Your looking to use the mogrify component of ImageMagick $ mogrify -contrast (to enhance) $ mogrify +contrast (to reduce) You could use one of PHP's program execution functions to call mogrify as above. exec('mogrify -contrast' . $image .

Hi, I have a requirment to dynamically brighten, darken or add/remove contrast from a thumbnail image, since I cannot do this in GD I was thinking of doing this in ImageMagik, but searching google I cannot find many tutorials and even visiting the image magik site i only see that it can be used with php but no examples were given. Any idea of any classes that use imagemagik to do the above or you have any code taht does the above or can recommend some tutorials that do that above, please reply.

It's not unbelievable. JPEGs can be highly compressed, and expand to a lot of image data. Depending on the type of image, the GIF format might not be able to handle it very well. I'm guessing the images are pretty large physically ( 100 or hundreds of pixels in each dimension), correct? miguel -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I have used PHP to generate a series of JPEG files, which after doing: convert -delay 0 *.jpg animated.gif make a rather nifty animated GIF file. Just one tiny problem... How the heck do 8 files, ~24 K each, turn into 3 *MEGS* worth of animation?... I mean, I've read the GIF spec, and there just ain't that much there... I've tried all the reasonable flags to convert I can find in "man" and Googled, but got nothing so far... Please Cc: me... And, I'm not being stupid, right?... There's no PHP image_frame() right?...
