Stone Viewer: ? Scale embedded PDF's, and ? controls for mobile devices.

[Stephen Douglas Scotti]

I've been attaching PDF reports to studies using the RESTAPI, which works fine, although maybe not implemented completely. 

On a smaller mobile device, it looks like embedded .png images actually scale to the width of the viewport, but a .pdf does not.  I've attached a screen capture of the issue here.  Also, seems like the mobile touch screen controls are not working, or I do not know how to enable or use them for the Stone Viewer.

The corresponding DataSet for the PDF Instance is like the following.  Might actually want to change the ISO_IR also, and maybe 0042,0011 (EncapsulatedDocument): Null ?

As indicated in the Orthanc Book in the FAQ section:

https://book.orthanc-server.com/plugins/stone-webviewer.html#faq

"The internal use of Stone of Orthanc library gives us a lot of flexibility to implement new advanced features, such as 3D rendering (MPR, reslicing, image fusion...), DICOM-RT support, storage of annotations/measurements, viewer for mobile devices, internationalization (translation)... We are looking for industrial sponsors to implement such new features in the Stone Web viewer."

Thanks.

Is this important that 0042,0011 (EncapsulatedDocument): Null, be set to something else ?

It is set to Null on Orthanc, although I could probably set it when I attach the instance.  I do that in a Python Plug-in, where Tags are set to:

 query = '{"Tags" : {"Modality":"SR", "Manufacturer": "REPORT", "OperatorsName":"' + query['author'] + '", "SeriesDescription":"' + query['title'] + '","SOPClassUID":"1.2.840.10008.5.1.4.1.1.104.1"},"Content" : "data:application/pdf;base64,' + query['base64'] + '", "Parent":"' + query['studyuuid']+ '"}'

Does  EncapsulatedDocument need to be set as well ?  Also, I have Modality as SR, Structured Report.  Presumably should use something else for that for a PDF, and possibly also populate the SR object.  Looks like Orthanc is automatically changing SR to OT.  I'll have to read up about the SR object:  http://dicom.nema.org/dicom/2013/output/chtml/part20/sect_A.3.html

"Null" is the value reported by Orthanc Explorer for tags whose value is a binary buffer. It does not mean "empty".

Thank you.
