I'm not sure how it is that Value Historian provides access to writing data inside the qtz via input ports from a technical standpoint.
I do know that the image importer patch is prototypical example patch of how to pull in any kind of file or data, and embed it in a qtz. Any data can be pulled in, so long as the extension is an image file type. So, I know there is some kind of mechanism for storing data to qtz via patch, undocumented or not. In the attached composition, if one selects settings on this image importer, and holds down Option while pressing the Import From File field, one can save the "Image Data" to your Desktop (or wherever). Rename the file with a dae extension, and "voila", the qtz was used as a receptacle to hold dae data. One can hold pretty much any info in a qtz using this method. It would be nice to have a "holds any kind of data via input port" sample and hold type patch using some of these principles. EDIT: The message was too big because of the qtz attachment... I simply renamed the sphere.dae from the mesh filter examples as a jpg, and embedded it into a qtz file. One can try this on their own if they wish. -George Toledo On Mon, May 3, 2010 at 5:14 AM, Achim Breidenbach <ac...@boinx.com> wrote: > Hello George, > > the problem I see is that, when you try to save data to the qtz file from a > plugin point of view, you don't have any connections back to your container > file where your plugin instance was originally extracted from.
