Re: [Gimp-user] What is the scale of Levels?

Hi David,

Obviously, you're more concerned about the mailing list. I know about
flame wars and never do that. I do 100% agree that I should have
emailed him personally on his own email address instead of this list
but it's really shocking to read your stern reply. Does the freedom to
say what you want to say really mean that you can say _whatever_ you
want??? And, that too on a public mailing list??? Is _that_ an
etiquette ? Aren't you hurting the feelings of so many thousands on
this list by posting such offensive language/quotes on a public
mailing list? Now who is hurting who? Can't you really see that that
very offensive quote can start many flame wars now and in future? It's
not me - I am not flaming. It's the quote.

I don't have anything personal against you or Darxus but posting such
offensive quotes on a public mailing list is way too offensive and can
really start way more than a flame war.

Please stop it.

 No doubt you disagree with that (I do not, myself.). Regardless, the
 topic that you brought up (and especially the way you brought it up;
 you are not the arbiter of 'inappropriate language for God', nor does
 the way you presented your *opinion* as if it were *factual* speak
 well of your honesty.) is one that is commonly regarded as one that
 should not be brought up, as a matter of etiquette, on a public
 mailing list.

 If the issue of another person putting particular quotes in their
 email signature bothers you, I suggest you email them privately and
 leave all mailing-lists out of it.
 It's far less likely to result in a flame war than what you did do
 (post to a public mailing list attempting to get Darxus to change his
 behaviour on account of your *opinion*)

 
 Flaming
 Flaming is the practice of attacking people on a personal level.
 While flaming is relatively common on the internet, almost everybody
 will claim they're opposed to it. They may even flame you for having
 flamed someone. It's all really confusing, actually.

 However, there are some fairly obvious things. Responding to
 someone's analysis of the deficit crisis by telling them that they
 probably walk funny or weren't breast fed could easily classify as
 flaming. Making rude comments about an individual's sexual organs or
 religion would also probably classify.

 Personally, I stick to a simple rule: **I say nothing about
 anybody that I can not back up with facts. I do not comment about
 people's religions, their eating habits, whether or not they smoke,
 etc**. If I decide to comment about someone's level of intelligence, I
 make sure I have good examples to support my comment. But even then, I
 do this very rarely.
 
 **emphasis** added by me.

[Gimp-user] Problem porting 1.x-Perl script to 2.x

2009-08-25 Thread Michael

Hello,

I'm trying to use a Perl script that makes use of Perl's Gimp module (the
simplified version Gimp::Fu) for Gimp Gimp versions 2.x. (I have GIMP 2.6.2
under OpenSUSE 11.2).

Whenever I try to execute the script from the Filters  Perl-Fu menu option I
get error messages like:

 Calling error for procedure 'gimp-procedural-db-proc-info':
 Procedure 'gimp-gimp-image-new' not found.

The funny thing is that my procedures are correctly called in the script
('gimp-image-new', 'gimp-layer-new' ...), but somehow a 'gimp' is prepended
here.

Have you seen this before? How can I solve the problem?

Thanks in advance for your help,

Michael

[Gimp-user] how to use layers

2009-08-25 Thread thomas w.
I've read the documentation several times and every tutorial I could get my
hands on, but I still can't make any sense out of how to properly use
layers..

For example, I want to merge two pictures, by taking some regions from one
picture and some from another. I though I could do this by making unwanted
regions transparent - this seems obvious. I also tried some other techniques
basd on a few tutorials, but none seemed to work well.

But I simply don't get results that make any sense. The vagueness of the
docuemntation and being unable to find any other guide is not helping.

Is this a case where GIMP simply makes it so difficult compared to Photoshop
that I'd be better off buying a Windows machine and using Photoshop?

I wanted to use GIMP for my photo manipulation. I had assumed after all these
years that it was usable. I hope I'm not forced to go to Photoshop over
something simple like this.

If there's no chance that GIMP can be used as efficiently as photoshop,
perhaps it would be sensible to give up sooner rather than later. But this is
a big expense for me, at the least I'll need to buy a second machine, or give
up on Linux on the desktop altogether.

It's so tragic that after all these years, GIMP's user interface has seen no
improvement. I had hoped that at least the documentation would be useful.

The best way to merge two pictures is probably to copy the relevant part
of the first one (make a selection with one of the numerous tools and
copy it) and then to paste it into the other picture. Then you have a
new floating selection on this picture, and you may decide whether you
want to immediately merge it into the background, or probably better,
you prefer to make it a new layer.

 But I simply don't get results that make any sense. The vagueness of the
 docuemntation and being unable to find any other guide is not helping.

I'm much more suspecting the vagueness of your explanations: what
exactly are you doing, and what results do you get?

 Is this a case where GIMP simply makes it so difficult compared to Photoshop
 that I'd be better off buying a Windows machine and using Photoshop?

Certainly not. Using layers is really basic in GIMP, and anybody can
manage to do this. By all means, don't buy anything more, you already
have all what you need!

 I wanted to use GIMP for my photo manipulation. I had assumed after all these
 years that it was usable. I hope I'm not forced to go to Photoshop over

GIMP is very suited to photo manipulation. Ask the proper questions and
you will get useful answers.

 If there's no chance that GIMP can be used as efficiently as photoshop,
 perhaps it would be sensible to give up sooner rather than later. But this is
 a big expense for me, at the least I'll need to buy a second machine, or give

Already said, already answered.

What are your specific criticisms about the interface and the
documentation?

Hi,

This seems like the first thing you need to grasp about layers: layers 
are not supposed to be merged, the whole point of layers is that they 
allow you to divide an image into several independent parts.

Instead of merging, you could add a layer mask to the top-most layer and 
get rid of the parts you don't want using the mask.

 It's so tragic that after all these years, GIMP's user interface has seen no
 improvement. I had hoped that at least the documentation would be useful.

GIMP development happens slowly but steadily. Being completely ignorant 
about the efforts that have been made to improve the GIMP UI lately is a 
good way to demotivate further work to be done. Just have some patience, 
or better, help us improve GIMP instead of complaining.

BR,
Martin

The GIMP docs team hasn't made a release of the user manual for GIMP 2.6
yet. All you can do at this point is using the installer for the last
release, which handles GIMP 2.4. It is available from

GIMP is really good for photo post-processing. I use it a lot; even
though I bought a laptop with some stuff preinstalled, photoshop
elements included. I gave it a couple tries, but I feel more comfortable
with the Gimp (despite the fact that for some particular images I like
the sharpening tool best that the filters/enhance/unsharpen mask in the
Gimp. Overall, I have ended by no using PE at all.

 If there's no chance that GIMP can be used as efficiently as photoshop,
 perhaps it would be sensible to give up sooner rather than later. But this is
 a big expense for me, at the least I'll need to buy a second machine, or give

The Gimp is a complex and powerful tool, which means it has a learning
curve. But it is not by any means less efficiently usable than
photoshop. If anything, you could say about the lack of support for CMYK
(it is on the way) and bit depth = 8 (improving this is in the way too).

 
 It's so tragic that after all these years, GIMP's user interface has seen no
 improvement. I had hoped that at least the documentation would be useful.
 

Concerning to the UI, I'd say that it is matter of tastes. I really like
the Gimp UI; it feels less crammed with stuff, as you can work directly
on the image window, and by using the tab key bring the tools window
back and forth. I really hope the Gimp developers are not planning to
'photoshop-ize' it!.
And the documentation is useful enough!

For advise with how to set the layout in the UI, as well as for the
layers stuff, I really recommend visiting http://meetthegimp.org. For a
lazy guy like me, it really made the difference!
In about 10 chapters, you'll be able to solve the UI and layers stuff,
and maybe you'll feel compelled to watch the rest of the chapters.

Hope it helps

Yes, that's exactly the way to do it. And the best way to do that
is to make a layer mask on the upper layer, then paint black, white
or grey on the layer mask according to how transparent you want to
make it (black for transparent, white for opaque).

 Is this a case where GIMP simply makes it so difficult compared to Photoshop
 that I'd be better off buying a Windows machine and using Photoshop?

Not at all!  Layer masks make this very straightforward in GIMP.

For instance, start with step 4 of the selective colorization
tutorial: http://gimp.org/tutorials/Selective_Color/
Or try a short video tutorial I made demonstrating layer masks:

When attempting at open the GEGL dialog, Gimp crashes.
Anything else that I try works just fine (so far).
Is this known? Is there a work around?
Gimp 2.6.4 did not crash.


Downloaded and installed Gimp 2.6.7 and it appears the the GEGL issue has
been resolved.
It works, I'm happy and MANY thanks to the developers for providing this
application.

 Quoting professor for...@gimpusers.com:

  gimp-image-set-active-layer p1 ?

 You will have to manually search the list of layers for the one with
 the matching name.

 The following function will do so for a given image, returning the
 layerID (or 0 if not found).

 (define (find-layer-by-name image s)
(let* (
(layer's (vector-list (cadr (gimp-image-get-layers image

)
  (while (pair? layer's)
(if (string=? s (car (gimp-layer-get-name (car layer's
  (set! found (car layer's))
  )
(set! layer's (cdr layer's))
)
  found
  )
)
Huh???ah,  You mean:

def find_layer_by_name (image, name):
for layer in image:
if layer.name == name:
return layer
return None

(yes, this is the actual python code for it, not pseudo-code)
you just need a proper register call to have it as a gimp-plugin

Scheme was great for its time - when computers could not hold interpreters 
mroe complex than what is needed to handle scheme. Scheme may still be usefull 
-and look great - for people who already hae it flowing in their veins. But 
the truth is that for very single problems one have to go through a lot of 
work around to get to the core of it. One of the ideas of Python, as a very 
high level language is not to stay between you and the problem, as you can see 
by the snippet above.
