Rescale Images programmatically prior to inserting into document

Hi Jason,
Thank you for contacting us. I am afraid that the XtraRichEdit does not have an event that fires when an image is inserted in a document. However, to accomplish your task, you can handle the RichEditControl.ContentChanged event with the following code:

C#
private int count = 0;  
private void Form1_Load(object sender, EventArgs e) {  
    DocumentImageCollection collection = richEditControl1.Document.GetImages(richEditControl1.Document.Range);  
    count = collection.Count;  
}  

private void richEditControl1_ContentChanged(object sender, EventArgs e) {  
    DocumentImageCollection collection = richEditControl1.Document.GetImages(richEditControl1.Document.Range);  
    if (collection.Count < count) {  
        count -= 1;  
    }  
    if (count != collection.Count && collection.Count != 0) {  
        DocumentImage documentImage = collection[collection.Count - 1];  
        SizeF size = documentImage.Size;  
        count = collection.Count;  
    }  
}  

Visual Basic
Private count As Integer = 0  

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs)  
    Dim collection As DocumentImageCollection = richEditControl1.Document.GetImages(richEditControl1.Document.Range)  
    count = collection.Count  
End Sub  

Private Sub richEditControl1_ContentChanged(ByVal sender As Object, ByVal e As EventArgs)  
    Dim collection As DocumentImageCollection = richEditControl1.Document.GetImages(richEditControl1.Document.Range)  
    If collection.Count < count Then  
        count -= 1  
    End If  
    If count <> collection.Count AndAlso collection.Count <> 0 Then  
        Dim documentImage As DocumentImage = collection(collection.Count - 1)  
        Dim size As SizeF = documentImage.Size  
        count = collection.Count  
    End If  
End Sub  

Please try this solution and let us know the results.
Thanks,
Sergi
