File extension graphics palette
Zx-Spectrum.
Idea: (c) Spark HG (Donetsk)
The scheme: (a) VG Studio (Cherkassy),
Article: (c) Slider / BIS / Rush (Cherkassy).
On numerous graphic extensions of the platform has been said
very a lot. But In very small fraction of these proposals has
taken root. Even if it happened, for various reasons, the next
bloat on Speccy can boast of a few. The biggest problem - a
nonstandard finalization, which is associated with mass
inconvenience. After all, if you write the program, supporting
such an extension, then machines where the signified is not
adapted soft will not work. Of course, You can use
auto-completion, or a prompt. But the second The problem is
that most of these bells and whistles are expensive, use a lot
of chips and, for the most part, impractical.
But here, there is finally something
new. The idea to expand the graphics
palette not zhruschaya additional CPU resources and does not
require additional memory for the on-screen information (Such
as the use of two / three screens) and, most importantly, it is
inexpensive (cost - about 0.3 cents) and does not take a lot of
man-hours spent with a soldering iron at the computer.
In general, it all started with an idea of the creative
team Spark HG. The guys offered take the signal flash, whose
frequency 2Hz and replace this frequency to 7MHz. As a result,
the inverting attribute when enabled bit flash will change its
ink / paper very quickly and thus gain the mysterious mixed
color. But the impracticality of this was obvious - if enabled
flash attribute is completely stained according to color and
ink on paper almost no difference.
The idea immediately received an immediate extension. About
the ways in which Cherkasy hardware'naya studio "VG" came to
final design to tell too long and it is not necessary, since
how important is the final result. AND
he following:
1) When using bit flash attributes are not flashing, and
start to mix Color ink and paper and this color is used only
ink. Paper also takes radical black. Thus,
if the attribute is set, for example,
yellow ink (ink 6) and red paper
(Paper 2), when the bit flash
on the screen you will see in this attribute
black paper and red - yellow, ie,
orange ink.
2) If the colors in the attribute set
on the contrary, ie ink 2 and the paper 6, with
included flash, the color of ink will also be
orange, but different from the previous
case. When mixing is dominated by paper,
and therefore in the first case, ink is
red-yellow, while the second - a yellow-red.
3) And finally, if we use more and
bright, then we obtain more and brightness
colors, which are generally 128 units - of which
128-16 = 112 new.
So, without any incompatibility
with the old software (except that now, instead of flashing
"LOADING" one can contemplate the same inscription, marked in
gray) has been dramatically enhanced color gamut with a
standard screen resolution and memory occupied by it. The only
limitation as you realize this is something that can not
complementary colors to use on colored paper, since it will
still be black (it's like you already knew, it was
done to get more new colors).
Revised scheme given by computer
"Pentagon" (see the OSD file on disk)
but, in principle, can extend ANY
computer because understand the scheme
more or less knowledgeable Th loveku not be
Labour and by analogy can be modified any
machine.
And now a few comments on the revision:
1) If you think that the colors will be
somehow flash (again, as
when working with 2 screens), so you are deeply mistaken - 7MHz
is enough, that they were dead and stable, no flicker or shake;
2) compatibility with the programs, there is complete. And
even in those rare prog that use flash for anything to
highlight, you still see the object selected;
3) to use these advanced color
in practice, as you know, you can
from elementary, at least, the same Art
Studio, selecting the section "Attr" color
who need to mix and adding flash;
4) since the previous description of the use of additional
colours'ov quite uncomfortable, then hasten to bring you good
news Moldovan band Bytex, which makes
Art Works - a new graphical editing
torus, promised to support him in this
develop and make the choice of extended
colors are much more convenient. Also, we
BIS, will try to establish contact with a group of Excess,
creating a graph-editor "Excess de Luxe Paint" and also offer
them to support flash-colour. And as Viator /
Rush, in their new versions of the "Art Studio"
will do it;
5) Unfortunately, the software is not possible to determine,
done Does the computer conversion, so all
will be determined visually using a
test.
And finally a few words. If there is something you
misunderstood, could not do, and so etc., then you can always
