Image Cropping

Which function?

[inveni0]

I'm curious if anyone knows which function you use in PHP to crop an image. Can you use imagecopy?

[vincevincevince]

Use a combination of imagecreate an imagecopyresampled

Can you help with a bit more detail?

EDIT:

Actually, it appears that ImageCopyResampled does what I need. I'll start experiementing! Thanks.

Read the user notes below those functions at php.net - they have some good examples :)

I should have said imagecreatetruecolor not imagecreate - you should get better results.

I have already managed to get it working. I'm using it in conjunction with Flash to create a smooth, easy to use image size/cropping tool. It works really, really well.

Thanks for your help!

I can see how that would work well with Flash - although - Flash can do that kind of resizing and cropping itself - which will be much faster user experience.

In the past I've made javascript based systems for selecting areas to crop or enlarge on an image, with PHP image functions as the back end.

Well, there's a significant amount of database integration I have to do with this. Instead of trying to import all of the variables into Flash, I simply use flash as a visual representation of what the user intends to do. Once they've made their decision, they submit just two or three variables to php and the php script handles all the database functions. I thought it would be less buggy to not integrate php into flash. (not to mention easier on my programming brain...the two languages are just similar enough that I get confused, lol)

invenio,

We are trying to do a similiar application where we want to allow people to upload an image into a flash movie. Rotate it, zoom, crop, etc. and then when complete pass the variables back to php to then execute what they have designed.

I'd be interested in seeing what you were able to accomplish because we are unsure how to deal with the zoom variable and how to pass the variables that tell exactly where the user wants to crop.

How did you get around those variables?
