Drawing a polygon 6 years 7 months ago #12848
|
Good day, please advise me how to draw a polygon using the latest library version.
This is what I currently have Page page = m_doc.GetPage(vpage.GetPageNo()); page.ObjsStart(); Path path = new Path(); path.MoveTo(100, 100); path.LineTo(120, 100); path.LineTo(120, 130); path.LineTo(110, 120); path.LineTo(100, 130); path.LineTo(100, 100); path.ClosePath(); int color = 0x99ff0000; page.AddAnnotPolygon(path, color, color, 200); page.Close(); path.Destroy(); it should look like a bookmark icon but it looks very strange with lines going all over the place

You are setting a 200 as stroke width (very big):
using the following code you obtain the correct shap: Path path = new Path();
path.MoveTo(100, 100);
path.LineTo(120, 100);
path.LineTo(120, 130);
path.LineTo(110, 120);
path.LineTo(100, 130);
path.LineTo(100, 100);
path.ClosePath();
int color = 0x99ff0000;
page.AddAnnotPolygon(path, 0xff000000, color, 2);
If you want it upside down: Path path = new Path();
path.MoveTo(100, 130);
path.LineTo(120, 130);
path.LineTo(120, 100);
path.LineTo(110, 110);
path.LineTo(100, 100);
path.LineTo(100, 130);
path.ClosePath();
int color = 0x99ff0000;
page.AddAnnotPolygon(path, 0xff000000, color, 2);
