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 :owink
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 :yes , 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.

- G'MIC main project page : http://gmic.eu
- G'MIC plug-in for GIMP : http://gmic.eu/gimp.shtml
- G'MIC web service : https://gmicol.greyc.fr/
- G'MIC language tutorial pages : http://gmic.eu/tutorial/basics.shtml

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:

- [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).

Image

- [gimp] New button Change layout allows to move the preview on the right, in the dialog window.

Image

- [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).

Image

- [gimp] New filter Colors / Retro fade renders a grainy image with a only few colors from an original image.

Image

- [gimp] New filter Artistic / Posterize is another posterization filter with nice rendering options.

Image

- [gimp] New filter Patterns / Camouflage, renders (as its name suggests) a Camouflage pattern:

Image

- [gimp] New filter Black & White / Colorize [auto-fill lineart] tries to auto-fill a lineart wiith random colors.

Image

- [gimp] New filter Repair / Smooth [antialias] slightly blurs the contours of an image to add anti-alias.

Image

- [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!

Image

- [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 :)

Thanks for the head's up, David. The sharpen texture preset is fixed too as you said it would be with this release. :)

Thanks David. As always, new G'MIC releases are wonderful. I look forward to them all.

I used a font with the colorize autofill lineart. Worked very nicely. I merged the black font layer down to a white one before using the filter.

Many thanks, David.
A lot of interesting additions, my preferred one (because of my "obsession" in creating gimp filters based on a quantization) is the new POSTERIZE, at a first glance.
