- ProArtisan 24 is a 24 bit Art and Painting package for the Acorn Risc PC
- range. It encourages experimentation and allows artistic expression through
- the wide range of tools available that mimic natural media. It also provides
- sophisticated image manipulation facilities.
-
- A great deal of effort has gone into creating a user interface that gives
- access to the power of ProArtisan 24 without making it complex to use. Those
- of you used to ProArtisan 2 will quickly adapt to ProArtisan 24.

-
- Technical Information
-
- ProArtisan 24 is a 16.7 million colour painting package. These colours are
- held as 24 bit values. There is also a 256 level Frisket (or mask). Images
- created in ProArtisan 24 can be any size provided that your machine has
- enough memory. Pictures are ALWAYS stored as 24 bit images (16.7 million
- colours) - we make no compromise for 15 bit and 8 bit modes.
-
- You can work in other modes if you wish but 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 24 to save in another mode.
-
- Warning: Editing images when not in a 24 bit 16.7 million colour mode may
- cause changes that are not apparent until you return to a 16.7 million
- colour mode.
-
-
- What do I need ?
-
- To run ProArtisan 24 you need an Acorn Risc PC fitted with RISC OS 3.5 or
- later, a minimum of 4 megabytes of RAM and 1 megabyte of VRAM. Like most
- applications ProArtisan 24 will benefit from having more RAM and VRAM. Our
- suggested system would be 2 megabytes of VRAM and 8 megabytes of RAM. Having
- 2 megabytes of VRAM is the most important upgrade as this will allow you to
- use an 800 * 600 resolution with 16.7 million colours. Make this your first
- priority. Call Clares for details on discounted VRAM upgrades on 01606 48511
-
- Any of the monitors supplied with the Risc PC will support the 16.7 million
- colour mode at 800 * 600 resolution but we can attest to the quality of the
- 17 inch monitor and its usefulness.
-
-
- Running the ProArtisan 24 Demo
-
- Run ProArtisan 24 by double clicking on the !PA24Demo icon in the directory
- display. The ProArtisan 24 icon will then appear on the icon bar. To open a

-
- Short Tutorials
-
- To get you into ProArtisan 24 as quickly as possible the following tutorials
- introduce some of the basic tools for creating and manipulating images.
- Remember that you can use tools in conjunction with others and it is this
- which makes ProArtisan 24 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 manual. We will try to point out interesting effects
- when appropriate.
-
- The images that we are going to create uses several concepts which are
- central to the ProArtisan 24 philosophy.
-
- Some of the commonly used toolbox functions are briefly described within the
- directory 'ToolBoxes' supplied with this demo.
-
- 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.
-
- Note: When a menu item is written as Frisket => Fill it refers to the
- Frisket menu which is accessed via the Paint icon but only when in Create
- Frisket mode.
-
-
- ---------------------------------------------------------------------------
-
- All the examples assume starting from a clean canvas as if you had just run
- the program. The main Tool pane is shown below to help locate icons.
-
-
- Example 1 - Anti-aliased text
-
- 1) Load the supplied file called Apple.
-
- 2) Go to Draw => Style and set the style to be Filled but not Stroked (A
- solid rectangle without a border).
-
- 3) Go to Draw => Text and select Trinity Bold at a point size of 150. Change
- the text to just read 24 and click on Apply. Click outside the text to paste
- it to the screen and immediately click on Undo.
-
- 4) Toggle the Frisket icon to Create Frisket.
-
- 5) Click on the Palette icon and click on Toggle foreground & background
- (immediately below the Undo button) so that black is background and white
- foreground.
-
- 6) Go to Draw => Path and click on the 24 to paste it to the screen.
-
- 7) Move the outline 24 so that it is all on the apple and click outside the
- path to render it. You should see the 24 in red (the default Frisket
- colour).
-
- 8) Select Frisket => Blur to anti-alias the frisket.
-
- 9) Toggle the Frisket icon to Frisket Active.
-
- 10) Use Paint => Watercolour with the Colour opacity slider set to 70% and
- paint over the apple to reveal the 24.
-
- Try some different brushes instead of the last step or try some Filters and
- Effects.
-
- ---------------------------------------------------------------------
-
- Example 2 - Sunflower - Cutting out complex shapes
-
- 1) Load the image Sunflower.
-
- 2) Toggle the Frisket icon to Create Frisket.
-
- 3) Set Frisket => Add colours to 30% and click Select on the canvas around
- the flower head until all the background is converted to a frisket, leaving
- just the sunflower head.
-
- 4) The centre of the flower head is also likely to be included in the
- frisket so use Frisket => Eraser to erase the frisket from this area. You
- might find it useful to untick the Frisket => Mix item to see the frisket
- more clearly.
-
- 5) Click on Frisket => Invert.
-
- 6) Toggle the Frisket icon to Frisket Active
-
- 7) Ensure that Foreground colour is currently selected and select the bottom
- right colour from the Quick choice palette. This is a special Magic colour
- that is used by the program to fill an area prior to attempting to do a
- Magic wand. If this colour is used as a fill it is treated as being
- transparent by the Sprite => Cut.
-
- 8) After selecting the colour do a Ctrl X to clear the screen.
-
- 9) Use Sprite => Cut => Rectangular and band a box over the flower head
- (keep it tight to avoid wasted memory).
-
- 10) Name the captured sprite in the Sprite pool as Flowerhead.
