Zoom to the selection

[Guest]

Hi Scripters,

I have been looking for a way to javascript the zoom to fit the selected objects into the window, I have looked through the zoom styles but cannot find one that does this. I have tried the "Fit Selection in Window" menu item in InDesign but this zooms out a lot further than the selection so is no good for what I need.

Does anyone have a one liner solution or can point me in the direction of a script that does this that I can edit to fit my needs?

Many Thanks in advance, Bren

Fiddle with the zoomPercentage.

  app.activeDocument.layoutWindows[0].zoomPercentage = app.activeDocument.layoutWindows[0].zoomPercentage;

Thanks for the reply,

Unfortunately this does a fixed percentage zoom and doesn't take into account the size of my current selection which changes every time the script is run.

Well, I could imagine something working better than this, but didn't find yet…

Hiya,

It seems to zoom right in on the back-most object and de-select all the others but it gives me something to work from, I will have a go at altering this and come back with any results.

Thank you

Hi Michel,

I have figured out how to do this for my needs but unfortunately I was not able to come up with a script that would work for the masses.

I work on catalogues that the finished page is 269mm high, I expand the page to 1269mm, add a second page then add product and wanted to zoom to fit the product.

Below is how I have achieved this but it's not a script that will be that useful to most, unfortunetely I couldn't get anything from wintern's link to work as I required.

    // Zoom view to fit all on spread

        pageHeight = app.activeDocument.documentPreferences.properties.pageHeight // Find current page height and set up variable

        app.menuActions.itemByName("$ID/Group").invoke(); // Run Menu Command "Group"

        var selecCopy = app.selection[0].geometricBounds; // Read group size

              selecWidth = selecCopy[3] - selecCopy[1];

              selecHeight = selecCopy[2] - selecCopy[0];

        app.activeDocument.align(app.activeDocument.selection, AlignOptions.VERTICAL_CENTERS, AlignDistributeBounds.PAGE_BOUNDS); // Centre selection vertically so zoom works

        if (selecHeight <= 269) {selecHeight = 269} // If selection height is smaller than the finished page size, make the page the zoom size 269mm

        app.activeDocument.documentPreferences.properties = {pageHeight: selecHeight} // Alter page height

        app.layoutWindows[0].zoom(ZoomOptions.FIT_SPREAD) // Zoom: Fit to spread

        app.menuActions.itemByName("$ID/Ungroup").invoke(); // Run Menu Command

        if (selecHeight != 269) {app.activeDocument.documentPreferences.properties = {pageHeight: pageHeight}} // Unless page is 269mm high, revert to previous height

Hi,

If well understood, you just want to max-zoom on the items selection! …

So … several or just one item!

Hi Michel,

since you did not post any code, I can only assume that you somehow are working with property bounds of layoutWindow.

But this will not give you the right numbers in a case like that:

layoutWindow bounds are discussed e.g. here:

window.bounds gives weird results

Oh, and this one could be interesting as well:

Moving and Sizing the activeDocument Window?

So I fear that layoutWindow.zoom( ZoomOptions.FIT_PAGE ) is the only choice to get a good-enough value for layoutWindow.zoomPercentage. Of course that would leave a small gap between the layoutWindow's inner border and the selected objects. Just like the little gap you see between the page edges and the layoutWindow in the screenshot above.

I'm testing the following algorithm and it seems to work good-enough for me:

1. Calculate the visible width and height of your selected object(s)

2. Add a page to the document temporarily, set all margins of that page to zero.

3. Change the size of that page to width and height of your selection

4. Make the spread of the added and resized page the active one

5. Do doc.layoutWindows[0].zoom( ZoomOptions.FIT_PAGE )

6. Read out value of doc.layoutWindows[0].zoomPercentage

7. Make the spread of your selection the active spread

In case you lost your selection in the process of 1 to 7:

8. Do doc.layoutWindows[0].zoom( ZoomOptions.FIT_SPREAD )

9. Select your objects

10. Do doc.layoutWindows[0].zoomPercentage = value where value is the one from step 6.

11. Remove the added page from step 2 and perhaps a group from step 1.

If you managed to fit the selection without using bounds of layoutWindow then I suggest you post some code.

Regards,
Uwe

A note on the value of property zoomPercentage:

It seems that there is a restriction to the maximum value you can do by scripting that differs from the maximum value you can do with the UI. For my screen on my machine this maximum value is 3000 %. With the UI one could zoom in to 4000 %. Value 3000 correspond to the value I see if I create a document with a tiny page size like 1 mm x 1 mm and do keyboard shortcut Ctrl 0 ( Windows ) or Cmd 0 ( Mac ) to fit the page to the layout window.

And of course there is a minimum value for page size that is 0.353 mm x 0.353 mm and a maximum value of 5486.4 mm x 5486.4 mm.

Hi Michel,

Looks like that's what I was originally looking for, mine works fine for me but it would be handy if you would post the code for yours, may help others looking for the same thing.

Thanks, Bren
