- - - - UTIL Menu Help - - - -
The UTIL Menu can be used for a number of purposes.
First, however, realized that although the interface that this
menu presents is similar to that of the REPP menu, only the F2
option area is an activatable area. In other words, the F3 and
F4 entries are only data for the option you select while in the
F2 area. Once in the F2 area, thirteen different functions are
available. Be aware that some of these functions require that
an image already be <In Save Area> (i.e., have been loaded into
memory).
The option you desire is selected using the arrow keys and
activated with RETURN or F2. Any other F-key can be used to
get out of the F2 function.
Press any key to continue ...
SCRN
The Available Functions:
00: Load Image or Slideshow File. This option takes the file
specification located in the F4 area and, if an .IMG file,
a ReadMAC or a supported Bload-type file, displays the
image. If a SlideShow script, the script is enacted.
01: Show Image in Save Area. After an image has been placed
<In Save Area>, it can be redisplayed with this function.
02: Save Image in .IMG Format. This option takes the file
specification in the F3 area and creates a .IMG file from
the image in the Save Area.
03: Invert Curr Image Top/Bottom. This flips the image in
the Save Area vertically.
04: Invert Curr Image Left/Right. This flips the image in
the Save Area horizontally (makes a mirror image).
Press any key to continue ...
SCRN
More Available Functions:
05: Convert Curr Image->Palette 0. This just displays the
current Save Area image using Palette 0.
06: Convert Curr Image->Palette 1. And this displays the
current Save Area image using Palette 1. This is usually
a better selection than simply using 05.
07: Logical Cvt BW/Pal.1->Pal. 0. This function logically
converts the gray shadings of Black & White and Palette 0
images into a 5-color Palette 0 image. The image to be
converted must be <In Save Area>. The fifth color, black,
is obtained by dithering red & green for the interference.
08: Convert Color Image -> B/W. This function does a simple
convert of a Save Area image to Black & White. Some
conversions may not yield particularly good results.
Press any key to continue ...
SCRN
Yet More Available Functions:
09: Save Image as Standard BLOAD. Instead of saving the image
in the Save Area as a .IMG file, it is saved as a straight
BASIC BLOAD. This means that any color information will
be lost. A proper file specification must be in the F3 area.
10: Load TRS Model 4 HiRes Image. The TRS 80 Model 4 image is
loaded using the file specification in the F4 area. Each
5th & 6th line-pair is combined to compress the 240-line
image to 200 lines.
11: Print Image OKWriter/ML92-93. This option takes the image
in the Save Area and prints it on an Okidata(R) printer that
supports Okigraph(R) graphics. This is a goody for folks
that do not have PC-compatible graphics printers. A dip-
switch setting in an 82A with OKWriter(TM) roms may need to
be set to ML92/93 line-feed mode for this work properly.
Press any key to continue ...
SCRN
Yet Even More Functions:
12: Clean Up Printer Art/Text. This is the only option that
does not work with bit-image files. For this option, F3
contains the name of an input file, and F4 contains the
specification of an output file. This function then makes
one pass of the file in F3 to analyze it, and then converts
it into a clean text file using the file name in F4.
In other words, this functions as a general text scrubber
with usage outside the realm of .PIC file cleanups.
With this option, the following conversions are ALWAYS done:
Tabs are expanded to blanks.
Premature ^Z (end-of-file) characters are made spaces.
Press any key to continue ...
SCRN
The following conversions, however, are prompted-for and
are optional:
Leading Blank Lines can be removed. This can shorten
a printer art file and cause better centering.
Trailing Blank Lines can be removed. This can save
disk space and, for printer art, cause better centering.
Leftmost common blanks can be removed. If all lines in
the F3 file have a number of leading blanks, these can
be trimmed. Again, this saves disk space and leads to
better centering for printer art files.
Lines' Trailing Blanks can be removed. This saves
disk space and leads to better centering of art files.
Press any key to continue ...
SCRN
High Bits (bit 7) can be turned off. Useful with
WordStar(R) files and files that have been corrupted.
Control Characters less than 20h (i.e., space) can be
converted to spaces. Only BACKSPACE, TAB, LF, FF and CR
are permitted to remain. Again, useful with trashed
files or files with transmission errors.
An Example of UTIL288 usage:
On the distribution disk is a file called DRAGON.IMG, a picture
of a rather bored-looking dragon. Unfortunately, the dragon is
upside down. The following will get the .IMG file, invert the
poor dragon, and save him (or her?) in an upright position:
Press any key to continue ...
SCRN
Press F4 and key DRAGON. Hit RETURN (the .IMG suffix is supplied
automatically. Press F3 and key DRAGON2. Again, the file exten-
sion is supplied.
Now Press F2. Since the selected option is already "Load Image",
just press RETURN. DRAGON.IMG will be loaded and displayed.
After the display finishes, press any key (other than F9/F10) to
get back to the Menu.
Press F2 again, and use the arrow keys (which wrap, top/bottom,
by the way) to select "Invert Curr Image Top/Bottom". Press
RETURN. The Image will be inverted.
Get back to the Menu and press F2 again. Select "Save Image in
.IMG Format" and press RETURN. DRAGON2.IMG will be saved.
By now you get the idea. Try re-loading DRAGON2 for practice.
