Copying Previews to All Images?

[twade]

To all,

Is there a quick way to copy all the previews of one image to all the remaining opened images?  It gets pretty tedious dragging the Preview tab from one image to the next.

Thanks,

Wade

Sounds like a good idea.  Hell, i did not know you could drag a preview from one image to another.  Thanks for the lesson!

Hi Wade,

Use the 'preview' command. For example, the following command:

preview -new -x=10 -y=20 -w=400 -h=250 *

will create a new preview on every open image. Each preview will have its top left corner located at image coordinates x=10px y=20px, and its dimensions will be width=400px and height=250px.

Enter 'help preview' to see a list of all available arguments and options.

Juan,

Use the 'preview' command.

Thanks for the tip; however, I don't think this is going to save me any time. 

Here's what I'm doing.  At the beginning of the session, I create the three previews on an image.  I then open up three more images and drag these previews to each image.  I work on each image one at a time.  I save and close each image once their edits are complete.  Before closing the last image, I open three new images and drag each Preview to each newly opened image.  I repeat this process numerous times.

Is there a way to save the preview commands (e.g., similar to a script) so I can run them as soon as I open three new images?  This would prevent having to scroll back through the command window searching for the original preview commands.  What happens if the Previews already exist on an image?  Do I get duplicates?

Thanks,

Wade

Wow... I just typed "help" (alone) and I'm very surprised There should be a tip of this on the starting sequence output on the console.

You can define an alias for the preview command. For example:

alias mypreviews "preview -new -x=10 -y=20 -w=400 -h=250 *"

would create an alias command 'mypreviews' that is equivalent to the example preview command in my previous post. Now each time you run:

mypreviews

what is executed is the sequence between double quotes above (the aliased command).

Another option is creating an environment variable. For example:

export P="preview -new -x=10 -y=20 -w=400 -h=250 *"

creates an environment variable P. Now you can simply enter this command:

$P

and the value of P is sent to the console, running the same command as before.

To make an alias or a variable permanent (i.e. automatically created each time you launch PI) you can add the corresponding commands to your startup.scp script, which you'll find on the bin installation folder.

What happens if the Previews already exist on an image?  Do I get duplicates?

Yes, new previews are created with the same dimensions and coordinates. The platform ensures uniqueness of preview identifiers by adding suffixes (Preview01, Preview02, and so on).

Hope this helps!

Hey Carlos,

Yes, the command line interface has grown a lot since a few versions. There are new commands in version 1.6.1 (hash, lsimg, lsws, lskwd) that I'll describe on the Release Information board, along with all the new features.

Juan,

You can define an alias for the preview command.

The alias is working perfectly.  Your help is greatly appreciated.

Yes - control of PI via the Console is a subject that could have an entire book written about it, and it alone.

I find that I am using the Console far more now that I have it permanently visible on an auxilliary monitor.

Inspired by this post, I wrote a simple script that can be useful. See here.

Best regards,

Awesome!  I'll give it a try when I attempt my next time-lapse this Winter, assuming I get a clear sky.
