How can I apply an ICC profile from one image to another image?

I want to get the ICC profile from a WSI image (.svs format) and apply it to a TIFF image.

However, when I used "iccwrite" to do this, it corrupted my TIFF image instead:

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

>> iccwrite(P, 'image2.tif');

>> imread('image2.tif')

Error using imread (line 362)

Unable to determine the file format.

"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:
