This is the program from issue #3 of Amazing Computing, where the following
description can also be found.
NOTE: This programs requires the presence of the file graphics.bmap
DeluxeDraw is a drawing program with many features found
only in more expensive drawing programs. It saves
pictures or brushes in the format used by BASIC for BOBs and VSprites.
One of the advantages of this program over other drawing programs is its
ability to choose high or low resolution. You may choose the number of bit
planes, thus controlling the total number of colors available.
It is written in AmigaBasic and requires 512K bytes of memory.
Deluxe Draw demonstrates many advanced uses of Amiga Basic, including
using functions from the Amiga operating system libraries.
Here is a a short description of the program's modes, and an explanation of
the icons on the screen.
The number of available drawing colors is controlled by the number of
bit planes selected when the program starts. Enter 5 for 32 colors,
4 for sixteen colors, 3 for eight colors, or 2 for four colors.
The leftmost column of 4, 8, 16, or 32 boxes is used to select the current
foreground and background colors. The foreground color is surrounded by a
white highlight, the background color is the previous foreground color.
The foreground/background color pair are displayed in the
lowest box in the second column.
The rightmost column is used to select the drawing styles and to
toggle options on or off. Each selected style or option is
surrounded by a white highlight box. To select an option, click once on the
that box.
The first four boxes, with trapezoids inside, are different brush widths,
from a single-pixel fine brush to a fat eight-pixel-wide brush.
The fifth box, with a brush icon inside, is used to select a custom brush.
This selection lets you frame an area of your picture and use that area as a
brush. Move the mouse to the upper-left-hand corner of the area for the new
brush, and click and hold the left mouse button. Move the mouse to the
lower-right-hand corner, and release the button. If a brush has been
selected, click this box again to discard the brush, and to select another.
The sixth box has an icon of rays radiating from a point. It is used to draw
multiple lines. Select a center point for the lines with the mouse by
clicking once in a spot in the drawing area. Lines are drawn from the point
where the mouse button is first pressed to the current mouse position as long
as the button is held down.
The seventh icon is a tipped-over paint can. This selection is used to flood
fill an area with the current foreground color. The area to be filled is
that area with all adjacent pixels that have the same color as the one where
the mouse button was clicked. Note that this function uses the Amiga
graphics library "Flood" call, instead of the corresponding Amiga Basic
function. The Amiga graphics function operates as one would expect -
a marked area is filled with a color.
The eighth selection is for sizable circles. A circle outline is
rubber-banded between the center where the button is first pressed. When the
button is released, a circle is drawn at that size and location. Its radius
is the distance between that center and the current mouse position.
The ninth box has rectangle inside. This is the sizable rectangle selection.
A rectangle is rubber banded between the point where the button is first
pressed and the point where you let up on the button. The rectangle is then
drawn in the current foreground color.
The tenth icon with a single line is the line selection icon. It draws a
line between the point where the mouse button is first pressed and the point
where it is released.
The eleventh box has a 'T' inside. This denotes the text selection. Simply
click the mouse button where text is to be printed, and type the text at the
keyboard. Note that the text will be printed with the current foreground and
background colors.
The twelfth box which has three horizontal bars in it denotes the red, green,
and blue sliders. Click this box to adjust the currently selected drawing
color. A window with three sliders will appear. These sliders are used to
precisely select the amount of red, green, and blue in the current foreground
color.
The thirteenth box, with a checkerboard pattern inside, is used to toggle
between checker-fill and solid modes. This controls whether
flood fill, lines, rays, and the various width brushes paint in
solids or checks.
The fourteenth box with multiple vertical stripes of color is used to turn on
or off the color cycle mode. The colors between the foreground and
background color are rotated in a cyclical manner.
The fifteenth and last selectable box selects cycle draw. When this is
turned on the current foreground color is rotated through the colors between
the foreground and background colors displayed in the last
box.
