ZBMP0.97 4Îc-{Q×…A.1. Viewing an existing figure file. Item (2) of Main MENU.
A list of existing figure files, in the current directory is
displayed. Select the desired file by entering its number.

Data on the selected file is displayed and this may be printed
with the PrintScrn key. To print the figure to your H-P LaserJet,
see Item (6) of Main MENU.

If the file is an only partially completed figure, you may elect
to finish it. Otherwise, press any key to display the file and a
Small Menu will appear.

F2 Display just removes the Small Menu. Press any key to restore
the Small Menu.
F4 Zoom produces a box for selecting a subregion of the figure,
to compute and plot. Move the box about with the Cursor keys.
Adjust the size of the box with PageUp and PageDown. To move
faster, use the keys on the numeric keypad. Press Enter to select
a region or Esc to return to the Small Menu. If you select a
region, you will have an opportunity to edit several parameters.
The sequence, from this point, is the same as if you had selected
a subregion of a freshly computed figure and is described below.

F5 Measure produces a cross hair to read the true coordinates of a
point in a figure. Move it about with the Cursor keys. Return to
the Small Menu with Esc.

F6 traces External Rays.

F7 returns to the list of existing figure files. The directory is
not read again, at this point, so any files you have made in the
meanwhile will not appear. To see these, Press Esc, to Return to
the Main MENU, and then select (2) View an Existing File again.
.2. Making a New MSet Figure. Item (3) of Main MENU.
Begin by entering the seven parameters on which the computation
depends.

The desired region of the plane is specified by the coordinates
of the center of the figure, which are ( x_center, y_center ),
and the height of the figure, which is ymax - ymin. The program
determines the width = xmax - xmin of the region so that the figure
is proportioned correctly.

Default values of all the parameters, for the full MSet Figure,
are given on the data entry screen. To accept a default value,
just press Enter, or Enter your own value. See the documentation
for information on the effect of changing these.

After the parameters are entered, select the desired Complement
Coloring Scheme. The main purpose of this program is to provide
(1) Solid Complement and Solid Interior, which results in the
best figure and the shortest computation time. The remaining
schemes are provided for comparison purposes.
Finally, select the desired palette. (1) YABMP Default Palette
should be used. (2) default VGA/SVGA colors and (3) user-defined
palette map are provided for comparison.

The computation of the figure can be interrupted. Pressing Esc
terminates the computation and returns you to the Main MENU,
discarding the partially completed figure. Pressing Enter
terminates the computation, but allows you to save and use the
partial result. Press Esc only once and wait until the current
line is completed.

After the figure is completed, press any key to see the Small
Menu:

F2 Display just removes the Small Menu. Press any key to restore
the Small Menu.

F3 Save asks you for a filename and saves the figure as a file.
If you choose an existing filename, the figure file is not
overwritten, but the figure is saved as TMP_???.BMP.
F4 Zoom produces a box for selecting a subregion of the figure,
to compute and plot. Move the box about with the Cursor keys.
Adjust the size of the box with PageUp and PageDown. To move
faster, use the keys on the numeric keypad. Press Enter to select
a region or Esc to return to the Small Menu. If you select a
region, you will have an opportunity to edit several parameters.
The sequence, from this point, is the same as if you had selected
a subregion of a freshly computed figure and is described below.

F5 Measure produces a cross hair to read the true coordinates of a
point in a figure. Move it about with the Cursor keys. Return to
the Small Menu with Esc.

F6 traces External Rays.

F7 returns you to the Main MENU.
.3. Making a New JSet Figure. Item (4) of Main MENU.
A JSET figure is made in the same way as an MSet figure. The
Small Menu works in the same way as described for MSet figures,
above.
.4. Options Menu. Item (5) of Main MENU.
(1) Select Default Video Mode works in the same way as the
initial selection, when you first run the program, as described
below. You may make the selection permanent, saving it to a new
BMPSCRN.CFG file, or not. You may also use this item to just view
the currently selected video mode, using Esc to return to the
Main MENU.

(2) Check Aspect-Ratio displays a circle inscribed in a square.
Use your screen controls to render the square accurately square.

(3) Load a Palette File from the current directory.

(4) View Palette displays the palette to be used, according to the
choice of color scheme and palette.

(5) Displays the text file YABMP.DOC.

(6) Displays version and author information.

(7) Returns to Main Menu.
.5. Printing an existing figure file. Item (6) of Main MENU.
Only the Hewlett-Packard LaserJet II and III are supported.
Pixels in Color 2, which normally appear on the screen as Bright
Yellow and represent points near the boundary of the set, are
printed. The best printed output is generally obtained by using a
larger value of thickness, than should be used for the best screen
output.

(1) Selects Portrait or Landscape Mode.

(2) Selects printer resolution (300 dpi, 150 dpi, 100 dpi, or 75
dpi). Smaller values of dpi produce larger figures.

(3) Selects the target for the output. (1) LPT1: sends output to
the H-P LaserJet connected as LPT1: (2) PCL File sends output to
the named file. To print this file, use COPY /B. For example,
COPY NAME.PCL LPT1:/B. (3) HP File for inclusion in TeX document.
.6. Batch Mode.
If you Enter YABMP &NAME, YABMP will attempt to read and process
the file NAME to compute, process and save the figure file
specified in NAME.
