nldaisy@robobraille.org
Produces a full Daisy project complete with audio with
a user response in Dutch.
To produce a Daisy project, submit a Word document (.doc, .docx, .xml or .rtf) to one of
the accounts above. The author and title of the document must be specified in the
document meta data, and the first element in the document must be a level heading 1.
The Daisy accounts are implemented using the Daisy Pipeline. The TTS is selected via the
main language attribute of the submitted document. The current implementation of Daisy
Pipeline does not support changes in the natural language of a document, nor is it
possible to change the speed of the generated audio. The audio speed can often be
adjusted in the Daisy player.

Daisy Math accounts
Account
Function
daisymath@robobraille.org
Main Daisy Math account. Produces a full text, full
audio Daisy project of documents that may contain
math or other scientific expressions.
This is an experimental function that is currently limited to American English. Other
languages are expected to be added during 2013.
To produce a Daisy project with math or other scientific notation, the math or science
notation must be created using the MathType editor from Design Science in Microsoft
Word, and the document must subsequently be stored as a .docx file. RoboBraille uses
SaveAsDaisy and the Daisy Pipeline to create the Daisy project. Use of the built-in math
editor in Microsoft Word is not supported.

into tagged pdf, web projects or rtf files subject to the format specified by the user in the
subject line, e.g., pdf, html or rtf. Text files in the old DOS format (with .asc extension)
are converted into corresponding Windows text files. Pdf, tiff, gif jpg, bmp, pcx, dcx, j2k,
jp2, jpx, and djv files are converted into the format specified by the user in the subject
line of the mail, e.g., pdf, htm, txt, rtf, doc, docx, xml, xls, xlsx and csv. In case the
target format for this latter conversion is doc, docx or rtf, RoboBraille will attempt to
remove optional hyphens from the result.
Note: It is usually not a good idea to convert a tagged pdf file into tagged pdf. As all pdf
files are subject to OCR processing, any accessibility features and/or semantic markup
already present in a tagged pdf file may be erased in such an attempt.

It is possible to change the base line of the text, i.e., the text size of the body text. This
feature may be used to adapt e-books for people with low vision for reading in
commercial e-book readers. While many e-books have a base line of 10 or 12 points,
RoboBraille makes it possible to increase this base line to 16, 24 or 40 points using the
following parameters in the subject line:
Base line parameter
Base line effect
Large
Move base line to 16 points
XLarge
Move base line to 24 points
Huge
Move base line to 40 points
Note that not all a-book readers recognize changes to the base line.

Formatting and embossing documents
RoboBraille includes a number of facilities to convert character sets, format and emboss
Braille documents. Internally, RoboBraille uses the OctoBraille character set, a Braille
variant of the standard Windows 1252 character set also known as Latin 1.
4.1
Converting to the character set of the embosser
If your Braille embosser is capable of formatting, word-wrapping and paginating Braille
documents, then you may only want RoboBraille to return your document in the Braille
character set that your embosser uses, and let the embosser handle the rest. To do that,
simply specify the Braille character set of your Braille embosser in the subject line of
your mail to RoboBraille. In RoboBraille terminology, such a character set specification is
called an export filter. The table below lists the export filters currently supported by
RoboBraille:

The character set will then be added to RoboBraille when the system is next updated.

Formatting your document
To format your Braille document to a particular paper format, you can use a special
export filter called format. Along with the keyword format, you need to specify the
requested page width, page length and whether you want your document paginated, in
the form formatXXYYpwhere XX specifies the number of characters per line, YY the
number of lines per page and p pagination. The use of p is optional. The table below lists
the formatting options currently supported by RoboBraille:

RoboBraille when the system is next updated.
The figure below illustrates how to specify that the Braille should be returned by
RoboBraille formatted to 40 characters per line, 25 lines per page with pagination:
In many cases, you will need both formatting and conversion to the character set of your
Braille embosser. In such cases, you will need to go through two steps:
1.
Transcribe and format your document by submitting it to an appropriate Braille
account (say, sixdot@robobraille.org) specifying the formatting details in the subject
line (e.g., format4025p).
2.
Convert the resulting document to the correct Braille character set by submitting it to
export@robobraille.org, specifying the export filter in the subject line of the email.
4.3
Using Portable Embosser Format
Portable Embosser Format – or PEF – constitutes a standardised way of embossing Braille
documents, and is the recommended format for Braille produced by RoboBraille. Based
on XML and Unicode, PEF is a document type that represents braille pages in digital form,
accurately and unambiguously; regardless of language, location, embosser settings,
braille code and computer environment. It can be used for Braille embossing and
archiving anywhere in the world, no matter where nor how it was produced.
RoboBraille uses a special export filter called pef to render Braille in PEF. Along with the
keyword pef, you need to specify the requested page width, page length, whether you
want your document paginated, and whether you want duplex printing in the form

pefXXYYpd where XX specifies the number of characters per line, YY the number of lines
per page, p pagination and d duplex. The use of p and d are optional, and either one can
be used irrespective of the other. The table below lists the pef options currently
supported by RoboBraille:

If your paper format is not included in the list above, please send an email to
contact@robobraille.org with a specification of format. The format will then be added to
RoboBraille when the system is next updated.
The figure below illustrates how to specify that the Braille should be returned by
RoboBraille in PEF formatted to 40 characters per line, 25 lines per page with pagination
and duplex printing:
Similarly, the RoboBraille web interface can be used to the same effect by selecting
pef4025pd as the target format:

The result from RoboBraille is an xml file in Unicode with a .pef extension. In order to
emboss the file on a Braille embosser, you will need an embossing application.
It is also possible to produce a Braille document, conduct minor editing in the result
convert the end result to PEF. In order to achieve this, submit the document to the
appropriate Braille account without specifying an export filter (or by using a format-
filter), edit the result in a text editor and finally submit the edited Braille document to an
export-account with the requested pef format in the subject line. The example below

20
shows how to convert an already transcribed Braille document into PEF, formatted to 33
characters per line, 29 lines per page with pagination and duplex printing:
RoboBraille recommends the use of the freeware Easy Embossing Utility, developed by
the inventors of PEF. The PEF Easy Embossing Utility supports most available Braille
embossers and can be downloaded from the following link: www.pef-format.org. As an
alternative, the Daisy Pipeline includes a script for embossing PEF files.
Once installed, files with the .pef extension are associated with the PEF Easy Embossing
Utility and double-clicking on a pef file will open the interface to the utility. The first time
the application is launched, you will need to specify the brand and model of your Braille
embosser, the paper format and the Braille character set used by the embosser.
In addition to embossing, the PEF Easy Embossing Utility also features a preview option.
In order to view the contents of a PEF file in a text editor, it may be necessary to install a
Unicode font that includes the Braille range of characters. An example is the Code2000
shareware font that can be downloaded from the web.
The figure below shows the main interface to the PEF Easy Embossing Utility.
