Polyline
zgf_type: zgf_polyline
ZGF line features specify linear features defined by a sequence of x and y coordinates.
These attributes are specific to line features.

zgf_line_type |
An integer code describing the appearance of the line. Range: 1 - normal line 2 - dashed line 3 - bold line 4 - hachured line 5 - hachured line 6 - double dashed line 7 - triple dashed line Default: No default |
zgf_smooth |
The smoothing flag. |
zgf_continue |
This flag specifies whether or not the polyline was constructed from multiple smaller segments, as stored in the ZGF file. Range: 0 - stored as a single, standalone line 1 - stored as multiple line segments Default: 0 |
zgf_line_width |
The width of the line. Range: 32-bit real Default: No default |
zgf_first_dash_length zgf_second_dash_length zgf_third_dash_length |
For dashed lines, these denote the length of the dashes. Range: 32-bit real Default: No default |
zgf_first_dash_gap zgf_second_dash_gap zgf_third_dash_gap |
For dashed lines, these denote the length of the gaps. Range: 32-bit real Default: No default |
zgf_hachure_direction zgf_hachure_spacing zgf_hachure_length |
These are used to specify the presentation properties of hachure lines. |
zgf_marker_number
|
For normal or boldface lines, if zgf_marker_number is not 0, it specifies the symbol that should be drawn at each point on the line. Range: 32-bit integer Default: No default |
zgf_marker_height |
If zgf_marker_number is specified, zgf_marker_height denotes the height of this marker. Range: 32-bit real Default: No default |
zgf_color_index |
An index to the color table owned by the feature’s containing MGU. Used to find the feature’s color. Range: 0 - 255 Default: No default |
zgf_units |
Indicates the natural coordinate space for the feature. Note that all coordinates are converted to user space by the ZGF reader. Range: 1 - user (also called application, engineering, or scaled) 2 - plotter (also called unscaled) 3 - normalized (all coordinates between 0.0 - 1.0, inclusive) Default: No default |
