I'm happy to announce the release of a new version (numbered 1.7.9
) of the G'MIC image processing framework
(including of course, the plug-in for GIMP).
As always, I encourage upgrading to this new version as soon as possible
This version should be backward-compatible
with the previous one (1.7.8
), meaning that all added filters that do not use new core features of version 1.7.9
should work also with version .7.8
This new version 1.7.9
is the last of the 1.7.x
serie, so I expect it to be a long-term release
. We have planed a lot of new cool features for next version 1.8.0
, but this will require a lot of work before we can release (this will be a major
Now, we have heavy work on our way, so I hope you'll enjoy this release ! I'll try to give you info about the on-going work done on G'MIC.
Thanks again, GIMPchat members for all your tests and feedbacks on the plug-in (dinasset, Mahvin, lylejk, iarga, gnutux, MareroQ, spacepenguin, paulmat, rich2005
, and all the others I forgot !). After all those years, GIMPChat is still the place to be
, thanks !What is G'MIC?
G'MIC is a full-featured open-source framework for image processing. It provides several different user interfaces to convert/manipulate/filter/visualize generic image datasets, ranging from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images, thus including 2d color images.

The following is the full Changelog
of the version 1.7.9
, as compared to the previous stable version 1.7.8
Enjoy !New features:
New (native) command -screen
grabs a screenshot (optionally with specified coordinates), and inserts it at the end of the image list (looks like it does not work on Mac OSX)
New button Change layout
allows to move the preview on the right, in the dialog window.
New filter Artistic / Highlight bloom
enhances photographies by adding details and contrast. It is inspired by [link=https://pixls.us/articles/highlight-bloom-and-photoillustration-look/]this tutorial[/link] (but does not follow it strictly).
New filter Colors / Retro fade
renders a grainy image with a only few colors from an original image.
New filter Artistic / Posterize
is another posterization filter with nice rendering options.
New filter Patterns / Camouflage
, renders (as its name suggests) a Camouflage
New filter Black & White / Colorize [auto-fill lineart]
tries to auto-fill a lineart wiith random colors.
New filter Repair / Smooth [antialias]
slightly blurs the contours of an image to add anti-alias.
Main dialog parameters are now persistent when the plug-in or GIMP is closed and restarted.Improvements / Changes:
A few improvements in the embedded math parser:
- New function xor(a,b)
to compute bitwise exclusive or.
- New function pseudoinv(A,_nb_colsA)
computes the Moore-Penrose pseudo-invert of specified matrix A
- New function svd(A,_nb_colsA)
computes the SVD of specified matrix A
- New function breakpoint()
introduces a computation breakpoint in complex expressions with loops.
- Function mp_print()
only print a limited number of vector components on the console, if the vector to print/display is large.
- Expression compiler has now a cache memory for constants
so that specifying the same constant value twice (or more) in an expression does not duplicate it in memory.
- Multiplication operator can be now used to write matrix*vector
multiplication, when size(matrix)==size(vector)^2
- Initialization of vector variables has been optimized: memory copy is avoided when possible.
- Vector with const size (given by an expression Expr
can be now defined as vectorExpr(value0,...)
, e.g. const N = w#0*h#0; X = vectorN(0)
- Function normP()
can be invoked with P
being a constant. If P
is omitted the L2 norm is returned.
- Optimization of the math_lib
functions thanks to newly added function draw_scanline()
- Adding a space character before a (
(for a function call) or a [
(value accessor) is now possible.
- Bug fix in the function sum()
which was counting twice the first argument.
Add 10 new HaldCLUTs that define new color mapping. Those CLUTs are provided by [link=http://www.digicrea.be/picturefx-v2-0/]Marc Roovers[/link] on his web page, as a part of the PictureFX
pack. Thanks Marc!
has been slightly improved, and should compress when desired compression compression quality is not fulfilled.
is now implemented as a custom
command (instead of a native
one) and thus, can be updated via the regular command update mechanism.
has been recoded from scratch and is faster when multiple cores are available.
Some existing commands have been renamed:
- Command -input_sample
(eq. to -is
), renamed to -sample
(eq. to -sp
- Command -input_clut
, renamed to -clut
- Command -input_string
, renamed to -string
recoded from scratch and renamed as -negate
. An optional base_value
argument can be now specified for this command.
now accept arguments to choose the illuminant used for the conversion (either D50
Fix orientation convention (correlation-like) for command -erode
with an arbitrary (non-symmetrical) mask.
Standardize centering issue when dealing with mask of even sizes, in commands -dilate
Fix small bug to re-enable parallelism in commands -erode
, when a large custom mask is used.
Fix small bug and improve precision of command -resize
when used with linear, cubic and lanczos interpolations.
- And as always, many fixes of minor bugs
