Re: [Lcms-user] Null values for input or output profiles and ARGB

[Mart� Maria]

Hi,   Humm... a single profile has really no sense at all.   You cannot apply a single profile to RGB data. A transform needs two  profiles at least. E.g. "convert data from the RGB space A to RGB space B" But if you only specify a profile then to what space B is supposed to be converted the RGB data A?   All you could do with  a profile alone would be to convert data  to XYZ or Lab,  depending on PCS. In such case, you could use cmsCreateXYZProfile() or cmsCreateLabProfile() for output profile. Internally, lcms is doing a PCS exportation when  any of these profiles are found.   Regarding TYPE_ARGB_8, it works fine to me...?   Please give a try on the latest beta of lcms. It has a Delphi sample dealing with that: http://www.littlecms.com/ver110.htm If it doesn't work, then we could try to see what is going wrong.   Regards, Mart� Maria The little cms project http://www.littlecms.com [EMAIL PROTECTED]     ----- Original Message ----- From: Jon Hopkins To: '[EMAIL PROTECTED]' Sent: Friday, February 28, 2003 11:44 AM Subject: [Lcms-user] Null values for input or output profiles and ARGB Hi,   Is there anyway that I can use a null value for an input or output profiles so that I can just use say a scanner profile, or just the monitor profile? The other question I have is that the ARGB option I wanted for Graphics 32 in Delphi does not work correctly. I have used the suggested constant , TYPE_ARGB_8, to do this, as well as other combinations using SWAPFIRST_SH, DOSWAP_SH etc and none work. The library uses a 32-bit value with Alpha as the MSB and Blue as the LSB, is there a reason why this should not work?   Thanks,   Jon
