I have looked but this does not answer my specific question,
unfortunately. I cannot believe my question was so obscure that no one
has been able to answer it yet. Perhaps it is too simple and I am
missing the point somewhere.

Yes, maybe you should rephrase it, I'd thought that you wanted to know methods 
to have more control than with one of the straightforward methods:
 - Image->Mode->Grayscale (the whole image will be grayscale, you'd have to 
change back to RGB mode to edit with colours again)
 - Colors->Desaturate, which has three predefined modes since GIMP 2.4

If that's not what you want, maybe you should ask again in a different way ;-)

There are no such things as adjustment layers in GIMP, but in one of the 
future versions, much more powerful tools will be available to allow 
non-destructive editing.  You can do pretty much of what's done there though 
in different ways as mentioned on the page that Tim gave.  As to why the BG 
copy 2 layer in your page is b&w, I best quote that page itself:

"the top layer (Background copy) shows where we did a simple 'remove colour' 
and have de-selected the 'eye' so as to hide this layer."

The coloured seem to be effectively desaturated with one of the adjustment 
layers.

Thank you very much indeed. Now I can forget all about the approach I
thought I would look at and concentrate on those ways I know best - the
methods suggested and demonstrated by Ralph Steinort.

[Gimp-user] How I save the settings of a tool?

2008-04-12 Thread Lap1994
I am learning Pixel Art. And if you do not know what is, you have the idea  
that iis about pixels. Well, I draw images at level of pixel. Then I have  
to draw with pixels, and erase with hard edge.

Everytime Gimp starts, I have to set the settings again. Well, can I save  
the settings to stop this time waste?

"Rolf" please! ;-)

I think this is basically the same thing that you can do with the
channel mixer. 

In the top adjustment layer they do a "crude" desaturation by simply
removing it. You can do that in Gimp by adding a layer filled with black
and setting the mode to "saturation".

I don't get what the lower layer does. I'll ask a friend an d report
back. Perhaps there is something interesting in it.

Yes. Preferences -> Tool options
provides the option to 'save tool options on exit'.

Nothing interesting. 

I just talked to John Arnold from http://photowalkthrough.com/ (worth to
look into even for Gimp users). He told me that this is an old method
and has less control than the channel mixer. 

The lower layer just rotates the colours. That leads to a different
luminosity and so to different monochrome output.

Hi Lap (if this is your name),

quite interesting: This is what I did back in the 90s on a Atari ST.
For the hires monochrome screen (600x400 pixels) there was no 
greyscales. And back then I was very into devising my own system fonts, 
my own desktop icons etc. Hence everything was done in a bitmap editor.

But why would one act thus nowadays? Is it just a "hobby" like ascii 
art? Is it a "serious" class at some college? Is the only "propper" way 
of editing to sett single pixels by means of a mouse cursor?

Maybe mtpaint is closer to your requirements?

Regards
Ralf

For some people it is

> Is it a "serious" class at some college?
No. However, pixel art is used for commercial 2d games, like those you
can find on the Gameboy Advance or on mobile phones. For example, so
much pixel art was used in the new Contra game that there are at least
12 different pixel artists who made graphics for it.

You can get an idea of what pixel art is wanted for from here:
http://www.wayofthepixel.net/pixelation/index.php?PHPSESSID=873c18254f730e0f1596c2ec94208841&board=6.0

It is the 'pixelation' forum's 'employment' subforum.

> Is the only "propper" way of editing to sett single pixels by means of a 
> mouse cursor?

If the image you are editing is small: Definitely!
It depends on the significance of the individual pixel in the work.
typically pixel art might be made in any resolution up to 512x384
 (where the significance of an individual pixel is 1 in (512 * 384 ==
196608 pixels))

Some large pixel art:

Personally I tried mtpaint, and while it's pretty effective, it lacks
polish and some key features (eg. moving to next/prev color) for my
purposes; which is why I use GIMP still.

[Gimp-user] Preview window

2008-04-12 Thread Lap1994
Gimp have a preview window that appears when you zoom the image? I know  
MSPaint have.
With this you see what your small brush do in the real size image when you  
are in a zoom of 2x or 4x
