- -- 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!!!
