Modify annotation on FreeTextAnnotationChanged event
Hello,
I'm trying to modify the width and height of a free text annotation when it is created. I have an eventhandler on the FreeTextAnnotationChanged event of the PdfViewerControl (simplified version):
private void PdfViewerControl_FreeTextAnnotationChanged(object sender, FreeTextAnnotationChangedEventArgs e)
{
if (e.Action == AnnotationChangedAction.Add)
{
e.Settings.Width = _labelWidth;
e.Settings.Height = _labelHeight;
}
}
The width and height are being stored in a private variable (_labelWidth and _labelHeight). When the user resizes the textbox (e.Action == AnnotationChangedAction.Resize), the new width and height are stored in these private variables. I already figured out that I have to swap them when the orientation is landscape:
if (e.Action == AnnotationChangedAction.Resize)
{
if (PdfViewerControl.LoadedDocument.Pages[e.PageNumber - 1].Rotation == Syncfusion.Pdf.PdfPageRotateAngle.RotateAngle90 ||
PdfViewerControl.LoadedDocument.Pages[e.PageNumber - 1].Rotation == Syncfusion.Pdf.PdfPageRotateAngle.RotateAngle270)
{
_labelWidth = e.NewBounds.Height;
_labelHeight = e.NewBounds.Width;
}
else
{
_labelWidth = e.NewBounds.Width;
_labelHeight = e.NewBounds.Height;
}
}
This works like expected on a standard A4 sized portrait page. But when I open a A3 sized landscape PDF and create a new free text annotation with the modified width and height, the selection box does not match the actual textbox:
Can someone help me solve this issue or is it possible to share the code that is being executed when a new FreeTextAnnotation is created by selecting the tool on the toolbar and clicking somewhere in the document?
Thanks!
Edit: I'm explicitly not looking for a solution that requires the document to be saved and reloaded. We work with large PDF files and it takes about 5 seconds to load. It's not a workable solution to have to wait 5 seconds after each click.
