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 Smile

  Changing colors: what do I do wrong?
Posted by: FilipV - 12-10-2016, 09:53 PM - Forum: General questions - Replies (8)

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

  trying to recreate PS tut glitter texture
Posted by: Espermaschine - 12-09-2016, 01:04 AM - Forum: General questions - Replies (2)

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 ?

  RBG and Alpha channel edit workflow
Posted by: arb65912 - 12-07-2016, 12:21 PM - Forum: General questions - Replies (4)

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.

Andrzej

  Aligning multiple radius image frames to swap in different images?
Posted by: marco-gimp - 12-06-2016, 10:25 PM - Forum: General questions - Replies (11)

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.

Can I set up a layer or a layer per image, in a grid of frames, so that i can then swap in different photos, just to see how they work with each other?

How I've done it now is scale an image to required size... cut the layer... change xcf file and paste as a new layer.
Drag it around into a grid pattern.

I could first round the corners using the Decor filter
So I would then have images with rounded corners

It would work.
I think that I need to experiment with snap to grid.
But it would work.

However, I'm learning as I go, and from past experience, I've learned that there are sometimes better ways of doing a job.

Ideally, I'd like to set up a grid of maybe slightly rounded frames, and just swap in and out the images.
Is this possible, or is there a correct way of dealing with this problem?

  How do I combine all these menu functions into one?
Posted by: Culuf - 12-06-2016, 08:16 PM - Forum: General questions - Replies (8)

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?

Hi Guys!
Thanks for re-booting the forum.
I've had a right run around tonight, until I finally saw the 'it's dead Jim' note at the top of Gimptalk Big Grin

Whoever put it there as a sticky... well done!

I'm not a heavy poster, but from time to time I find a strange problem.
I've just put one up tonight, that I know others have struggled with and failed to find a solution.
Maybe it's just a bug.

Anyway, thanks for being here.

  How to re-edit a text layer after saving xfc file and re-loading it?
Posted by: marco-gimp - 12-04-2016, 07:47 PM - Forum: General questions - Replies (6)

How to re-edit a text layer after saving xcf file and re-loading it?

This is a multi-layer xcf file with layers of text, and various layers of graphics.


Normally, selecting the text layer and text tool, allows the user to click on the text. The text box becomes active and adjustable, and text can be edited.

However, I have just re-loaded an xcf file - saved as - and found the text layers to be uneditable. 
The text border is dotted. 

Any attempt to click on it simply starts a new text layer.

It is as if the layer is locked. If so, how do I unlock it?
Note: the chain lock is not active.

I re-loaded the original xcf file.... it is the same.
It worked perfectly before saving and closing the file.

Is this a known bug?
It has happened to me before.
Also, after googling this problem, others have also experienced it, but I could find no satisfactory solution.

I have other xcf files that can be saved and the text re-edited.
Can anybody help?


GIMP 2.8.14
