For a blogger like me, picture is an important part. We need to create picture, take screenshot for tutorial and other tasks. Sometimes we need to resize or rescale pictures so it will fit on a blog so it load faster. In Windows, there are bunch application that can be used to take screenshot and resize the picture automatically. In Linux, especially Mandriva 2011, I usually use Gwenview to resize my pictures. When I take screenshot using Ksnapshot in full screen mode, the file size is very big sometimes.
How to resize picture using Gwenview:
Step 1. Open Gwenview
Step 2. Open your picture using File | Open menu
Step 3. Go to Edit | Resize. You will see a new resize window opened.
Enter the new size of the picture and press Resize. Now you can save or save as the resized picture. Additionally, you can mirror, rotate your picture easily using Gwenview.
