IEC 62665:2015(E) this International Standard specifies:- a text encoding scheme to generate a texture map,- a physical shape and dimension of the texture map for printing,- additional features for texture map printing and- a texture map decoding and an auditory presentation of decoded texts. These specifications enable the interchange of documents and publications between visually impaired and non-impaired people. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. Two different control codes are described by the different terms: "control codes for text" and "control codes for speech". Pack processing and LZSS processing are shown in their additional subclauses. An example of the header file "Speechio.h" is added. An example of error correction encoding is shown in additional Annex D.
