.tga PImage flips y axis after save() and load()

Created by: Sebastian5

Description

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.

Beginne mit den Pfaden von PImage.save() und loadImage(), die an der Verarbeitung von .tga beteiligt sind, und führe dann die bereitgestellte 5×5-Reproduktion unter Processing 4.3 aus. Verfolge, ob das Speichern oder Laden die vertikale Pixelreihenfolge verändert; abgeschlossen ist es, wenn der rote Pixel nach dem Speichern und Laden der TGA oben links bleibt.
