Just add -lm to the linker flags in the Makefile. I don't have
access to the sources right now, so I can not be more specific. If
you need more information, just let me know and I'll try to come
up with better instructions.

Hi Marti,

thanks for your tips, it works fine.
You new web site is very nice.

Your delphi sample is very interesting in particular concerning the icc =

thanks

  Hi,

  Just build your own descriptor:

  #define TYPE_LabA_8      =
(COLORSPACE_SH(PT_Lab)|CHANNELS_SH(3)|BYTES_SH(1)|EXTRA_SH(1))

  In delphi this equals to $a0099=20

    Hello,

    in a 24 bits bitmap, instead of storing rgb value I store Lab value,
    I do some process and then I convert it to RGB with

    cmsDoTransform(hTransform, TheScanline, TheScanline, TheWidth);
    where
    hTransform :=3D cmsCreateTransform(LabProfile,
                    TYPE_Lab_8,
                    DisplayProfile,
                    TYPE_BGR_8,
                    INTENT_PERCEPTUAL,0);

    it works fine

    now I want to do the same with a 32 bits picture where instead of =
Having RGBA I have LabA

    but now how can I do my transform with scaline? the problem for me =

    Any idea?

Yep, so, Kylix access can be done, since lcms can be linked as shared

Of course, it is possible and in fact it's quite trivial thing. Please,
find the posting with subject "Huge .so files" in the newsgroup

Hi 

> Is there a kylix version planned for LCMS?

Not by now... I have no access to Klinx, but probably it could be done
if Klinx is capable to use C routines. lcms does work in a multiple platforms,
so the only question would be interfacing liblcms.a with Klinx. 

Do you know if Klinx can somehow call C code?

Ops, this should be done yet. Too few time and may things to do ;-)
Also, a Qt demo would be nice. I will left for next revision.

Re: [Lcms-user] Kodak patent infringement?

[<ma...@li...>]

Hi,

Well, I'm not a lawyer, and of course this *could* have legal implications,  so, this is my tech-only point of view:


 4,500,919
========
"A system for reproducing a color original in a medium using a selected multiplicity of reproduction colorants, comprising: a
scanner for producing from said color original a train of appearance signals dependent on at least three color values of said
original; aesthetic correction circuitry for introducing aesthetically desired alteration into said appearance signals to produce
modified appearance signals; and colorant selection mechanism for receiving said modified appearance signals and for selecting
corresponding reproduction signals representing values of said reproduction colorants to produce in said medium a color match of
said modified appearance signals"

This could refer to profiles.... lcms does only implement the mechanics for profile interpretation
as described by International color consortium (ICC) www.color.org . lcms does NOT characterize
any device, and does NOT introduce any aesthetic correction. Is up to the profile (and then up
the profile generator) to embed such corrections in profile. Also, seems unapplicable to lcms, since
there is no scanner involved. Another question is lcms could be used to build such system, but lcms
does'n give this functionality out of the box.

5,432,906
=======
"A method and apparatus for generating a modified electronic image combines multiple image transforms into a single composite
transform, and then modifies the electronic image in accordance with the composite transform. The composite transform includes
sample values sequentially modified in accordance with each of the multiple image transforms being combined. The method and
apparatus further provides a user interface allowing a user to select individual transforms for composition. The use of a
composite transforms allows a user to interact with the image processing system more quickly and interactively while obtaining a
desired modified image. "

This patent is holded by Kodak, and is a bit more complex. Seems they have patented just the icc
way to handle color management... However, again, lcms does NOT implement all they describe.
lcms does NOT have any user interface (it acts as a daemon). Also, (and this is surprising, but true)
the profiles DOES NOT hold sample values, but the complete algorithm to convert between
colorspaces. lcms DOES smelt multiple image transforms into a single composite transform, but as an
option selectable by programmer. Anyway, without this smelting, color management is so slow that is
unuseable. These composite transforms are described by ICC as "device link profiles", and thus,
supported by lcms as being part of the ICC standard.


Again, don't take too seriously my comments. I'm not a lawyer, and this, of course, could cause
problems with Kodak. lcms is intended to be a portable CMM engine to be used by programmers,
not as a color management system for final users. I assume people using  it are aware lcms can be
used to build systems that breaks patents, but lcms per se isn't. Or at least that is what I belive.

Humm... If I remember correctly, java does have some similar to lcms in awt, and  seems nobody
worries about patents on that.

Regards,
Marti.

Yes, that is. It works in such way assuming then you would need only one
transform.If you don't give those flags, then the result is the image viewed on
monitor. If you give flags and printer profile, you can check the gamut of printer
or emulate printer output. Giving no flags and printer profile = NULL is same
that cmsCreateTransform().  cmsCreateProofingTransform() is somehow a
"superset" of   cmsCreateTransform()

Marti.

Re: [Lcms-user] Profing

[<ma...@li...>]

Hi,

cmsCreateProofingTransform() can do two  things

- Check gamut to see if a color is reproducible by a device. This always works
- Emulate a device. For example: See how will look a image when printed
  whithout printing. Printer profiles has gamut remapping, and thus, could
  change colors. This works only if adequate tag is present.

By default cmsCreateProofingTransform() does nothing (well, acts 
as a "normal" transform). Then, including one or both flags you add 
the desired function on "Proof" profile. cmsCreateProofingTransform uses
3 profiles, one for input, describing the image,  one for monitor and a 
third for the profile being proofed.

> is there a tag for ABSOLUTE COLORIMETRIC?

No. Is up the CMM to build absolute colorimetric intent using relative
colorimetric or perceptual one. If you have access to icSigPreview1Tag                    
or icSigPreview0Tag, you got absolute colorimetric as well.

Regards,
Marti.

[Lcms-user] Profing

[<ma...@li...>]

Hi Armindo,

lcms 1.08 does support gamut checking even if no tag is present,
this is new in this revision, and still not checked extensively, but seems
to work well on my profiles. 

Proofing as emulating the target device still needs preview tag, and 
probably will need it on future revisions, since this is a task of the profiler
instead of the CMM.

To enable gamut checking you need to add cmsFLAGS_GAMUTCHECK on flags
when calling cmsCreateProofingTransform(), for target device emulation, add
cmsFLAGS_SOFTPROOFING. Note that those flags only works on 
cmsCreateProofingTransform(), and NOT in normal transforms.

To know if a profile does support softproofing, check the existence of tags:

 icSigPreview0Tag                    = 0x70726530,  /* perceptual */
 icSigPreview1Tag                    = 0x70726531,  /* relative colorimetric */
 icSigPreview2Tag                    = 0x70726532,  /* saturation  */

with 

    cmsIsTag(hProfile, <tag>)

If the tag is present, profile does suport emulation. Printer profiles often has such tags.

> it seems that the 1.08 works fine with delphi.

Great! with this,  I hope to be able (finally!) to release both new packages
on next week. Thanks for the testing.

Best Regards
Marti.

Hola Marti,

I would like to do proofing so a few questions :

how could I know if a specific profile can alow proofing?

I would like to make a colorpicker that alow me to select only printable
colors.

So for this I must know if the printer profile alow proofing.

Any suggestions for doing this?

Hi,
I've put the final beta of ver 108 in site. Now the linux package
is supposed to be functional. There are two profilers, one for monitor
and one for scanner working under Gnome (with Qt) and KDE, as well
as a measurement tool.

http://www.littlecms.com/ver108.htm

If anybody has such platforms (Gnome w/ Qt, KDE or any machine with X11/Qt
installed) and want to check, please drop me a note, just to know if it works.

Not currently. Graeme Gill has a free tool doing this, in his argyll =
cms.=20
http://web.access.net.au/argyll/argyllcms.html

Unfortunately, argyll is still a work in progress, and his tool only can =
dump gamut=20
of forward transforms (scanners) and doesn't work in reverse way =
(printers). He is=20
using VRML as a visualization tool.=20

I will add this on my wish-list for incoming revisions.

> stylus color 860, CIELab (from spectrocam ) to RGB (printer) ), =
impressive result!!

Glad to hear, :-)  thank you!
Best regards,
Marti.

  Hi Marti,

  any plan to include in lcms the possibility to show the gamut of a =
profile in 3D?

  PS : I have tested lcms with Monaco proof (in this case printer =
profile (epson stylus color 860, CIELab (from spectrocam ) to RGB =
(printer) ), impressive result!!

  thanks

Hi Marti,

any plan to include in lcms the possibility to show the gamut of a =

With Monaco you can select only one....

Most printer profiles does contain ALL intents. If you choose an intent which is not 
supported by the profile, lcms reverts to perceptual (that is always supported)

There is a function to know if a open profile does support a particular intent

        cmsIsIntentSupported()

Oh! Thanks. Not now, but for shure I will ask your advice for this on future.

Best regards,
Marti.
