How to: Replace a Picture with Another Picture in the Rich Text Editor
The following example demonstrates how to use the PictureFormat.SetPicture method to replace a picture with another picture, and maintain the original format, size, and position.
Document document = richEditControl.Document;
// Set the measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Insert a picture.
Shape picture = document.Shapes.InsertPicture(document.Range.Start, DocumentImageSource.FromFile("Picture_Dog.png"));
// Set the picture size.
picture.Size = new SizeF(3f, 2.5f);
// Align the picture.
picture.HorizontalAlignment = ShapeHorizontalAlignment.Center;
picture.VerticalAlignment = ShapeVerticalAlignment.Top;
// Change the picture's form.
picture.PictureFormat.Preset = ShapeGeometryPreset.RoundedRectangle;
// Display a border around the picture.
picture.Line.Color = Color.Black;
// Replace the picture.
picture.PictureFormat.SetPicture(DocumentImageSource.FromFile("Picture_Cat.png"));
