Imlib2 1.2.0

Imlib 2 is the successor to Imlib. It is NOT a newer version -- it is a completely new library. Imlib 2 can be installed alongside Imlib 1.x without any problems since they are effectively different libraries which have very similar functionality.
Main features:
- Load image files from disk in one of many formats
- Save images to disk in one of many formats
- Render image data onto other images
- Render images to an X-Windows drawable
- Produce pixmaps and pixmap masks of Images
- Apply filters to images
- Rotate images
- Accept RGBA Data for images
- Scale images
- Alpha blend Images on other images or drawables
- Apply color correction and modification tables and factors to images
- Render images onto images with color correction and modification tables
- Render truetype anti-aliased text
- Render truetype anti-aliased text at any angle
- Render anti-aliased lines
- Render rectangles
- Render linear multi-colored gradients
- Cache data intelligently for maximum performance
- Allocate colors automatically
- Allow full control over caching and color allocation
- Provide highly optimized MMX assembly for core routines
- Provide plug-in filter interface
- Provide on-the-fly runtime plug-in image loading and saving interface
- Fastest image compositing, rendering and manipulation library for X
If what you want isnt in the list above somewhere then likely Imlib 2 does not do it. If it does it it likely does it faster than any other library you can find (this includes gdk-pixbuf, gdkrgb, etc.) primarily because of highly optimized code and a smart subsystem that does the dirty work for you and picks up the pieces for you so you can be lazy and let all the optimizations for you.
Imlib 2 can run without a display, so it can be easily used for background image processing for web sites or servers - it only requires the X libraries to be installed - that is all - it does not require an XServer to run unless you wish to display images.
