cs3 straighten and crop , is there a way like cs5?

Before Adobe added that feature, I always had to do the crop manually.  I agree, it's a nice feature in the newest Photoshop.

There's a possibility someone made a script for it I suppose, but I don't recall hearing of one.

Do you have a Photoshop CS5 license?  Did you know you're allowed to install it on two computers (e.g., your desktop and your laptop)?

That's what the crop and straighten script does...

You could try recording an action, where you select the surrounding area (with a stop in the action) and it would do select>inverse, and then edit>trim.

h, I see that Paul has provided a script that might fit your needs.

You would need to crop the image, in this case, but would miss the relevant parts. CS5's content aware fill would help.

You do use Photoshop in Italian?

Yes, in this case, trim is useless as it already fits the top and bottom and side of the image anyways.

I don't know about the script issue, I was raising it in case it might help Paul troubleshoot the script.

Just in case, How did you try to use the script?

What I meant by missing the relevant parts, is that the passage would be severely cropped to fit the edges, given the strong rotation.

That's an interesting thought.  I haven't actually tried running Photoshop CS5 on an older PC, but I never noticed that it seemed any more sluggish than its predecessors.  Did you actually try it, or are you just assuming it would be too slow?

I should think Photoshop CS5 would run just about the same as Photoshop CS3 if you disable OpenGL Drawing (assuming it can even try to enable itself on your laptop).

-Noel

Photoshop CS6 is not yet available.

It's possible, depending on your laptop, that OpenGL Drawing will be available and work well enough.  But if it doesn't the fallback is to manage the screen displays in the same manner as Photoshop CS3, using GDI functionality.

From what I gather you haven't had much luck so far in adapting a script to bring Photoshop CS5 functionality into CS3.  That's the reason I suggested considering installing the software you already have a license for.

-Noel

The script works here on cs3.

Maybe you missed part of the script when you copied it.

I saved it as AutoCrop.jsx.

I don't have CS3 here. But is your version up to date? is the scripting support correctly installed?

Both versions work good on most images, but i couldn't really get a good test on your screenshot.

You can try the scripts on this image as all the settings in the v2 work on this image as well as v1. (this is the only image i had that came close to yours in terms of colors)

https://acrobat.com/#d=bLrN2-PPlmGJacISa1pu9A

Added: I should also say that the v2 script doesn't work very well in cs5, but the v1 seems to work fine.

Yes, in cs3 both scripts work on that photo, but the difference could be either because your language version is different or your on a mac.

I'm using windows english and i don't have cs3 on a mac to test. Perhaps someone else that is using cs3 on a mac will verify whether the script v2 works for them.

And yes the v2 script doesn't seem to work very well on windows cs5. (i get the same results in cs5 as you do in cs3 with the v2 script, but you don't need it in cs5)

If the v1 script works for you, then i would just use that. And if you make an action for rotate and crop, then you wouldn't have to deal with the dialog, which is a plus.

With the v2 script there is an omission in the program, it expects you to have the ruler units set to Pixels, if you haven't the script does not work as it should.

you could add this line at the begining of the script...

app.preferences.rulerUnits = Units.PIXELS;

Thanks for the info and that would make sense why it might not be working for mantralightroom and why it didn't work in cs5 (i had the ruler units set to inches).

I really need to learn more about scripting.

I made the change to the scriptv2 as Paul suggested, so hopefully it should work for you.

This script is product of Paul Jaruszewski and Roger Cavanagh

https://acrobat.com/#d=B3TH8GEmaGU7oZKYBQh3rA

This sets the rulerunits to Pixels then when finished resets them back to what they were....
