To begin output to a Scalable Vector Graphics (SVG) file. Scalable Vector Graphics files allow you to produce graphics file that are resolution independent.
INTEGER FUNCTION OPEN_SVG1@(FILE, NX, NY, UID)
Calling OPEN_SVG1@ will direct graphics to a new SVG graphics file. SVG has the advantage of being a vector format that will scale with the resolution required.
NX and NY specify the bounding box into which the graphics are to be drawn. FILE is the path of the file. This is
analogous to generating printer output. UID
is the programmer's identifier of the associated graphics object (used in SELECT_GRAPHICS_OBJECT@).
Call CLOSE_SVG@(UID) to terminate output to the file.
