I intend to build square thumbnails by cutting off parts of the image (given the original format is not square). Currently I am using GD for image manipulation.
Let me give you an example:
User image upload is 600x400px. I resize it to 60x40 using imagecopyresampled.
My question is: How can I cut off 10px from the left and 10px from the right, resulting in a nice 40x40px thumbnail?
Thank you very much for your help,
I would look at Imagecrop
You may have to do some calculations to pass the positions to the crop function.
FYI: I decided to give the ImageWorkshop Class a try (found on http://phpimageworkshop.com/).
