dynamically resize images in a CR ver. 10

I am trying to dynamically resize images in a CR ver. 10.

I have placed the height/width in a field with the image. How can I format the image to change their height/width?

I have adjusted the logo using:

Code:

---

objReport.ReportDefinition.Sections("Section3").ReportObjects("LogoImage1").Height = TwipsY
objReport.ReportDefinition.Sections("Section3").ReportObjects("LogoImage1").Width = TwipsX

---

But the images are all different aspect ratios.

Can anyone help or can it not be done?

I assume people printing a catalogue would have the same problem.
