Hello ,
I need create a textDot conduit c#, I set like this;
TextDot dot = new TextDot(dir ,center);
dot.FontHeight = 25;
e.Display.DrawDot(dot, System.Drawing.Color.White, System.Drawing.Color.Black,
System.Drawing.Color.Black);
This is ok , I need to put the background with a solid color, in this case it is possible to see the lines.
Any way to do this?
There are various stages at which you can draw. I think that if you override DrawForeground in your display conduit, you should’ve able to draw on top of everything else.
https://developer.rhino3d.com/api/RhinoCommon/html/M_Rhino_Display_DisplayConduit_DrawForeground.htm
Can you post your complete code of the display conduit?
I have making test on this piece of code, is mess ok’:
namespace StCam.Conduits
{
class GcodeConduit : Rhino.Display.DisplayConduit
{
public GcodeConduit()
{

var rs = (IRhinoScript)rhinoscript_object;
//get todos os objectos
var objs = rs.ObjectsByType(4, false);
if (objs.ToString() == "")
return;
foreach (var item in objs)
{
if (rs.IsObjectHidden(item))
{
continue;
}
var tool = rs.GetUserText(item, "tool");
if (tool.ToString() != "")
{
SetLineColor(tool.ToString(), item, e);
}
var dir = rs.GetUserText(item, "angulo");
if (dir.ToString() != "")
{
double sentido = 0;
if (double.Parse(dir) == 0) { continue; }

Ok, I see that you are drawing all geometry in DrawForeground. I have created a small example conduit to do what you want, see below.
The idea is that you draw geometry in PostDrawObjects and then anything that needs to be on top of everything else in DrawForeground. In the DrawForeground the depth-testing is off.
public class Conduit : DisplayConduit
{
protected override void PostDrawObjects(DrawEventArgs e)
{
e.Display.DrawPolyline(new[] { new Point3d(0, 0, 0), new Point3d(10, 0, 0), new Point3d(10, 10, 0), new Point3d(0, 10, 0), new Point3d(0, 0, 0) }, Color.DarkGreen, 3);
base.PostDrawObjects(e);
}
protected override void DrawForeground(DrawEventArgs e)
{
// don't do this
//e.Display.DrawPolyline(new[] { new Point3d(0, 0, 0), new Point3d(10, 0, 0), new Point3d(10, 10, 0), new Point3d(0, 10, 0), new Point3d(0, 0, 0) }, Color.DarkGreen, 3);
Point3d c = new Point3d(5, 10, 0);
TextDot dot = new TextDot("hello", c);
e.Display.DrawDot(dot, Color.White, Color.Black, Color.Black);
base.DrawForeground(e);
}
}
