convert pic.xcf -flatten pic.png


That would not do what is required. It would just created an output file with 
a single layer instead of a single file with the same layers as in the 
original xcf file.


   Can PNGs have layers?

Short answer: No.

Long answer: the PNG specification allows for private format extensions, so 
applications can add all sorts of features and store them in a PNG file.
No other application is required to support those, however.

For example, Adobe/Macromedia Fireworks does this and adds vectors and layers 
to the PNG files (its native(iirc) file format). 
This tricks some users without comprehensive file format knowledge into 
regarding those as PNG standard features.

[Gimp-user] How do I prevent the paint tool from drawing outside of the selection?

[wizzythegrape]

I have a picture I'm editing with gimp. I've made a selection of part of this
picture that I'm trying to paint. When I do this, it effects pixels outside of
the boundaries of my selection. This is the first time I've seen this. Does
anyone know how to prevent/solve this?

Thanks.

The marching ants are not the limit of the selection, they are where the 
selection has a 50% value, so pixels outside the area marked by the ants 
can be partially selected. Each time you paint over them they are 
painted slightly. This isn't noticeable on the first strokes but become 
more visible after several strokes.


For what you want to do, protecting pixels with a selection isn't an 
efficient technique (problems such a the one above, halos, jagged 
edges...). You should be using Color-to-alpha (or paint in Color Erase 
mode) to remove the old color, and apply the new color in "Behind" mode.

Re: [Gimp-user] download difficulties

Hi,

Well obviously the binary you get from the official website
(http://gimp.org) is supposedly NOT infected. I mean, that's so
obvious that I feel stupid just saying it (well, after, that's also a
question of trust. But if you don't trust the people behind GIMP,
don't ever download it, whatever the download source is).
I'm not the one who makes these builds, and I don't use them (since I
make my own builds), but I would trust them if I need.

I know we already had other reports of people telling us some
antivirus software would mistakenly flag the official GIMP binary as a
virus. We cannot do anything else about this than reporting this false
positive upstream, to the antivirus editor, for them to update their
virus database. Could you tell us what is this antivirus software so
that we try and contact them?

As for you, in the meantime, your solution is to bypass the antivirus
detection (if possible. I guess there must be a checkbox or button for
this?). That's a leap of faith, but you are already doing one by
trusting some antivirus software to tell you what is right and wrong,
based on some unknown (apparently problematic, in my opinion)
algorithm or database. Or blindly trust this software, thus simply
don't use GIMP, and search for an alternative Imagine
manipulation/drawing software.
That's up to you to do what you think is right. But there are no magic
solutions other than these two possibilities (well, actually a third
one is to build yourself from source, if you know how to do so).
Have fun!

[Michael Natterer]

Hi,

GIMP 2.8.12 has been released. This is a bugfix release
in the stable 2.8 series, no new features were added.

For a complete list of changes since 2.8.10 please see the "Changes"
section below. Also see the release notes of the 2.8 series at
http://www.gimp.org/release-notes/gimp-2.8.html

Happy GIMPing,
--Mitch

  http://downloads.gimp.org/pub/gimp/v2.8/

  and from the mirrors listed at:

  http://www.gimp.org/downloads/#mirrors

  Please use the torrent, it distributes
  the download bandwidth across all mirrors:

  The checksum of the tarball is:

  47fefa240c38cfb1016b57ad6324378d  gimp-2.8.12.tar.bz2


Overview of Changes from GIMP 2.8.10 to GIMP 2.8.12
===

Core:

 - OSX: Fix migration code for old GIMP directories
 - Fix brush sizes when used from plug-ins
 - Windows: Allow to Explorer-open files with UTF-8 characters in the
filename
 - Make XCF loading more robust against broken files


GUI:

 - Make sure the widget direction matches the GUI language
 - Remove the option to disable the warning when closing a modified
image
 - Fix canvas overlay widgets (like the text options) for tablets
 - Make DND work between images in one dockable


Libgimp:

 - Make gimp_image_get_name() return the string used for the image title


Plug-ins:

 - Make script-fu-server more secure by listening to 127.0.0.1 by
   default and add a warning about changing that IP. This breaks the
   procedure's API, but for security reasons.
 - Bring back proper script-fu translations


General:

 - Massively clean up and fix the OSX build and bundle
 - Add Jenkins tutorial
 - Documentation updates
 - Bug fixes
 - Translation updates
