INTRODUCTION

Draw256 is the result of my efforts to construct an easily available
and free art package for the PC. It incorporates some of the features
that I have looked for in an art package, usually without success.

Draw256 is one of a handful of non-commercial art packages that I know
of. I hope that it will help fill the requirements of users.


MAJOR FEATURES OF Draw256

It's free.

Draw256 uses loadable graphics drivers. This means that Draw256 can
be modified to work with a different video card simply by installing
the appropriate driver.

Both EMS (Expanded) and XMS (Extended) memory are used, making much
more room for image data.

Images varying in size from one pixel by one pixel to the size of
available memory can be manipulated.

The workspace isn't cluttered. I got fed up with art packages that
filled the screen with icons, leaving only a small space in which to
draw. In Draw256, the entire screen is the workspace. Instead of
distracting icons, almost every command is available with a single
keystroke.

Many art packages require that certain palette entries be left
unaltered, so that their system colours remain intact. Draw256 is
adaptive; from any palette, Draw256 will use the colour that most
closely matches the actual colour it needs at the time. This strategy
leaves all palette entries open for editing, and makes palette editing
simpler.


SYSTEM REQUIREMENTS

Draw256 requires: a 286 processor or higher, a Microsoft or
compatible mouse and mouse driver, a VGA or compatible video card, and
about 500 Kb of conventional memory.

Draw256 will be happier if it is run on a 386 or higher processor. In
this case, it will make use of any available EMS and/or XMS memory.

In order to use the 320x240, 320x400, and 360x480 drivers, a register-
compatible VGA card is required. For most users, this requirement
should not present a problem.


PACKING LIST

The current version of Draw256 consists of the following files:

DRAW256.DOC This file
DRAW256.EXE The program code
DRAW256.CFG The configuration file
320X200.DRV Graphics driver for VGA 320x200x256 mode
320X240.DRV Graphics driver for VGA 320x240x256 mode
320X400.DRV Graphics driver for VGA 320x400x256 mode
360X480.DRV Graphics driver for VGA 360x480x256 mode
640X480.DRV Graphics driver for SuperVGA/VESA 640x480x256 mode

(autodetect)
1024X768.DRV Graphics driver for SuperVGA/VESA 1024x768x256
mode (autodetect)
ANGULAR.FNT Font definition file

If you did not receive all of these files, you have an illegal copy of
Draw256.


RELEASE NOTES FOR v2.21

Draw256 now has much improved SuperVGA support. Notably, the Trident
bug is dead.

Draw256 may exhibit unusual behaviour when it is run under tight
memory constraints. For best results, give Draw256 plenty of memory.


USING Draw256

Although it may be slightly intimidating at first, Draw256 is easy to
use. Simply run DRAW256.EXE, and it's ready.

To draw, hold down the left mouse button while moving the mouse.
Alternatively, you may use the numeric keypad to draw by pressing any
of the eight direction keys while either NumLock is active or a Shift
key is pressed. To draw a single pixel at the current pointer
position, press the spacebar.

To select a new drawing colour, click the right mouse button. Click
the left button on the colour you wish to draw with. To abort, either
hit ESC or click the right button once again.

When images larger than the screen are being worked with, the portion
of the image being displayed can be changed with Ctrl-key
combinations. Ctrl-left moves left, Ctrl-down moves down, Ctrl-Home
moves to the upper-left, Ctrl-5 moves to the center, Ctrl-PgDn moves
to the lower-right, and so on. All eight direction keys and the 5 on
the numeric keypad can be used.

The other keys are reserved for more specific functions. Read on for
a more detailed description.


HELP

For help, hit the F1 key.

AIRBRUSH

The 'A' key will toggle the airbrush on/off.


CHANGING THE IMAGE DIMENSIONS

Draw256 supports images ranging in size from one pixel to the size of
available memory. To change the dimensions, press 'D', then enter the
new width and depth as prompted. Caution: this procedure will
destroy the current image.


EDITING THE COLOUR PALETTE

The VGA's default palette, is, at best, lousy. Draw256 allows you to
edit each of the 256 available colours to your liking. To do so,
press 'E', then select the colour you wish to edit. Play around with
the up, down, left, and right keys; you'll learn the controls soon
enough.


REGION FILLS

Draw256 allows you to fill a portion of the current image with a
colour. To do so, position the mouse pointer in the region you wish
to fill, then press 'F'. The fill routine I wrote will fill, using
the current drawing colour, until a colour other than that of the
region is encountered.


ERASING

To erase part of the current image, press 'K'. When the left mouse
button is pressed, the area inside the rectangle will be blanked with
the current drawing colour.


SAVING AND LOADING IMAGES

Images may be saved and loaded in either Draw256's own .VGA format, or
the .PCX format. To save, press 'S'; to load, press 'L'. Afterwards,
type in the name of the file. (Caution: if you are saving, and the
file you enter exists, it will be overwritten.)

No extension is necessary on the filenames. If none is present, the
default extension will be assumed (See "CONFIGURING Draw256"). If the
extension exists, and is either .VGA or .PCX, the save or load will be
forced to that format.


MAGNIFYING PORTIONS OF AN IMAGE

To activate the magnification feature, press 'M', then select the area
you wish to magnify. During magnification, new colours may be
selected.

To accept the changes made during magnification, press either 'M' or
Enter. To abort the changes, press ESC.


STARTING A NEW IMAGE

To completely abandon the current image and start a new one, press
'N'.


THE PALETTE MENU

To access the palette menu, press 'P'. From this menu, palettes may
be saved and loaded, in either the raw binary .PAL format, or
Fractint's .MAP format. .PAL files are smaller and slightly faster,
but utterly illegible. .MAP files are suitable for editing, and are
much more easily read.


RANDOM COLOURS

If for some reason you wish to draw with the current colour constantly
changing, you may do so. Press 'R' to toggle the random colours
on/off. This option can produce an interesting effect, especially
when used in conjunction with the airbrush.


STAMPS

A "stamp" is a portion of an image which may be easily placed anywhere
on an image.

To cut a stamp, press 'C', then hold down the left mouse button and
move the mouse until the area you wish to use as the current stamp is
outlined.

To write the current stamp, press 'W', then move the mouse and click
the left button wherever you wish to place the stamp. Click the right
mouse button or press ESC when finished.

To access the stamp menu, press 'T'. Cutting and pasting are
accessible through this menu, as are saving and loading of stamps.
Stamps may be stored on disk in either Draw256's .VGA format or the
.PCX format.


EXITING Draw256

To exit Draw256, press ESC.


DOS SHELL

To shell to DOS, press F10.


CONFIGURING Draw256

Draw256 comes ready to use. However, several changes may be made by
editing the file DRAW256.CFG with a text editor. There are two types
of lines in DRAW256.CFG: comment lines, which have a semicolon in the
first column, and configuration lines, which consist of, in order, a
valid configuration directive, some whitespace, and a valid parameter
for that directive.

Valid directives are:
GRAFDRV The filename of the graphics driver to be used
FONT The filename of the font to use
DEFAULTPAL The filename of a .PAL to be loaded automatically
DEFAULTMAP The filename of a .MAP to be loaded automatically
DRAWCOLOUR The default drawing colour (defaults to 0)
HORIZMOUSE Horizontal mouse sensitivity, in mickeys per pixel
VERTMOUSE Vertical mouse sensitivity, in mickeys per pixel
IMAGEWIDE The default image width (defaults to screen width)
IMAGEDEEP The default image depth (defaults to screen depth)
IMAGETYPE The default image type: either .PCX or .VGA
(defaults to .VGA)

DRAW256.CFG must include at least one GRAFDRV and at least one FONT
directive.

The mickey is the unit used to measure mouse movement. Smaller
numbers will produce greater sensitivity, while large numbers will
decrease sensitivity.

When more than one of the same directive is present, the last one is
used.
