All of these examples use the PHP simple image manipulation class that I created.
Every now and then I write a batch image converter snippet that others might find useful. I figure I’ll post them here for my benefit and yours. These snippets will also serve as a way to better understand the class. As I come up with these in life, I’ll update this post.
All of these examples assume that you’ve already included the class in your file.
UPDATE: I’ve added support for PNG alpha transparency which makes this class significantly more useful. Changelog in the class code below.
I keep misplacing this class so I figured I’d post it here so that I know where it is.
I wrote/assembled this class because I wasn’t happy with any of the image manipulation libraries out there. They are either way too complex with a steep learning curve or didn’t work all that great. (I didn’t see any reason to load up a class with 3,000 lines of code just to resize or rotate an image.)
So here it is, a simple class that allows you to open an image, perform common operations, and save. There are no bells and whistles or anything exciting here. Just a collection of commonly used image manipulation functions: Rotate, Flip, Resize, Thumbnail (square and regular), and Crop.
A lot of the class code is original but some of it has been gathered over my life as a programmer from long lost sources. If you recognize your work, leave a comment and I’d be happy to cite you!
