Hi there,
I can load 16Bit TIFF via:

img->IO->NativePixelFormat = false;
img->IO->LoadFromFile("D:\\16bit.tiff");
img->IEBitmap->AutoCalcBWValues();


But if I want to append this Image to a TImageEnMView it remains blank.


img2->AppendImage(img->IEBitmap);


Also

img2->MIO->NativePixelFormat = false;
img2->MIO->LoadFromFile("D:\\16bit.tiff");
TIEBitmap *b = img2->GetTIEBitmap(0);
img2->GetTIEBitmap(0)->AutoCalcBWValues();

remains blank.


Can anyone can give me a hint, what Im doing wrong?

Thanks in advance
Alex

Hi Alex

Did you try calling:

img2->ReleaseBitmap(0, True);


After the code above?

Sorry, please try with StretchValues to lock in the Black and white values:

img2->MIO->NativePixelFormat = false;
img2->MIO->LoadFromFile("D:\\16bit.tiff");
TIEBitmap *b = img2->GetTIEBitmap(0);
b->AutoCalcBWValues();
b->StretchValues();
img2->ReleaseBitmap(0, True);
