Re: [Lcms-user] icclink - device Link profiles usage
Hi, I tried using jpegicc for softproof and had no success with tho following: jpegicc -m3 -p cmyk.icc sRGB.jpeg sRGB_softproof.jpeg You are right. There is a bug in jpegicc that prevents softproofing. Thanks for let me know. Here is a fixup: File jpegicc: hProof = NULL; if (cProofing != NULL) { hProof = OpenStockProfile(cProofing); } } Replace by: hProof = NULL; if (cProofing != NULL) { hProof = OpenStockProfile(cProofing); dwFlags |= cmsFLAGS_SOFTPROOFING; } } I'm adding it to master sources.

Re: [Lcms-user] icclink - device Link profiles usage
Hello again, What about using abstract profiles? I have problems understanding the Syntax of icclink. There is an Example in the manpage: icclink -t1 -x -o softproof.icc *Lab cmyk.icc cmyk.icc *Lab I creates an abstract profile. I tried to adapt it to use with sRGB-image-data, finding out, that I actually don´t understand it. Can you tell me how the order in the mentioned Example leed to a proof? While experimenting the resulting profile switched between Abstract and DeviceLink-Profile. How can I ensure to have an (embedable) Abstract profile as result? Thanks Thorsten Marti schrieb: Hi, In theorie i would: - transform source to simmulation with perceptual intend - step 1 - transform step 1 to output with absolute rendering intent (I want to simmulate th paper whitepoint) This would almost work. Is just a little bit more complex, as the softproof requires mixing intents. The complete workflow would be something like: Input(RGB)- [Perceptual] - Proof(CMYK) Proof(CMYK) - [Rel.colorimetric] -Proof(Lab) Proof(Lab) - [Abs.colorimetric] - Output(RGB) lcms implements that by the softproofing transform, which takes care of all the details (BP compensation, gamut check and so) Current version of icclink does NOT uses this kind of color transforms, so you have to write a small program in order to embed this transform into an ICC devicelink. Having said that, maybe a devicelink is not your best option, as you plan to use it as input profile (W3C doesn't allow devicelinks AFAIK) Hope this helps Marti Maria The littleCMS project http://www.littlecms.com - Original Message - From: Thorsten Krug [EMAIL PROTECTED] To: lcms-user@lists.sourceforge.net Sent: Monday, December 19, 2005 7:01 PM Subject: [Lcms-user] icclink - device Link profiles usage Hello, I´m not sure, if i do understand the device-link-profiles (DLP) in the right sense.
