Art For Art’s Sake

There are literally hundreds of Art applications available for home micros, ranging from simple doodlers to complex suites offering solid 3D animation; the choice is bewildering. So what features should you look out for when buying one for your machine? Andy Storer paints a picture of the perfect pixel package…

How many colours in the spectrum?

Whether you’re paying £3 or £300, most art programs provide a system of pull-down menus and icons for moving between the screen painting area and palette and painting tool control. This is absolutely essential, since you’ll want to be able to move quickly through the range of colours on hand and the painting ‘surface’ before you.

A good program will allow you to flick back to a full screen painting area after changing tools, operations or colours from an overlaid control panel. The more advanced packages will offer you the choice to scroll through a much larger area of work than can be displayed on screen at any one time or, alternatively, have a number of screens in memory that you can flick between.

Although you can buy packages for mono systems, most on offer are designed for colour. Obvious really. Painting’s all about colour isn’t it? Well, up to a point. The point being that you don’t need thousands of colours to produce effective artwork. The number of colours available to you will initially depend on the resolution your machine’s able to support and the degree to which the software allows mixing of the standard colours and combining them to form composite hues and shades.

But more sophisticated software can actually address the hardware to change the screen-scanning to display a new palette of colours on every line. Thus, for instance, Quantum Paint on the ST can offer 4,096 on-screen colours despite the ST offering only a choice of 16 from a palette of 512.

For general purposes, however, 256 colours is the most you’ll ever need – beyond that it becomes difficult to distinguish them. The best packages will offer you a full screen palette which displays all available colours, rather than a simple palette bordering it, thus allowing you to select the one you wish to use simply by clicking on it.

Pixel Picassos

The beauty of electronic painting is the ability to continually modify your work without having to start all over again. Whilst a package will offer you the obvious option of a variable sized eraser, alterations are often likely to involve finer tuning than rubbing out whole areas.

So, for instance, once you’ve chosen a colour and done some drawing you will be able to change it simply by selecting a shade from the palette you wish to replace it with. Ideally, you should be able to click on any individual pixel of colour you’ve painted and be given its exact RGB code so that subtle alterations can be made.

In addition, it’s useful to have a ‘cycle draw’ option where you may select a range of adjacent colours to be painted in sequence as a brush line is drawn. In this way you can subtly blend colour to produce graded hues. In this respect it’s also useful if you can individually alter the hue and luminance of any particular pixel or area by simply clicking on a relevant icon.

The ‘front end’ control panel will allow you to choose between the range of painting tools on hand. A good package should offer you not only different pens, brushes, sprays and fills but a range of shapes, transformations, preset effects and texts. For freehand drawing, mouse control is infinitely preferable to the joystick or keyboard, assuming you don’t have a graphics tablet, and the range of pens and brushes should allow you a choice of line thickness, tip size and style.

Ideally, rather than preset sizes and shapes, you should be able to step up or down through a range. Likewise, sprays should also offer variable density and offer a choice of pattern, flow and nozzle type. The option to fill enclosed areas of artwork with a range of preset patterns is also essential, as is the ability to design your own fills.

Such design may require a fair degree of detail, so a facility allowing a graded zoom magnification of any area is also essential.

Ideally you should be able to grab any part of a screen and use it as fill for another and also merge, or ‘dither’, two adjacent fills so that a perfect gradation is apparent.

Getting into shape

Image005a

Any art package worth its salt should allow you to zoom into an area of the screen for detailed work. Even an average package will offer a zoom of 16x magnification.

Another feature worth looking out for in art packages is the ease with which it is possible to call up perfect circles and ellipses of varying size and thickness for exact positioning in the work area. Advanced packages will also allow you to smooth the curvature of a circle or ellipse to remove its jagged edges.

Of course, you’ll want to be able to construct other shapes, not all of them regular, and in this case you should look for a package that allows you to form multi-sided polygons. Creating the exact shape you desire is likely to be a process of hit and miss, so it also essential to have an ‘Undo’ function.

The most sophisticated features available to the pixel painter are block manipulations. Standard packages offer the facility to define sub-screen areas and move or copy them to other parts of the display. Middle range products will allow you stretch, skew, rotate and distort such defined blocks, whilst the more advanced will not only provide the tools to mirror, flip and invert the image-block but also make it opaque or transparent. It should also be possible to smear a specified area so that it appears to have been dragged. In addition, a more comprehensive package will allow you to outline and frame specified areas with a range of borders and define shadow depth and direction effects.

What can I get out of it though?

Unless you wish to incorporate your artwork into a program or game, then you’ll be wanting to produce hard copies of your masterpieces. The simplest way of achieving this is by photographing the screen. For this you’ll need a 35mm camera with a variable shutter speed which will allow you to shoot slow enough to avoid screen refresh lines in mid-scan. It’s best to shoot in a darkened room with the aperture wide open at a speed of 1/8 or l/4sec.

Colour printers aren’t much cop unless you’re prepared to fork out the readies, so the only other recommended way of displaying your work is by transferring it to videotape. A composite video lead between your micro and the video’s input should do the trick quite easily.

There’s always more…

This overview has concentrated on the options offered by paint packages and takes no account of related features, often incorporated, such as sprite construction, animation and 3D modelling. Express will be covering these areas in the near future.

Write then, let’s go

The inclusion of a text facility is also essential so that you may annotate diagrams or drawings. Here, you should look out for those programs which offer a range of text and font sizes and also include options to vary density and add outline, underlining and skew.

Finally, you should be able to save whole or part-screen files in a compressed form to save on disk space, and also be able to save and load palette and paint tool selections as new default values.

Graphically Superior
