[Solved] How do I use gradient in Gimp-2.7.x?

gerard82 · **Posted:** Wed Sep 28, 2011 9:43 am **(#1)**

GIMP Version: 2.7.x
Operating System: Linux
OS Version: Gentoo Linux
GIMP Experience: Beginner Level

Hi all,
I have taken the plunge and installed gimp-2.7.x in my regular user install next to 2.6.11.
I am working on something where I need to change the angle of a brush and 2.6.11 can't do that.
I know I can rotate the image instead but with a lot of layers it takes lots of time.
Please refer to the attached snapshot of my toolbox.
I have selected a gradient but how do I tell Gimp to use it instead of the foreground color?
Thanks in advance.
Gerard.

good question gimp 2.7 could do both easier than before

But remain the question here rephrased:
Where is a documentation of the NEW Gimp brush system ?

Obviously Help is not already updated but should be already something useful

On Gimp 2.7, Click dynamics > Random color, choose gradient. There are also the tilting, fade etc. options there

Thanks a heap Molly that works.
But you loose pressure.

I did the same thing in Gimp-2.6 but you can have gradient and pressure.
I would like to submit a bug,only I'll have to find out where.

You just need to create a new dynamics preset (I didn't have my tablet plugged in here but it does work). to match the old "colour from gradient" option:

That new brush dynamics tool needs a manual on its own.

I fear that is one of those things that you just need to be "aware of" and figure out how it can work for you.

Thanks for replying Rob.
I can't get what you have there.
I don't have "color from gradient".
Furthermore when I click on any of the Edit buttons I get a new window but everything is grayed out.
I am running the "snapshot" of yesterday from git.gnome.org.

Solved again through a workaround.
Here a snippet of /opt/share/gimp/2.0/dynamics/RandomColor.gdyn:

Code: Select all

# GIMP dynamics file

(name "Random Color")
(opacity-output
    (use-pressure no)
    (use-velocity no)
    (use-direction no)
    (use-tilt no)
    (use-random no)
    (use-fade no))
(hardness-output
    (use-pressure no)
    (use-velocity no)
    (use-direction no)
    (use-tilt no)
    (use-random no)
    (use-fade no))
(rate-output
    (use-pressure no)
    (use-velocity no)
    (use-direction no)
    (use-tilt no)
    (use-random no)
    (use-fade no))
(size-output
    (use-pressure no)
    (use-velocity no)
    (use-direction no)
    (use-tilt no)
    (use-random no)
    (use-fade no))
            .
            .
(jitter-output
    (use-pressure no)
    (use-velocity no)
    (use-direction no)
    (use-tilt no)
    (use-random no)
    (use-fade no))

# end of GIMP dynamics file
 

By changing "(opacity-output
(use-pressure no)"
to (use-pressure yes) I now have pressure with gradient.
Needless to say I'd much prefer Rob's way but alas that doesn't work here.

That is super cool, RobA. Thanks for posting it.

holy cow, thank you for sharing that video RobA.

Thanks Rob!
In the meantime all of a sudden I can edit everything like you showed earlier.
I copied the /dynamics files to my /home/ikke/.gimp-2.7 and enabled them in Preferences.
I also got my printer working.
Scanning still a problem. (see attached pic)
I am getting more and more impressed by the capabilities of 2.7 compared to 2.6.
One moment I thought that maybe I could do away with 2.6 but the plugins and scripts are still a problem.
Thanks again.
Gerard.

Feature was missing in 2.8 too so had reason to create a color by fade using this info RobA and it worked like a champ. Sad that they didn't make this option as intuitive as it was in all previous versions in GIMP. Crazy (i.e., what were the developers thinking? lol). Thanks RobA.

Thanks a bunch Rob this works really well in Sam and Parthas Portable Gimp-2.8.1 also.

I would also like to add i tested it in the RGGJAN version (Gimp-2.7.3), and it works as well.
