Multiple Background Mtext

Hi everyone,

I have an issue that I need help with. Here are the details:

I created a command to make the background of multiple MText objects. However, after running this command, all the text merges into a single line. I would like to keep the original positions of the text. How can I achieve that?

[CommandMethod("QM")] public void ApplyBackgroundMaskToMTexts() { Document doc = Application.DocumentManager.MdiActiveDocument; Database db = doc.Database; Editor ed = doc.Editor; PromptSelectionOptions pso = new PromptSelectionOptions(); pso.MessageForAdding = "Select MText:"; SelectionFilter filter = new SelectionFilter(new TypedValue[] { new TypedValue((int)DxfCode.Start, "MTEXT") }); PromptSelectionResult psr = ed.GetSelection(pso, filter); if (psr.Status != PromptStatus.OK) { ed.WriteMessage("\nNone Object selected."); return; } using (Transaction tr = db.TransactionManager.StartTransaction()) { SelectionSet sset = psr.Value; foreach (SelectedObject selObj in sset) { if (selObj != null) { MText mtext = tr.GetObject(selObj.ObjectId, OpenMode.ForWrite) as MText; if (mtext != null) { mtext.BackgroundFill = true; mtext.BackgroundScaleFactor = 1; mtext.BackgroundFillColor = Color.FromColorIndex(ColorMethod.ByAci, 1); mtext.ColumnType = ColumnType.NoColumns; mtext.Width = 0; mtext.Height = 0; } } } tr.Commit(); } } }

Yes, if I don’t set the maximum width and height, some background areas and Mtext might be redundant

Bạn hãy lưu giá trị width trước khi thay đổi mtext

Yes, I repaired it like this, but it still combines into a single line

Add the UseBackgroundColor=false.

if (mtext != null) { mtext.BackgroundFill = true; mtext.BackgroundScaleFactor = 1; mtext.BackgroundFillColor = Color.FromColorIndex(ColorMethod.ByAci, 1); //mtext.ColumnType = ColumnType.NoColumns; //mtext.Width = 0; //mtext.Height = 0; mtext.UseBackgroundColor = false; }
