Hi,<br>
<br>
Just to react on this :<br>
<blockquote type="cite">and "Color" modes work exactly as in
Photoshop</blockquote>
Just to inform the way 'color mode' works in Gimp 2.6 is superior to
the 'color mode' of Photoshop ( till Cs2 for sure ).<br>
This can be tested & seen with comparing the same file open like
this :<br>
<a href="http://www.davidrevoy.com/XYZ/color-mode_test_GIMP-net.jpg">http://www.davidrevoy.com/XYZ/color-mode_test_GIMP-net.jpg</a><br>
<a
href="http://www.davidrevoy.com/XYZ/color-mode_test_TOSHOP-net.jpg">http://www.davidrevoy.com/XYZ/color-mode_test_TOSHOP-net.jpg</a><br>
useless to say that Gimp color mode is far superior for artist than
Photoshop. I understand the photoshop one should be proposed for
compatibility, but for efficiency ; please don't omit one like Gimp.
I couldn't try it with Krita , btw*<br>
<br>
The PSD file if you need to test ( this file can be considered as
'public domain' if you need it ) :<br>

( PS : can't compile since Git or install 2.3 threw PPA , as i'm
Lucid Lynx LTS user not Maverick ...so I wait kubuntu backport to
post the bin for Lucid 64bit )<br>

<div bgcolor="#ffffff" text="#000000"> Phew... I think I've
gone a bit mad with the blending modes :D.<br>
I added a few. When counting everything together there
should be nearly 40 compositing modes now.<br>
All modes should trait partly transparent layers as
Photoshop is doing it and all modes should<br>
respect the channel flags.<br>
But there are two problems with this patch:<br>
<br>
1. I used a pretty generic approach. So it relies on the
compiler to do proper inlining. And i didn't use the
optimized multiply functions. I had a few problems with
those functions, because it seems the give no correct
results but approximations. So I still need to check out
which composite modes will work with the optimized
functions. I just want to say that it could be that this is
a bit/much slower then the current implementation (i don't
know how much time you spend in optimizing this).<br>
I personally haven't noticed any speed impact but I've got a
3GHz quad core, so i think i will be the last<br>
who will notice this.<br>
<br>
2. The "Hue" and "Saturation" modes are not working
correctly but the "Luminosity" and "Color" modes work
exactly as in Photoshop. I coded the algorithms after the
ISO 3200-1 spec. Adobe released the texts they gave to the
ISO committee for specification. You can find them here:<br>
<a moz-do-not-send="true"

(direct link)<br>
<br>
go to the category "Transparency" -> "Basic Composition
Computations". This spec is of course for PDFs but it seems
that Photoshop uses the same formulas.<br>
Since "Luminosity" and "Color" modes are working i think i
made some mistake in implementing the<br>
"setSat" function (on page 327). Maybe someone else has an
enlightenment, because I'm working in the dark right now :D.<br>
<br>
But apart from this two problems everything else should
work fine (hopefully).<span style="border-collapse:
