  Perspective shadow help
Posted by: LisaRH72 - 05-20-2018, 08:58 AM - Forum: General questions - Replies (2)

Hello,

I've been trying to add a shadow to the attached image - I want the shadow in front of the image with a light source being behind the subject to the left.

I just can't figure it out. I've tried Drop Shadow & perspective shadow but can't find any way to add it to the front. I've also tried Gmic and Layers Effect.

I'd really appreciate any advice as it's slowly driving me mad this morning! 

Thank you for any help and advice,
Lisa

  GIMP 2.10 constantly crashing while painting
Posted by: Nerrel - 05-20-2018, 01:56 AM - Forum: Windows - Replies (1)

I've been using 2.8 to do texture work for a very long time without any major issues, but after updating to 2.10 and proceeding to use it in the exact same way the program keeps abruptly closing with no warning, no errors, and no chance to save my work.  It seemed to happen most frequently when working with multiple windows open, but it just now happened twice in a row while working on a single image.  This basically renders GIMP totally unusable, as I can't keep throwing work away every time the program dies- the odds of a crash or completing a texture without issue are about 50/50, and it's very easy to forget to save when focusing on the work I'm doing. 

I use a Huion drawing tablet and am usually using it to draw when the crash happens; it doesn't appear to happen when the program is inactive, it's always when I'm in the middle of something.  I need pressure sensitivity and never work with just a mouse alone, so I can't say whether it happens as frequently then.

I'm not able to go back to 2.8 since I now have many files saved in the new format...  Where can I begin troubleshooting this?  Are there any crash dumps or logs I can find?  I'm on Windows 10x64 and using the latest drivers for all my system. I tried uninstalling and then reinstalling GIMP over again, but the issue persists.

  Combine 3D render image and real image
Posted by: Christophpher - 05-19-2018, 11:56 PM - Forum: General questions - Replies (2)

Hello GIMP forum, 

I hope someone would be so kind and help me with this challenge. 

I will like to combine an image of a soccer player and a 3D render image I have created. So far I have been able to put the two pictures together.. But I need the final touch to make it look more 'real' or 'life like:

Do any of you have some suggestions of what I can do? I have put the different files that I am using into a dropbox folder: 
https://www.dropbox.com/sh/xkq2fek0sluk4...y05Va?dl=0


Please feel free to guide and show me what is possible - that would be a great help for me. 


Thank you, 
Christopher

  Gimp 2.10 with old vignette.scm from Plugin registry.
Posted by: DenisT - 05-19-2018, 01:45 PM - Forum: Extending the GIMP - No Replies

Hi, my first message in here  Smile  don't know much about scripts and all, but I really wanted this to work...

So I installed Gimp 2.10 and quickly found out that many scripts would generate errors.
Sadly one of my favorite (Vignette script) from:
Dom_C at "http://registry.gimp.org/node/17267" would not work anymore.

The first error was: Error: eval: unbound variable: NORMAL
Quit Gimp
So I open the script file "vignette.scm" for me it was in:
"C:\Users\username\AppData\Roaming\GIMP\2.10\scripts\"
I search for the word "NORMAL" and replaced it with a zero "0"

Re-started Gimp and tried again.
Then second error was: Error: Procedure execution of plug-in-gauss-iir failed...
Quit Gimp
Again in the script file "vignette.scm":
I search for the word "plug-in-gauss-iir" at this point I did many trial and error to finally figure that it was with the radius so I searched for "radius" and finally found this line:
"(theRadius (* inRadius (/ (max theWidth theHeight) 25) ) )"
I replaced it with a different value like this:
"(theRadius (* inRadius (/ (max theWidth theHeight) 400) ) )"

Tried it with images of "RGB color 8-bit gamma integer" and
"RGB color 32-bit linear floating point 6000x4000"
and it worked for me Smile
I hope, for those who like this old script, this will help..
Have a nice day.

  fade in-out
Posted by: gimp-artist - 05-19-2018, 12:49 PM - Forum: General questions - Replies (2)

Q1. I know how to fade-in or fade-out for paint brush. What I don't know is how to do the both fade-in and fade-out together. Is it even possible?

Q2. I'm creating a new dynamic for fade parameter. Color and Angle works for fade-in perfectly, but color and angle doesn't work for fade-out. Strange. Am I wrong?

  paint mode - color erase mode
Posted by: gimp-artist - 05-19-2018, 05:34 AM - Forum: General questions - Replies (2)

   
I'm testing "color erase" mode for paint tool. Background color is cyan. I painted blue color on it in the "color erase" mode. Then the green color came out. It is fine.

Now background color is yellow. I painted red color on it in the "color erase" mode. I'm expecting green color for the result, but nothing happens. What's wrong with this approach?

  paint mode
Posted by: gimp-artist - 05-19-2018, 01:11 AM - Forum: General questions - Replies (2)

   
Paint mode is not working like the doc says.

When I paint on an image with only one layer with some paint mode, I can paint on it. I don't understand. Modes supposed to be working on two layers, right?

Even on two layers, the result is the same as the image has no additional layers.

What am I missing for paint mode?

  Problems file-png-save-defaults
Posted by: Petequero - 05-18-2018, 11:33 PM - Forum: Extending the GIMP - Replies (1)

Hello guys, 

I am new here, and I wrote my first script-fu. 
Unfortunately, it does not work (yet Big Grin)


My script is about resizing png images, and then save them. 
The script seems to be working for the resizing. 
However, I don't manage to save the new pics. 

I am working on windows 10 with GIMP 2.10. 
My code is below. 

Any feedback would be appraciated Smile

Code:
(script-fu-register
           "script-fu-resize-theimages"                    ;Nom de la fonction (console)
           "Redim"                                          ;Nom du sous menu dans l'onglet /File/Create/Redimensionnement Image
           "Redimensionne tes images png de la taille\    
             que tu veux, et avec l'interpolation\
             que tu veux. Trop cool isn't it ?"            ;description

 (script-fu-menu-register "script-fu-resize-theimages" "<Image>/File/Create/Redimentionnement Image") ; create a menu
 
 (define (script-fu-resize-theimages sourcepath inInterpol inWidth inHeight destinationPath); On défini une fonction d'entrée qui prend les 3 paramètres du menu défini plus haut
   
    (let*
        (

                ; On définit la variable image (pour les fonctions)

                ; On définit de la variable drawable
                (drawable (car (gimp-image-get-active-drawable image)))

                                (cadr (strbreakup first-filename "\\")) ;image.png
                    )
                    
                )
            )
            
            ; On défini l'interpolation
            (gimp-context-set-interpolation inInterpol)
            
            ; Et finalement on lance le redimensionnement
            (gimp-image-scale image inWidth inHeight)

            ;fermeture de l'image
            (gimp-image-delete image)
        )
        
        ; On supprime les "chemin/image.png" déjà fait
        (set! filelist (cdr filelist))
        )
    )

Thank you in advance for any comment.
