I uploaded an image to a button via the file dialog. I want to change the resolution of the image through a numeric upDown control. So that when the value changes, the image is 'redrawn' and it has the new resolution. How can I achieve this?...thanks in advance.

Hello aarif, what isn't clear about the question?

Additional :
depending on your exact goal : You could also customize your control by overriding the OnPaint-method to be able to change it's behaviour like you want to have it.
But for this it's also necessary to know more about the "why" and perhaps also the "how to" ...

I have the same opinion ... you should write something more about the "why".
If you want to have a new resolution you have to re-calculate the image. Another possibility could be to use a PictureBox which is resized by you ...

PictureBox will not change the resolution of the image. But I agree, "why" is more important. What is the purpose of the change?

Ralf Meier 22-Sep-15 5:57am

You are right, PictureBox don't changes the resolution ... but it could change the displayed size. Perhaps that is what the inquirer wants to do ...
