G’MIC 1.7.4 更新日志
新功能:
[stdlib] New commands -fade_files, -fade_video, -morph_files and -morph_video which compute a streamed temporal fading/morphing of a sequence of images (given as an input filename pattern, or a video file).
[stdlib] New command -is_videofilename that try to guess if a specified filename is a video file (guessing by its extension).
[stdlib] New command -x_grab_color displays a color grabber widget from an input image.
改进:
[core] Command -rotate is now able to rotate volumetric images around any 3d axis, with an arbitrary angle.
[core] In math parser, user-defined macros can now use function or operator names as argument (e.g.foo(x,y,fn,op) = (fn(x))op(fn(y))).
[core] Filter/command updates have been merged into a single update file for the CLI and GIMP interfaces of G’MIC.
[core] Improve nearest-neighbor computation in a few functions of the CImg Library.
[stdlib] Improve “streamed” commands -apply_files, -apply_video, -average_files, -average_video, -median_files and -median_video.
[stdlib] Command -x_colorize and associated GIMP plug-in filter Colorize [interactive] can now display a color grabber widget, to let the user choose colors from any input image he wants.
[web] Repository gmic-minimal has been removed. Repository gmic has been cleaned and is lighter. The ZArt and libcgmic codes have been moved to repository gmic-community.
Bug 修复:
[core] Fix orientation when dilate/erode image with non-symmetric kernels.
[core] Fix routine to compute a rotation matrix around a 3d axis (angle was reverted).
