David_Tschumperle · September 8, 2023, 4:31pm

This is the changelog for the release of the 3.4.0 version of the G’MIC software, released on 2024/06/15.

It lists all new features and changes done since the previous version 3.3.0.

What is G’MIC?

G’MIC (GREYC’s Magic for Image Computing) 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.

What’s new in version 3.4.0?

New features:

Version 3.4.0:

[source-340] Add CONTRIBUTING.md file that explains how to contribute to the project.

Version 3.3.6:

[gmic-qt-336] New filter Colors / Mixer [Generic] allows to apply linear and nonlinear transformations on color channels, for a wide range of different colorspaces.

[gmic-qt-336] New filter Deformations / Distort [RBF].

[gmic-qt-336] New button Randomize Parameters (dice icon) in the G’MIC-Qt plug-in, that randomizes parameters for filters that support it.

[gmic-qt-336] New filter Rendering / Spline Spirograph, offers a range of settings to create intriguing, colorful textures, from spirograph-like process.

[gmic-qt-336] New filter Rendering / Underwoods, by @prawnsushi .

[gmic-qt-336] New filter Degradations / Blur [Motion] simulates motion blur on images, with user-defined trajectories.

[gmic-qt-336] New filter Rendering / Color Wheel, by Claude Lion.

[stdlib-336] New command warp_seamless warps selected images by specified displacement field, using seamless blending.

Version 3.3.5:

[gmic-qt-335] New filter Layers / Spatial Blend Multi-Layers takes a bunch of input layers and blend them all spatially, according to a user-defined orientation. Useful to quickly create intriguing images from timelaps frames !

[gmic-qt-335] New filter Artistic / Stringify renders images with colored lines.

[gmic-qt-335] New filter category Map Projection/, with 14 new filters to project equirectangular maps using various projection methods. This is a very nice contribution from Kristian Järventaus, a member of the Cartographers Guild forum, where he posted these filters for the community there.

[stdlib-335] New command lines3d transforms a 3D mesh as a set of segments that can be modified afterwards (e.g. to display 3D normals, as in the example below).

[stdlib-335] New command colorize3d set the color of 3D object’s primitives according to a specified formula f(x,y,z). Useful to view colored information on 3D meshes.

[stdlib-335] New commands expand and shrink replaces deprecated commands expand_x, expand_y, expand_z, expand_xy, expand_xyz (and same for shrink_*).
[stdlib-335] New commands rescale2d (shortcut rs) and rescale3d (shortcut rs3d) perform 2D and 3D image rescaling with aspect ratio preservation. These two commands can replace the following commands (then leaving the stdlib): resize2dx, resize2dy, resize3dx, resize3dy, resize3dz, resize_ratio2d, resize2din, resize3din, resize2dout, resize3dout.
[stdlib-335] New commands compress_to_keypoints and decompress_from_keypoints allow to apply a RBF/PDE-based compression algorithm, that is particularly efficient for images with very smooth content (such as 3D CLUTs or light leak images).

[stdlib-335] Command edgels has been recoded from scratch and can now return multiple lists of edgels, either starting from the same pixel, or from any shape pixel present in the image.
[stdlib-335] New command split_vector split an image into several parts, where specified vector is the separator.
[core-335] New concept of subcommand: A subcommand of a command foo is a command whose name starts with __foo (e.g. __foo_parse). Contrary to a normal command, a subcommand shares the variables it defines, with the calling command. Example:

__foo_define_var : 
  var=3.1415926

foo : 
  __foo_define_var
  echo "var = "$var   # Will print '3.1415926'.

[math-core-335] New function flood(_#ind,_x,_y,_z,_tolerance,_is_high_connectivity,_opacity,_color) performs a flood fill in image [ind] (or in default image selected if ind is not specified) with specified coordinates. This is the math evaluator analog to command flood.

Version 3.3.4:

[gmic-qt-333] New filter Rendering / Random Signature.

[gmic-qt-333] New filter Degradations / CRT Phosphors.

[gmic-qt-333] New filter Deformations / Square to Circle [alt], that warps the image so that every centerted square (or rectangle) becomes a circle (or ellipse), or vice-versa.

[gmic-qt-333] New filter Black & White / Filaments, that throws thousands of particles from the image borders and deform their paths according to the image geometry.

[gmic-qt-333] New filter Degradations / Noise [Gradient] adds noise to image gradients (rather than image values) then reconstruct the corresponding image by solving the Poisson equation (with FFT).

[stdlib-333] New command canny , and the filter Edges (Canny) perform Canny edge detection on selected images.

[core-340] Command mmul can be now used for pointwise matrix-vector multiplication when specified right-hand image is vector-valued.
[core-340] Command polygon now defines a way to also draw open polylines rather than closed outlined or filled polygons.
[core-340] Command polygon accepts that polygon coordinates are provided as an image (e.g. polygon[canvas] [coords],1,255).

Version 3.3.6:

[stdlib-336] Command input_obj has been improved to search for texture files also in current path, when wrong path has been specified in the .mtl file.
[stdlib-336] Command plasma has been implemented as a custom command.
[core-336] Improved parsing of special input string (val1,val2,...), so that the order of specified axes is taken into account when constructing the image.
[math-core-336] Improved management of string literals and constant vectors, avoiding constructing them multiple times when they are used in loops.
[math-core-336] Improved management of hexadecimal and binary literals, as well as hexadecimal and binary number parsing from strings (function s2v()).

Version 3.3.4:

[math-core-334] Removed pre-defined variable v in math evaluator (use u(-1,1) instead).

Version 3.3.3:

[math-core-333] Function permut() has been renamed as perm().
[core-333] G’MIC interpreter now discards possible comments passed in the commands_line argument of G’MIC API functions.

Version 3.3.6:

[math-core-336] Defining a binary litteral was limited to 32 bits on Windows (and 64 bits on Linux) , due to the fact that long int on WIndows is 32 bits only. Now works with 64 bits for both systems.

[math-core-334] Fix possible side effects in math evaluator, that happened when math compiler was trying to optimize the use of some operator (e.g. x=3; (x^1)=4 was setting 4 to variable x).

Version 3.3.3:

[gmic-qt-333] Fix management of dynamic interfaces (for filters that use it) when the “Preview” box is unchecked.
[core-333] Fix wrong parsing of xN repetition suffix in input command.

Version 3.3.2:

[math-core-332] Fixed functions to remove elements from a dynamic array. When the array became too large, suppressing elements was not possible.

Version 3.3.1:

[gmic-qt-331] Fix aspect ratio of preview error when using gui_error_preview.

I would like for display to generate all of the image information on the CLI at once without having to click on images on the display. display is ever only going to be used for knowing what the output would be.

lylejk · September 10, 2023, 9:55pm

Still hoping for a variable density Hilbert fill option (why not add to the wishlist). lol

( is correct, not &#40. (see HTML Symbols | HTML Emojis).

David_Tschumperle · September 11, 2023, 6:33am

This is not practical to do this if you have a lot of images (e.g. 100+) to display at the same time.
This overflows the terminal with information that is probably too detailed for the average person.

Workaround: You can define the following command:

my_display : 
  v 1 print 
  v 0 display

Reptorian · September 24, 2023, 3:15am

Can I set this to default display?

David_Tschumperle · September 25, 2023, 8:05am

Rather use:

$ gmic update

Then set global variable _display_print_images to inf, in your cli_start command:

cli_start : 
  _display_print_images=inf

Reptorian · September 25, 2023, 3:33pm

It works though I have to wait for it finish printing before displaying images.

A simple case test:

$ +pal *

The above generates all of the palettes available within +pal which is 385 palettes.

David_Tschumperle · September 25, 2023, 4:35pm

That’s precisely why it’s actually not a good idea to print all images, and why I’ve limited it to the first 5 images by default.

David_Tschumperle · October 5, 2023, 1:17pm

2023/10/05: Release of G’MIC 3.3.1.

lylejk · October 10, 2023, 8:39pm

Any way possible to add an avoidance mask for Packed Ellipses, David? Would be cool to use such a mask with some of my circlism renders. Anyway, just trying to be the noisy wheel (to get the grease). lol

Hi,

I’m on 3.3.1pre#23093022 and just updated the filters.
Does it replace ispercentage ?
A few filters are now broken and output this kind of error :

Invalid right-hand side; Unrecognized function call 'ispercentage(0)' in expression 'round(ispercentage(0)?w*0:0'.

Some filters affected:

fx_channels2layers 
fx_clut_from_ab 
iain_cmyk_tone_p
fx_apply_haldclut 
apply_from_clut_set

maybe more?

No, that the opposite: ispercentage() replaces ispercent().

Ah, so maybe i have to rebuild a more recent version?

David_Tschumperle · October 18, 2023, 7:39am

Yes, definitely.
Version 3.3.1 has been released (currently the latest stable), and is no longer in “pre-release” mode.

@David_Tschumperle I have a question, is there any plan for 16-bit support on the GUI color selector?

David_Tschumperle · November 5, 2023, 6:57pm

Probably not unless the Qt-widget for selecting color goes to 16bits.
