Opening, viewing and zooming an image

Most image-processing programs enable at least the following tasks:

  • storing images in different file formats
  • rotating, cropping and mirroring images
  • fixing e.g. brightness, scratches and other problem

Opening and zooming in on an image

When you want to modify an image that is important to you, you should store the image under another name as a separate file to ensure that you do not store the modifications in the original by mistake.

Open a new image for processing by opening the File menu and selecting Open in the image-processing program. This will open up a window for selecting a file to be opened. Select the disc unit and directory where the image is stored. Please note that the program will only show files of the same type as the type selected under Files of type. if the image you want is not shown, open the drop-down menu and select the correct file type. If you select All files, you will see all the images in a file format that the program recognizes. When you have found the image you want, select it with the mouse and click on Open.

The image will open on the desktop of the program and fitted to the size of the screen. In the example, the image is shown in size 1:4 i.e. 25 %. you can use the zoom button to zoom in and out of the image: click on the button once and then click on the image with your left mouse button to zoom in and with the right button to zoom out of the image.

Please note that the zoom tool does not change the image in any way: the image itself is not enlarged or minimized.
