ProArtisan 2 Demo Disc Tutorial
===============================

This program requires a minimum of 2Mb of memory.

ProArtisan 2 uses outline fonts if available. Fonts are supplied with the
release version of the program but not this demo version so if you want to
use fonts you must provide your own. System font cannot be used for text.

ProArtisan 2 is a multi-mode art and image processing application for the
range of Acorn Risc OS machines. A great deal of effort has gone into
creating a user interface that gives access to the power of ProArtisan 2
without making it complex to use.

Using ProArtisan 2 you can create and manipulate stunning images with ease.
The user interface has been designed to be as intuitive as possible so that
even inexperienced users can access its features without constant reference
to the manual.

You can copy the demo version of ProArtisan 2 and give copies to friends. It
can also be loaded onto a hard disc and run from there.

IMPORTANT: ProArtisan 2 makes extensive use of the Acorn !Help application
supplied with your computer. This will explain the features and functions
available to you. Please use it.

NOTE: The help information detailed above is set up for Risc OS 3.10 and
later. This provides help on menus which is not available under Risc OS 2.
Risc OS 3 also allows us to use abbreviations which are then expanded out
to provide the full message. Risc OS 2 does not provide this facility so you
should substitute the following abbreviations as explained below:

\D Drag SELECT to

\R Move the pointer right to

Technical information
=====================

ProArtisan 2 is a 256-colour painting package. These colours are held as 24
bit values and can be selected from a palette of 16.7 million colours - even
on Risc OS 2. However, unless you have additional hardware such as the
Computer Concepts/Wild Vision Colour Card or one of the State Machine cards
you will be unable to see these additional colours on your computer and we
suggest that you do not attempt to alter colours.

When one of these cards is fitted you will be able to choose and see any of
the 16.7 million colours.

Images created in ProArtisan 2 can be any size or resolution provided that
your machine has enough memory and it supports the resolution that you want
to work in. Internally your images are always held at high resolution and in
24 bit colour, even when you work in a low resolution or low colour mode.
When you return to a higher resolution mode the image is restored to the
correct resolution. In other words, changing mode does NOT convert the image
to that mode and potentially lose information. The image is only converted
to another mode at save time and only then if you instruct ProArtisan 2 to
save in another mode.

===========================================================================

A Short Tutorial
================

To get you into ProArtisan 2 as quickly as possible the following tutorial
takes you through manipulating an image to introduce some of the basic
tools. Remember that you can use tools in conjunction with others and it is
this which makes ProArtisan 2 so powerful. Do not be afraid to try out
different things as there are so many possible combinations that we are
unable to cover them all in this tutorial. We will try to point out
interesting effects when appropriate.

The image that we are going to create uses several concepts which are
central to the ProArtisan 2 philosophy.

Instructions to use a particular menu item are written as

Paint -> Fill -> Plain

where Paint is the name of the icon in the Tool pane, Fill is the item in
the main Paint menu and Plain is the item in the Fill sub menu.

The target image with an overlaid grid is shown in the magazine.

Before going on we need to explain to you what a Frisket is. ProArtisan 2
has a Frisket facility which enables you to protect parts of the canvas from
alteration by any of the tools. It has the reverse effect of a cardboard
stencil. With a stencil you can only paint through the stencil onto the area
where the stencil is cut out. With a Frisket the area 'cut out' cannot be
painted on.

The word frisket originally referred to a frame on a hand printing press
that carried a piece of parchment to protect the non printing areas. So any
area defined as a frisket in ProArtisan 2 is a non printable area, so you
cannot change it.

If you are creating a frisket the palette changes to show just two colours -
Set Frisket and Unset Frisket. The colours shown are normally red and a
cross hatch. The red colour can be changed in the Process menu with the
Frisket Colour option.

If possible use a multiscan monitor in mode 28. If you do not have a
multiscan monitor use mode 15 instead.

Diagram 1 in the magazine introduces the Tool pane for your reference.

1) Load ProArtisan 2 by double clicking on the !ProArt icon in the
directory display and click on the icon on the icon bar to bring up the
Create window. Create a canvas 400 pixels wide by 400 pixels high.

2) Click on the Draw icon and press Menu with the pointer on the canvas.
Click on the Grid item to turn the grid on. Set the grid size to 48 units
in the Grid sub menu. This makes your canvas approximately 15 by 15 grid
squares.

3) Click on the Sprite icon, which also brings up the Sprite pool window.
Drop the sprite called Cheetah onto the Sprite pool window to load it into
the pool.

4) Click on the Vertical Sprite Flip icon to flip the cheetah vertically.

5) Click on Sprite -> Sphere and drag out a sphere with a radius of 2 grid
units in the lower half of the screen. Drag out the sphere horizontally to
lock to the horizontal grid lines. Dragging diagonally locks to the diagonal
grid points.

6) Use Process -> Filters -> Darken set to 40% to darken the image.

7) Click on Sprite -> Vertical Sprite Flip icon to flip the cheetah
vertically.

8) Add another sprite sphere the same size but overlapping by one unit as
shown in Diagram 2 in the magazine.

9) Select white from the Palette and set the Opacity slider to 20%. Goto
Paint -> Brush Shape and select a medium brush size. Using Paint -> Paint
lighten the area indicated on the top left of the top sphere.

10) Change the colour to black and using 20% Opacity again, darken the area
indicated on the bottom sphere.

11) Set Opacity on the Palette to 100% and choose a blue on the edge of the
palette. Using Paint -> Fill -> Plain fill the background. Use Paint ->
Paint with a small brush if the fill does not get all areas, particularly
any overlap that you got when doing the Lighten and Darken.

12) Set Sprite -> Transparent to the same blue that you used to fill.

13) Using Sprite -> Cut -> Rectangular cut out the two spheres in one
sprite. Grid lock should still be active enabling you to cut right at the
edges of the spheres.

14) The sprite will appear in the Sprite pool. Give it a name, spheres.

We are now going to create a cube.

15) Select white from the Palette and click on Process -> Clear Screen to
clear the screen to white.

16) Ensure that you have the Cheetah sprite selected.

17) Using Sprite -> Distort drag out a distort box 4 by 4 units (start from
3 squares in and 3 down - ignore the half square at the top) and using
Adjust drag the control points to provide the shape of the area marked A in
Diagram 3 in the magazine. When you click Select the Cheetah is plotted into
the area.

18) Do the same for the area marked B and E in the diagram.

19) Click on the Vertical Sprite Flip icon to flip the cheetah vertically
and then use Sprite -> Distort to do areas C and D.

20) Set Draw -> Style to do filled areas.

21) Toggle the Frisket icon to Create Frisket - the solid square.

22) If a Frisket is set (shown as areas of red) do a Process -> Clear Screen
to remove it. You must do this anyway when doing steps 30 to 32.

23) Select Draw -> Line.

24) Bring up the Palette and click on Set Frisket, the red colour , there
will only be red or white cross hatch to choose from.

25) Now draw around area D by clicking at the four corner points. Grid lock
should still be on. The area should turn red indicating that a Frisket has
been created.

26) Click on Process -> Invert Frisket and now the only area visible should
be area D. This is the area that will be affected by the next process.

27) Toggle the Frisket icon to Frisket Active - the diagonal lines.

28) Apply Process -> Filters -> Darken with a value of 50%.

29) Repeat steps 22 to 29 but on area C instead of area D and use a value of
35% in step 29 instead of 50%.

30) Repeat steps 22 to 29 but on area B instead of area D and use a value of
25% in step 29 instead of 50%.

31) Repeat steps 22 to 29 but on area E instead of area D. This time you
need to do a Process -> Lighten with a value of 25%.

32) Toggle the Frisket icon to Frisket Inactive.

33) Set the line thickness in Draw -> Style to about 10 and the style to
outline only. Using Draw -> Line draw a horizon line in a blue (drag out the
line and use Adjust to finish the line) as indicated on Diagram 3 from the
edges of the cube to the edge of your window.

34) Use Paint -> Fill -> Plain with the same colour as the line and fill
above the horizon.

35) Turn the grid off by pressing Ctrl G on the keyboard.

36) Select Paint -> Fill -> Angled and also tick the Dither option in the
Fill menu. Note that clicking on a menu item with Adjust selects the item
but leaves the menu on screen. Now select Paint -> Blends number 4.

37) Fill the filled area at the top by dragging the fill arrow from the just
below the top of the canvas to the horizon line.

38) Select Paint -> Blends number 3 and click on the Blends flip icon so
that the Blend runs light to dark. Drag the fill arrow from the left of the
cube to the bottom right of the canvas as shown in the diagram.

39) Ensure that Spheres is the current sprite (the one showing in the pool).

40) Click on the sprite in the pool and place the spheres on the bottom half
of the canvas as shown on the final image.

41) Try doing the same but using different sprites for the different faces
of the cube. You can also create and use your own sprites.
