help.
doc.Pages.CropBox = new Rect(150, 150, doc.Pages.Size.Width - 30, doc.Pages.Size.Height - 30);
One should be able to handle the annotations/hyperlinks clicking.
1- the load of a document take a while to load (if successed). 2- An unhandled exception thrown while loading a document (Out of memory or Invalid parameter) the file that i'm trying to load is attached and created using Telerik Document Processing Library. ************** Exception Text ************** System.ArgumentException: Parameter is not valid. at System.Drawing.Bitmap..ctor(Int32 width, Int32 height, PixelFormat format) at System.Drawing.Bitmap..ctor(Image original, Int32 width, Int32 height) at System.Drawing.Bitmap..ctor(Image original) at Telerik.WinControls.PdfViewer.PdfElementsRenderer.RenderImage(ImageSource source, ResourceKey key, BackgroundWorker cancellationToken) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawImage(Image image, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawContentElement(IContentElement contentElement, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawContainer(Container container, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawContentElement(IContentElement contentElement, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawContainer(Container container, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawContentElement(IContentElement contentElement, Graphics graphics) at Telerik.WinControls.PdfViewer.FixedPageRenderer.DrawPage(ContentCollection content, Graphics graphics, Matrix pageTransform) at Telerik.WinControls.UI.FixedPagePreRenderer.rendererWorker_DoWork(Object sender, DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.OnDoWork(DoWorkEventArgs e) at System.ComponentModel.BackgroundWorker.WorkerThreadStart(Object argument) Thank you
PDF Export needs to support certificate signatures so the end user of the document knows the document hasn't been changed.
To reproduce: On a button click call the following method: newPdfViewer.Print(True) When the dialog opens click the Print button, without interacting with another component. You will notice that there will be no effect from your click. Click second time, you can now click. Resolution: This is not with RadPdfView issue since the dialog is Windows dialog For more information please refer to: http://social.msdn.microsoft.com/Forums/windows/en-US/681a50b4-4ae3-407a-a747-87fb3eb427fd/first-mouse-click-after-showdialog-hits-the-parent-form?forum=winforms http://stackoverflow.com/questions/2648977/c-sharp-windows-forms-print-dialog-box-click-ok-twice-to-respond
To reproduce: Open the attached document. You will see that it will be rendered blank due to the NotSupportedException Resolution: This is an unsupported font from our engine. In debug the SL PDF also throw this exception, since the engine does not support this font type. WinForms PDF rendered this documents with delay.
PdfViewer - does not arrange correctly the layout of some pages.
PdfViewer - throws NullReferenceException in GetPages method of PdfContentManager.
There are cases in which some of the images in a pdf file appear with inverted colors. Resolution: The issue is duplicated with feedback item FIX.

FIX. When printing a document using the PrintDocument Control, an 5mm Margin is added to the Top and Left. Resolution: The most of printers set bigger margins in left and top. You can set the Margins of RadPrintDocument to 0.
The RadPdfViewer throws ArgumentNullException when loading pdf file. - "Value cannot be null.Parameter name: page"
