  Importing color index from .PNG?
Posted by: Jere Sumell - 12-25-2020, 07:23 AM - Forum: General questions - Replies (6)

I'm quietly new to GIMP Software even I have long history in Free and open Software and Linux World under GNU License and photography and some stuff in commerical image processing tools.

I started to takeover GIMP advanced use by reading book "GIMP Bibile" and i stucked to Color index with Google keywords "Disney Color Index" and "Super Mario Bros Color Index".

I understood that I can convert color index from ie. RGB to indexed so little bit fun for Christmas Day I'm try to comvert some of my images to Original Disney Colors.


There's a website under "Colorscheme.com" -domain name where visitor can download color index in .PNG format. My Question is How to import Color Index from .PNG -format to my active GIMP -project.

Example straight link reference to "Classic Disney Color Scheme" @ Colorscheme.com
Classic Disney Color index @ ColorScheme.com

  commercial use of the gimp
Posted by: mmcnally256 - 12-21-2020, 10:29 PM - Forum: General questions - Replies (2)

I'm going to use some technical drawings, I created with the Gimp, to try and create some personal revenue.  Are there any commercial rights license that I need to purchase, to be legal?  I will donate if it pays off, but for now I just need to be legal.  Thanks

  GIMP language DE??
Posted by: gNeandr - 12-20-2020, 08:17 PM - Forum: Linux and other Unixen - Replies (2)

Installed GIMP 2.10 from https://www.gimp.org/downloads/index-comments.html but also from https://www.gimp24.de/gimp_download_linux.php in the hope to get the locale UI version for DE. And also using https://wiki.ubuntuusers.de/GIMP/ only gives the EN version.

Maybe it's because my operating system is

Code:
System:
  Kernel: 5.4.0-54-generic x86_64 bits: 64 Desktop: Xfce 4.14.2
  Distro: Linux Mint 20 Ulyana

 with the language setting for EN.

However, I assume there is a method to get a GIMP DE version to work, just how ?  (Without changing the base OS EN version!).
Any help is greatly appreciated, thanks

  How can I color-match an image?
Posted by: Marscaleb - 12-20-2020, 05:13 AM - Forum: General questions - Replies (2)

I'm looking for a good method to color match an image.

I'm working with textures I want to use in a game, and I could have something like say a brick texture with nice grey-blue bricks.  Well, the other textures I'm using in this area have a brownish-yellow color to them.  I want to adjust the color to make the grey-blue bricks match the brownish-yellow of my other texture.

I've tried using Colors -> Hue-Saturation, but I can never seem to get it to match.  I've tried using colorize but makes everything the same color, and thus it loses things like the variation in saturation.
And I think part of the problem is that these textures are just too detailed.  Like the brownish-yellow is actually a range of browns and yellows and I'm trying to match a texture to be a brown or a yellow.
I could imagine this being possible with a small palette, like if these were pixel-art images each with sixteen colors, I could go into the palette data and adjust those colors one by one to match the source, making the colors that are a little more grey match the ones that are a little more brown.  But I'm not working with a small palette, I'm working with large and complicated textures.

Any ideas?

  Iwarp tool - woking with preview window
Posted by: pergamin - 12-19-2020, 05:02 PM - Forum: Older Gimp versions (2.8, 2.6....) - Replies (5)

Hi All

I wish to give smile to myself in a picture (the pic. extension is now xcf). I thought to work with Iwarp tool to get this. But the picture is small in preview window. I searched the Internet to find solution. The solution I found was to: first use select tool and then the selected area will fill the preview window's space. - That is not true. The pic. in preview window is as small as in original picture (please see the picture below to see what I get). What can I do to enlarge picture in  that preview window?

  Tangents or normals to a path
Posted by: Ottia Tuota - 12-19-2020, 04:57 PM - Forum: Extending the GIMP - Replies (8)

A couple of new tools to manipulate paths.

Inkscape can do snapping to paths both tangentially and perpendically. (In Inkscape, see Document Properties > Snap, and tick the two points at the bottom.) Nothing similar exists in Gimp(?). I made a sort of "poor man's snap" to imitate that feature. It is no real snapping as in Inkscape.

The package consists so far of four plugins:

  1. Bounding box
  2. Parallel tangents or normals
  3. Tangents or normals from a point
  4. Tangents or normals from a stroke end of another path
To get the plugins, go to

http://kmarkku.arkku.net/Path_tangents_f...aster.html

and click the Download button at the bottom. That gives you a ZIP file. Unzip it and place the one file it contains (path_tangents.py) in your user's plugins folder. Start Gimp. In the Paths tab, right click some path and follow the link Tools > Tangents and normals > ...

Bounding box does what its name says. Actually the code has been finished for a long time but it was buried in another plugin, and I felt that it deserves to be a plugin on its own right. I placed it in this package since it is, loosely speaking, about tangents.

Of the other plugins I explain here number 3: "Tangents or normals from a point". The rest will follow in another post.

Tangents or normals from a point: Suppose you have a path and you need to draw a tangent to it from some point. In the picture below the Path is in blue. I marked the point with a black dot but that is only for this explanation. It is just some point in the plane. The red line is the tangent you want to draw.

   

You use the plugin as follows. Make a tentative tangent: a line segment (a path with 2 anchors), one end precisely at the point you want, and the other end somewhere close to where the tangential point should be:

   

Then call the plugin by right-clicking at Path (in the Paths tab), follow the link

Tools > Tangents and normals > Tangents or normals from a point

click it, and choose your tentative tangent in the GUI. Otherwise keep the default values. The plugin creates the tangent as a new path:

   

You can think that your tentative tangent is "snapped" to the tangential point.

The plugin offers three other inputs:
  • Tangents or normals?
  • Action
  • Extend
The first enables you to draw normals (perpendiculars) instead of tangents, and the third allows you to draw the tangent or normal with an extension. Please try these two yourself.

I explain now the Action: There are three options:
  • Draw only the closest (default)
  • Draw all for the closest stroke
  • Draw all
In the following pictures I show the meanings of the options. The path is the concentric circles. I made there a tentative tangent.

   

The first option (default) draws one tangent, closest to the tentative tangent. The second draws all possible tangents for one stroke, the closest one (here it is the largest circle). And if you choose "Draw all" you get all possible tangents for the whole path. See the picture:
 
   

If you find any strange behaviours, please report. Or if you have any suggestions, please tell me.

Sorry for the long posting. To be continued...

  Change color
Posted by: Stefsn - 12-19-2020, 09:33 AM - Forum: General questions - Replies (1)

Hello my dears. 
Am curious how restless it is here in this forum. Makes a quiet impression for now Smile

Picture A: seil_weiß
Image B: seil_braun

I would like to edit a color of a picture. I have picture A (and picture B actually not). But I made both pictures once, to be able to get the matching hue, for upcoming edits. 

So I would like image A (the rope of the trunk) to have the same hue as image B at the end, or the gradient as well. So far I have tried it with in 2 ways:

1. variant: (a la YouTube - change apple color).
1. select area of the rope.
2. create new transparent layer.
3. set color and put gradient over it and change intensity in layer settings. 

2nd variation: (a la YouTube motorcycle rim color wehcseln).
1. create layer in black.
2. set intensity to 75%.
3. erase the area to be colored. 
4. choose color selection to determine the area and then tint or colorize.

Surely both are not the professional variants. But maybe someone can help me or even say ne not possible (:
