[Gimp-user] Under Water Effect Tutorial

2009-03-22 Thread David M.
Here's what I have so far, feel free to comment of give suggestions oh how to
make it better. I tried to make it Very basic so anyone could do it. Btw I
wanted to add it to the tutorials page But couldn't figure out how.

Let's begin:
1. Find any image, any size, I will use a fish!
Ok so I have only one layer the fish, it's some coral in the Background, but
it's not blue enough!

2. Adding blue.
Sure you could just colorize or use a screen but let's use a lava layer;
Filters>render>lava
For Gradient select Horizon2, you can leave the other settings alone.

3. Using the blue as a tint, now I know I said I wasn't going to use screen
mode, but I lied, go ahead and click on the "lava layer" and in the box under
the word "layers" is "mode" set mode to screen using the dropdown box.
Now it looks kind of funny, so set opacity to something around 30.

4. Merge
Right click on the "lava layer" and select "merge down"
Now the two images become one

5. Waves
Go to filter>animation>rippling
And set the strength to 1.0
And edge method to smear
Ad set frames to what ever you want
Click ok
Wait a bit for it to finish.
Then you should have as many layers as you set the frames to.

6. Prievw
To watch your animation
Go to filters>animation>playback
And click Play! You can close the play back window when you're ready to
save.

7. Saving, well you could save it as a Gimp Image, but if you want to put it
on the web or email it to a non GIMPst
You need to export it to ether an AVI or An animated Gif.

You may need a plug-in for exporting to AVI, but if you want to save it as an
animated gif,
File>save as
And click "select by file type" and find gif image
A .gif should appear at the end of your file name;
If not put one there.

Make sure you tell it to "SAVE AS ANAMATION"
And Don't Select Convert to grayscale

And set time between frame to 10 milliseconds

And use delay entered for all frames.
And check the interlaced box 

Now open it in IE or something, and BAM! Moving water.

Try out Hugin, that's a different program, but highly specialized on stitching

Thanks for the quick reply,

However, I realized that 'gimp-levels-stretch' only takes a filename
as a parameter, so I removed the additional ones:

'radius, amount, threshold'

from the example script (definition & function call) and from the
bash command.


So something else must be wrong.

It has problems with menu mnemonics, as you found out yourself. That's
why its use is discouraged by the GTK+ developers. GIMP is probably the
only application that still allows to enable it.

That is indeed a Unicode char code. Your desktop font lacks this
important character and fontconfig does not seem able to locate a
fallback font for it. There's a bug report against Pango about this. If
you want to help fixing this, please check the bug-tracker.

if it has to be - in _my_ opinion, the other method is much 
easier to use for me.

E.g. I try to set Alt-R for 
rightclickonimage-Image-Transform-RotateClockwise90°.

With the editor, I search for "rotate". Now there are two 
Rotate 90° clockwise commands (plus some other rotate 
commands). Which is the correct one? The  image one or the 
drawable one?

With the menu method, I simply open the menu item I want and 
press the key. And I know that I have set the shortcut to 
the correct command ...

Btw, in the zoom dropdown box at the bottom of the image 
window, between the value and the % character, there is a 
box with tiny "2005" or "2009" (too tiny to decide which of 
the two). As the dropdown is only wide enough for "1600%", 
the full "2005" and the percent sign are only visible after 
scrolling horizontally in the opened dropdown ...

Could this be a unicode char code? 2005 would be a 
"Four-per-em-Space", 2009 a "thin space" (fifth of an em).

[Gimp-user] 'gimp-levels-stretch' in batch mode

2009-03-22 Thread wwaser
Hi,

I have used ImageMagick for batch mode treatment of images but
would (have to) use gimp for certain functions.

Being completely new to the gimp script-fu, I copied an example
from the intertubes

-
(define (batch-unsharp-mask pattern
radius
amount
threshold)
  (let* ((filelist (cadr (file-glob pattern 1
(while (not (null? filelist))
   (let* ((filename (car filelist))
  (image (car (gimp-file-load RUN-NONINTERACTIVE
  filename filename)))
  (drawable (car (gimp-image-get-active-layer image
 (plug-in-unsharp-mask RUN-NONINTERACTIVE
   image drawable radius amount threshold)
 (gimp-file-save RUN-NONINTERACTIVE
 image drawable filename filename)
 (gimp-image-delete image))
   (set! filelist (cdr filelist)
-

saved it as

~/.gimp-2.6/scripts/batch-unsharp-mask.scm

and run it with

gimp -i -b '(batch-unsharp-mask "*.jpg" 5.0 0.5 0)' -b '(gimp-quit 0)'

It worked.

I also found the function 'gimp-levels-stretch' in the Script-Fu
Procedure Browser and tried to adapt the example script:

-
(define (stretch-levels pattern)
  (let* ((filelist (cadr (file-glob pattern 1
(while (not (null? filelist))
   (let* ((filename (car filelist))
  (image (car (gimp-file-load RUN-NONINTERACTIVE
  filename filename)))
  (drawable (car (gimp-image-get-active-layer image
 (gimp-levels-stretch RUN-NONINTERACTIVE
  image drawable)
 (gimp-file-save RUN-NONINTERACTIVE
 image drawable filename filename)
 (gimp-image-delete image))
   (set! filelist (cdr filelist)
-

saved as 'stretch-levels.scm in ~/.gimp-2.6/scripts/ and run as

gimp -i -b '(stretch-levels "*.jpg")' -b '(gimp-quit 0)'

Does not work and prints the error message:

'batch command experienced an execution error'


I would be very much obliged for any help getting the 'gimp-levels-stretch' 
function run in batch mode.
Any pointers to online instructions etc. would be appreciated.

Thanks, W.

[Gimp-user] small problem assigning keyboard shortcuts

2009-03-22 Thread Andreas Waechter
Hi,

I set "Use dynamic keyboard shortcuts", so I can assign 
shortcuts "on the fly" by moving the mouse pointer onto a 
menu item and type whatever shortcut I want.

This works wonderfully in almost all cases.

For a very long time I always assigned some keys for the 
zoom levels:
1 for 1:1, 2 for 2:1, 4 for 4:1, 8 for 8 for 8:1, 6 for 16:1
and
Ctrl-2 for 1:2, Ctrl-4 for 1:4, Ctrl-8 for 1:8, Ctrl-6 for 1:16

I still can assign the Ctrl-Combinations for the 1:2 to 1:16 
zoom levels. But I can't assign 2, 4, 8 or 6 to the 
enlarging zoom levels 2:1 to 16:1.
When I try e.g. placing the mouse over the 16:1 menu item 
and press 6, instead of assigning the shortcut 6 to that 
item, the 1:16 menu item gets selected.
Similar for the other zoom levels.

This happens in 2.6.3.

I just checked, ok, there is 2.6.6 available, I will give 
that a try.

Still the same in 2.6.6.

So the question remains: why can't I assign the shortcuts 2, 
4, 6, 8 to the view-zoom-commands 2:1, 4:1, 16:1, 8:1?

Thanks in advance
Andreas

Not certain on this board how to truncate quoted text, so, I'll just leave it
all in.  I must have missed Martin's reply on changing the units on my ruler,
because I cannot find it.  If you could guide me or reiterate, I would be most
appreciative.  The bit about turning off dot for dot in the view menu did not
help my rulers.  There must be something in addition to that which I am
missing.

Martin already answered your questions about units, so I'll just
address this part. I've done business cards and labels in gimp
(http://shallowsky.com/software/gimplabels/) and they can line up
if you get the distances right.

You have to make sure you have an image that matches the size of
your paper, and get the offsets right, of course.  I've tried to do 
labels where I made the image size match up to the outer edges of
the outer labels, then set the offsets in gutenprint, and it was
frustrating and never worked right.

I've only printed with gutenprint, where it's easy to see when
you're printing a full page with zero margins on any corner. I
couldn't get the same amount of control through gtkprint, though
it's gotten a *lot* better in the last few releases and maybe
it would work now. Another option, if you have trouble with gtkprint
not lining up, is to print to postscript or PDF, preview it to
make sure the page size and margins are what you expect, then
print that from another app.

Also, my inkjet printer (YMMV) varies quite a lot from page to page,
so even if I create a perfect template at the perfect size, printed
labels may not register exactly with the label sheet. So you
need to make sure any text doesn't go all the way out to the edges
of the label, and that any background is wide enough to spill over
the edges quite a bit. Drawing a neat box just inside the edges is
right out, unfortunately. Maybe some printers are better at that.

That's exactly the right attitude. There are lots of apps designed
for printing labels and business cards, but I like having the option
of making them in GIMP because it gives me the option of printing at
high quality and high resolution. I always keep in mind that this
isn't really what gimp is for, so if I have to do a little extra
fiddling compared to glabels, it's my choice.

Printing works perfectly for me on Linux. If there are issues, then I'd
like to know about them. Most likely it will turn out that the issue is
not in GIMP, but in your printer driver. But if there are issues in the
GIMP Print plug-in, or in the GtkPrint framework, then it is important
that these are reported. You might even get your hands dirty yourself
and look at the source code and try to fix them. After all this is Free
Software and we give you the source code exactly for this purpose.

Had the same problem but never tried to solve it since I mostly use Linux.

But Gimp on all OSs does have issues with printing and that is Gimp's
achilles heal.

You might want to download and install Gutenprint and use the gutenprint
drivers.  That may work but there may be other issues with paper sizes there
also.  I am not sure but it is at least something else to try.

[Gimp-user] Cannot print from Gimp

I am running Gimp 2.6.4 from Windows XP.  If I try to print a 4 x 6 photo,
setup selections to not stick for paper size/orientation.  I select 4 x 6 in
my Canon i960's setup dialog, and the preview window shows that 4 x 6 paper is
selected.  I can scale the photo to fit 4 x 6, but, when I click the button to
actually print the picture, my Canon's preview window shows a 4 x 6 image in
the upper left hand corner of an 8.5 x 11 page preview.  If I press the button
to complete the print job, the photo will "fall-off" the physical media (it's
not printed in the proper position).

My work around for now is to use another application for printing (CS4,
Sony's Image Data Converter, etc.).

Is this a bug or some other problem?

Hi

The unit of the rulers is the same as the unit in the bottom of the
image window, in the left part of the statusbar.

The unit you used to display the image is not saved to the file, so when
you open the file on another computer (or the same computer) the unit of
the window will default to pixels. One could argue that the unit used to
display the file should be saved, but it is not trivial to solve since
one image can be shown using different units in different image windows.

In any case, to show the rulers in inches on your machine, just change
the unit in the statusbar to inches.

I love the Gimp.  However, yesterday, on my daughter's new Vista laptop, I
used the rulers to pull guide lines to a blank page to replicate an Avery
business card template.  Managed to create the first card, then, copy/paste it
as appropriate to populate the template.  My printer is in the basement, so,
rather than carry her laptop downstairs, load a new printer driver onto it,
just to print her cards, I had her email me the xcf file which I opened in
GIMP 2.6 on my machine.  We constructed the template with the rulers showing
inches, but on my machine, they are showing something else (I don't know
what).  

I followed your suggestion and turned off dot for dot, but no change in the
rulers. I can bring up the Preferences-Units "window", and there are listed a
selection of units, all of which are checked.  Unchecking these or rechecking
them seem to have no effect on the ruler display.  Can you explain to me what
I am missing.

Also, although I was meticulous in measuring for and laying out the template,
my cards did not line up with the pre-cut forms that we had purchased.

I had spent the better part of two hours on this little project, and we were
running out of time, so, I opened Adobe InDesign with which I am very familiar
and completed the project from scratch in about 15 minutes.

That is not to knock Gimp.  I knew from the start that Gimping the project
was the long way around - but I wanted the experience.  I feel I was almost
there, but would appreciate further help on this ruler business.  Without
units in inches on the ruler, I was consigned to start from scratch in Gimp,
but, even if I had had time, the units showing were not familiar to me (very
large numbers, 1500, etc.).

Sorry to be lengthy, and thanks in advance for any advice.

(my first forum post!)

Thanks. That solved my problem. -- Catherine
