MATLAB: How to tell if a tif file contains an embedded ICC profile

iminfotif

I am asking and answering the following question in case it helps someone.

Is it possible to use Matlab to check if a tif file contains an embedded ICC profile ?

Best Answer

Yes, using imfinfo as follows.

fileData = 'corn.tif'; % Example matlab file that doesn't have an ICC profile embedded
a = imfinfo(fileData); % Get info about the file
isIccEmbedded = isfield(a, 'ICCProfileOffset'); 
% Since no ICC profile is embedded, this is false

% Go through Step 5 at the following website to create an example tif
% with an ICC profile embedded,
% https://blogs.mathworks.com/steve/2009/10/20/embedding-an-icc-profile-into-a-tiff-file/
fileData = 'peppers.tif';
a = imfinfo(fileData); % Get info about the file
isIccEmbedded = isfield(a, 'ICCProfileOffset'); 
% Since an ICC profile is embedded, this is true

I saw this mentioned in the iccread help file and thought an example would be useful.

MATLAB: How to apply an ICC profile from one image to another image

"iccread" can read independent/standalone profiles and also the profiles embedded in TIFF files. However, "iccwrite" can only write a standalone profile file.

In order to apply the ICC profile you have from image1 to image2, you can follow the following workflow instead:

1. Save the ICC profile from the SVS file:

>> P = iccread('image1.svs');

2. Create a temporary ICM file (for use in step 3):

>> iccwrite(P, 'temporary.icm');

3. Now that you have an ICM file from the SVS file you had, you can apply this to your TIFF image using the workflow described in the following documentation:

MATLAB: How to embed an ICC color profile in a JPEG file

Here is how to embed an ICC color profile in JPEG file.

Step 1. Download Phil Harvey's ExifTool from https://exiftool.org: for PC the "Windows Executable" and for Mac the Perl library.

Step 2. Change the ExifTool name: for PC from exiftool(-k).exe to exiftool.exe and for Mac from exiftool to exiftool.pl.

Step 3. Locate the ICC color profiles on your hard disk. The file names of some of the most common profiles are sRGB Profile.icc and AdobeRGB1998.icc.

Step 4. Execute the code below, in which you adapt the paths of your image, ExifTool and ICC profile files.

Note: If you wish to embed an ICC color profile in a TIFF file, follow Steve Eddins's advices at https://blogs.mathworks.com/steve/2009/10/20/embedding-an-icc-profile-into-a-tiff-file/.

% Image file location (change as needed).
image_url = fullfile('image_path','image.jpg');
% ICC color profile file location (change as needed).
icc_url = fullfile('icc_profiles_path','icc_profile.icc');
% ExifTool file location (change as needed).
if ispc
    exiftool_url = fullfile('exiftool_path','exiftool.exe');
else
    exiftool_url = fullfile('exiftool_path','exiftool.pl');
end
% Copy ICC color profile from ICC definition file into image file.
icc_embed_status = system(...
    [ '"', exiftool_url, ...
    '" -q -tagsFromFile "', ... 
    icc_url, '" -ICC_Profile "', ...
    image_url,'"' ]);
% Delete image backup file produced by exiftool.
if icc_embed_status == 0
    delete([image_url,'_original'])
else
    icc_status = 'No ICC color profiles embeded in JPEG files.';
end
