You can import a standard image file to use as the basis of a new painting by opening the File menu and choosing ‘Import Image File’.
Images can also be imported to existing paintings as a new layer by choosing ‘Import Image to layer’ in the File menu. After importing the image, you can scale, rotate and resize it, then either click the check button in the Transform window or press enter to confirm.
To export your painting as a standard image file, open the File menu and choose ‘Export Image File’. You can select the type of image you want to export here.
