    Question

    Hi,

    I've got an image in a picture box and I need the user to see close up, like 25 pixels squared, around where the cursor is pointing to. Any idea on how to do it? I've tried using the MouseMove event, and getpixel then using bitblt to create the zoomed in image. But it slows down the applictaion greatly. Any ideas??

    Oh.. and also how do you convert Inches into pixels?

    Thanks a lot

    For your first problem, you can use StretchBlt. For your 2nd problem, I believe an inch is 96 pixels.
