Yes, but note this would use the perceptual intent and will convert to sRGB. There is no such thing as "apply an ICC profile". Profiles are applied always as pairs, the source and the destination. The source is the colorspace the image data is in, the destination is the color space you want to obtain. In your case, you are converting to sRGB. Make sure the decoding is not already returning sRGB data. Otherwise I don't know internals of this lib. > $ wtpt file5.jp2.icm > Show media white of profiles, identifying black body locus. v2 Don't use this program, is very outdated.

Not really. intents don't apply because it is a matrix-shaper one. Just look for double color management somwhere else.
