  Creating bump/displacement/spec maps and seemless texture tutorials needed
Posted by: Skullvapor - Today 20:04 - No Replies

So I posted this on another thread (The beginners one) and I posted this on yahoo answers and still have not gotten anything. I could really use some good tutorials for creating seamless textures and making them into bump/displacement/spec maps on gimp without expensive software like Pixplant. (Basically from scratch) I am a complete noob at textures but I have been using unity and blender for quite a while with some other stuff. Any good texturing tutorials, written or video, or even some advice will suffice.

  Building up an XCF from embedded XCFs
Posted by: kaladorn - Today 14:08 - Replies (4)

Here's my scenario:

Building a map for a space game. GIMP lets me do all the wonderful graphic work to make a usable map and it supports layering so I can crank out different views of the map. That's all awesome.

However, I have a bunch of sector maps saved as different XCFs. To make the maser map, to date I've been exporting views of the Sector Maps and bringing them in as layers on the master map. Works, but a bit a clunky to referesh ongoing as our game will progress.

Is there any way to build a GIMP image in the same fashion you'd build a master document built from subdocuments in a word processor? That is to say, can I import (but not by pulling in a set of Sector Map layer copies, but instead by pulling in a linked XCF sector map) the Sector Maps into a Master Map?

Concept: If it was possible to construct a Master Map out of sub-map files but have it so that when I edit something in the sub-map file, it shows on the master map or if I edit it on the master map, the sub-map file is updated, that would be really handy.

Is this sort of embedding (rather than importing) of XCFs within another XCF with a dynamic two-way update even feasible in GIMP?

I'm likely asking for something GIMP wasn't built for, but it would be kind of cool if it could support this kind of object-based visual construction.

Thanks in advance for any thoughts on whether this is feasible and if so how one goes about it.

  Paint dynamics horizon text?
Posted by: Capt Sam - Yesterday 11:11 - Replies (4)

[Image: Z9GP5jn.jpg]

My problem is the words "Pressure Velocity Direction . . . " are all horizontal now. They used to be vertical. This makes my Paint Dynamics editor panel much wider.

It there an easy fix for this that I am missing?

  auto colorize image in Gimp
Posted by: mathewbailey08 - Aug 22, 2016 11:54 - Replies (6)

I'm trying to figure out how how to use Python or Script-Fu in Gimp to automatically colorize a grayscale image in Gimp. First of all,I'm using a color wheel I found online http://docs-hoffmann.de/a3gencolorhigh.p...,-150,1168 which I then cropped to the square area around it. The next thing I want to do is to have the script first for example colorize the first pixel red or cyan at position 0,0 then the next pixel green or magenta at position ,01 then the next pixel blue or yellow at position 0,2,etc. & repeat the process automatically until the whole image is colored. Here is what I wrote while manually performing the process as follows:Manual Colorizing of Grayscale Images in GIMP REVISION 1

This text tutorial is being written as each step is being performed in GIMP.

Open original image of color wheel.
Make two duplicates
Close original image(discard changes)
Convert first duplicate to grayscale
Copy & paste grayscale image to second duplicate as new layer
Tool settings in GIMP as follows

Set threshold in Select by Color tool to 0.0
In Color Picker tool,check Use info window
In Pencil Tool,set Brush to 1.Pixel,set Size to 1.00

Colorzing grayscale image pixel by pixel

Open original grayscale image to colorize
Make duplicate of image & close original (discard changes)
Convert duplicate image to grayscale then to RGB
It is important to pay attention to the horizontal & vertical positions of each pixel
The numbers for example 0,0 are in the lower left bottom of image window next
to box that indicates px
For example, first number 0 indicates horizontal position of pixel,
while second 0 indicates vertical position of pixel
You will also need to use such position information when using the two color wheel images
Now let's start performing the process
For example if the RGB values of the first grayscale image pixel to colorize
is 128, the RGB value will be as follows:
Now for looking for the matching grayscale pixel in the grayscale image layer of the color wheel
as follows: Find the image layer of the grayscale(indicated by clipboard) color wheel & select it
for example Untitled 3.0 indicated by Clipboard in Layers-Gradients window.
Zoom in to 800% or more or use View,Zoom,8:1 or more
Move vertical slider on right edge of image window up
Select Color Picker tool & move it until example grayscale value is displayed
When example grayscale value is displayed,note vertical & horizontal
positions of pixel
(example 256,79)
Select Select by Color tool & click on the pixel to highlight it
Turn off eye icon on grayscale(clipboard) layer of wheel & select bottom layer to use it (highlighted in blue)
Select View,Zoom then Fit image in window
In the image to colorize,(not the grayscale or color images of the color wheel)
for example,the first pixel in the image to color after zooming in on the image to
800% or more would be red,second pixel would be green & third pixel would be blue
at upper left corner of window.
Now for the actions to perform with the color layer of the color wheel

Notice for example where the red portion & related is located on the wheel
Zoom in to 800% or more manually by selecting magnifier icon
With Color picker tool,select the example for red by clicking on the highlighted
pixel for it at the example positions 334,255
Switch back to the image to colorize & using Pencil tool,click on the pixel to color
You just colored the first pixel at position 0,0
However,the manual coloring process is time consuming & frustrating,so I'm trying
write a script or plugin to automate & speed up the process to make it faster & easier
One more thing the process can also be done the same but with using the cyan,magenta & yellow
& related portions of the color wheel. Photoshop & other programs however differ,make certain if they support scripts or plugins. I'll also be updating this topic with further updates on what I want this process to do

  Transferring Real Measurement to GIMP Image
Posted by: parmelbe - Aug 21, 2016 22:57 - Replies (2)

Hi, all, serious amateur here.

I've checked out the "GIMP inches vs. real life inches thread" and haven't been able to apply those solutions to my situation, so I think I need some more specific help.

Every time I try to measure a real-life object and recreate its dimensions on a GIMP image I end up way off. I'm working on designing a ground "foil" for a scale model airport and in order to show the positions of my buildings I need to measure what I have then create a filled-in selection in my image. I set my image resolution to 95ppi and have been measuring the buildings then multiplying the # of inches I need by 95. Every time I hold my building up to the screen to test the size my selection is too small. What am I doing wrong? Is it actually correct but my monitor resolution causes the discrepancy? If that's the case what is a good way to check my work? If anyone can spare the time to walk me through how to achieve what I need I'd really appreciate it.

Thanks for your help, I've been tearing my hair out here.

  Can I stretch an irregular selection to a rectangle?
Posted by: shortmort37 - Aug 21, 2016 22:45 - Replies (6)

I want to "normalize" photos of documents that, in addition to being somewhat trapezoidal because of the angle from which they were taken, have a bit of a "fisheye" effect. (I did not take the pictures!)

Given that the images are roughly rectangular - is there a GIMP feature that will resample an irregular selection and map it to a rectangular frame?

  Strange color error
Posted by: Befuddled - Aug 21, 2016 00:14 - Replies (1)

All right, I have a mystery here that's in need of some GIMP experts, and this looks like the place to ask. If you head over to Square Root of Minus Garfield, a webcomic project for remixing Garfield comics, you'll see this strip on the main page with a description that reads:

Quote:This strip was accidentally created when I was trying to make a SRoMG strip, but needed the word "sheep." I put this strip into GIMP to crop out the word "sheep," and when it came up, this is what I saw.

...I'm still not sure how it happened.

And on the forums, the guy who created it wrote:
Quote:I think I remember downloading the gif from ucomics and inflating it in GIMP. After cropping out the word "sheep," I think I saved the crop as a separate file. I had my other strip open (the one where Garfield is really fat and lying on the floor), which was also a gif, but downloaded from Garfield.com, and was going to plaster "sheep" on as another layer. The "sheep" and the area surrounding it was in a weird color. I went back and opened up the first strip and the same thing happened. This did not happen when I saved it to a jpeg, only gif and png. I ended using a different print in the strip from Garfield.com to fix it.

What I need to know is if anyone here can recreate this scenario and tell me what happened. I'm sure my friend would greatly appreciate an answer. Thanks in advance! :-)

  Suggestions to make a word appear tamperproof
Posted by: xrbbaker - Aug 16, 2016 18:31 - Replies (4)

Hello -

I'm an occasional GIMP user as well as Inkscape when that is more appropriate. I love GIMP but really have to re learn half of it every time I use it because I come back to it only once every 6 months or so...

I would like to take a word "Tamper-proof" and then make the word look like what it says. For example perhaps make the word 3-D and look like some metal was shrink-wrapped over top of it. Another idea would be to make the 3-D word look like it is made out of iron, with perhaps bolts on the edges, bolting the word down making it tamper proof. Maybe a key has it locked. Maybe a lock hangs off of it. You get the idea.

I was wondering if;
a) are there any readily available built in themes or modifications that can produce such an effect. I haven't found one, but I don't know every nook and cranny of the product.

b) if there aren't any readily available transformations, does anyone have any suggestions on how to approach this

c) if the approach to this is very complicated and beyond the skills of an advanced beginner, then I would appreciate that insight, as I could then try to come up with something else.

d) where could I find a Gimp expert for hire? If it would take me 20 hours and an expert 2 hours, I suspect I'd rather pay someone to do it!

Thank you for any advice given.

  Color to Alpha
Posted by: leonardfaraday15 - Aug 16, 2016 17:17 - Replies (2)

For the past week I've been trying to make the 'Color to Alpha' command work. When used exactly as described in the documentation, the command converts the entire image to alpha, not the color I select. This is what I get every single time I open any image on my computer.

If I open a black and white image, and select white, black will also be made alpha.

I press the control, and it presents what looks like an utterly simple interface. It allows me the chance to choose a color with the color select tool. I choose the color selector and click on the color I want to be alpha. That color does in fact change in the interface. Nonetheless, in the preview everything gets the checkerboard, and everything is turned to alpha.

I'm positive that somewhere in the program, some default is set that effects how great a variation that color select covers. I can't find it. I looked for a really long time, I don't know where it is.

Please do not tell me to read the manual. I really did because I hate coming to these forums. I'm not finding any answers in the manual.
