The profile conversion for 16 bit images does not work.
The result is a black screen.
Works if ie48RGB is replaced with ie24RGB, but this is not allowed.
Also, when loading 16-bit PNG images, they are automatically converted to 8-bit images. So it should not be.
IM1.LegacyBitmap:=False;
IM1.IO.NativePixelFormat:=True;
IM1.IO.LoadFromFileTIFF('D:\IMProf\16.TIF');
ICC:=TIEICC.Create;
try
ICC.Assign_AdobeRGB1998;
ICC.ConvertBitmap(IM1.IO.IEBitmap, ie48RGB {ie24RGB}, ICC);
finally
ICC.Free;
end;

Hi
ie48RGB conversion was not supported, but we have added it now. Please email me for a pre-release of the next version.

When you assign the profile to the bitmap and save the image back, does your resulting image still has the profile attached ?
A way to tell it is to open it in photoshop and see if it tells you that there are no profile attached to the image.

| I have a task, full color correction of 16 bit images, but so far I can not even do minimal actions, downloading and converting to the ICC I chose. I have a demonstration set of files, only DCU files. There is a desire to buy a component, but what I need is not implemented. I hope the full support of 16 bit images will appear soon. |

Hi
There are some areas of ImageEn where ie48RGB is not yet supported, but we are implementing support as demand calls for it.
We have implemented it for profile conversion now. If there are other areas where you need ie48RGB support, let us know.

Thanks Nigel, but i have not find a way to save an ICC profile with the image. When I open any images in photoshop, i always get the message that no profiles are attached with the document. Is that something that can be implemented in the future ?
Thanks |

The InputICC profile docs says that the profile is removed after being applied. This is my code in the oncreate event
IERegisterFormats;
IEGlobalSettings.AutoFragmentBitmap := False;
// Apply color profile before rendering
IEGlobalSettings().EnableCMS := True;
IEGlobalSettings().ApplyColorProfileOnRendering := True;
ImageEnVect.IO.NativePixelFormat := True; // this says "convert to RGB"
ImageEnVect.IO.params.BMP_HandleTransparency := True;
ImageEnVect.IO.params.DefaultICCProfile.LoadFromFile
(EmbeddedDM.helppath + '\sRGB2014.icc');
If i load an image with any profiles attached to it and save them back, load them in photoshop, it will tell me that this document has no profile attached.
You can download a trial of photoshop. Under edit-->color settings, be sure to check the 2 boxes that say "Let me know about profile mismatched"

Hi
If EnableCMS = False, does Photoshop still report no profile?

Interesting. It will keep the embedded profile then. I load an image with the adobe profile but want imageen to convert it to srgb. So i use the convertbitmap command. I save the file back and open it in Photoshop. It does not strip the profile anymore but keeps the original profile that was loaded. see attached.

OK, cool. Now use the following:
IERegisterFormats;
IEGlobalSettings.AutoFragmentBitmap := False;
// Apply color profile before rendering
IEGlobalSettings().EnableCMS := True;
IEGlobalSettings().ApplyColorProfileOnRendering := True;
ImageEnVect.IO.NativePixelFormat := True; // this says "convert to RGB"
ImageEnVect.IO.params.BMP_HandleTransparency := True;
ImageEnVect.IO.params.InputICCProfile.LoadFromFile(EmbeddedDM.helppath + '\sRGB2014.icc');

Hi
This code successfully wrote the profile in my testing:
IEGlobalSettings().EnableCMS := True;
IEGlobalSettings().ApplyColorProfileOnRendering := True;
ImageEnView1.IO.NativePixelFormat := True; // this says "convert to RGB"
ImageEnView1.IO.LoadFromFile( 'D:\201849018_A1.jpg' );
ImageEnView1.IO.params.InputICCProfile.LoadFromFile('D:\sRGB2014.icc');
ImageEnView1.IO.SaveToFile( 'D:\Test_SRGB.jpg' );

Nigel, indeed it does work. So something somewhere is removing the profile before i save it.
Let me troubleshoot.
Thank you very much
Best

Hi Pierre
As you have EnableCMS = true, ensure you load the profile after you have loaded the image.

| I need the functions of a RAW converter. To do this, i need a full work with the image in the mode ie48RGB. Color correction, histograms. Exposure, Contrast, Lighting, Shadow, White, Black, Saturation ... Applyng ICC. Saving as a TIFF RGB 16Bit / Channel. |

Hi
I've added wider ie48RGB support to our to-do list. To raise its priority please add and vote for it on our uservoice page:
