Release of G'MIC 2.5

David_Tschumperle · April 9, 2019, 5:43pm

This should be now fixed, with commit https://framagit.org/dtschump/gmic/commit/f246594626be513f522d34c0b92dfdb2022eb7f9

Please try pressing the Update Filters button, and tell us if that solves the issue !

Thanks! It works again.

Very good. It would like me modify Warp to see if I can create an ARAP for gmic.
Where creates a guide on the drawing but does not modify too much the radial distance between the points.

Could you modify interacitve warp so that have exponential falloff between points ?

Also a request for fractal map filter like this

Reptorian · April 10, 2019, 5:16am

I’m more interested to see elevation map generator. We actually have normal map support in G’MIC, so in theory, it should be possible to make something like that, but one would need to know how to make a elevation map with the quirk of textures in it. I do have some ideas though based on luma-maps.

Changelog for version 2.5.7 (released on 2019/04/16):

New features:

New command x_morph opens an interactive morphing editor from two (or more) input images. New filter Deformations / Morph [interactive] makes it available from the G’MIC-Qt plug-in.

New command remove_named (shortcut rmn) removes images in the list with specified names, if any.

Improvements / Changes:

Built-in colormap lines in command map has been redesigned from scratch. This high-contrast colormap is intended to be used for displaying maps of labels. This colormap has been generated by solving an optimization problem (see new command lut_contrast).
Command lut_rainbow replaces rainbow_lut.

Bug fixes:

Command onfail : fix interpreter bug that prevents loops working correctly in local...onfail...endlocal environments.

Reptorian · April 13, 2019, 2:59pm

Really digging the morph feature.

hover · April 13, 2019, 4:58pm

Request for branches patterns in Gmic:

afre · April 13, 2019, 10:13pm

Oh no, she is blowing up!
… Okay, all is well.

Fun request. Someone make @David_Tschumperle (sp david) stick out his tongue like Einstein.

In macos with GMIC 2.5.6 for Gimp I have an error when trying to use the Color Presets and Simulate Filter

**** Error in ./fx_color_presets/*if/clut/*local/*if/if/ *** Command ‘output’: gmic::fopen(): Failed to open file ‘/Users/my user/.cache/gmic/gmic_cluts.gmz’ with mode ‘wb’

**** Error in ./fx_simulate_film/*if/clut/*local/*if/if/ *** Command ‘output’: gmic::fopen(): Failed to open file ‘/Users/my user/.cache/gmic/gmic_cluts.gmz’ with mode ‘wb’.

The file path does indeed not exist. Note that all other programs cache is located in a slightly different address:
‘/Users/my user/Library/Caches’

In that path there was no gmic folder. I have created it and dropped the file gmic_cluts.gmz (found at https://framagit.org/dtschump/gmic/tree/master/resources). The error persist

MacOS Mojave
GIMP 2.10.8
GMIC 2.5.6 from https://github.com/aferrero2707/gimp-plugins-collection/releases/download/continuous/GMIC-Gimp-2.10-OSX.tgz

gmic_gimp_qt and the related GMIC folders installed at:
/Users/my user/Library/Application Support/GIMP/2.10/plug-ins/GMIC/

Hi, I am using a similar configuration, still seemingly not similar errors. Although I rarely use the color transformations.

My most serious concern is the name of your user account! Please try the same with an account name WITHOUT SPACE! If that is not printed for that mail.

Last idea, prove that ~/.cache/gmic is writable for the actual user! (drwxr-xr-x)

@Carmelo_DrRaw post #83.

KaRo · April 16, 2019, 8:41am

Hi David,
I have tried to trace the ways clut is trying to find gmic_clut.gmz under

MacOS Mojave 10.14.4
Gimp-2-10 from gimp.org
gmic_qt_gimp from @Carmelo_DrRaw

and trying to reduce the network access to this file.

Here is an excerpt calling clut from customs call under gimp. All these pathes are only valid for the gimp I am using…

[gmic]-0./fx_custom_code_preview/*local/*if/fx_custom_code/*if/_fx_custom_code_start/clut/*local/ Set local variable 'path_clut=/Users/karo/Library/Application Support/GIMP/2.10/cache/gmic/'.

[gmic]-0./fx_custom_code_preview/*local/*if/(...)/clut/*local/*if/*repeat/ Set local variable 'file_clut=/Users/karo/.cache/gmic/gmic_cluts.gmz'.

On my machine only .cache/gmic and .config/gmic exist. Under $TMPDIR there is no folder plug-ins. Nowhere is the file gmic_cluts.gmz found, hence it is tried to be written under

[gmic]-552./fx_custom_code_preview/*local/*if/(...)/clut/*local/*if/*if/ Output images [0,1,2,(...),549,550,551] as gmz file '/Users/karo/Library/Application Support/GIMP/2.10/cache/gmic/gmic_cluts.gmz', with pixel type 'auto'.

which fails since the gmic folder under cache does not exist by default.

I think one possible solution might be to test if the folder gmic exist and create it if necessary !

David_Tschumperle · April 16, 2019, 8:43am

That is interesting, thanks for reporting.
What I’d like to know is “What would be the best path for storing cache files, i.e. the equivalent of $HOME/.cache/ in Linux ?”
I thought it was the same, but apparently not.

KaRo · April 16, 2019, 8:51am

The gimp I am using stores in ~/.cache
I don,t know about other builds (Partha, MacPort, home-brew)

From my point of view ~/.cache/gmic would be good. In fact for the cli I have GMIC_SYSTEM_PATH defined (in .bashrc), however the Mac don’t honor such definitions for the desktop apps.

David_Tschumperle · April 16, 2019, 8:52am

So, Karsten, what

$ gmic e '${-path_cache}'

displays for you, on Mac OSX ?

KaRo · April 16, 2019, 8:57am

from cli of course

/Users/karo/.cache/gmic/

from GIMP

/Users/karo/Library/Application Support/GIMP/2.10/cache/gmic/

Maybe interesting too: If starting gimp under Desktop, the typical way for Mac users, it finds faves. If I start it under Terminal, to catch the output, it does not find most of the routines called under faves!

David_Tschumperle · April 16, 2019, 9:00am

So that means GIMP redefines $HOME to be /Users/karo/Library/Application Support/GIMP/2.10 ? That is insane !

KaRo · April 16, 2019, 9:04am

Insane or not, that is the place where under plug-ins the plugin exec and library folder is located! I think it is a consequence of the packager decision how to link and combine the package. Think about all those problems with windows!

This my way to find out about those patches under gimp

David_Tschumperle · April 16, 2019, 9:07am

Karo, what I’m trying to say is I determine the ‘cache’ folder for G’MIC with $HOME/.cache/ on Linux and MacOSX, so if $HOME is redefined, it will point to a garbage path that does not exist, which seems to happen for you when GIMP is launched.
I don’t have many other ways to determine the correct Cache folder if $HOME is redefined.

That really looks like a bad idea to redefine $HOME when GIMP is run.

What other solution I have on my side then ?
