Selected fragment of the graphic image can be copied to clipboard – the command Edit+Copy.
The command Edit+Cut places selected fragment to clipboard and cleans the fragment, that is, fills it with transparent color. Thus, this command can be considered as two commands: Edit+Copy and Edit+Clean Selection.
At the command Edit+Paste the contents of the clipboard will be placed to the top left corner of the image as selected fragment which can be moved to any place of the pane.
The command Edit+Paste with Transparency differs from the previous command in the fact that if the fragment being inserted has pixels having the color corresponding to the current filling color, when it is inserted the color of these pixels is changed to transparent one.
