News & Announcements / Code Syntax Highlighting
« on: 28 July 2011, 23:28:59 »
You can post source code with syntax highlighting using [code=lang]your code[/code] tags. For Delphi/Pascal use [code=delphi] or [code=pascal].

Result looks like this:
Code: Pascal
  1. procedure AddOne(var I: Integer);
  2. begin
  3.   I := I + 1;
  4. end;

News & Announcements / Next update info: 0.80
« on: 25 December 2009, 03:25:10 »
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 modifications, extensions, demos, etc. contributed
    by users (now with ExtraGIF, NIF loader, and HqResampler).
  • (*) Changed conditional compilation of ImagingComponents

Bugs And Other Insects / [Read First] Bug reporting guidelines
« on: 22 October 2008, 23:51:18 »
If you have a bug to report, please include this information in your post:
  • Version of Imaging library you are using
  • Compiler (Delphi 2007, FPC 2.4.2, etc.)
  • Operating system (Windows XP, Fedora 12, etc.)
It would also be helpful if you could test the bug in more than one compiler and/or operating system.

If you have problem with some specific image, upload it here.
32/64bit note: On platforms that can be 32bit as well as 64bit please report OS as well as your executable "bitness", e.g. Windows 7 (x64) + FPC 2.5.1 (64bit exe).



You can post source code with syntax highlighting using [code=lang]your code[/code] tags. For Delphi/Pascal use [code=delphi] or [code=pascal].
Result looks like this:
Code: Pascal
  1. procedure AddOne(var I: Integer);
  2. begin
  3.   I := I + 1;
  4. end;

News & Announcements / Imaging 0.26.0 Released!
« on: 28 August 2008, 11:40:59 »
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, ...).

News & Announcements / Next update info: 0.24.4 >> 0.26.0
« on: 25 January 2008, 01:51:40 »
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.

News & Announcements / Next Release Info: 0.24.2 (Nov/Dec 2007)
« on: 17 September 2007, 14:01:38 »
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.
