Hi, We tried to do this Code:
float tmpLine = (float)lpX.Value;
Aurigma.GraphicsMill.WinControls.LineVObject lpLine = new Aurigma.GraphicsMill.WinControls.LineVObject(tmpLine, 0, tmpLine, _workingMultilayerViewer.WorkspaceHeight * 72);
lpLine.Pen.Width = 0.1f;
lpLine.Brush = null;
PointF[] test = GetTransformedCornerPoints(lpLine);
_workingMultilayerViewer.Layers[0].VObjects.Add(lpLine);
private System.Drawing.PointF[] GetTransformedCornerPoints(Aurigma.GraphicsMill.WinControls.VObject obj)
{
System.Drawing.RectangleF baseRect = obj.GetVObjectBounds();
System.Drawing.PointF[] cornerPnts = new System.Drawing.PointF[4];
try
{
cornerPnts[0] = baseRect.Location;
cornerPnts[1] = new System.Drawing.PointF(baseRect.Right, baseRect.Top);
cornerPnts[2] = new System.Drawing.PointF(baseRect.Right, baseRect.Bottom);
cornerPnts[3] = new System.Drawing.PointF(baseRect.Left, baseRect.Bottom);
obj.Transform.TransformPoints(cornerPnts);
}
catch (Exception ex)
{
}
finally
{
}
return cornerPnts;
}
We found that, when tmpLine = 22.6768 Test Point will be + [0] {X = 22.6768 Y = 0.0} System.Drawing.PointF + [1] {X = 22.726799 Y = 0.0} System.Drawing.PointF + [2] {X = 22.726799 Y = 612.0} System.Drawing.PointF + [3] {X = 22.6768 Y = 612.0} System.Drawing.PointF Wondering why the value for X are not all the same? We did check on some other numbers like tmpLine=28.346, it gave no issue @ all. Please advise.

Ching-Yen, It is not issue. You use GetVObjectBounds() method to get bounds of the line vector object: Code: System.Drawing.RectangleF baseRect = obj.GetVObjectBounds();
Therefore, you get a bit different values from right side. The difference is 0.05. I checked tmpLine = 28.346. And got Code:[1] {X = 28.396 Y = 0.0} System.Drawing.PointF
[2] {X = 28.396 Y = 612.0} System.Drawing.PointF
