//! a class for handling standard ISO128 and ANSI Y14.2 line types and their dash
|
|
//! patterns
|
|
//! ISO standard lines are defined by a sequence of graphical elements as in
|
|
//! the dotted line (line type 7): DOT, GAP
|
|
//! each graphical element (DOT, GAP, DASH, etc) has a standard length in units
|
|
//! of the line's width.
|
|
//! the graphical elements and line definitions are stored in csv files.
|
|
//! ANSI lines standards are not numbered, but we assign a number as a convenient
|
|
//! reference.
|
|
//! ANSI standard lines are defined similarly to ISO, but the element lengths
|
|
//! are defined in mm, and do not vary with pen width.
|
|
//! ASME standard lines do not specify the element lengths at all, so we have
|
|
//! chosen values generally equal to those for ISO128
