Ease of use
The library has been designed to be extremely simple
in use. Our motto is: make difficult things simple instead
of simple things difficult.
Not limited to the local PC
The unique FreeImageIO structure makes it possible
to load your images from virtually anywhere. Possibilities
include standalone files, memory, cabinet files and
the Internet, all this without recompiling the library!
Plugin driven
The internal engine is made completely modular using
a clever plugin system. Easily write new plugins and
store them in DLL files or embed the plugins directly
into your application!
Color conversion
FreeImage provides many functions to convert a bitmap
from one bitdepth to another. The library supports 1-,
4-, 8-, 16, 24- and 32-bit images, as well as integer,
real and complex images.
Support for High Dynamic Range images
FreeImage supports RGB float images as well a 48-bit
HDR images and provides tone mapping operators to convert
these images to 24-bit LDR images.
Directly access bitmap bits and palette
Functions are provided which allow you to directly
access the bitmap palette (if available) and bitmap
bits.
Metadata support
Parse common metadata models attached to your bitmap.
FreeImage supports Comments, Exif (including GPS and
maker notes), IPTC, Adobe XMP and GeoTIFF metadata models.
Written in portable C++, should compile on all 32-bit
Windows, Linux and Mac OSX systems.
Full source code is provided.
Open Source Dual-License
You can choose the license that has the most advantages
for you: Use the liberal FreeImage Public License to
use FreeImage commercially or the GNU General Public
License to use FreeImage into your open source project.
Easily integrates into DirectX and OpenGL.
Only a minimum of programming is necessary to store
a FreeImage bitmap into a DirectDraw surface or to use
FreeImage to load your Direct3D/OpenGL textures.
Provides basic image manipulation routines
such as rotation, resizing, flipping or color
adjustments, as well as lossless JPEG transformations.
Provides test programs to "show-off"
the library, compilable and startable on Windows 95,
98, NT, 2000 or on Linux.
