Smart image resizer is a PHP script which makes it very easy to resize & crop images. And, this is done without touching the original image.

The width & height of the image to be resized is mentioned in the img tag like:

<img src="/image.php/coffee.jpg?width=200&height=200ℑ=//uploads/coffee.jpg" alt="Coffee" />

and image is resized via the GD library.

Newly created image is stored in a cache directory & won’t be re-created until new dimensions are mentioned to improve the system performance.

Cropping an image also warks the same way. Simply mention the crop ratio & that’s all.

Smart Image Resizer supports JPG, GIF & PNG images and requires PHP 5.1.0+ to run.

FLIR (Facelift Image Replacement) is an image replacement script that enables you to use any font in your websites.

It is similar to sIFR but uses JavaScript + PHP rather than Flash.

Fonts to be used are pre-uploaded and a PHP script creates the image using these fonts. Later on the image is inserted via JavaScript.

PHP GD library can not render some fonts properly. For this reason FancyFonts plugin (optional & requires ImageMagick) is also integrated to FLIR and it can handle almost any font.

WideImage is an object-oriented PHP image library.

It is written in PHP 5 and requires only GD2 library for manipulating images.

The library is very suitable for new generation web applications (for easier mashups) as it supports loading images from any URL besides loading them from a file, string or a valid image source.
 

Some features of WideImage:

• Transformations: crop, resize, rotate, flip, mirror
• Conversions: graysclae, negative, truecolor, palette
• Colors/channels: merge, mask, filter, get channels, correct gamma…

pChart is an open source PHP chart library for creating aliased charts.

This chart classes run on any webserver that has PHP & GD library support.

Chart types currently support by this PHP charts solution are:

• Line chart
• Cubic curve chart
• Plot chart
• Bar chart
• Filled line chart
• Filled cubic curve chart
• Pie chart
• Radars chart
• Limits chart

For faster display of charts, pChart has a caching class named pCache which serves a chart from cache if it was rendered before with the same data.

This project is still in development (for ex: pie charts are in beta) but updated frequently and, even now, looks very functional.

PHP classes are well documented and they can be tested in a live test area.

Phototype is a client/server-side image manipulation library, based on Prototype and supports all kinds of image manipulations.

How it works?

Clientside JavaScript codes sends the commands to the serverside PHP - GD library image renderer and displays the rendered image.

Using Phototype, you are able to rotate, resize, flip and do some other cool effects to images.
