| trouble with GMIC QT installation (solved) |
|

Since a few releases of both GIMP and GMIC, I have a recurrent error each time GMIC is invoked from filters list. The filters are running in the end, but I have to acknoledge many error windows.
Error message say that "blablabla entry point in xyz dll is not found". I think after several unsuccessful attempts, Gmic manages to locate and load adequate DLL's .
I think the mess in directory path is due to several historical version of gimp that are still present on the computer : at install time, GMIC qt is probably fooled and get installed at the wrong place, thus causing subsequent errors.
The work around solution is to seek and uninstall all "fossile" occurence of GIMP and GMIC. I have used uninstaller of GIMP, and uninstaller also when they where found in gmic directories. After that, I have erased (yes, this is somewhat brutal) all old directories related to GIMP / GMIC.
I have lost customization settings but it was not critical at that point. Make simply sure to save your settings (i don't know how to do it) and also the references of your favorite add-ons , so that you can reinstall them.
So far so good, GMIC is accessed flawlessly without any error window popping up.

Hey guys,
I installed a plugin to test it but I can't find it anywhere.
I looked inside the Python-Fu menu, I didn't find it.
Also in Filters - Python-Fu, without success.
In fact I'm not even sure what the name of this plugin would be.
Could anyone reveal the location of this plugin? Please!
Below is the plugin code:
Code:
#!/usr/bin/env python
#grow-shrink-live.py
# Creator: TT
# This should allow user to adjust grow/shrink current selection with live preview
# Open Source

global_param4 = 0 #in this example it's enhance_shadows

Batch export all opened images at once V2 (more options) |

Related to this one > https://www.gimp-forum.net/Thread-Export...MP-at-once ,
if it's your first time here, this script is an .scm to put in the scripts folder and it will export ALL opened images at once (batch export) to the format you chose like JPG, WebP, PNG, TIFF, BMP, and even export animation and BigTiff,
yes all your OPENED images at once! (click on the link above to see used cases  )
What's new in version 2? and the last! (delete the previous file (sg-save-all-open-a.scm), although I did change the declaration so both could work side by side)
You can control your inter-action.
> Fully auto,
> Fully Manual
> or use the latest settings used per image in fully auto (you have to RTM, though, for that last option)
Oh.. and last but not least I also wrote a manual (ReadTheManual) with screenshots 
And few other updates like BigTiff is accessible as well as animated WebP (explained at the end of the RTM), etc...
Download:
pxl-export-all-images-as.7z (Size: 271.91 KB / Downloads: 592)
After Rich2005 inspiration, this second version is due to Ofnuts who did try to put me on the right path (pun non intended)

Hello, forum people! 
I’ll tell you about a situation that I can’t figure out without the help of experts in this topic: I tried to cut out a glass, but couldn’t make it transparent for the background on which I placed it 
Can anyone tell me how to place transparent objects while maintaining their transparency?
I would be very grateful for your help in this matter!

Привет, обыватели форума!
Расскажу о ситуации, с которой не смогу разобраться без помощи знатаков в этой теме: Попытался вырезать стакан, но не смог сделать его прозрачным для фона, на который его поставил
Кто может подсказать, как можно ставить прозрачные объекты, при этом, сохраняя их прозрачность?
Буду очень благодарен за вашу помощь в этом вопросе!

Привіт, люди форуму!
Спробував вирізати склянку, але не зміг зробити її прозорою для фону, на яку її поставив
Хто може підказати, як можна ставити прозорі об'єкти, при цьому, зберігаючи їх прозорість?
Буду дуже вдячний за вашу допомогу у цьому питанні!

RUN-WITH-LAST-VALS in Script-Fu is not what you might think |
|
Posted by: PixLab - 12-09-2023, 01:49 AM - Forum: Scripting questions

This RUN-WITH-LAST-VALS gave me a hard time, thus this is what I discovered on how it behaves (Related to this thread)
RUN-WITH-LAST-VALS Works per image session (ID would be correct), RUN-WITH-LAST-VALS cannot be transmitted to another opened image.
Thus if you have a bunch of images opened, you cannot run first RUN-INTERACTIVE on the first image to export and then RUN-WITH-LAST-VALS for the other images, thinking it will use the last settings you did use on the first image... That Will Not Work
How it works?
Example I want to export 5 opened images as JPG, but previously I did exported [Image 1] and [Image 3], the RUN-WITH-LAST-VALS will run like RUN-NONINTERACTIVE using the last values it found in the Image's session/ID in [Image 1] and [Image 3]
But will run RUN-INTERACTIVE for image [Image 2], [Image 4] and [Image 5], because there is no history in those images' session/ID of an export (whatever type of "Export")
There is also a "caveat", you export a second time but with another image/file type,
For example you did export all your images as PNG first, but you want also to export a second time as WebP to put on your website.
If you chose RUN-WITH-LAST-VALS, it won't ask you any question this second time it will run as RUN-NONINTERACTIVE for the WebP (or any other type) because in the image's session/ID it's "marked" as already exported...
But I don't know were RUN-WITH-LAST-VALS takes the values from PNG to transfer to WebP, because they are quite different, especially the options...
Anyway, I hope this help the first timer with Script-fu to not struggle to understand that behavior, like I did
