[BlindMath] Graphics analyzer for the blind.

[Ray McAllister]

Hi.  Did you know that the blind can draw? With some knowledge of coding, in
whatever computer programming language, you can command computer graphics by
typing in instructions.  I've made pictures, and even 3-minute animated
videos. With your knowledge of math, you can do even more, as a lot of this
relies on a good knowledge of trig.  If you know how to work with fractals,
you can make great plants and landscapes.  

 

And, sometimes it's good to be able to produce graphs in math for
assignments or to show students if you're tutoring or teaching.  Tables of
values work for personal things, but a colored graph is best in other
situations. 

 

But what is hard to do is check over your work to know if what you coded is
what appears on the screen.  You still might want a friend to proof it
eventually, but I've written a simple program that may help weed out a lot
of messes.  

 

I have a graphics analyzer for the blind.  You load into the program a pic,
bitmap, jpeg, something like that.  Then, there are many ways you can search
it.  You can jump to any pixel coordinates.  You can search for a pixel of
any rgb (red green blue) value, or range of values, as you'd search a word
processor document,  forward and backward.  You can also "go" in any degree
direction to find either changes in color or a specific color or range of
colors. 

 

I even have a file of about 500 colors with rgb values.  This lets you hit a
hot key on any pixel and, instead of the rgb values read off, you'll hear
the closest estimate of the actual color, plus the rgb values of that color.
The program uses the internal speech engines in your computer.  

 

I don't plan to really charge for this, as it's a simple program, but I
could find ways of offering it for free.  I wonder, ghough, if anyone would
enjoy playing around with this program, to see how they like it, or how it
could be improved.  Unfortunately, I don't know the super-fast languages,
and it's in LB Booster BASIC, so really huge pics can have a slight delay
when doing pixel searches, but I use this program all the time for my
graphics work, and it works great.  I suppose you could analyze photos or
whatever, if you think that would be interesting. 

 

So, just reply to me here, and we'll figure out where to go from there.
Since Outlook often doesn't like code being sent, even in a zip folder, I
might have to change the file name extension and you can change it back,
but, we'll see what we have to do.  

 

 

Write soon,
