I was asked how to crop an image with IrfanView, so I created this basic tutorial, and decided I might as well post it on my weblog.
Please feel free to let me know what you think of it.
Before we begin, open IrfanView.
NOTE: For all actions here, use the primary mouse button - almost always the one on the left hand side.
The first step is to load the image file.
Simply click the 'Open' button, and browse to the file in the usual way.
With the image open, move the mouse cursor to the top left corner where you want the image cropped:
Press down the mouse button and hold it down. The cursor will change to a crosshair.
Drag the mouse down and to the right whilst holding the button and you will create a rectangle on screen.
Make it the appropriate size for your crop. (If in doubt, make the area slightly larger.)
Release the mouse button and the rectange will stay where it is:
Go to the Edit menu and select the Crop selection option. Alternatively, press Ctrl-Y on the keyboard.
Your image has now been cropped to the selected area.
You now need to save the crop which you have made. Goto the File menu and select Save As.
(Alternatively, press S on the keyboard.)
Enter in a new filename for the image. If you need the image to be high quality, save as TGA.
Otherwise, a high quality JPG is a good choice. For JPG, ensure the "Show options dialog" box is ticked.
If you save as JPG, ensure you set the quality to the maximum (100% quality 0% compression)
That's it - press the save button and you're done.
You can now repeat these steps for other images.
