Convert code to display Panoramas using old-style PTViewer Java applet

[Hans Loepfe]

Hello,

my client has a ton of panoramas displayed with the old PTViewer.class Java applet, often using the PTRoi.class

Just about since Java updates from JRE6 to current JRE 7.25 the display of these panoramas is no longer possible.

The message says: Security Settings have blocked an untrusted application from running.

I am requested to propose solutions to make them panoramas publicly visible again.

Yes, I know we could run all Panoramas through the 'Publish to Website' option in PTGUI.

But we're hoping for a possibly simpler solution only because the 'Publish to Website' does not yet allow to process multiple source files with varying parameters.

It is also important to retain the current HTML-code (apart from the section displaying the panorama) because it contains other valuable metadata such as titles, descriptions, captions, location info, dates, rights, authorship, file-name etc.. All that data can be made available in a flat csv-file.

Your ideas and suggestions are most welcome, thanks.

Below is an example of the 'old' code:

Hans.

Hi Hans,

One option would be to use Publish to Website and have it only generate
the image tiles. This can be done in batch: panorama.jpg will be
converted to panorama_00.jpg to _14.jpg in the same folder. Then edit
the html files by hand (which is probably unavoidable anyway).

And I'm sure something similar can be done using Pano2VR.

Kind regards,

Hello Joost,

thanks for your  prompt reply.

I know that Publish to Website will create x-panoramas in batch-mode.

We briefly talked about a possible extension of that service recently. (see also this thread on 2014-05-13: https://groups.google.com/forum/#!topic/ptgui/YGw6Eqw1UgI 
I am afraid that as of today your suggestion is the best and only way.

Is it correct that the 'old-code' as indicated in this post (using an applet) is not possible to convert due to security restrictions in JRE 7.x ?

I am looking forward to finding the panorama batch processing that inlcudes panorama specific metadata like title, description, location info, etc. (about 10+ fields).

Greetings, Hans.
