Object to display NEF-file
lazarus / 39-Graphics

Hi all,

I own a harddisk with about 2500 NEF files (pictures in the Nikon NEF-
format). I'm trying to write a progam in Lazarus to order/rename those
files. It would be nice to display them on the screen. However, the
TImage-component doesn't support the NEF format, and I don't want to
convert them to another format (jpg/bitmap).

I've read a lot about DCRAW and LIBGFL but can't find any simple
example to display my nef-pictures. Does anyone know a simple
example/component? Thanks in advance.
Best regards,
Hendrikus.

There is a codec for Windows on the Nikon web for download witch could
help eventually.
The NEF-format is something like raw

MacWomble,  thanks for your reply,

I know there is a codec for Windows, I've already installed it on my
Windows10 laptop. But I still can't figure out how to display the
nef's
in a Lazarus Timage.
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var s:
String;      oPicture: TPicture;begin     s :=
'D:\DATA\NEF\_MVZ7116.NEF';     oPicture := TPicture.Create(Nil);   
 Try           oPicture.LoadFromFile(s);           ....     Finally  
     FreeThenNil(oPicture);     end;end; 
compiles fine, but I get a runtime error that NEF is an unsupported
fileformat.
