draw polylines

void GD2d_draw_polyline
(state, vcount, vert, fcolor, vcolor)
GDstate *state;
int vcount;
SHORT2 vert[];
FLOAT3 fcolor[];
FLOAT3 vcolor[];

Description

GD2d_draw_polyline draws a single polyline; that is, a series of connected lines, although the renderer does not automatically connect the last line to the first.

Here is what a polyline looks like, with the polyline's vertices numbered:

{bmc \\Pcserver1\Public\Doc\Express4.xRefpages_nextRelease\gdapi_build\WINHELP\FH349066.TMP}

You set vcount to the number of vertices.

vert should specify vcount pairs of x and y values.

fcolor should be NULL. Or it should specify a color for each line segment; that is, ( vcount - 1) sets of red, green, and blue values.

vcolor should be NULL, or specify vcount sets of red, green, and blue values.

For details on the parameters, see Common parameters to the GD2d_draw routines .
