[darktable-dev] Liquify feedback

[Moritz Moeller]

First of all: this looks awesome! It means yet another reason gone to 
exit DT and open Fusion or, worse, PS. Fantastic work.



Some comments.

The overlay looks nice but hides too much of what is going on in the 
image underneath. It would be great if


- opacity of the color overlay in the circles (or even blend mode)
- density of the arrows
- color of overlay (I guess arrows and circles share this)

could be adjusted. Maybe just add this the global prefs?

Another thing is that often one spends a long time creating a spline 
mask for some effect. Then it not unlikely that there is a shared edge 
between that spline and some liquify effect.


Being able to import from/export to the mask manager would be great thus.

Another important feature is exchange of warp points/lines/splines 
between liquify instances.


Maybe a global liquify manager would hold this data and each instance 
would just let you select which ones to use from the global list and add 
some local modifiers like strength (could be negative to allow inversion).




Cheers,

.mm


P.S.:
In the tool it says

warps|nodes count: X|Y

This is a bit confusing every time I read it because the '|' looks like 
an 'l' or 'I' or a '1'. how about:


warps, nodes: X, Y

or

warps/nodes: X/Y

Yes, darktable git master now requires gtk3 3.14+ to build.
The 3.14 was chosen because even debian stable has that version.

That is not a bug.
This was intentional.
Therefore this will not be fixed.

The solution is:
*). Either use stable darktable version (2.0.x), which still requires 3.10+
*) or keep using the git master at the moment just before gtk version
requirement was bumped
   Do note that it will no longer be considered a build of "git
master", and is perhaps more
   riskier than using the actual "git master".
*) Or update gtk, possibly by updating the system to something newer.

LTS is only about the packages present in said LTS release, it has
nothing to do whatsoever
with the choices about version requirement made by the developers of
the software...

Also see "[darktable-user] Compiling last git master failed because of
GTK-3 outdated" thread.

[darktable-dev] error during building current git on 14.04

[Nazarii Vitak]

Hi everyone,

I tried to update the darktable through git. The command ./build.sh ended
up in error.
Last lines from terminal:
"CMake Error at
/usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:108

As I understand it requires gtk3 >3.14, but I have found that installation
of gtk3 3.14 brokes unity. The only way is to upgrade the system, but I
usually do this when xx.04.2 LTS appears. Could it possibly be fixed to
build darktable at 14.04.
I have attached ~/darktable/build/CMakeFiles/CMakeOutput.log and
~/darktable/build/CMakeFiles/CMakeError.log.

If you need more information let me know how I can gather this information
and I try to obtain it.
