- ============================================
- How to use the Air Brush* 0.1 desk accessory
- ============================================
-
- The Air Brush DA was adapted from the tool of the same name which is
- included in MacroMind's ComicWorks and GraphicWorks programs. If you haven't
- used the MacroMind Airbrush* before, you'll find that it's an order of
- magnitude more versatile than anything you've seen in MacPaint, FullPaint or
- even the all-around graphics champ, SuperPaint.
-
- GETTING STARTED
- To use the Air Brush DA, first open your Paint application and select
- the bitmap you want to modify and copy it to the Clipboard. Then open the
- Air Brush DA and paste, using the Edit menu. (The Command-key shortcuts for
- Cut/Copy/Paste won't work while Air Brush is active, for some reason.) Your
- image should appear in the Air Brush window.
-
- THE AIR BRUSH WINDOW
- Air Brush opens a window with horizontal and vertical scroll bars; the
- actual size of the document is roughly two screens wide by three screens high,
- or about a thousand by a thousand pixels. Your pasted-in image will appear in
- the upper left corner of this space, but you can use the scroll bars to view -
- and work on - other parts of the Air Brush window.
-
- AIR PRESSURE
- You'll notice that a new menu, "Air," has appeared on your menu bar. When
- you pull it down, you'll see four lines of various thicknesses, the standard
- patterns from your System file, and a box with a number in it (initially 15)
- in the upper left corner of the pattern area. The lines are used to control
- the "air pressure" of your airbrush tool: selecting the dotted line gives the
- lowest pressure and hence the lightest spray; the thickest line gives high
- pressure and hence lays down pigment fastest. To set air pressure, just move
- the cursor over one of the lines until it's framed by a box, then release.
- There's also a keyboard shortcut: the P, [, ] and \ keys correspond to the
- dotted, light, medium and dark line menu choices, respectively.
-
- PATTERN SIZE
- The number shown just below the dotted line on the menu is the diameter
- (in pixels) of your spray pattern. This can be changed in two ways: pressing
- a number key between 1 and 0 (while the menu is not pulled down) will set the
- pattern to one of ten fixed sizes (2, 4, 8, 12, 16, 24, 32, 48, 64, 96), while
- pressing the - or = key will decrease or increase the pattern diameter in
- one-pixel steps.
-
-
- PATTERN
- To select a pattern, just move the cursor over it until it's framed,
- then release. As with the MacPaint airbrush, you can now spray in that
- pattern by holding down the mouse button and moving around the Air Brush
- window; unlike the standard tool, Air Brush sprays in a truly random pattern
- which builds up gradually if you hold the tool stationary. The pattern-size
- box (the one with the number in it) can also be selected; if you do this,
- you get a special effect: a completely random pattern which never builds up
- to more than 50% average density, no matter how long you hold the tool in
- one place. There's also a keyboard shortcut: pressing the Backspace key
- toggles between black and white paint. Finally, holding down the Command key
- while you spray will make your paint transparent.
-
- If you make a mistake, you can undo your last action by pressing the tilde
- (~) key, the one in the upper left corner of the keyboard. Oddly enough, Air
- Brush does not recognize the standard undo shortcut, Command-Z.
-
- SAVING YOUR WORK
- When you're finished using Air Brush, pull down the Edit menu and use the
- copy command to get the document from the Air Brush window into the Clipboard;
- then put away the Air Brush window and paste into your Paint application's
- open document. Only the image (black) portion of the Air Brush document will
- be copied; if that's larger than the document you want to paste into, you
- may have a problem. SuperPaint will offer to scale the selection to fit its
- maximum 8 x 10" drawing area; other applications may not behave so gracefully.
