  Auto whitebalance from command line
Posted by: balancedeblancos - 2 hours ago - Forum: General questions - No Replies

GIMPs Color->Auto->Whitebalance tool does more or less exactly what I want. But I want to run it on a single image from command line but it doesn't seems to be that easy.

There are many SCM scripts out there that does some sort of white balance but not using this menu item directly like this Luca De Alpharo's white balance script linked from this post https://www.gimp-forum.net/Thread-White-...te+balance

In the GIMP source code I can see that histograms are extracted for each RGB channel for Color->Auto->Whitebalance and but in the SCM above there is no histogram extraction and the same applies for a few other white balance scripts I've found.

How can I run GIMP Color->Auto->Whitebalance from the command line (without user interaction) or at least something very similar?
ilar?

  Gimp is distorting imported images
Posted by: mike_o - 6 hours ago - Forum: General questions - Replies (2)

I use a program called knobman to create custom knob skins for music software.

The one real limitation to knobman is that it can only do 8 items on a list type graphic, see image.

when I need to make a list graphic that is more than 8 long I will make 2 separate lists and combine them in gimp.

this has always worked fine, until recently I updated to OSX catalina and did a fresh re-install of all my programs, now gimp is causing this issue.

   


the text at the very top that says "Voice To Pitch" is exported directly from knobman and looks exactly as it should.

the text below that which says "Natural, Quantized, Major" etc... has been imported into gimp and stitched together to create a longer list and then exported back out, but it's made the text fat and a little blurry.

does anyone have any idea how to correct this?

Thanks.

  Difference between image and print preview
Posted by: blimpgreen - 8 hours ago - Forum: General questions - No Replies

I have an image that looks perfectly fine in the normal editing mode in Gimp, but when I go to the printing dialog, the print preview image is significantly different. The image shown in the print preview is overly saturated and darker, and I've tried to change options in the print dialog like "Color Mode" and "Quality" but there's no effect on the print preview image. The print preview image is a more accurate representation on what actually is printed though, so in that respect the print preview works.

What are my options if I want to get the print preview and the printed image closer to what I see in Gimp? Do I have to desaturate and lighten the image before I attempt to print it or is there a smarter way to get the print preview and printed image more in line with what I see in the normal editing mode?

Hi, is there any method scale a small piece of semi-transparent noise pattern to use with an HD wallpaper.

I will explain. I had one pattern like this made for a button. I would like the wallpaper to have the same texture. Either I should go through the whole process of remaking the noise or find some way to scale this small image. Any help will be great.

PS : I have Resynthesizer plugin

Photo gradient fill with symbol
Posted by: teespringgig - Yesterday, 02:21 AM - Forum: Gimp 2.8 questions - Replies (6)

Hello everyone,

I'm new to using gimp 2.8 so I could really use some help. I'm trying to create a gradient pattern, similar to the design attached.

Does anyone know how to recreate this gradient? I've tried using the gradient tool various ways but it only seems to go from gold to white.

If anyone has any ideas please let me know.

  Help: Drop shadow is creating a strange outline in one text
Posted by: aridavid5 - 05-26-2020, 10:38 PM - Forum: General questions - Replies (1)

A bit of background. I have 2 text layers that are a duplicate of one another. However, drop shadow is acting weird on one of them. I even duplicated the one working again to replace the other, and I got the same error.

In the top screenshot you can see how I expect it to work (how it always had before), and in the bottom one you can see that it is creating a weird black outline.

EDIT: After changing the precision, to interger instead of floating point, I stopped getting the error. Now I'm even more confused.

Hello,
is there a way to make the letters of a text along a path over a half-moon shape keep their proportions without distorting. Because each time the big letters have the outer part much wider. Thank you

  Image distortion for historical comparisons
Posted by: Piblo - 05-25-2020, 11:34 PM - Forum: Extending the GIMP - Replies (2)

Hello,

I would like to take photos of places photographed in the past (old postcards), to show the changes. The problem is that, even if we have found the place from which the old photo was taken and a roughly equivalent field width, distortions appear and make the photos noticeably different.

I wonder wheter Gimp transformation tools are suitable for this purpose. I tried most of them - most especially the unified one - but, even if they give some interesting results, I am not fully satisfied. Please, could you advice me ?

I imagine a tool which would consist in defining pairs of dots (one on the old photo, the other one on the recent photo) as done with Hugin when assembling photos to make a panoramic views. Then the distortion f the new photo would be computed. Do you know if such software exist ?

I hope having asked my question in the right section.

Thank you in advance for your help.

Regards,
Piblo

  How to know what Auto Input Level does?
Posted by: ajax - 05-25-2020, 03:53 PM - Forum: General questions - Replies (9)

Maybe I posted this question in the wrong forum.

My assumption is that "Auto" means to algorithmically do what the user could have done by manually exercising the various controls.  If so it would be most helpful to display the results in the dialogue window in the various display areas that get updated when the controls are exercised individually be the user.  Might it make sense to be able to save a good result as a preset?

Also, while good, sometimes the algorithm "over does it" just a bit and the user ought to be able to tweak it just a bit.  The way I'm doing it produces no clue about what was done that may have been a pretty darn good place to start.
