- 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.
