Vampyre Imaging Library 0.22.0 Released

[Galfar]

New version of Imaging was released few days ago. Support for quite a few new image
file formats was added and many bugs were fixed.

Current Imaging info and features:
Imaging is native Object Pascal cross platform image loading, saving and
manipulation library. Main development language is Object Pascal (Delphi, Kylix and Free Pascal compilers are supported) and there are interfaces to the library (compiled into dll/so) for other languages like C/C++ and Delphi.NET. Currently supported operating systems are Windows, Linux, FreeBSD (and some other Unixes), DOS (and .NET using unmanaged DLL). Supported CPU architectures are x86 and AMD64.
Currently supported image file formats are: (loading and saving) PNG, JPEG, DDS, TGA, MNG, JNG, BMP, JPEG2000, PGM, PPM, PAM, PFM (loading only) PCX, and PBM.
Many internal image data formats are supported: 8/16/24/32/48/64 bit RGB and ARGB formats, indexed formats, grayscale formats, half/single precision floating point formats, and compressed formats DXT1, DXT3, and DXT5.
Additionally there are extensions for creating SDL surfaces, OpenGL and D3D9 textures, VCL/LCL TGraphic descendants, canvas class, and more.

i can't get it to work in freepascal under win32, it errors with this:

any ideas what i'm doing wrong?

edit: seems like {$mode delphi} helps ;)

[Galfar]

That is strange. All JpegLib files in Imaging include imjconfig.inc where MODE DELPHI is defined for FPC. Where did you add that {$mode delphi} that helped?

You can also change this in ImagingJpeg unit:
{$DEFINE IMJPEGLIB}
{ $DEFINE PASJPEG}
to
{ $DEFINE IMJPEGLIB}
{$DEFINE PASJPEG}
which will tell Imaging to use FPC's own pasjpeg. This seems to work without setting MODE somewhere.

I added it before uses line, it is that i tried to use vampyre with delphi 4, and edited the compiler definitions include a bit trying to get it to work with D4, but later i undoed it all (or i thought i did), so maybe it was this problem.

[Galfar]

I have found where the problem is:
{$I imjconfig.inc} is right after uses now in JpegLib, but MODE must be before uses to work. I had delphi mode hard-coded in fpc.cfg so I didn't notice anything (and it somehow worked in Linux and BSD). I'll update the files and commit them to SVN repository.

Did you have any success getting Imaging work in D4?

[Chebmaster]

Looks very appetizing. I'll try to use it in my engine.

No, i haven't tried since, but i got it to work with delphi 7 winxp and ported it flawlessly (100% same code works) to lazarus running in kubuntu linux

This library is worth gold, it's great for all sort of graphical utils and i think i'll use it in any further graphical apps i will be making (and i make quite some graphical manipulation tools for games), i can certainly already see how much pain it would save me if i had it 2-3 years ago.. (delphi & scanline & pixelformat mess)..

Good to hear it works ok, I mainly develop in Win32 and do Linux testing in Mandrake and Fedora x64 before major releases.

Well, that "mess" is basically why I started Imaging few years ago, originally for loading textures
without dependencies on VCL or some DLLs.

Any new features you would like to see in the library?

Not really, it's quite fast and it got all the important features i need, just the error message callbacks i mentioned in PMs.
