[Blindmath] SVG figures and embosser

[John Gardner]

Daniel, you are probably right that a contrast setting of 1 was not quite
enough.  Try 10.  If your problem is a slightly gray background, 10 should
be enough to suppress it.

As for a SVG Viewer, you can get IVEO Viewer from the ViewPlus web site, and
it is free.  An SVG that has not been enhanced with IVEO authoring software
will not be audio-active, but it should still print just fine to your Max.
In IVEO Viewer it will automatically scale to whatever paper is set.  You
can also zoom and pan to emboss portions.

Good luck.

Hi all,

 

Not long ago I finally had access to a Tiger Max braille embosser. I was
experimenting with printing out jpg and svg files and had semi-success.

 

The jpg was automatically printed on full a4 size from a picture viewer and
also pasting it in a word file and extending it full page worked well.
However, the disadvantage of this method was a somewhat "dirty" background
around the curve of a function. I remember we have talked about it some time
ago, so looked up the e-mail conversation. I've tried to look up the
contrast setting as mentioned and set it from 0 to 1 but didn't change much.
Not sure though if I was changing the correct setting as this contrast
adjustment could go from -100 to 100. So I guess changing from 0 to 1 didn't
make the difference. Besides jpg files had some strange extra lines on them,
which I didn't expect to appear. This is most likely to be because of the
way they were created rather than the embosser. 

 

Also I tried to emboss svg graphics. Here both the extra unnecessary lines
disappeared and the curve was a clear line without any noise around it.
However, no matter what I just could not open properly the svg file other
than internet explorer and could not make it full size.

 

Is there a good svg viewer where I can also set that it prints out full a4
size?

 

Thanks,

Daniel
