Can you save in a 16 bit per channel format ? I loaded a few full app demo and I am able to load 16 bit per channel TIFF file that came from a RAW file. When i save them back and load them into photoshop, they are 8 bits per channels.
Maybe the photo full app convert them but I do not see any conversion code.
I am just wondering
Thanks

Hi

Have you enabled NativePixelFormat?

I do have the nativepixelformat set to true in my oncreate event. And legacybitmap is set to false in the component.

Let me do more checking with some simple demos if it is supposed to work.
Thanks

I downloaded the photoen source. I added iamgeenview1.io.nativepixelformat := true to the oncreate childwin event.
I loaded the 48 bit PSD file and saved it back. from 16bit per channels, it goes back to 8 bit per channel.

Hi

I tried both the following methods:

  bmp := TIEBitmap.Create();
  bmp.ParamsEnabled := True;
  bmp.Params.NativePixelFormat := True;
  bmp.read( 'D:\16bit.psd');
  bmp.write( 'D:\16bitDONE.psd');
  bmp.free( );

  ImageEnView1.IO.NativePixelFormat := True;
  ImageEnView1.IO.LoadFromFile( 'D:\16bit.psd');
  ImageEnView1.IO.SaveToFile( 'D:\16bitDONEIE.psd');


In both cases it appears to be correctly saving the PSD file with 16bits per channel (although I don't have PSD on this system to double-check).
