Hello all , new to the forum - 

I am trying to clean up lines from a sketch that I scanned into my computer.  The scan settings were the highest quality I could make it.  The sketch was outlined using an artist pen but it left some pixelation around the lines.

I looked up some tutorials and most of them instructed to use the "Levels" and "Threshold" tool to rid of the pixalation.  Except that it just doesn't work!  No matter what settings I use, following all the instructions, any slider changes don't result in anything, even in the most extreme settings!  Nothing changes.  The histogram shows no information.  What am I doing wrong or is this a bug in gimp?  All of my other tools work as expected except for the two I need! Of course, it's always the way things work out..


Here is info on the file, my system.

I am running Gimp 2.8 on Windows 7 (64bit)
It was opened as a RGB, JPG file.  it is one layer

i have multiple directory's containing images all of them should get converted to xcf files and if there are files with the same name in another directory the xcf file should have all of them as layers.

as an example:

input_a/1.png
input_b/1.png
input_c/1.png

get converted into

output/1.xcf

which contains 3 layers called input_a, input_b and input_c.

any help would be appreciated.

like why dose this plugin not work?
https://www.gimp.org/tutorials/AutomatedJpgToXcf/

or are there other plugins i should take a look at?

or anything really.

Took me a while to figure out the math, but I eventually got them: the Reuleaux polygons:

   

Still a few things to do before it goes public

Hello,

I'm new at using GIMP, so probably the answer is easy, but I can't find out what I do wrong. who can help me?

Attached a xcf file with a world map. I would like to change the color of South America to blue.

I have selected South America with
Tools - selection - oval  (remark: I use a Dutch language version, so maybe some translations aren't accurate)

Then
right clic - colors - tint/saturation

In the pop-up screen I select "Green"
and move the 'tint' indicator to value 130.  In this pop-up, the color next to "G" indeed turns blue.

Finally I press OK, and expect South America to become blue, but nothing happens. What goes wrong?

Who can shine light in my darkness?  Thanks already.

Filip

Im talking about this tutorial:
https://photoshopstar.com/text-effects/p...xt-effect/

In step 4 the actual texture is created.

a.) I can imitate the 'PS Note paper Filter' with bumpmapping.
Just using a white layer with RGB noise as the bumpmap works fine.

b.) I can also sort of imitate the 'PS Stained Glass Filter' with Gimp's Mosaic filter. Here is what it looks like in PS:

   

c.) But im lost at the 'PS Glowing Edges Filter'. It seems to run an edge detect and strokes the edges with the same color of the tiny squares...

   

....because when i go higher with the values, i get something that looks similar to 'G'MIC - Contours - Morphological Filter'

   

I tried all the Edge Detect filters, but i am having no luck.
There is a filter in XnView, called 'Edge Enhance'...do we have something like this in Gimp ?

Ideas ?

Hello,

This is my first post here and I hope I do not brake any rules etc.
I have searched forums but I could not really find the answer I was looking for (or I searched wrong)

I am developing aircraft for X-Plane simulator.
The newest version of it has ability to edit how metallic and shiny object is.

Without going into details, friend of mine told me that I need to paint in blue channel with colors from black through any shades of grey to white.
This different "grayness" will give in simulator different levels of surface looking like metal.

To make object more or less shiny( reflective), I am supposed to also make a map from black-any shade of grey-white color map and paste it into alpha channel.

My questions are:

1. How do I paint in blue channel?
Can I paint in different layer with different shades of grey and then just copy and paste it into blue channel?
Do R and G channels need to be visible while I m doing it?

2. How do I paint in alpha channel?
Do I also make my grey shades map in different layer and then paste it into alpha channel?

I am sure these are the basic, trivial questions but I am not even close to feel comfortable with Gimp except routine things I do all the time with UV maps.

Please explain it to me in the simplest way possible.

Thank you in advance.

Aligning multiple radius image frames to swap in different images?

Quote:A couple of highly skilled lads have asked me to sort their postcard out.

I'm happy with the text and artisan logo concept.
The borders need tweaking as do the letter spacing... but that's fine.

The image size is almost there (to have equal borders).
It has to be 6 or 12 images.
12 shows more skills.... 6 shows bigger images.

However, the same question exists.

Okay! Since I pretty much have it memorized when I open something in Gimp (2.8).
Let's see..

Colors-Brightness 10 Contrast 5
Colors-Hue Saturation-Hue 25
Filters-Enhance-Sharpen-Sharpness 50
Colors-Levels-Middle of Input Levels 1.15
Filters-Light and Shadow-Lighting effects-Light tab (type None)-Material tab-Material Properties-Glowing 1.15
Colors-Hue Saturation-Hue 28
Colors-Levels-Middle of Input Levels 0.70

When I use basic math to combine some of those (Hue Saturation or Input Levels), it doesn't come out as intended.
I have been doing the above with screenshots of games and game textures that make objects in games appear more detailed.
Though I've done it.. probably for over a year? The process takes too long. Say, for a huge folder with thousands of game textures!
I'm looking for a way to combine all of those functions into one use somehow :­D Like one or two clicks?
