PostScript is a very widespread vector graphics description language. It was introduced by Adobe more
than twenty years ago. It is not a kind of static description like a list of vertices and lines (cf. VRML),
but a true language, allowing the author/generator to ask the interpreter (often in the printer) to
perform complex tasks.
Encapsulated Postscript is a superset of PostScript adding some extensions to facilitate the inclusion
of PS pictures inside documents. It mostly adds a preview feature as a bitmap representation of the picture.
Several formats are allowed, and a portable one is preffered. Arabeske uses this portable format.
The reasons for having EPS export in Arabeske are that, first, Arabeske is basically a vector drawing
software, allowing its output to be resizeable at will. Another reason is that some converters accept EPS
as input and generate DXF, which in turn can be used in most mesh-based 3D CAD/rendering software.
Arabeske needs a good knwoledge of what lines and surfaces have to be exported before outputting to EPS. This is why this exporter can be used only in "Final" and "Interlace" modes.
To run the exporter, select , then choose the filename. The default output file extension, if this feature is enabled, is ".eps". Click Export: that's all!
The way bitmap textures are handled desserves some precisions.
The system is exactly the same as the one
Arabeske uses for screen display of textures: it tries to "perfectly" scale the textures, tiling them if
they are much smaller than the picture, and resizing them as little as possible. But as EPS is a vector
format, Arabeske needs to make some assumptions about the "size" of the output. It assumes that, for small
textures, the resolution is 72 DPI. If you want to use sharper textures, use tiles with big dimensions.
Note that for technical reasons, the size of your tiles is limited in EPS export. But the maximum size is
about 21000x65000 pixels, which should be enough for most situations.
