    Lots of good information. Could be organized/formatted a little more clearly. Needs a table of contents.

    1. Thank you for the feedback Ill organize it

  2. I really like this Drawing Module, and I've tested it and it works. The thing is, just recently, I've encountered this problem where the images that are being attached end up getting stored as blank images. I know this because when I view the form, instead of showing the stored image, it just shows a blank canvas. I also checked, "C:/Users/<user>/AppData/Roaming/OpenMRS/complex_obs", and I have .png images with the name, drawingObs_<number>, where the max number is 100. However, majority of the images is blank. I'm using multiple editors in my form (4 to be exact). And yes, the IDs in the drawing tags are unique. Would you know what is causing this error?

    1. Sorry for the delayed response.Can you please file a bug with the exact repro steps so that I can look into it.

  3. Thanks so much for the response! I looked into the Drawing Module Repo, but didn't find the link that would allow me to file a bug report. Did you want me to file the report in the OpenMRS Trunk project? Cheers!

    1. For Now please file the bug report in trunk project and add the link in github. Ill try to the drawing module to JIRA

      1. Thanks! I've just submitted a bug report: https://tickets.openmrs.org/browse/ERR-652 If my description, and so on, are unclear, I'd be happy to provide clarifications. You may also get in touch with me at: masarapmabuhay (at) gmail (dot) com. Hooray!
