Hello Nicklas,
After loading the document, you can enumerate the ImageInline elements and scale them according to the actual page size:
private void ScaleImages()
{
IEnumerable<ImageInline> images = this.radRichTextEditor1.Document.EnumerateChildrenOfType<ImageInline>();
foreach (ImageInline image in images)
{
Telerik.WinControls.RichTextEditor.UI.Size size = this.GetScaledSize(image.Width, image.Height);
image.Size = size;
}
}
private Telerik.WinControls.RichTextEditor.UI.Size GetScaledSize(double originalPixelWidth, double originalPixelHeight)
{
Telerik.WinForms.Documents.Layout.Padding sectionmargin = this.radRichTextEditor1.Document.CaretPosition.GetCurrentSectionBox().AssociatedSection.ActualPageMargin;
if (originalPixelWidth == 0 || originalPixelHeight == 0)
{
originalPixelWidth = 10;
originalPixelHeight = 10;
}
double width = originalPixelWidth;
double height = originalPixelHeight;
Section currentSection = this.radRichTextEditor1.Document.CaretPosition.GetCurrentSectionBox().AssociatedSection;
Telerik.WinForms.Documents.Model.SizeF pageSize = (Telerik.WinForms.Documents.Model.SizeF)currentSection.GetType()
.GetProperty("ActualPageSize", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(currentSection);
double maxWidth = pageSize.Width - (sectionmargin.Left + sectionmargin.Right);
double maxHeight = pageSize.Height - (sectionmargin.Top + sectionmargin.Bottom);
width = Math.Min(maxWidth, width);
height = Math.Min(maxHeight, height);
double ratio = originalPixelWidth / originalPixelHeight;
width = Math.Min(width, height * ratio);
height = width / ratio;
return new Telerik.WinControls.RichTextEditor.UI.Size(width, height);
}
I hope this will help.
Regards,
Hristo
