Re: Script to center-crop images to a fixed ratio

This may be a super dumb question, but the script presented by GCT13, how do I take that and use that in Photoshop? I have only worked with actions in photoshop, never scripts? What are the steps to taking what GCT13 posted and turn it into something I can use in PS-CS3?

Re: Script to center-crop images to a fixed ratio

Hello Mr. Jones! It's actually a good question, because it's the same one I was asking of these guys and didn't really get an answer, and in the end I had to figure it out myself.. You would open a fresh new txt file, paste in the provided code, change the variables for the crop to your suiting and save it as a 'whatever.jsx' file (change file type to 'all files') in your work folder or wherever you can remember it.. then start a new action record in photoshop, doing everything I described in my last post. Also I discovered that for images less than the desired resolution (such as 1600x1200 for example, still good enough imho) you should resize the image to 1680 width (if that happens to be your desired resolution) relative to whatever aspect ratio your source is *before* you run the script to crop - if you don't do this it seems that images that start at a lower resolution or an odd res like 1280x960 end up with white bars on either side after you run an image batch using the action you've recorded. Hope that helps..

Re: Script to center-crop images to a fixed ratio

GCT13, how would you change that script to make the document 2000x2000 as well as being able to center the image and have it line up at a specific X coordinate?

Re: Script to center-crop images to a fixed ratio

This script can make any aspect ratio selection you want can be centered rectangle or oval be feather etc. It is a Photoshop Plug-in and will be listed in the Photoshop menu File>Automate>Aspect Ratio Selection. Can be used while recording an action and the values used in the scripts dialog will be recorded and used when the action is played.

AspectRatioSelection.jsx

Re: Script to center-crop images to a fixed ratio

Thanks jjmacks for the Script. That is very good.
An improvement would be still, if it is possible presets to save and load function!

Thanks Wolfgang

Re: Script to center-crop images to a fixed ratio

Wolfgang
As a Photoshop script plug-in you can record its use in and action. The setting you set in the Plug-ins dialog during recording the action is recorded in the action and will be used when you play the action. You can of course turn the dialog on in the action and make that step interactive. You can download this script and many more here

Re: Script to center-crop images to a fixed ratio

Hi, I'm very new on photoshop scripts and I need help I tried your scripts but doesn't work:
I have folder with 120 images (png)that they where exported from 3ds max. Every picture is the same object that moves a little bit more making a circle of 120 pictures. All the background is transparent and the object is black let's say the canvas is 1098x824 and the object 152x162 (the size changes because some times I see it closer so is bigger than when is far looks smaller). So in every picture the x position and y position are different. I have the width and height for the crop of every picture. What i need is a script that:
Open each file "MouseOver_???.png"
Put the crop tool on the x and y of the object.
Take the size Iwidht and height) from an array that I have
Crop the image
and Save it on the same name.
Open the next image... till 120
Please help me, I don't know how to do it and I just so frustrated!!!
Thanks in advance

Hello and welcome to RP.

Your situation is way over my head, but I can point you to a site where there are some very knowledgable scripting folks:

www.ps-scripts.com

If no one here at RP can help or you need a second opinion, I'd sure give PS-Scripts forums a look.

Good luck with your project.

Re: Script to center-crop images to a fixed ratio

Thank you!
I tried in ps-script but I didn't get a "confirmation" as a member so I can't post my question ...
I don't get the answer from any posts there...

It's possible PS-Scripts registration requires "human" approval unlike many forums that auto-approve. It is "middle of the night"/very early Sunday in the U.S. at the moment (I don't know your world location) and it is likely no one who is a PS-Scripts admin is logged in to approve your request. I would expect you will get a 'confirmation' in the next 24-36 hr.

Your question is fairly specific, so it does not surprise me that you did not find an a answer to your question. I've interacted with some of the script experts there in the past and if anyone can give you good advice on a solution or workaround it will be one of those guys.
