The only parts that may need further explanation are the ones related to padding. „Padding” is the color shown around the edges of the image. You can choose among four colors for the padding color: to use the color specified by the current theme; to use the light or dark colors specified for checks, such as represent transparent parts of the image; or to use a custom color, which can be set using the color button for „Custom padding color”.

Keep canvas padding in Show All mode: in this mode (Secțiune 5.3, „Show All”), you can see pixels outside the canvas. When this option is not checked, the area outside the canvas is filled with a checkerboard pattern, even if you have selected a custom padding color. When the option is checked, the canvas has the custom padding color.
