Hi, I am new to Lazarus/FPC and I got a first problem with using LazIntfImage
under OSX:
My small program reads out ExifData and small Thumbnail-Pictures out the files
from different DigitalCameras. The thumbnails usually are quite small (between
320*200 and 570*375 px)
I keep this pictures within a TImage Object for later use. Since I want to
analayse the distribution of the RGB-Values, I read them out with
...pixels(x,y) function. Anything works fine here, anything correct in Windows
and OSX.
But this function is very, very slow. Even on OSX. So I tried to use
TLazIntfImage.
TLazIntfImage's access is fast, but now there is a problem: The values for RGB
under OSX are not correct anymore.
I know that I get a 16bit Value here, so I have to use something like
FPColor.red div 256.
The results are correct in Windows, but not in OSX. I already tried to
SwapEndian just anything I got,- no way.
I cant see any rule in results like this here:
Pixel (0,215): 65,43,20 (Mac), 88,57,21 (Windows)
Pixel (1,215): 53,38,26 (Mac), 73,50,31 (Windows)
Pixel (2,215): 50,38,21 (Mac), 69,50,21 (Windows)
and so on.
Maybe someone can give me a hint?
