Thank you again -----Original Message----- From: Reem EL asaleh Sent: Saturday, December 25, 2010 5:23 PM To: Lcms Liste Subject: Single gamma value I am trying to build an RGB profile with a single gamma value of 2.2. I tried to use the cmsCreateRGBProfile() function and its work. However, it saves the TRC tags as ParametricToneCurve where the number of entries is 4069. I want to treat the TRC tags as a curve type with a single entry (i.e. rTRC = 2.2, gTRC=2.2, bTRC=2.2 for example). Which mean i want to be able to read and write the TRC tags with that type. I hope you can get my question. any clue how i can do that. Thanx and have a nice holidays. |
