Wrapper for Little CMS JpegICC tool for stripping color profiles and changing image colorspace.
var ICC = require("ICC");
var icc = new ICC();
icc.intent(2);
icc.quality("90");
icc.blackpointCompensation(true);
icc.process("test.jpg", "testout.jpg", function(err) {
if (err) {
console.log("JPEG ICC returned an error:");
console.log(err);
return;
}
console.log("Succesfully processed test.jpg");
});
npm install jpegicc
Also make sure jpegicc is installed. See Little CMS for binaries and a link to SourceForge, or download directly from SourceForge

preserveBlack <-- Preserve black (CMYK only) 0=off, 1=black ink only, 2=full K plane
ignoreEmbeddedProfile <-- Ignore embedded profile (boolean)
embedDestinationProfile <-- Embed destination profile
saveEmbeddedProfile <-- Save embedded profile as <new profile>
precalculatesTransform <-- Precalculates transform (0=Off, 1=Normal, 2=Hi-res, 3=LoRes) [defaults to 1]
softProofProfile <-- Soft proof profile
softProofIntent <-- SoftProof intent

quality <-- Output JPEG quality (0 - 100)
