Zoom Image with GDTwain

Post by werner » Thu Sep 27, 2007 12:29 am

Is possible make a zoom of a scan image with this component, if the answer is positive you have a example of how to do that?

thanks.

Hi,

You can use the Resize method:

Ex:

Code: Select all

call twain1.Resize(3000, 3000)

I don't understand what you mean by "how to know what image is to be resized".

Can you specify me what you want to do exactly ?

Regards,

Loïc
