Hi,

I used JChem Manager to create a structure table. Then through JChem
Manager I imported .SDF file into the table.

Now I want to display a structure as
an image in the browser for a particulr cd_id.

Any .NET
example would be much appreciated.

Thanks

Hi,

if you install JChem .NET API you will be finding an Examples folder there under e.g.:

C:\Program Files\ChemAxon\ChemAxon .NET versions\Examples\ASPNETExamples\Sample

here there is a document how to

C:\Program Files\ChemAxon\ChemAxon .NET versions\Examples\ASPNETExamples run the web demo solution.

Here are some files from that folder how to render molecule on the web:

Code snippet:

            var molecule = new JChemMolecule(new MoleculeData(moleculeString, format));
   StructureDrawingInfo drawingInfo = new StructureDrawingInfo();
            drawingInfo.Size = new Size(width, height);
            molecule.Renderer.Settings = new JChemMoleculeRenderingSettings(drawingInfo);
            return molecule.Renderer.RenderToImage(ImageFormat.Bmp);

These cs files contains the most commonly used ChemAxon.NET molecule services.

The MoleculeImageHandler.ashx.cs is the one that I was looking for.

Thank you

Is there is a way
upon drawing an image to change its background color? It currently
renders in black.

I think you might have problems with the transparency property ...

Have you checked the .NET API as I suggested there you will get smaller demo codes running on local host (document also exists how to set it up) and you will see that you do not get black moelcules.

It was coming out black until I set the transparency:

bmp.MakeTransparent(Color.Magenta) '--Magenta in bitmap will be transparent
