Daniel, you really need to learn at least to read the braille letters. In
fact, if you would learn the European computer braille numbers as well, you
could read DotsPlus, and it would be a whole lot easier than puzzling out
standard characters. You can learn these in a day. You can experiment with
font size, but my guess is that with something like Areal font (no serifs),
you'll need a font size of at least 40 and probably later. Even then it's
really hard to tell things like a lower case "a" from a lower case "o".
I hadn't realized that you knew absolutely no braille. You really do need
IVEO Daniel.
I have a number of comments below too.
Good luck.
John

Thanks Jonathan and John for the responses,
Firstly, I won't need braille labels for some time as I do not read braille,
so this might make it easier for my support worker and myself to print
correct diagrams.
So if I understand correctly in most of the case th ebest is to put the
picture in a Word file extend itt o full size and with text boxes and the
needed labels in latin symbols. Actually, I am curious: How can you expand
the picture to full size using JAWS?
JAG: Word allows you to change dimensions of an image. If your cursor is on
an image, press the context menu key and press the Format Image item. The
image dimensions are given, and you can expand them to full page. I do this
fairly seldom and have to re-learn it every time, but I have certainly done
this.
Though this might be the best solution, as far as I understand it is
possible to print from other software as well such as R. So in theory I
could print some graphs I produce with Python? What I usually do if a graph
is needed that I try to code it in Python and save it as a image file such
as, png, jpg, or svg.
Thanks for the tipp about the contrast, I will keep that in mind if
something like you described happens.
JAG: If you can make SVG files using Python, my strong suggestion is to open
it in IVEO Creator and let IVEO do its magic. Then you can feel the graphs
and read the text in audio.
Also not sure if I got it fully with regards the font size:
If I want to lets say print a label ont he axes saying e.g. x (m), and t(s),
in latin letters and not braille, what is the size I should use? Is it 30?
An other question with regards texture and line width:
Firstly can a sighted person adjust the line thickness and style of a
diagram using the tss before printing a graph that was produced with some
other program?
JAG: Daniel, you don't need TSS to print graphs unless you want TSS to
translate text labels in MS Word, or perhaps use it to translate Excel
graphs. For other graphs, you are just using the printer driver. TSS is
primarily of interest because of the braille translationor and for the Tiger
Designer, which is unfortunately not usable by a blind person. Until you
want braille translation, forget about TSS.
You need to expand the graph so it is as big as feasible, then just print
it. The bit map text will be printed just like everything else. If the
graph was very small, the text might be enlarged enough to be readable, but
that is rare. But you can adjust the line thickness. There are controls in
the
Tiger Tab. Experiment with them.
Also now I understand the 3 different height of dots depends ont he
darkness. However, is there a way to specify shaded area textures within TSS
or again it has to be done while the diagram is made.
JAG: Daniel, Max has eight sizes of dots actually. Right now, shaded areas
need to be specified when the graph is made. ViewPlus is developing a new
technology that gives you a lot more flexibility however, and it is
something that a blind person can control. It should go into beta test
within a few months. Wanna test it?
Thanks,
Dan

Hi Dan, I can add a bit to Jonathan's comments. There are lots of things
you can do all by yourself, but it will be a lot faster to get just a bit of
sighted help. If you know exactly what the sighted help is supposed to do,
they are a lot more likely to help you. Jonathan is right that you can run
the embosser, but some software manipulation to get the image into good form
is not something a blind person can always do. If you do have IVEO tools,
there are many things you can do by yourself, but again, sighted help is
lots faster.
First of all, understand that the Max is an embosser with a very intelligent
printer driver, but it is not magic. The printer driver can convert a
visual image into a tactile image so that dark things become big dots and
light things become small dots. White is no dots. It can convert ViewPlus
BrailleASCII fonts to braille equivalents, permitting sighted people to see
ASCII characters on screen. The Max does not convert text to braille
however, and I recommend strongly you try using the TIGER29 fonts, which
convert to DotsPlus braille. I promise you that you can read it, and there
is no conversion.
One big hint. If you emboss graphs and find a textured background, it means
that the graph is printed with a slightly off-white background. In the
Tiger Tab there is an undocumented feature called contrast set at 0 by
default. Set it at 1, and off-white backgrounds then emboss with no dots.
You can just leave it set at 1, because the effect on anything else is
negligible.
Finally, for most existing graphics, Jonathan's advice about Word is
correct. Paste the image into Word, stretch to maximum size (you can do
this yourself actually), and then have a sighted person overlay any bit map
text with a Word text box. Try having them use Tiger29 font set a point size
29. It should work just fine. If you do want "real braille", they should
use any standard font, but big, say size 30. Then use Tiger Formatter to
translate. One can put MathType equations above and below the graph if you
wish, and it will also be translated. However you can also read math
equations in DotsPlus just fine too.
Good luck.

Hi Dan,
I've just taken possession of an EmBraille and am also investigating its use
with graphics and braille at the moment.
I've already use Tiger embossers to get images out of R and I'm pretty
confident that I could do the same out of other software without having to
take the images through other software, whether that be using TSS in a Word
document or the IVEO viewer etc.
The graphs I generated do not have braille of course. They are just the
visual image bashed out on paper, but there was plenty of information in the
content of the graphs I've tried thus far without the text being readable.
In particular, I want to know that a label has been printed where I expect
one to be when I take the image and put it in a document for the sighted
world.
If you want braille in the images, then you will need a human to intervene.
They'll need more than the TSS to do this. IVEO creator for them and IVEO
viewer for you.
So, my advice is to get some of the software you'll use, generate some
images and then emboss them using the Tiger. If that means taking someone
from the department to the place where the embosser is so that you can test
it then perhaps that is what you'll need to do.
If you want to have a tactile version of the images someone else is making
then try the above, but be prepared to put them into a Word document if you
don't have the right software.
It seems to me that you will have more trouble with the software used to
make the images than the embossing process. Depending on the software you
need to test I may be able to help. I'll soon have a ViewPlus Premiere 100
on the network at work and will get others to send images from software I
don't use. I can probably track down a few physicists if needed but
mathematicians are easier for me to come by. Send requests to me directly in
that case at a.j.godfrey at massey.ac.nz
Good luck.
Jonathan

Subject: [Blindmath] Tiger Max braille embosser
Hi all,
My university just bought a Tiger Max braille embosser. It should also come
with the Tiger Software Suite.
Could you please give me some advice how to use it efficiently for producing
diagrams needed in physics and mathematics?
The embosser is going to be used by myself for purposes of printing
mathematical figures and an other blind person mainly for printing braille
text.
As I have never used any embosser and have a very limited knowledge on them,
I am asking for your experiences and technical tipps. I am really new in the
topic of creating tactile figures using an embosser.
May be a few explicit questions to get started:
1. Can I produce diagrams 100% individually using the software and a
screen reader? Not necessarily by producing them directly on TSS but lets
say import from an svg or pdf file? Or I will still need someone to adjust
graphs from a file to a tactile print view?
2. What can the software do? Is it only for settings of the embosser
or it is a sort of editor for image sas well?
Many thanks,
Dan
