When I (beginner) started using GIMP 3.0.6 with G’MIC 3.6.3 a few weeks ago, everything worked perfectly. Then, suddenly, the preview for the Artistic → Comic Book filter changed drastically.
Previously, the preview showed the entire picture, but now it only displays a small portion of the image at full screen. There’s no way to zoom out below 100%. In addition, the colors (and even the style!) in the preview don’t match the final result.
Does anyone have an idea how to fix this? Thanks in advance!
Sorry that nobody replies, I think David is out of town and he would normally at least give a reply and he also uses Gimp so he would have insight there too.
I don’t use Gimp anymore lately but I know that in the normal GUI version of gmic there is a setting that is ‘always enable preview zooming’ and when disabled it won’t go below 100%.
And in the regular GMIC GUI version you also can activate the ‘internet’ checkbox and press update (the circular arrow) which applies fixes to small errors that slipped in GMIC during recent development.
Of course your issues with could also be some other part of the operating system of your computer, hard to tell if other users don’t share their experiences regarding the comicbook filter.
For me the filter seem the same as always and the preview seems to match the output now that I did a quick test.
@Ich_Selbst Welcome to the forum. To solve this problem (result matching):
Technical solution: You need to modify or override the *.gmic file that contains all the filters from:
cl_comic_preview(0)
to:
cl_comic_preview(0)*
I am one of the busy ones, so that tip is all I have the time for. Either dig around the documentation at gmic.eu or enlist the help of other G’MIC folks such as @Reptorian or @prawnsushi.
Briefly, normally, G’MIC only processes the preview of the image, not the original to ensure a fast preview. However, that means the result may be very different from the preview. The * tells G’MIC apply the filter to the entire image. The number, e.g. (0), tells G’MIC’s preview the preferred zoom level.
Simpler but tedious workaround: Apply filter then undo in GIMP. Repeat until you have arrived at the desired result.
