Latest development version:

• Git repository: https://github.com/galfar/imaginglib.git
• Zip snapshot: https://github.com/galfar/imaginglib/archive/master.zip

Full releases (demo binaries, help, ...) - currently VERY outdated:

begin
  I := I + 1;
end;

Imaging's source code repository at SourceForge has been migrated from Subversion to Mercurial.
Subversion repository will still be updated for some time (probably till 0.80 release).

To access the new repository use this address:
http://imaginglib.hg.sourceforge.net:8000/hgroot/imaginglib/imaginglib

Link to Imaging's Mercurial overview page at SF.net

Planned features for next release:

   
• Metadata - simple way to load and save information about images other than just width-height-format. Currently reads/writes print resolution of JPEG, PNG, and TIFF images, frame delays of APNG/GIF animations. Raw XMP/EXIF/IPTC metadata support for some file formats.

   
• JPEG 2000 support improvements - from new version of JPEG 2000 for Pascal.

   
• Maybe some file mapping support for very large images (nothing in core though, just some hacky extension for now).

   
• Progress callback in few places.

   
• Direct3D 11 texture support

   
• Graphics32 interfacing unit

   
• Some support for binary (1bit) images. Support in file formats: PNG, TIFF, BMP.

   
• Image error metrics (psnr, rmse, ...)

   
• Default clear color (for new images, rotations, etc.)

   
• RAW (WxHxBpp) image bits loader/saver

             
• Delphi XE2 support for new targets/frameworks: Win64, Mac OS X, FireMonkey bitmap conversions

             
• Delphi XE3, Lazarus 1.0, FPC 2.6 support

             
• RGBE/HDR file format

   
• ..

Green items are done already.

I'm currently using Imaging in one bigger project and I need it to do some things it wasn't originally designed for (which was texture loading/saving for games) - implementation probably won't be very nice (metadata, progress, file mapping, 1bit stuff).

Imaging library 0.26.4 is finally here!
Here's a detailed change list:

• (+) APNG file format (Animated PNG) loading, animating, and saving added to existing PNG support.
  
  
• (+) Arbitrary angle image rotation.
  
  
• (+) Mac OS X (Intel) compatibility (garbled LCL bitmaps in Carbon, JPEG 2000 support, ...).
  
  
• (+) XPM file format saving added, JPEG 2000 file format loading improved. 
  
  
• (+/F) New canvas methods: premultiply and unpremultiply alpha. New methods for TFastARGB32Canvas: InvertColors, DrawAlpha/StretchDrawAlpha. Fixed DrawAlpha/StretchDrawAlpha destination alpha calculation.
  
  
• (+) Three new extensions in Extras/Extensions directory: ImagingJpegIJL.pas uses Intel Jpeg Library to load/save Jpegs (DLL needed), ImagingSquishLib.pas uses Squish DXTC library with Imaging (DLL needed), ElderImagerySky.pas loads SKY images from Daggerfall.
  
  
• (+) Conversions between RGB and YCoCg colorspaces.
  
  
• (F) Bug fixes: loading of some GIFs when using D2009+ failed, bugged XPM loading in Linux, indexed images resizing leak, PNM saving using D2009+, DXT3 alpha encoding, RGB>>CMYK conversion, garbled images in Lazarus GTK IDE.
  
  
• (*) Delphi 2010 and Lazarus 0.9.28 compatibility fixes.

New Imaging was finally released!
Detailed change list:

• (+) Canvas class was extended with many new methods and effects.
  They include image drawing with blending (custom blending factors),
  filtered image stretching, nonlinear filters (min, max, median),
  point transforms (contrast, brightness, gamma, threshold), and blended
  rectangle filling.


• (+)New data formats using 3Dc compression added: ifATI1N
  and ifATI2N.DDS file format updated to be able to load and save
  images in this format. OpenGL and Direct3D extensions were updated
  to allow creating textures in these formats.


• (+) New unit ImagingBinary.pas added with morphologic
  operations on binary images.


• (+) XPM file format loader added.


• (E) LCL Imager and Image Browser demos were extended
  with new functionality provided by canvas class (blending, filters,
  morphology, etc.).


• (*) Updated OpenJpeg library (JPEG 2000) to version with
  my CDEF patch that saves JP2 files with alpha properly.


• (*)Changed some file format loaders/savers to be more thread safe
  so more images can be loaded concurrently..


• (F) Many bugs in library fixed (GIF, BMP, and PNM loaders,
  ConvertSpecial, linear filters, ...).

Next update of Imaging 0.2x branch will be 0.24.4 (April/May June/July 2008?).
Next update of Imaging 0.2x branch will be 0.26.0 (end of August 2008).

There will be new data formats: compressed 3Dc (ATI1N and ATI2N)
and support for them in D3D/OpenGL extensions.
XPM file format loader is long due and there will also be
other additions since I'll be using Imaging in my MSc thesis (terrain rendering stuff).
And the bug fixes of course. 

EDIT: I'll also modify OpenJPEG library to allow saving proper JPEG 2000 images with alpha channels and updated OpenJpeg to version 1.3.

Status Update 31.5.2008: I've just added 3Dc data formats to Imaging, various
bugs were fixed in image loaders, and some level of thread safety was ensured (image loaders).
Due to work on my thesis new Imaging release didn't make it in April/May so the new timeframe is
June/July. July is more probable since now I have to study for my final exam.

Status Update 8.7.2008: I've made some canvas extensions (point transforms, non-linear filters)
and I'm planning some more (drawing images with alpha blending). There will be quite a few new things
in new Imaging version so I decided to change its version number from 0.24.4 to 0.26. I hope to get it finished before the end of July.

New version of Imaging was released few hours ago.
As stated before it is patch and update release with no
important new features added.

News/changes in 0.24.2:
  - Updated OpenJPEG (JPEG 2000) library to latest revision and added JPEG 2000 support for 64bit Linux.
  - Fixed compatibility issues with new Lazarus 0.9.24 and added project files for RAD Studio 2007.
  - Updated LCL Imager demo and added new features to OpenGL texture builder.
  - Bug fixes in JPEG and GIF support.
  - Pascal translation of Hq resampler with Imaging demo added to Extras directory.

Head to Imaging Homepage for downloads and updated documentation.

Work on Imaging 0.3x branch is about to begin in few weeks.

What library features should I focus on first?
What should be extended or added? (compared to current version)
Please make a vote.

Note: SMF only allows registred users to vote in a poll.

Next Imaging version will be patch release
0.24.2 with no new functionality added.
You can expect bug fixes, library updates (OpenJPEG, LibTIFF),
and compatibility fixes for new RAD Studio, Free Pascal, and Lazarus (if needed).
Release date should be sometime in late October or early November.

EDIT:
0.24.2 is almost ready. I'm just waiting for new OpenJPEG (JPEG2000 support) release which should be significantly faster, everything else is done. OpenJPEG 1.3 should be released this week or the next one. Imaging 0.24.2 will be released few days after that.

Version 0.24.0 of Imaging has been released today!
As stated in the previous development progress topic main addition
are new file formats.

Main news/changes in 0.24.0:
  - New image file format support: GIF (native), TIFF (libtiff), PSD (native).
  - New image data format: BTC (block truncation coding).
  - File format compatibility fixes (for BMP, JPEG, and DDS)
    and platform/compiler support fixes (Win64, UNIX, FPC, ...).
  - Bug fixes and some enhancements (buffered file IO, ...).
  - More

Head to Imaging Homepage for downloads and updated documentation.

I'll be updating this post with information about (major) stuff I add/fix/change
in current working version (which is now 0.23). It is available
in Imaging's SubVersion repository at SourceForge
SourceForge.

EDIT: I will finally have some free time in June so I'll devote it to Imaging 0.24 release. No date yet, probably late June / early July.

EDIT2: Code for 0.24 will be finished this week, next week will be testing and documentation update.
So 0.24 release will be ready around 30/31 June weekend.


20. 3. 2007
Added loader/saver for Photoshop PSD image files to Extras.

14. 6. 2007
Added BTC image data format (block truncation coding).

18. 6. 2007
GIF file format loading support complete.

20. 6. 2007
GIF file format saving support complete.

21. 6. 2007
TIFF file format loading and saving (using libtiff - only for Delphi now).

I'll be definitively adding GIF support to library core (loading and saving, native Object Pascal) and TIFF (although this may come later). High level interface will be extended some more and there will also be more checks for parameters validity and asserts.

As stated in library docs I'm going to overhaul major parts of the library which should allow  things (among others that will make further Imaging development easier for me) like custom image data formats and progress callbacks. I will create branch in SVN for this new version in near future (versions 0.3x will be betas of new architecture, 0.40 will be final release).

EDIT: Photoshop's PSD format loader will be added to Extras package too.

Problems with compiling Imaging with Free Pascal (Win32) have been reported lately - fatal errors in JpegLib units. MODE DELPHI was set after uses clause in units that caused problems and FPC just ignored it, so compilation failed on some statements.

Problem was fixed - MODE is now set at the right place. Updated code is in SVN repository.

Version 0.22.0 of Imaging has been released!
As I posted before, main new addition is Extras package with
several new file formats and other stuff.
There are also changes in general file format support and other places. As always, all bugs that were found were fixed (and I hope not many new ones created).

Main news/changes in 0.22.0:
  - Extras package with support for PCX, JPEG 2000 (not native), and
    old Bethesda games images (IMG, CIF, texture.*, BSI).
  - Core library support for loading and saving Portable AnyMap formats:
    PBM, PGM, PPM, PAM, and PFM.
  - High level interface classes were extended and updated as well as VCL/CLX/LCL
    support, low level interface, and canvas classes.
  - Demos were extended, updated, and fixed.
  - More

There were probably problems with previous forum theme not showing some SMF extensions
(like captchas - but it did require input from them) sometimes - it worked for me but guessing from SMF error log not for everybody.
I have set the forum to default SMF theme (where everything is as it should be) for now.
