  Last summer I made an effort to explore various watermark techniques
which were doable using The GIMP.

The most fascinating method I found was explained in one particular web
tutorial which I am sure I bookmarked, saved to my hard drive, or both
and will simply need to relocate in order to point you to it if you'd
like to pursue it.

The basic idea is to create and save in your ".gimp-2.x" directory a
tiled pattern file (i.e. "filename.pat") which contains the text of your
copyright notice and/or anything else you want your watermark to
contain.  I believe the text was opaque and white on a transparent
background.

You then load into The GIMP an image you wish to watermark.  Add a
transparent layer above it and "flood fill" that layer with your white
watermark pattern.

Then you perform a couple of funky image tricks on it before turning the
opacity of the watermark layer down to almost but not quite zero.  At
that point it becomes virtually invisible and most people will never
know it's there.

Then to reveal the watermark should you ever need to prove the image is
yours in a court of law or whatever...  Just load into The GIMP both
your unwatermarked original and the watermarked copy as two separate layers.

Then change the layer mode of the upper layer to "Grain Extract" or
whatever it is - I cannot right now remember.  The parts which are
common to both images will be opaque gray but the parts which are
different (i.e. the watermark itself) will become clearly visible.

This technique survives pretty much every known technique intended to
defeat watermarking.  I was very impressed with the idea of it.

Re: [Gimp-user] import vs open

2013-02-20 Thread s.kortenweg

From the start of GIMP 2.8 there are rumors about Save vs. Export.
It is a change with the past, but that has happened more times by 
changing versions.
The first version of the GIMP that i started (i believe 1.2) came up 
with a single toolbox and nothing more.

 And i survived all the changes that came after that.
To make the changes more visible for the users is it possible to add to 
the various Save options

in the File Menu that this will happen in XCF format?
For overwriting the original file there is already the option Overwrite 
..

For saving with another name the export option can be used.
I hope that this suggestion stops the endless discussion about this change.

In open source, developers and users should be on the same side. Many times,
there is some flow between the two groups. With commercial software, the
relationship is explicitly one of commerce and market dynamics. With open
source, when functional at least, the whole community is important.

So, while you certainly get a number of obnoxious people with an
over-wrought sense of entitlement, not all feedback along these lines is
that way. I share what I think not because I can't work around it, but
because the new enforced workflow is more difficult for me and I think
more difficult for others, to the detriment of the software as a whole. I
don't presume any right to demand anything, but designers and developers who
don't listen to their engaged, active, and concerned users are missing
something valuable. If the same thing keeps coming up over and over again to
the point where everyone is tired of it and very frustrated, maybe it's time
to step back and rethink a little bit.

Someone a while ago had the suggestion of building sidecar files with the
entire undo history of an image. As storage space continues to increase,
that sounds like a very promising path providing best of all worlds.

I mean, sure, the developers are perfectly fine in saying no, we're gonna
do it this way, but it's also short-sighted to say and stop giving
feedback. It seems better to say We did it this way for reasons x, y, and
z, but we recognize that what you're asking isn't like the broken spacebar
comic. You have options a and b now, and we're thinking about some even
better approaches in the future.

That's not a sign of weakness.



I completely agree with your comment

Part of the reason for this change, is to align the current UI with
such capabilities that GIMP eventually will gain as part of the
ongoing GEGL integration effort. As already mentioned many times in
this thread and through the last decade; GIMP is moving towards a
non-destructive editing mindset – interactions designers/architects
involved, core developers and well informed users that closely have
been following the development over the last decade are aware of this.

When such changes have landed in a stable release; there has been a
quite long period of feedback from the users that follow development
more closely than the users that only use stable versions of GIMP.
This is also the reason that core GIMP contributors consider this
discussion to already be done and dealt with before it flared up and
trolls are keeping it artificially alive. The self selected beta
testers that are willing to use the development version and work out
problems during active development have a larger influence on
decisions. These are also the users it makes most sense for the
developers to spend their volunteered time communicating with – since
these users directly contribute to finding bugs and potential problems
early.

That doesn't appear to have been the case here. I brought this up during the
2.7.x development series, and was told that it had already been decided.

 I would say: okay, cool. But that's not what I've been seeing. It's largely
 along the lines of you just don't understand that your way causes data
 loss. 

Well.. that is a part of it, but it really stops short of the entire point, 
which is not you just don't understand that your way causes data loss, but 
more like there are many things in GIMP currently that cause data loss.  We
are working over the next few releases to change this model such that data 
loss will never be part of the expected workflow.  The change to the save vs.
export file handling is just one step in many toward this goal.   We won't 
totally stop you from losing data if you really want to, but we will keep 
anyone from doing it accidental.  

Also, please remember that big part of the tone of many around here is that
it keeps coming up and in some cases, the same people continually repeat their
arguments and some who are just plain rude about it(calling someone working
for free on a program you use stupid is generally not a way to endear them 
to your opinion..not saying *you* have but a few people have said such 
things and even far worse)  I don't know if you have kids or not, but it's 
kind of like being on a road trip and the kid saying are we there yet dad?
The first few times(hopefully), you are nice, but after the kid asks for the
50th time, you feel like breaking something.


 And Overwrite is pretty close, but it doesn't mark images as clean, so I 
 get confused about what I've saved already. 

But see, that's because it's not supposed to.  Again, you have to remember 
that as of 2.8, any image pulled into Gimp is NO LONGER a .jpeg or .png or 
whatever, it's a Gimp image(xcf).  You can verify this by looking at the 
filename in the titlebar which has the (imported) modifier beside it.  
This shows up for non GIMP file formats and is your cue that you are working
on a non native file format(also notice that it goes away once you save to a 
Gimp file format, as well as the overwrite flag.) This is the whole point 
in that going forward, it is expected that you work in a non destructive 
methodology.  Another thing to remember is that you are using a plugin to
try to get around a behavior that was built in and it's never going to be 
able to override all of the default functionality(yet another reason I 
suggest people just bite the bullet and change their thought processes).

Anyway...

2013-02-20 Thread Dominik Tabisz
I apologise that my last message appear as writen by s.kortenweg.
Next time I'll pay more attention to what is going to be send, before
i press send button.
This bad example from Corel is my experience and i don't wish to speak
for anyone else.

Dominik Tabisz

2013/2/21, Dominik Tabisz d.kup...@gmail.com:
 All the arguments about encouraging/forcing users to non destructive
 workflow are reasonable, but there is one tiny problem. I've
 encountered it while cooperating with professional users of
 CorelDraw (design studios, marketing companies etc.)

 Corel can understand bunch of vector-based fileformats. It can import
 them, it can write into them. So in theory i could prepare image in
 *.eps or *.svg and it can be later processed in Corel.
 In fact any images that was not in native CorelDraw fileformat was
 rejected. (Even images from Adobe Illustrator !)

 Reason was simple: Corel open only it's native files (*.cdr). You can
 launch Corel and later import *.ai, *.svg, *.ps but You can not just
 navigate to such file and double click it to edit. You can't open them
 from command line too.
 This mean that professional corel users were forced to THINK ...
 they just choose to reject Your graphics.


 We can improve programs, we can create better images but we're unable
 to change peoples (un)thinking habbits. Please imagine what harm to
 trade and workflow can arise from proposed improvement of open/import
 behaviour.

 If You really believe that this change is necessary, there should be
 way of avoiding disaster that happened to Proffesional Corel Users.

 Let me give some proposition:
 1)Gimp always open/import any type of file, it can understand. No
 matter if we ask program to do so from it's menu, command line or just
 click file in file commander.
 2) After Gomp start and examine the file there are two possibilities:
 a) file is an *.xcf so Gimp just open it.
 b) file is not *.xcf - Gimp show the message and ask for permission
 to import it.

 If proposed change don't stop launching Gimp and opening/importing any
 file just by selecting it in a file commander, than You can hope it
 won't do so much harm to the bussines as Corel behaviour did.
 All differences would be one click more and Gimp remain universal image
 editor.

 I hope that we're not going to redefine meaning of word
 professional. Corel disaster shows that new meaning of this word is:
 someone who have ability to reject Your work. Don't let such
 redefinition happen in Free Software ecosystem.
