[Gimp-user] Running Gimp 2.4 and older versions of Gimp (2.217)

2007-10-25 Thread D.Jones (aka) Capnhud
I have alot of plugins that I use in the older version of The Gimp and do not 
want to
lose them. I was wondering can I have both the new and old version of The Gimp 
installed
on Windows XP without having a conflict.  Or do I need to install Gimp 2.4 
somewhere else
other than C:\Program Files

[Gimp-user] Can I translate a page of gimp.org?

2007-10-25 Thread Choi, Ji-Hui
Hi, list

I want to translate the introduce page of gimp 2.4.0 in gimp.org
this page, http://gimp.org/release-notes/gimp-2.4.html
who does maintain this page?

BTW, I want to translate and post on my site, http://gimp.kr
my site is not a commercial site. just a tutorial site for gimp.

Can I do this?


Greetings.

Ji-Hui,

I'm also interested in the translation. What can I do for you?
Of course, I use Gimp for editing and viewing graphic images..

And now I am sending mail with Mutt instead of Evolution because 
I am upgrading GNOME to 2.20 version by hard compiling now.
That's why now I cannot use a GUI MUA like Evolution.

FYI; My current desktop runs GNOME on FreeBSD. 

I'll wait for your letter ;;

[Gimp-user] colour to black and white

2007-10-25 Thread norman
I would like to be able to produce a black and white negative image from
an ordinary colour image. The effect I would like to produce would be to
imitate what one would get if you took a colour, positive transparency
and made a contact print on to either orthographic or lithographic film.
Thus, blue would be black and red would be clear and transparent. Have
you any suggestions how to approach this using the Gimp, please.

Colors-Components-Decompose (elseqwhee if you are on gimp 2.2, b ut 
still decompose)

and pick only the Hue  channel.

You cna tehn use colors-curves, or colors--levels to equate your 
previous blue to black and your previous red to white.

I'm lazy, so desaturating on luminosity works well enough for
me. If I wanted to alter the colours, I'd put the image through
a colour-map first.

For example, I have a shot of an evolutionary sequence which
runs from a little ape-like fellow through Magnon to a normal
human standing tall, who then picks up a rake  starts to bend
down again as a result,  so on through a jackhammer until he's
sitting worshipfully at a computer keyboard.

I boosted the blue (Colours, Curves) a fair bit, then desaturated
that for a slightly sharper-looking monochrome image.

Not sure why artists do this, but the modern-man figures were
all Caucasian,  boosting the blue up fairly strongly, emphasised
the contrast between these fellows  everyone else up to Mr
Cro-Magnon, inclusive, who all had fairly mid-range colours..

Cheers; Leon

Thank you for that. I cannot see a channel labelled as Hue, perhaps I
am looking in the wrong place. I am using Gimp 2.4.0-rc3.

Would it then be possible to actually have the white areas transparent?

Re: [Gimp-user] colour to black and white

2007-10-25 Thread norman

 snip 

 Decompose you image to RGB components.
 In the new image, hide the red and green layers.
 Add a layermask to the blue layer, initialized to a Grayscale copy of  
 the layer.
 Fill the blue layer with black.
 
 OPTIONAL: Most orthochromatic film would respond to some extent to  
 green, so repeat the last two steps on the green layer, make it  
 visible, and set its opacity to a relatively low value (0-30%).

This is very interesting and to a learner like me not too complicated.
Perhaps I did not do it quite right but I have what appears to be an
overlay of small black and white squares. How do I get rid of that?
 
 This method is a bit crude, but should provide something not entirely  
 unsuitable. A more accurate approach would probably entail applying  
 appropriate curves to the different color channels.

Crude or not it looks very effective and a good starting point. Thank
you.

Norman

2007-10-25 Thread saulgoode
There should be no white in the resulting image. When you decompose to  
RGB (Colors-Components-Decompose), you end up with a grayscale  
image with three layers -- one each for the red, green, and blue  
components.

When you add the layermasks, you are basically making the the black  
parts of the layers transparent and the white parts opaque. When you  
fill the layer with black, you convert the opaque parts to black.

The end result is a layer consisting of black parts and transparent  
parts (your lithographic negative). There should be no white in your  
image.

Perhaps you could describe the steps you are taking which produced an  
overlay of white and black squares?

Oops, I just realized that what you describe may be attributed to the  
fact that GIMP will display a dark gray/light gray checkerboard to  
indicate transparent regions. Perhaps you have created your lithograph  
correctly but misinterpreted this representation of transparency.

You might try creating a new white layer and placing it at the bottom  
of the layerstack to show the regions where your image is transparent.

Re: [Gimp-user] Pngs, jpgs, tifs, etc.,

2007-10-25 Thread Peter Russell




(Sorry I just realised I sent this directly to you by accident here is a resend to the list.)
You should really do work in "xcf" which is Gimp's native image
format. (you can also save a full copy of your work in xcf and go for a
walk or something then reload and continue from where you left off).
When you have finished the image you can then save it in any image
format you want that is supported by the Gimp (and there are many).
Probably jpg is the most favoured, png is lossless and supports
transparency. Depending on your work you may want to use gif. There are
many other's to choose from.Regards Pete-Original Message-From: [EMAIL PROTECTED]Sent: Thu, 25 Oct 2007 00:03:49 -0400To: [EMAIL PROTECTED]Subject: Re: [Gimp-user] Pngs, jpgs, tifs, etc.,this is probably going to sound like a really weird solution to a problem but it has worked for me over the years. i often wander off the beaten path though so that tendency may work for someone else too. if i have an image that isn't working in the computer, i make the best possible print i can of it. then i may go into that print with other (live) media and punch it up that way. then i scan the print into the computer and make a new image from the scan in a file format i like and with a resolution that is better than what i had. then i use the image program to adjust the image until it takes shape as something i want to keep. usually there is a good chunk of the original image which still remains so all has not been lost. 
i am simply not used to using the native format of the GIMP program. for awhile i used to use the native format for photoshop, which was psd. then i discovered that a whole bunch of other programs i had would not show a thumbnail of a psd. yet they would all show it of a tif. (this was while i was using windows as my OS) so i started using tif and was happy with using it. there is some relief in knowing that every single program you have on your computer will be able to show the image in the tif format. this is also true of the jpg, the png and the gif.

In this case - the "problem JPEG" - re-saving as JPEG would onlyproduce more of the same artifacts that were causing grief to theengraver.As a designer I frequently deal with this scenario: "Hi, we need X
printed on Y and it needs to be Z feet tall.All I have is this(crappy) JPEG (or fax, doc, ppt, etc)". I try this:1. is it a corporation?is the logo on brandsoftheworld.com
?2. do they have vector artwork on their web page (hidden in a PDF, etc)?3. is it just a font?can "what the font" figure it out?4. can I salvage it in GIMP (or PS) or Inkscape?5. redo it :(
Regardless of the solution, the format chosen to save my work in is upto me - just because I was _given_ a JPEG, there's no reason for me to_save_ it as JPEG later.Sorry, this turned into a bit of a rantI guess all I was trying
to say is that you're not locked into saving as a JPEG just becausethat's all the client has to offer :)Chris___Gimp-user mailing list
