The following paragraphs deal with some such solutions. Some, such as Brailletec's Elotype, leave the raster in order to create smooth curves. And some devices now coming onto the market print tactile images directly onto paper using some form of relief generating material. This is, up to now, the easiest and most advanced way to create raised graphics, In each case, software is needed to create the tactile image in the first place. It makes little sense to try and emboss a line drawing without any conversion, as the result will generally be useless due to the low resolution of embossers.
Modern braille editing software can handle embossed graphics.
Programs such as the Duxbury braille translator, the ET graph X, or ProfessionalBraille all support it. BrailleGraf by Brailletec goes a step further, being an object oriented tactile drawing program. A similar approach is the PictureBraille software from Quantum. Ideally, these are combined with text into books. In order to do this economically, it is necessary to use a computer throughout for creating proofs and final versions, and preferably employ the same software for proofing and final version.
