Hi,
My first problem is to dump the gammatable into an array of string for output.
gamtbl:=cmsReadICCGamma(hSrc, StrToInt('$' + '72545243'));
gamest:=cmsEstimateGamma(gamtbl);
So I get the result approximate 1.8 by using eci.icc
But how did I get the real values instead of the EstimateGamma?
gamest^.GammaTable[]
You can also access the number of entries in the table by using gamest^.nEntries
My second problem is to dump the Look-Up-Table into an array of string for
output.
Ops, here the problem comes evident. A LUT may have a lot of different
implementations,
not only one table. In fact it was so hard than I didn't include in the Delphi
wrapper,
that is the reason cmsReadICCLut is not there. Maybe you could convert the C
structure
to Delphi. If you want to give a try, it is located in lcms.h, struct
_lcms_LUT_struc
But be careful because it is not part of the API and thus may change across
lcms revisions.
(it has changed in 1.15)
Regards

Subject: [Lcms-user] dump tables
Hello,
unfortunately I have some more questions about using your library (lcms.dll).
I hope you're able to answer all these questions and I didn't take too much of
your time.
I'd like to program an application like the "ICC-Profile Inspector" (with
Delphi).
My first problem is to dump the gammatable into an array of string for output.
gamtbl:=cmsReadICCGamma(hSrc, StrToInt('$' + '72545243'));
gamest:=cmsEstimateGamma(gamtbl);
So I get the result approximate 1.8 by using eci.icc
But how did I get the real values instead of the EstimateGamma?
My second problem is to dump the Look-Up-Table into an array of string for
output.
To use the "cmsReadICCLut" function, I had to insert the following program
lines into the lcmsdll.pas:
Function cmsReadICCLut (hProfile: cmsHPROFILE;
Sig: icTagSignature): LPLUT; StdCall;
Function cmsReadICCLut (hProfile: cmsHPROFILE;
Sig: icTagSignature): LPLUT;
EXTERNAL 'lcms.dll';
The result I get is a Pointer (LPLUT).
Could you explain me how I can handle the LPLUT-Pointer to
get the Input and Output values of the Look-Up-Table.
Regards,
André K.
