The BTACTILE format (Biblos Tactile)
Tactile graphics can be saved to a file. The format in which they are saved is called Biblos Tactile, with BTactile extension. This format is a simple UTF8 text.
BTactile files can be inserted into documents as normal images. The tactile graphs you insert into your documents are managed using the image properties (Insert menu/Images/Image Properties...)
From the properties, you can vary the size of the tactile graph image in the document, so that it can also be printed in ink with the rest of the document. In addition, you can manage the tactile part of the graph, the one that can be printed in tactile.
