Nice.

BTW, there already exist applications in Lazarus for this job, MRIcron a MRIcronGL. I tried them ~ 1 year ago - worked well (although they are GTK2 app. and I run them on KDE4 distro).
See in gallery: http://wiki.freepascal.org/Lazarus_Application_Gallery#MRIcroGL

AFAIK there are more formats of MRI, not sure which ones are supported in MRIcron. Also, I don't know if MRIcron is open source.

MRIcron does not natively support DICOM IIRC, but there is apparently a conversion utility.

Nice.
Thank you very much!
See:

http://sourceforge.net/projects/ezdicom/
Written in Delphi(both), excellent work, and so much can be learned by studying the code.
Regards!

Also, with BGRABitmap it's easy to convert both app to Lazarus projects,
with some modifications.
Regards
p.s. Of course, read the license!

That's interesting.

What about adding image comparison using BlendImage or BlendImageOver (in case you use an alpha channel) ?

Code: [Select]
var
  img1,img2,comp: TBGRABitmap;
begin
  ...
  comp := TBGRABitmap.Create(img1.Width, img1.Height);
  comp.PutImage(0,0, img1,dmSet);
  comp.BlendImage(0,0,img2,boDifference);

I would recommend to make the GUI elements a bit darker (e.g. similar to the task bar on the bottom of the last screenshot) in order to make it easier to view the also dark X-ray images.

Circular, jwdietrich, thank you very much!
The problem is that I had not dealt with graphics,
relatively slow finding the necessary things and I have a lot to learn.
There are so many possibilities(BGRA)...
Thanks for the suggestions, I'll try to improve existing code.
Thank you very much and
best regards!
p.s. BGRA, amazing lib, thank you very much
