In MapInfo® the size of points (Symbols) are given in “Points” on the screen. In MicroStation it is necessary to know the size in master unit (feet, meters, etc.). To make this conversion, the script uses a variable named MIF_POINT_SCALE, which contains the factor with which to multiply the point size to get the master units size.

Example: MID_POINT_SCALE = 1.5

MapInfo® symbols with the size 12 points get the size 18 master units. MapInfo® symbols can be defined in several ways. Normally the points are characters in the font named “MapInfo 3.0-compatible.” In this font, the character with number 35 is the asterisk. The script tries to convert the points to cells. The variable MIF_SYMBOL_CELLLIB can be defined to point to the cell library containing cells with names matching the MapInfo® character numbers. The script comes with a cell library containing cells similar to the MapInfo® symbols, with the right names.

Example: MIF_SYMBOL_CELLLIB = 'mapinfo.cel'

If the script cannot find a cell with the right name, a zero-length line is used as the point.
