display images cause bug

hello,

 

I tried your examples  : https://marvinjs-demo.chemaxon.com/latest/examples/example-more-images-immediately.html

 

it works but for several molecules, the image is not displayed.

I attach the examples in the attached file.

I try marvinjs 14 and 16 and i have the same problems.

Thanks

Hi Kiet, 

I cannot reproduce this issue with the molecules you sent, and it seems that to give you the proper support, we would need more information.

- Could you send us the source of a molecule and a code snippet that you can reproduce the issue with?

If you used MOL V2000 format for the molecules (as these are in the example) please, consider that this format contains 3 lines in its Header Block:
1. line: molecule name,
2. line:  info about the source generation ( if you generated the molecule in Marvin JS this will be something like this: MJ<version number>)
3. line: comments
, and all of the three lines are required (but can be empty).

Please check that all of the 3 lines are represented, because if these are not, Marvin JS could not parse these molecule sources.

I am looking forward your reply here or in email ([email protected]).

Best regards, 
Eszter 

Hi ,

 

the problem come from V3000 format which is not displayed:

Hi Kiet, 

If you applied the example, I assume you used the ImageExporter.molToDataUrl(value) function.
This only works with Mol V2000 format.
For Mol V3000 format we recommend you to use a renderer as you can see in this example: https://marvinjs-demo.chemaxon.com/latest/examples/example-create-image.html . /> (Please note, that for exporting images from other formats than Mol V2000 or MRV, MolConvert web service is needed.)

Best regards,
