I am looking for a decent image cropping solution, ideally a script that would do the following :
Allow to upload an image (ideally via ajax), crop the image using some jQuery like cropping tool and then save the 'new' cropped image while retaining the image untouched.
Is there anything people could recommend?
Use Pixastic for client-side image processing.
Edit
It sounds like you might be looking for an image crop GUI for users, rather than a way to programmatically crop images (as I read your question originally). In that case, there are a variety of jQuery plugins that provide this; jrac seems to be a reasonably up-to-date one.
you can check here it is good tool

Hi I've been working with the iTunes API and what I've done is saved the data that's returned from the search into the database. I'm saving the iTunes image URL to my database and I'm wondering what would be the best method to crop the image from the URL with PHP, or is it better to crop the image with jQuery before I display the images on the site? Thanks in advance for you advice!
You're going to want to crop images server-side, probably. Cropping client side means the client is going to have to load the whole image, and that will slow down page loads (potentially a lot, depending on how big the images are).
Cropping server-side means that you'll have to save the cropped images to your server and serve them from there. This is more of a pain than just doing the cropping client-side, but it will probably be better for your users in the end.
Since you're using PHP, you want ImageMagick.

It is best to crop and store the cropped versions on the server, that way the images load faster and you save a lot of bandwidth.
I'd like to know which up-and-crop tools you suggest to me. I tried couple of scripts like JCrop but I always get stack with some type of format like bmp. I either can't upload or I can upload but can't crop. If you use (or know) one that works well with different formats, then please just give me its name and I'll be strongly appreciated!
Well, i dont know much about JCrop but you can build it up with several tools.
I think image processing kind of works should be done on server side.
There is a good OOP Library called Imagine. It's mostly based on Python's Imaging Library which is awesome and has decent documentation. And this is its crop functions documentation.
On client side you can use some kind of image area selection tool to let the user determine desired area to crop. imgAreaSelect is good to go. Then you can send crop area to php by JQuery's post function or any other way.
It's amassing that in all this time this haven't got any other answers, I hope this helps.
Like stated in the other answer you should combine a few tools to solve each part of the problem.
To let the user select the cropping area:
If you don't like jCrop you can try Guillotine. It's very lightweight, easy to set up and allows to crop, zoom and rotate images. It has touch support and it's responsive (fluid).
Keep in mind that you can't display image types that the browser doesn't support, but you can convert them in step 3.
To upload the images:
For most cases, once you have the cropping area, with a simple file input will suffice.
Now, if you want to upload files asynchronously check out
this
for a quick and easy set up or this
for a more complex solution.
To actually crop and process the image:
Once uploaded you can crop, convert and process the images on the server, ImageMagick is a great tool for this. It's Open Source and many languages have wrappers for it.
You've tagged the question with PHP so here is a PHP wrapper for ImageMagick.
I am working on a site at the moment, that requires the admins of the site to be able to upload pretty much any size of image, I then need to find a way to get the image down to the size required for the front end of the end the site, all this needs to be done without know what size of image the user is uploading, but the image always needs to scale to 209x293 without looking awful.
Is this even possible?
You should argue with your client, to forget that rule(accept ANY image), and accept rather, only images in that proportion, or better, you can use a tool to crop the image, forcing the user to crop an image in your needed resolution.
Jcrop is a library in Jquery which can help you a lot if you want to create that cropping feature.
Don't know your precise requirements, but since you tagged it with CodeIgniter, you can check out the Image Manipulation Class which has everything you need to do the job.
Not knowing the size of images before uploading is, you know, quite a common problem...Just be careful of the MAX SIZE, which is set in your php.ini.
You might find useful also the page on file uploading right in php's manual.
I'm working on a web application that need to allow the user to drag and drop as well as rotate an image.
Drag and drop is solved with the jQuery UI Draggable.
But how am I suppose to rotate an image on the page? My images are mostly one colored rectangles. I used divs to draw them on the page but how to rotate them?
It is okay if they only rotate 22, 5-45-67, 5-90 degrees
So I think of 3 solutions
Using Canvas
Problem: IE support
Using divs
Problem: it also needs canvas to rotate
PHP GD
This solution is the only hope that left.
How it might work: The application will prerender (22,5*x) rotated versions of original image. So they will be ready whenever user wants to rotate an image.
Please help. Any suggestions appreciated
One possible solution is to use a JavaScript graphic vector library that can use automatically an alternative to canvas when used on IE.
Raphael is a really good one, give it a try:
http://raphaeljs.com/
You can find more informations about rotation with raphael here:
How do I rotate a div with Raphael.js?
take a look:
http://www.dyn-web.com/code/rotate_images/
Rotate image clockwise or anticlockwise inside a div using javascript
The server side method sounds a bit wasteful (all versions of the image need to be downloaded), dare I say you should try using Flash for a cross-browser and client side solution.
You cannot manipulate image directly with Javascript other than resizing them (and this is technivally done with CSS, not Javascript...). The best solution would be to use Raphaël; it will allow you to ratate, but also drag and drop, and it is also built using JQuery.
Of course you could alternately use different image states and use them as "sprites" for your rotated rectangles, however you will not play extensibility there. (GD is a bad design, don't use that.)
I am working on a website in which the client wishes to have users upload background images to a printable design, crop to size, add text. Do this to multiple pages then generate a pdf of the 'book'
I am running into the following issues/questions and just need to see where I can start
Are there any PHP developer packages that can do something similar. I have seen jquery crop tools but something also for adding text to an image?
How would I keep the resolution up? If the final cropped with text image needs to be 150dpi, when cropping I am guessing I would have them working on a 72dpi image, then somehow apply the crop and changes to the large image?
If the resolution issue wasn't a big deal I would go about it this way:
Simple image upload
Use jquery to crop photo to correct dimensions
Mess around with gdlibrary and imagettftext() to get the text onto an image (page)
Use something like FPDF to create a pdf from each 'page'
Is this the right way to go about it and any thoughts on the resolution issue. Thank you for any help!
Your primary tool should be ImageMagick. ImageMagick can do the cropping, resizing, scaling, overlay text or graphics, combining images, and apply special effects. A big advantage of using a separate tool instead of PHP's image manipulation tools is that you can do the same transforms in batch through other mechanisms, or even hand the work over to another server to keep the website more responsive. And if you do want to integrate it tightly into the website, you can use the MagickWand For PHP interface.
Cropping does not change DPI, only the dimensions of the image. Scaling, on the other hand, changed both.
You should take a look at Gallery, a GPLed program with some of the functionality you're looking for, and written in PHP.
domPDF is a good tool for converting HTML to a PDF. this way you can use the image they upload as a background image, then put the text over it in any standard HTML tag.
As far as the resolution/dpi issue goes, I'm not sure if there is much you can do outside of changing the size of the image. I would recommend looking into This PHP Library, which has a lot of good tools for manipulating images.
I think with a combination of these tools, you'll be able to create HTML that can make a PDF that's fit to print, and use that.
