When you first start using The Gimp, it may look very different to other graphics programs that you have been using.  This can make it seem hard to do quite simple tasks.  On this page, I will show you how to do the 'easy stuff' - things that you probably found very simple in another program, and that you will soon see are also very simple in 'The Gimp'.


Zooming in and Out

Resizing an Image

 The Difference between Zooming and Resizing

When you zoom in and out on your image, you are not changing the actual size of your image, you are just changing the way you look at it. (Like using a magnifying glass)

When you resize an image, you are changing the number of pixels of information in it, so the actual file size will become smaller if you are making it a smaller size.  When you resize to make it larger, The Gimp has to guess what information to fill in for the missing pixels.  It may not always be what you expect.

If you just need to make your file size smaller but not the actual image size (eg for the web), you can compress your file.

Rotating an Image

To Rotate, right click and choose:  Image>Transforms>Rotate

How to Crop an Image

 

Download and save the image rock.jpg

The first thing that you will notice is that it needs rotating.  Rotate it. Save it.

Next resize it, so that it is only 500 pixels high.  Keep the width in proportion.  Save it as rock1.jpg  Check the file size and make sure that it is less than 60 Kb, so that it is small enough to be emailed.

Now reopen the original image and crop it, so that only the rock is in the picture.  Save it as rock2.jpg
