Posted by: T-TaaN - 06-24-2024, 08:48 AM - Forum: General questions - Replies (2)

I have a parallelepiped/cube baked in 2d image and I need to rotate it. Is there an option or a plugin, that let me select all 6 visible edges and make rotation of it as it were 3d object?

  using Photolab - Batch corrections - Curve
Posted by: arodri - 06-23-2024, 09:28 AM - Forum: General questions - Replies (15)

Good morning

I'm very new using Gimp, so I'm here to ask for your help, for a situation that I'll explain below:

My system - Windows XP SP3

Gimp version - 2.8.22

The situation:

I'm a collector of comic strips from newspapers, and these strips are often not of great quality, which is why I recently discovered Gimp, and more specifically the "Colors - Curves" option, which helped me a lot in cleaning and improving the images (one by one).

Since I often have to improve hundreds of images, I looked for a way to do it in batch processing and discovered "Photolab - Batch corrections - Curve".

Even though I followed the steps explained
1. carry out a procedure on an image
2. Export the definitions of that procedure to an external file


When using "Photolab - Batch corrections - Curve" I invariably get the message, which I attach
I tried it several times, but the situation remains.

As I have a laptop with Windows 7, I thought, maybe because XP is old it doesn't work, but the result is the same.

Could you help me?
My thanks in advance.
Arodri

  Trying my hand at Processing, the "Logo" for grown-ups
Posted by: Ofnuts - 06-22-2024, 12:32 PM - Forum: Gallery - Replies (21)

This processing.

   

Code isn't too complicated
Code:
[align=left]float startAngle=0;

void setup() {
  size(800,800);
  colorMode(HSB,360,100,100);
}

void drawSquare(float radius,float angle,float size) {
    float squareX=width/2+radius*cos(angle);
    float squareY=height/2+radius*sin(angle);
    pushMatrix();
    translate(squareX,squareY);
    rotate(angle+radians(5)); // Compensate "slope"of log spiral
    rect(0,0,size,size,size/8);
    popMatrix();
}

void draw() {
  noStroke();
  background(255);
  float radius=height/2-50.;
  float size=radius/10;
  float squareAngle=startAngle;
  float shrink=.9975;
  float shiftAngle=7;
  float hue=360;
  float brightness=100;
  while (radius > 2) {
    fill(hue,80,brightness);
    drawSquare(radius,radians(squareAngle),size);
    radius*=shrink;
    size*=shrink;
    squareAngle+=shiftAngle;
    hue*=shrink;
    brightness*=shrink;
  }  
  startAngle-=.5; // For animation
}

  Annunciation
Posted by: MJ Barmish - 06-20-2024, 05:06 PM - Forum: Gallery - Replies (1)

Hi, all. Here is my latest creation, using the puzzle and porcelain process, entitled "Annunciation" (published on my site https://mjbarmish.fr). In a while, I may post his original photo, as I did of other images ; but I hesitate, because I like it very much for its spiritual atmosphere and I fear trivializing it by showing where it comes from Blush .

  How to stop GIMP snaaping to desktop title bar in Mac os 10.15
Posted by: Ranger1951 - 06-19-2024, 04:08 AM - Forum: General questions - Replies (5)

I am running GIMP 2.10.38 on iMac running OS 10.15 Catalina. When opened, GIMP work space windows keeps 'snapping' to the desktop title bar. Thus hiding all other open windows / apps.

Can anyone suggest a fix, please? Thank you.

  The Gimp is a superb option for image editing...
Posted by: SiriusA - 06-18-2024, 11:34 AM - Forum: General questions - Replies (10)

But I have one question..

Where's the shape tool?

Is there some kind of a legal limitation for this to exist?

I mean, I would go to the left bar and I want to select a tool to use..

I might want to make a 5 pointed star for example, of any size, very quick and easy..

Or a circle, or a square, or triangle..

Am I just being stupid here? Crazy? Or why can't I find it?

BTW no I'm not such a big fan of having to do these sorts of things using a select tool, either.


I think there ought to be a line tool, also..

I mean SURE, I CAN hold the alt-key down, but to an average user, it sure is difficult to find.

Maybe it would be appropriate to include it in the same category as shapes?

A line is a shape.

  23 minutes and 23 seconds
Posted by: PixLab - 06-15-2024, 05:27 AM - Forum: Watercooler - Replies (8)

Although, it's not always red, for instance on my distro/theme it's black





No I did not wait 23 minutes and 23 seconds Tongue , I opened GIMP in another Workspace, put the timer (MATE timer applet) at 23 minutes and 5 seconds, continue my things on the other Workspace, then when the timer finished a notification appeared on my screen, thus I just have to switch Workspace to see it Big Grin

  How can this be an unknown file type?
Posted by: ajax - 06-13-2024, 09:22 PM - Forum: General questions - Replies (10)

Just received a very perplexing error message indicated by screenshot that follows:

   

Just to be sure that message results when trying to export image files of any normal type (i.e., I've tried .tif, .jpg, & .png) as shown by the example that follows:

   

This is happening when running GIMP Version 2.10.38, which was newly obtained, on Windows.  I definitely need some help figuring out what is going on here.

  Size problem in saved tif image
Posted by: MarcoCarta - 06-11-2024, 07:49 PM - Forum: General questions - Replies (7)

Hi all,
I face a problem in saving a tif image.
What I'm doing :
I'm editing a 3600x3600 16bits integer grayscale geotiff with 1 layer.
When I save it and reopen it with the Gimp 2.10, the image is 3602X3600 px and the layer have a 2px left offset.
Despite of numerous attempts to correct size and layer position, when I save it the same thing append.
Am I missing something obvious here ?
thanks for reading
