<p>Extracting the image data from a PDF is not the tricky part.
Although some displays will support it and some won't, software
exists that can extract images from PDFs into other formats which
can be sent to the display. That is unlikely to be the limiting
factor.</p>
<p>However, the images that you have described may not work well
when imported automatically. Print music can use small changes to
symbols for important differences in the result. This means that
you would probably have to zoom in very much to see the detail,
making each individual symbol quite large. I wouldn't be surprised
if the 10 by 32 line display on the Monarch was only displaying
three symbols across and two down by the time the symbols could be
felt with enough accuracy, and that might not even be three notes.
Zooming out on that image would probably shrink the musical
symbols so much that they're very hard to tell apart. There are
some types of graphic that does not adapt well to low-resolution
displays. That would be fine if you're trying to learn the shapes
of the symbols, but it would probably cause annoyance if you were
trying to learn the music that way.<br>
</p>
<p> In the case of printed sheet music, I think converting it to
Braille music is likely the more reliable answer. It can be
tricky, but software exists to convert sheet music to a format
like Music XML with OCR, and that format can be converted to
Braille. The multi-line display will make that easier to read than
a one-line display, and the density of information will be higher
with Braille than it would with graphics. The software that
converts music to Braille doesn't, as far as I know, support
eBraille yet, but you can arrange it for an embosser with 32-cell
lines and 30-line pages for the Monarch. The Graphiti would not
support that as well.<br>

Yes I have seen it. This is an off shoot of University of
Michigan and was<br>
called the Holy Braille. If you do a search you can
probably find a video<br>
on it. It runs on Air and the under lying technology
has a rubber mat<br>
like material that pushes up pins. It can run on a air
pump or CO2<br>
cartridge. It has micro vacuoles that open and close to
move the pins up<br>
and down. I like how compact the material is and I have
helped with some of<br>
my knowledge in the past . I have my worries about its
power source but they<br>
are showing the technology now and it can be resized to
make larger<br>
displays. I say the more types of technologies out there
the better. <br>
