I need a 10% smaller duplicate of my previous scanned picture, but it's got to have the same size. I need a border arround my picture, that's why I have to shrink it.    Report

01-17-2007, 2:03 Maen Hasan Joined on 08-05-2004 Posts 1,795 Re: Resizing an image Hello, You can use the Size method (Main Control) to resize the bitmap to a new width and height. For more information, please refer to the LEADTOOLS documentation and read the related topic. Thanks, Maen Badwan LEADTOOLS Technical Support    Report

Use a second control and create a blank image with the same size and pixel depth as the original using CreateBitmap method. 2. Fill the new image with the border color you want using the Fill method 3. Resize (shrink) the original image using the Size method 4. Copy the pixel data from the 'shrunk' image to the new image using the Combine method. Thanks, Maen Badwan LEADTOOLS Technical Support    Report
