I was trying to make the display size bigger for a zoom-in image. I followed the instructions on this page, and the zoom-in effect worked: the original full image shown on the left panel and the zoom-in effect shown on the right.
However, the entire display box for both the full-image panel and the zoom-in panel is small. Anyway to revise the codes to make the overall display window bigger? Tried different ways to revise the codes but couldn’t make it to work.
