To move the penguin to a warmer place, we select "Change Background" in the post-matting-menu. After matting, a file-browser will open and you will be able to search for the background-image that will serve as the background for the penguin: Navigate to your preferred background-image, select it and then click "Open".
Now, a dialogue opens and you will be able to choose the size of the background-image individually. You can choose between "Auto", "As original canvas size" and "As new base layer size". To select a different background-image, click on the button in the dialogue-box. To confirm your setting click "OK", to cancel the process click "Cancel".
Afterwards, the object will be displayed in front of the new background:
If you click on the image now, hold down the mouse button and move the mouse back and forth. Like this, you will be able to move the object, in this case the penguin, as you like. If you move the object a little, so that the edges of the image are displayed, you can also enlarge or reduce the size of the object by moving the cursor to the corner of the image until the arrow shown appears:
Hold down the left mouse button and move the mouse to change the size. When you move the cursor to an area outside this border, the following icon appears:
Then, hold down the left mouse button and move the mouse to rotate the object at any angle. Theoretically, you could turn the penguin upside down. If you are satisfied with the size, angle and position of the object, click on the “OK”-button in the middle of the image:
The adjusted image now appears in the user interface.
In this case, the penguin was reduced in size and moved to the left. In addition, the cropping result, i.e. the penguin with a transparent background, is present in the area of the layers (red arrow in the image). Like this, you can proceed with the cropped object afterwards (edit, save etc.) if you don’t like the selected background after all.
To display the penguin without a background image, simply deactivate the background layer by clicking on the “eye"-symbol.
