SuperPaint - to scale a drawing in the paint layer - create a screen that wipes out half the pixels. First, select Paint on Black from the Paint menu. (This option will cover only the black pixels with the selected pattern, leaving white areas intact.) Select the image to be scaled, click on the middle gray in the gray-scale pattern palette (eighth from the left bottom row), and choose Fill from the Paint menu. Half of the black pixels will turn white. Now, with the image still selected, choose Scale Selection from the Edit menu and click 50% in the dialog box.
