Examples » Send cropped image coordinates to the server

Many people ask me for how they can send coordinates of cropped image to the server with help of MarqueeTool. If you one of them or just want to see one of use of MarqueeTool, please see example below. All you need is only select (crop) part of image below and click "sumbit" button.
Any comments from you will be very appreciated. Feel free to leave few lines of your thoughts or report bugs. If you want to contact me by email please use contacts page. For detailed information see documentation page.

An Xellent Tool! Gr8 Job!

But
var coords = MarqueeTool.getCoords();

Is causing page error for me, What would be the problem?
Plz Help!

2. Sergey Koksharov (Aug, 09 2007 at 03:26 AM)


Hi Jijo!
What is the scope of your variable MarqueeTool? It must be global if you want it to see/use in function
var MarqueeTool; // use this before all functions

Can you email me with sample of your code or link to your page?

Thanks for your interest to Marquee Tool!

Regards, Sergey

Hey, I am trying to get this to work on my site, but I just can't figure out how you got the thing to work with the code posted above. What is the point of the php code above? And why does the form post to crop.jpg, what is crop.jpg? I can't even get the marque tool to appear on the image. I'm confused, lol.

Regards,
Jordan

4. Sergey Koksharov (Sep, 16 2007 at 04:54 AM)


Hello Jordan!

Make sure what you did all right.
- marker.css, prototype.js, and rectmarquee.js must be included in html and javascript must be enabled!
- crop.jpg its a crop.php file what in .htaccess rewrited to crop.jpg (rtfm for mod_rewrite);
- code for crop.php showed above.

If you have any questions or want to show me link to your working/not working page - feel free to contact me.

Regards, Sergey

7. Daniel (Jan, 28 2008 at 05:52 AM)


Hello, you can not imagine what I wanted this!
But I can not select and crop the image.
You could send me email around the zip code?
Thanks!

This is a terrific tool! Is there a way to constrain the cropping to a specified proportion (e.g. 4/3 width to height aspect ratio)?

9. Bryan Copeland (Feb, 15 2008 at 09:18 PM)


Amazing tool, thank you very much for being on "the good side" of free software.

Your work, among some other's who have helped me, have inspired me to keep everything I do as free, open and transparent as possible.

To create a preview you have to download 2 files : js/previewtt.js and js/src/scriptaculous.js (check source of this page) and paste this code:




This tutorial isn't good enough to create a preview.

But still, it's fantastic tool :)

11. Denis (Jul, 11 2008 at 12:25 PM)


Hello,
It is very good tool, but I couldn't run it in my browser, because I don't know from where to take marker.css, prototype.js, and rectmarquee.js.
Could you help me?
Regards,
Elle

Good night

I found very good the system that you developed, I would like to use.

I did everything, most of a mistake in the end, something with the function header ( "Content-Type: image / jpg"), and with readfile ($ image);

It seems that it is wrong the way for the folders,

If you can help me.

Sorry for my bad English

Thank you
