-- Introduction --
Mandelbrot for Windows allows you to view the Mandelbrot set in one or more
windows under Windows 3.0. Scaling and zooming the image are supported, and
the drawing parameters of an image can be saved to disk so that the image
can be redrawn later.
To install MBW, copy the files MBW.EXE and MBWHELP.HLP to a directory on your
hard disk, then use New Program Item in the Files menu of the Program Manager
to install MBW in one of the group windows.
For help on using the program, read the online help available under the Help
menu.
-- Version 1.2 Changes --
Version 1.2 contains the following fixes and enhancements:
* Earlier versions did not "zoom" accurately -- the drawing parameters were
passed to the new window with only six digits of precision.
* MBW now accepts the drawing parameter file name on the command line. This
allows you to associate drawing files to MBW using the File Manager.
* A few bugs involving the zoom box have been fixed.
* MBW now takes advantage of the 32-bit math instructions of the 386 to per-
form calculations faster.
* A new mode has been added which allows you to view just the Mandelbrot set
itself, with none of the divergent colors displayed.
-- Thoughts, Gripes, and Caveats --
I do not yet have access to a system with a 256-color display, so MBW has
not been tested on such a system. I had assumed that the dithering abilities
of Windows would take advantage of the full 256 color palette without any
special effort on my part, but from what I've read in letters I've received,
that does not appear to be the case. So it looks like I am going to have to
create a 256-color palette myself, and perform my own dithering. Yuck!
The "bitmap" save feature still has not been implemented because, frankly,
I am at my wits end regarding device-independent bitmaps (DIBs). I cannot
make them work!!!! On the rare occasion when I seem to be able to success-
fully create one in memory without getting an "Unrecoverable Application
Error" box, the SetDIBitsToDevice function refuses to display it. I am sure
I am doing something stupid, but the Windows SDK documentation is not much
help.
But I will not be brought to my knees by this gooey GUI. I want to under-
stand Windows inside and out and become an expert Windows developer and make
gobs of money. I shall be victorious!!!
-- In Closing --
I find the Mandelbrot set quite fascinating, and plan to continue to refine
MBW. If you spot any bugs, or wish to make any comments or suggestions,
