molecules as pictures not clear with JChem 3.0.12

Dear Support,





I upgraded JChem from 2.1 to 3.0.12.


But the molecules converted to png are now less clear and sharp with JChem 3.0.12 than JChem 2.1





I use the same code for the two version.

Code:

OutputStream os = resp.getOutputStream(); os.write(MolImporter.importMol(molFile).toBinFormat("png:w100,h100,#FFF5DE") );

is there a way to put the molecules wires darker in the pictures.


Or is my way to create pictures not the proper way?





thank you very much for your help.


Best regards





Jacques

Switch off antialising to get sharper image. See the "noantialias" image export option:

Code:

OutputStream os = resp.getOutputStream(); os.write(MolImporter.importMol(molFile).toBinFormat("png:w100,h100,noantialias,#FFF5DE") );

thank you for your fast answer,





but it seems that molecules even with with noantialias option are still less clear ans sharp the in JChem 2.1.


Are there difference between the generation of png in JChem 2.1 and JChem 3.0.. I guess so, but on the renderer of drawing line and symbols?





Kind Regards,


Jacques

Yes, both molecule cleaning and image export are improved since JChem 2.1.

without using anti-aliasing, are there other possibilities to play with sharpness and clearness of the pictures to be created from the molecules?

I suggest you to play with the size of the images.

By the way, we plan to rewrite line drawing of Marvin. I hope it will solve your sharpness problem.

thank you very much, I'll get back to you when testing the new release of JChem and Marvin.





best regards,





Jacques
