Show Absolute lables in .NET Marvin View control

Hi,

I have a problem with the Marvin View control. How i can activate the stereo absolute lables so i can see the "Absolute" in the structure image?

Thanks,

Tobias

Hi Tobias,

 

would you like to do it from code?

 

Viktor

Yes. 

Just because right mouse click over the control and say properties, the display settings contains the Absolute  Stereo flag, this can be set to true.

From code:

            var viewer = new ChemAxon.NET.Windows.Forms.MarvinViewControl.MarvinViewControl();
            viewer.MoleculeData = mData;
            viewer.Settings.AbsoluteLabels = true;

            var viewerForm = new System.Windows.Forms.Form();
            viewer.Dock = System.Windows.Forms.DockStyle.Fill;
            viewerForm.Controls.Add(viewer);

            viewerForm.ShowDialog();

I tried it with 

 this.marvinViewControl.Settings.AbsoluteLabels = true;

Now i see the label in the editor, if i double click the viewer. But in the viewer i don't see the Absolute label.

What happens if you use right mouse menu over the viewer control?

I see the Absolute label on top. The image of the structure is bigger than the view control.

The same problem i have if i use the molecule renderer:

StructureDrawingInfo drawingInfo = new StructureDrawingInfo(new Size(width, height));

drawingInfo.StructureDrawingSettings.AbsoluteLabels = true;

JChemMolecule molecule = new JChemMolecule(new MoleculeData(molfile, MoleculeFormat.Unknown));

molecule.CheckNull("molecule").Renderer.Settings = new JChemMoleculeRenderingSettings(drawingInfo);

Image moleculeImage = molecule.Renderer.RenderToImage(ImageFormat.Png);

 

There i don't see the absolute label, too.

Possibly this is a bug, the Absolute label is not rendered properly in the box.

Tobias,

 

as we discussed thorugh mail you used an outdated library (14.xx from last year), which contained the bug, but this has recently been fixed.

This is just a message to other customers as well reading this forum thread, 15.2.x or above to the latest can be downloading if someone wants to use the absolute label property properly.
