I'm happy to announce the release of a new version (numbered 1.7.8) of the G'MIC image processing framework. As always, I encourage upgrading to this new version as soon as possible .
In particular, note that this version is not backward-compatible with the previous one (1.7.7), meaning that all new filters added here and new future filter updates will be only available for versions >=1.7.8.
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 1.7.8, as compared to the previous stable version 1.7.7.
seq(size,x,fnx) = ( V = vector#size(); for (#x = 0, x<size, ++x, V[x] = fnx); V );
A = seq(10,k,(k+1)^2); # will set A = [ 1,4,9,16,25,36,49,64,81,100 ];
[stdlib] New command
-input_sample (eq. to
-is) returns a sample image that can be used for quick tests with G'MIC operators and pipelines (e.g:
$ gmic -is lena).
[stdlib] New command
-display_quiver (eq. to
-dq) renders a field of 2d arrows from an image of 2d vectors (similar to
-display_tensors but for displaying 2d vectors).
[gimp] New filter Rendering / Barnsley fern is a GIMP plug-in interface to the command
[gimp] New filter Patterns / Crystal background renders multiple colored polygons to create cool geometric patterns.
-polygon has been recoded from scratch, and now uses multi-threading (through OpenMP) to rasterize a polygon on an image.
[core] Add optimizations for median computation from a set of 5,7,9 or 13 values.
-display_tensor has been recoded from scratch, using the new features of the math parser. The command is faster to render, allows tensors to have an outline and to overlap.
[stdlib] Add optional
[guide] argument to command
-nlmeans (similar to the guide argument of commands
[gimp] Improvement of filters Custom code, with optional debug information displayed on the preview window. It also supports multi-layers as input now.
[gimp] New "Duplicate" options for parameter
Preview type. Now the user has additional choices
Duplicate bottom and
[gimp] Two environment variables
preview_height are now passed from G'MIC to the G'MIC interpreter. It should ease the rendering of good-sized preview by filters that change the image size or that work with several input layers.
