Hello friends,
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.
Important note: 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 release though).
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?Quote:
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.

Changelog of the version
1.7.9, as compared to the previous stable version
1.7.8.
Enjoy !
New features:-
[core] 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).
-
[gimp] New button
Change layout allows to move the preview on the right, in the dialog window.
-
[gimp] 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).
-
[gimp] New filter
Colors / Retro fade renders a grainy image with a only few colors from an original image.
-
[gimp] New filter
Artistic / Posterize is another posterization filter with nice rendering options.
-
[gimp] New filter
Patterns / Camouflage, renders (as its name suggests) a
Camouflage pattern:
-
[gimp] New filter
Black & White / Colorize [auto-fill lineart] tries to auto-fill a lineart wiith random colors.
-
[gimp] New filter
Repair / Smooth [antialias] slightly blurs the contours of an image to add anti-alias.
-
[gimp] Main dialog parameters are now persistent when the plug-in or GIMP is closed and restarted.
Improvements / Changes:-
[core] 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() and
mp_display() 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.
-
[stdlib] 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!
-
[stdlib] Command
-compress_clut has been slightly improved, and should compress when desired compression compression quality is not fulfilled.
-
[stdlib] Command
-quiver is now implemented as a
custom command (instead of a
native one) and thus, can be updated via the regular command update mechanism.
-
[stdlib] Command
-scale_dcci2x has been recoded from scratch and is faster when multiple cores are available.
-
[stdlib] 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.
-
[stdlib] Command
-negative recoded from scratch and renamed as
-negate. An optional
base_value argument can be now specified for this command.
-
[stdlib] Commands
-rgb2xyz,
-rgb2lab,
-xyz2rgb,
-lab2rgb now accept arguments to choose the illuminant used for the conversion (either
D50 or
D65).
Bug fixes:-
[core] Fix orientation convention (correlation-like) for command
-erode with an arbitrary (non-symmetrical) mask.
-
[core] Standardize centering issue when dealing with mask of even sizes, in commands
-dilate,
-erode,
-convolve,
-correlate and
-median.
-
[core] Fix small bug to re-enable parallelism in commands
-erode,
-dilate,
-convolve and
-correlate, when a large custom mask is used.
-
[core] 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
