Theres a way to move the blur radious? (more blur or less blur)?

What’s the direction I need to take to make the image in question less blurry?

I think you should absolutely leave it there, it’s a great example of ImageConvolution. Keep up the great work!

Thanks for the suggestion – noted.

But I think I’ll leave the code as it is at the moment, just to introduce people to the ImageConvolution function if nothing else.

Glad to hear you enjoyed it :0)

Hey,

This is great stuff, I am a big fan of working with images and php, it’s pretty neat and creative how you pulled off the blur effect in php4 by offsetting the x/y axis. Nice work.

One quick note, I think you could save some time and lines of code with php 5 blur by using the ‘imagefilter’ function and calling ‘IMG_FILTER_GAUSSIAN_BLUR’

imagefilter($src_img, IMG_FILTER_GAUSSIAN_BLUR);

I do think you get more precision and options using the convolution technique though. Again, wonderful article, you’ve got a new subscriber :)
