question for export option

Hi

Our chemist would like to see R/S symbol when the structure is exported as an image.

I have not tested e/z option yet, but does it handle R/S too?

If not, is it possible to add it?

Thanks,

yasushi

 

Dear Yasushi!

Marvin is able to export images with R/S labels.
When you use the GUI to export images, you can turn on their visibility at View/Stereo/"R/S Labels". (Deatiled information can be found at: Stereo Specification in Marvin)
When you using MolExporter, you can specifiy the chiral_off/chiral_selected/chiral_all option in the format string. (Further information about format options: Image export in Marvin)

Best regards,

Istvan

Hi Istvan

Thanks, it worked.

I testged with emf image export from MolHandler with toBinFormat method adding chiral_all option and you can see the attached image.  I needed to save the image as png to post it on this forum, but it looks like emf image type is not as sharp as png even if I use te same hight/width.  The line is little edgy.  Is there any way to make line sharper or gives higher resolution?  I am not sure what is causing this problem.

Thanks,

yasushi

 

 

 

Yes, we admit that lines are not so sharp in EMF than in our PNG output. Currently, we use the Freehep API to generate EMF. The same problems exist by OLE copy when the image of the pasted object are generated by the same tool.

We are working on improving EMF quality.

In OLE copy, we will use a native Windows (.NET) solution for picture drawing that will provide better image quality. We plan that this improvement will be ready for Marvin 5.3.

Hopefully, this solution will also solve the first problem (poor EMF by molecule export API). If not, we will research for another solution to solve it.
