ONLY when pixels are saved ( PImage.save() ) as .tga and loaded again ( loadImage() ) they are fliped on the y axis.
Expected Behavior
That the image doesnt flip.
The demo code should show the red dot in the top left corner, not the bottom left.
Current Behavior
It is unclear whether the PImage.save() or loadImage() function is the root of the bug.
The Problem does NOT occur when:
If you save and image as .tga and open it with Paint.net: looks correct in Paint.net, not flipped
If you load an .tga created from Paint.net: looks correct in Processing, not flipped
But for .tga images that were PImage.save() and loadImage(). It flipps the pixels. It is very strange
Steps to Reproduce
PImage img1 = createImage(5, 5, RGB);
img1.pixels[0] = color(255,0,0); // left top corner must be red
img1.updatePixels();
img1.save("img.tga");
PImage img2 = loadImage("img.tga"); // comment out after using Paint.net to re-save image non corrupt
image(img2,0,0, width, height);
Your Environment
Processing version: 4.3
Operating System and OS version: Windows 10 Pro 22H2
Other information: AMD GPU Andrenail 23.12.1, Intel CPU
Possible Causes / Solutions
Maybe there is file desciptor flag to flip an image in the y axis.
