Hey,
Aggggggggggggggges ago I mentioned that I was writing a 'photoshop clone' in PHP for a bit of a laugh. Well, the first version is online for people to have a bit of a play with..
http://www.ooer.com/phphoto
Theres a few bits and bobs that aren't working yet and throw errors out.. shocking stuff.. but theres a lot that does work:
Photo uploading
Guides
Colour pick
-- from image
-- from colour space
-- from swatch
Resizing
Cropping
Rotate
Offsetting
Flip (horizontal and vertical)
Text
Line
Watermark
Vignette
RGB Channel extraction
HSV Channel extraction
Filters
-- Emboss
-- Gausian Blur
-- Smooth
-- Sharpen
-- Edge Find
-- Drop Shadow
-- Jitter
-- Glass Tile
-- Mirror
-- Ripple
-- Invert
-- Scanline
Image details
Image histogram
Although it still needs a lot more work if anyone has any comments I'd love to hear them (I expect there'll be a few along the line of "Why?!").
Oh, and the new version of my website is online too: http://www.ooer.com .. theres a bunch of PHP related articles there, but most of them are rather basic stuff and probably not of much interest to the folk here.
