Once you have created some sort of bitmap image of your own design,
using either of my sets of procedures, you will need to be able to view
it, possibly manipulate it, or print it.

Some image editing programs use virtual memory and some do not. Any image
that you create using my software, that is large enough to require the use
of virtual memory to be rendered, may not be openable within a graphics
editor that does not use some sort of swap file.

Check your BBS(s) to find Windows graphics editors and try them out.
It is a good idea to have a few good ones, because they all do similar
things, but in very different ways. Some of them are able to work on huge
bitmaps with relatively good speed of manipulation. Some are not. Some
available shareware programs were written using the graphics handling 
features built into whatever language they were written in, and therefore,
may be limited. Try to find a top-picks-in-shareware type of list. There
you will probably find a very good one.

Also, my set of procedures for palette bitmaps makes it easy to create
palettes of 256 of any of 16.8 million colors, in any order, regardless
if the system has a true color video card. If your system has a palette
video card, then the total number of possible colors that might be elements
of a palette (as it appears on the monitor) is only 262,144. As it works
out, the red, green, and blue values still have a range of 0 to 255,
but only every fourth number (64 discrete values between black and full
intensity for each r,g,b) is recognized as a different shade on the screen.
Your palette card will display any combination of red, green, and blue values 
to the nearest possible color. Similarly, you may view true color, 24 bit per 
pixel bitmaps in a temporarily color reduced fashion. Only 256 different
colors (out of possibly hundreds of thousands) will appear on the screen at
one time. They usually do not look near as good as they would on a true color 
video system, but at least, you will be able see an approximation of the
image.

Also, it is important to note, that a palette video card can only 
display 64 shades of gray from black to white. Any real shade of gray, that
has absolutely no tint of color to it, is derived by equal values of red,
green, and blue. Black is 0, 0, 0. White is 255, 255, 255. A perfect mid tone
of gray would be 128, 128, 128. Even though a gray scale bitmap is an 8 bit
per pixel type, it requires a true color video card to be able to accurately
display all 256 shades of gray from black to white.

If an 8 bit per pixel bitmap is opened and then saved from within Windows
Paintbrush the palette will be rearranged to conform to windows 256 color
mode. The 10 first and 10 last palette indexes will be changed to a default
set. This process may eliminate many of the colors you may have defined,
and will change the order in which the colors appear in the palette.

CA-Realizer, itself, uses the Windows approach to defining a palette
and handling the color monitor display. The function of any of the graphics
features built into CA-Realizer depends very much on what type of video
card driver was loaded with Windows, and what it is capable of displaying.

BMP Tools For Powerful Computers does not use any of the predefined
graphics features of CA-Realizer. It could, theoretically, work perfectly 
well even with a monochrome display card (if such were possible in Windows).
