Vampyre Imaging Library 0.26 Released

[Galfar]

New version of Imaging was released few days ago.

0.26 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: ATI1N and ATI2N. Updated DDS file format 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 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, ...).

Ok, I found a time to try it, at last.
FPC 2.2.2:
The Windows version works without a notch.
The Linux version, hovever...

My modified OpenJpeg with dynamic loading generates AV at first attempt to decode a file. I'll look into it further: looks like I missed something.

On the other hand, maybe I do it the wrong way. There is my build script:

I removed fpc 2.2.2 and re-installed 2.2.0 but it still won't compile, the same "undefined reference to pow".

I'll look into in the next weekend. For now, I tried to find why it crashes when I use my dynamically loaded OpenJpeg, I traced the access violation to line 261 of ImagingJpeg2000,
more specifically, to
1: Pix^ := image.comps[Z].data[Y * Width + X] + Iff(Signed, $80, 0);
in
TJpeg2000FileFormat.LoadData
The Pix pointer hex value looks suspiciously low, maybe Bits is uninitialized?
Anyway, I have no more time today.
