8) Zooming and panning in Gimp 2.10

Sharing buttons:

For this lecture, open: 'Mountains'.

There are two main ways of navigation: zooming and panning.

Let's start with zooming.

Zooming means: zooming in and zooming out.

The fastest way to zoom is by scrolling with the mouse wheel, while holding down the Ctrl key.

If you scroll forward, you zoom in.

If you scroll backward, you zoom out.

The place where you hold your mouse, is where you will zoom in on.

This is very efficient.

Let's say I want to zoom in on this screw.

I hold my mouse above it, press Ctrl, and scroll forward.

If I zoom in very far, I will start to see the building blocks of the image; the pixels.

Another way to zoom is using the Zoom tool.

It is located at the bottom of the toolbar.

With the Zoom tool you can drag an exact area you want to zoom in on.

The fastest way to zoom out again is by pressing: Ctrl-0.

Ctrl-0 will fit the image perfectly on the screen.

Although fitting an image, on the available space on screen is very useful,

it doesn't mean that you see the image at its real size.

To see an image at its real size, its zoom percentage has to be: 100%.

Anything higher than 100% means you're zoomed in,

anything lower than 100% means you're zoomed out.

You can read the zoom percentage at the bottom of the screen.

When you see an image at its real size, so at 100%,

each pixel of the image, will correspond to a pixel of your screen.

The shortcut for real size, or 100%, is: Ctrl-1.

The second way of navigating is panning.

When you're zoomed in on an image, you can move around, or pan,

by pressing down your scroll wheel, and then move your mouse.

When you scroll your mouse wheel forward, you move up.

And when you scroll backwards, you move down.

Pressing the Shift key while scrolling, lets you move left and right.

For moving over longer distances, the scroll bars are very effective.

And finally, at the bottom right of the canvas, there is the 'Navigate display'.

If you click on the little arrow, a thumbnail of the image pops up.

In here you can navigate, by dragging the white border.

The white border represents the canvas you are seeing.

In the next lecture, we will explore the paintbrush.
