Actually, when we go to image editor from the RadRichTextBox, we've got the original image's size but not the width and height in the document. When we need to format pictures of a document with equal size, we are using the document's size, not the picture's size. Thanks
Hi Partick, You could replace the default ImageEditorDialog and customize it to show the desired values. The width and height of the image inside the document are preserved in the corresponding properties of the image object, passed as a parameter to the ShowDialog() method. There is an example in our XAML SDK repository, which you could use as a reference for the implementation: https://github.com/telerik/xaml-sdk/tree/master/RichTextBox/CustomImageEditorDialog Regards, Tanya
