working with previews

[ChoJin]

hello,

I have two quick questions when working with previews:

- is there a way to "scroll" the left vertical tabs with the previews on the side of the image? I often have many of them, and although I know I can use the next/previous shortcut to jump to the next/previous preview, it would be more convenient if I could just scroll the tabs and click on the one I want. Is there a way to do that?

- is there a way to "save" my previews (in the history for instance, or however)?
I'm trying to preserve my history as much as I can to be able to "replay" each step later on if I need to make adjustments (or just review them).
For instance, early in the workflow I define a bunch of previews to aggregate them for my background neutralization and color calibration. I'd like to be able to retrieve them later on if I want to revisit my workflow, but it's annoying to keep all my previews throughout the whole workflow. I therefore would like to "save" them, and then remove them from my active image before continuing my process. Is there a way to do that without having to clone the image (or generate an empty image and just duplicate the previews, which seems like a hack/workaround to me)?

Hi ChoJin!
There is a Script called
PropagatePreviewV2
in
SCRIPTS
   UTILITIES

This copies all or some previews of your original image and or other images in one or more steps 
to another image(maybe you name the receiving image "preview_store")
Dont forget to check  "Preserve existing previews"....

In the vertical Tab 
ViewExplorer
you can select all the "hidden" previews which are vertically stacked "down under"....
and/or you can select them also in the horizontal View Selector below the History Explorer

thanks! I missed the view explorer. I'll try to use it to see if it fits my habits

I knew about the propagatepreview script (that's what I was referring as a "hack" in my initial question), but it's not very convenient, especially considering I've just noticed it seems the previews have the same storing size than the full image when you save the project including the images (is that a bug?!)

You can remove all the previews and continue working with your image. The history of the image includes also all the previews (and their respective history) at any point of the processing of the image. You can always go (with the help of the History Explorer) back to the processing step where you had all those previews. You'll recover all of them and any processing history you had in the previews.

If you want to save all those previews and all the histories, then I recommend you to save a project. In the future, the XISF format will allow you to save all this previews and their histories in a single file, being a kind of "micro-project".

I recommend you reading The Official Quick Guide to PixInsight. All these user interface specific questions -and much more- are covered in the book. If you don't have an Apple device, we'll soon releasing an Android version in ePub format.


Best regards,
Vicent.

  How about a version that I can read on my windows computer--I do not have an apple device or an android phone or device.

Hi,

I think there are ePub readers for PC.

Hi Chojin!
The solution with the project or history explorer does not work when you get back a few steps in the history
to redo your operations again with other parameter values. THAN ALL former "future Previews" ARE GONE!
Copying the History to a ProcessContainer only copies the processes and NOT the previews!

So, for me the only way to save the Previews is PropagatePreviewV2  (Not PropagatePreview  !)
Its not complicated, its only one step no matter how many preview you want to transfer with
one step. 
If you only want to save one preview you drag and drop it to the "preview_store".
If the Previews are disturbing my view to the image i simply make them temporarely invisible with the flipflop
"ShowPreview".

The Previews are only stored with their respective size, means smaller than the total image.
However it would be nice if the Preview creation could be a simple storable process which would need less
storage and would also make it more easy to handle previews.

That's true; if you go back on the history and apply different processes from the former history, the old history is changed with the new processes, starting from the step where you add the new processes. However, he was asking to just go ahead after deleting all the previews in the BN process.

I always save multiple projects every time I process a new image, saving them at specific key points of the processing. You never know, suddenly you have a new idea and decide to start from an specific point in the processing of the image. I don't recommend to save a single project for a given picture.


Best regards,
Vicent.

[ChoJin]

thank you very much for your multiple helps.

For some reasons I don't see the previews in my history. Maybe it's because I didn't use them directly for a process but only for the previewaggregator script.

[vicent_peris]

Do you mean that you go back in the history of the image and the previews don't appear again?
