Osimis Webviewer has problems with some dcm files
tosch...@gmail.com
I am testing current version of Osimis WebViewer plugin as part of Orthanc 1.2. Good improvements btw.
However, some of my simple test files lead to bad results here and the log indicates that Osimis viewer has problems here. The same files are shown perfectly in Osirix8.
I attach two of my test files with which the problem can be reproduced. The files have been created manually from a jpg with dcmtk tool im2dcm (http://support.dcmtk.org/docs-dcmrt/img2dcm.html)
The problems are
- bad quality of image (even worse compared to the PNG directly requested via Orthanc REST API)
- red bar at bottom of viewer
- indications in Orthanc/Osimis log "low-quality etc."

(Indeed the high-quality images are never loaded.)
We're tracking this issue internally and will report once we have a
resolution.
