This discussion of saving text layer as a layer in TIFF too (not only
layered TIFF) might also be helpful reference:

Nope. I also have a second computer runs Ubuntu 8.04 (I didn't upgrade
to 8.10 yet), that every time the system tell me to upgrade I would do
it (last time was in last week). But it still uses Gimp 2.5.4 (sh??
an unstable version?).

If Ubuntu has 2.6 without a system-upgrade, I'd be glad to try. I don't
want to fight the hassle of system-upgrade in recent months. Usually a
system-upgrade means I need to get used to something a bit different, I
prefer trying that in less heavy-working days

Hi. Thanks a lot. I'll re-try both plugins you recommended after once
day my operating system (gentoo) bring me to 2.6.x. I can manually make
an upgrade to 2.6.x by changing some configuration files, but I prefer
to wait because gimp's dependencies might change the system (gtk upgrade
to 2.18). I'm not in hurry.

It will take months until gimp reaches 2.6 on Gentoo stable. I'll not
forget to re-test these things by that time. I keep a good "when xx
happen do xx" todo list management.


Thanks a lot for your solutions.

sounds interesting!
Does it work on 2.4.6? In the real world people like me are afraid of
the cutting edge and use the latest stable...

Hi. Thanks! I put the .scm file in /usr/share/gimp/2.0/scripts and try
it. When I click "OK" in clone text properties dialog I was told the

[Gimp-user] how to clone a text layer (not how to do clone on a layer)

2009-02-24 Thread zhangweiwu
Hello. Is there a feature in gimp that behave like inkscape, where a
text layer (in Inkscape an object or a group of object) can have some
clone text layers. If the source text layer changes its color, size,
text etc, the cloned layer automatically change accordingly.

In fact, I am more happy if the cloned layer only changes its text when
the source layer's text is changed.

I need this feature because I have an illustration where a word appeared
multiple times. I need to change this word from time to time. But I have
about 12 layers with the same word, doing the same text change to 12
layers from time to time look stupid. In Inkscape it would be easier.

Thanks in advance!

A more complete answer to myself in case anyone needs it too:

Tools on Linux that can do loseless cropping:

Commandline tool:

jpegcrop and jpegtrans (part of libjpeg

GUI tool:

mapivi http://mapivi.sourceforge.net


And major Linux image viewers like gthumb, eog (eye of gnome), Gwenview
all supports lossless flipping and rotating, but none declare supporting
lossless cropping (among which eog I tried and truly not having cropping
feature)

With the following googles that have corrected my stupid typos now I can
get some information about lossless cropping and answer my own question:

http://sylvana.net/jpegcrop/ offer commandline tool for cropping an image.

Fotoview is GUI tool that can do lossless cropping, written in Delphi
for Windows:

Hi. Thanks. You (and Jernej) wrote it very clear!

Can any recommend such an editor for lossless cropping & rotating,
better even lossless resizing, if possible. Cropping, rotating and
resizing are the only feature my user (not me) uses and my user wanted
to have a GUI tool. If there isn't one but only commandline tools, then
I'd see if I can re-use my tcl/tk skill to make an opensource tool for this.

Hello. I read from an article which says jpeg images can be cropped
losslessly. I searched "lossless gimp crop" on google without good
findings. Can gimp do lossless cropping? If not, what software (better
has an GUI because I am not commandline guru) on Linux can be used to do
lossless cropping?

Thanks.
