Image Editor DA v0.65 Demo
by Mike Bergman
Copyright 1988
WARNING: This program only works in high resolution monchrome.
Attempts to use this on a color system is futile...but it won't
crash anything! Maybe later versions will support medium
resolution...
Purpose : To provide tool to edit monochrome .IMG files for
desktop publishing and related activities.
There are no less than three DTP programs and a "draw" program
that incorporates .IMG files and two scanners that have an
optional save funtion to .IMG format. Degas and Degas Elite file
formats have become the standard for the Atari ST which weakens
the capabilities of the end-user. Degas Elite is limited to
640 x 400 dots per file whereas the .IMG format is only limited to
35,535 x 35,535 dots per file regardless of the resolution or the
number of colors used.
The accessory allocates a block of memory on start up. The block
is used to hold brushes, fills, files and the actual image in
machine-specific format which is why the accessory scrolls as fast
as it does. The default setting is 100K bytes. The default can
be changed by installing a file called IMAGE.INF which hold an
ascii representation of the number of kilobytes to be allocated.
For instance, if "200" (without the quotes) is saved in the file
then 200K bytes will be allocated.
Keycommands:
F1 Pencil Allows you to draw freehand. If the tip of
the pencil is on a black pixel it will draw
white. If it is on a white pixel it will draw
black.
F2 Brush There are twenty brushes available that enable
the user to edit the picture with pattern
overlays within the brush area. The brushes
can be selected by pressing <ALT> a and
toggling through the "attributes".
F3 Fill 36 Standard Atari fill patterns can be used.
The patterns can be "locked" where the fill
pattern will remain the same regardless of the
position of the window or the image in the
window, or it can be "unlocked" so that
patterns can be offset.
F4 Eraser A pure eraser. By selecting <ALT> 1 an 8x8
eraser is activated. By selecting <ALT> 2 a
16x16 eraser can be used. By selecting
<ALT> b the eraser becomes an inverted eraser
that erases white pixels from a black surface.
<ALT> w changes it back to a white eraser.
F5 Lines Allows the user to draw straight lines. The
line pattern or line width can be changed by
toggling through the attributes.
F6 Ellipse Hollow ellipses can be formed with this
function. Circles can be made by pressing the
<ALT> key while pressing the left mouse
button.
F7 Boxes Hollow rectangles can be formed with this
function. Squares can be formed by pressing
the <ALT> key while pressing the left mouse
button.
F8 Polygon Polygons with 63 sides can be made with this
tool.
F9 Magnifier Sections of an image can be magnified by a
factor of 2, 4, 8, 16 or 32 by pressing
<ALT> 1-5. To leave the magnifier, press
<Return> or click on the closer box or fuller
box.
F10 Not Implemented.
All tools are implemented by pressing the left mouse button and
stop when the left mouse button is released with the exception of
the Polygon and the Magnifier. By pressing the left button a
corner of the polygon is fixed in place. Release the left button
to move the next side. Press the right button to close the
polygon.
Esc, Undo Erases the last command permanently.
<ALT> o Restores the original image. All editing to
that point is lost.
Arrow Keys Scrolls 25 pixels at a time. The window
arrows scroll one pixel at a time. Paging
moves the images half a page at a time.
<ALT> s Saves the image. The original .IMG file is
saved as .BAK (not implemented on the demo
version).
<ALT> r Reverses the image's colors.
<ALT> a Allows the user to set attributes of the
lines, fills and brushes. This is similar to
the command mode in UNIX vi. It suspends all
editing activities until the user presses
<Return>. Each attribute can be accessed by
pressing the left and right arrow keys. Each
attribute can be changed by pressing the up
and down arrow keys on the cursor key pad.
This is only a demo version. The "Save" function does not work
and you can only look at .IMG files. The "full" version will
allow you to load MacPaint and Degas Elite (uncompressed and
compressed) files and save them out to .IMG files. Also, an
"Undo" function is implemented in the full version.
The full version is available from me for $25. My address is
at the end of this document.
"Full version" is a misnomer. You may find the keycommands
to a little harder to use than drop down menus. Also, the tools
are somewhat primative (but a damn sight better than Super
Charger) and more powerful tools may be needed.
This will not be the final version of Image Editor DA. The
next version will have dialog boxes and pattern menus and some
additional tools but I do not expect to finish it before the 1st
of March. It is likely that the next version will be a commercial
product that will sell in the neighborhood of $40.
However, anyone who buys this now will be entitled all
versions of the DA up to and including the first commercial
release for a nominal cost (i.e.: send me the original disk plus
return postage). This offer expires 31 January 89.
