I tried to create image dynamically and save it as .jpg image.

func _ready():
    var user_data_dir = OS.get_user_data_dir()
    print("User data directory:", user_data_dir)

    # Create a new image with specified width, height, and format
    var image = Image.new()
    image.create(256, 256, false, Image.FORMAT_RGB8)  # Creating a 256x256 image with RGB format
    
    # Fill the image with black
    image.fill(Color.BLACK)  # Fill the entire image with black color
    
    # Check if the image is empty (filled it with black); i don't think this is necessary but just checking
    var is_empty = true
    for y in range(image.get_height()):
        for x in range(image.get_width()):
            var pixel_color = image.get_pixel(x, y)
            if pixel_color != Color.TRANSPARENT:  # Check against black color with transparent
                is_empty = false
                break
        if not is_empty:
            break

    if is_empty:
        print("The image is empty.")
    else:
        print("The image is not empty.")

    # Save the image as a JPG file
    var file_path_jpg = user_data_dir + "/black_image2.jpg"
    var result_jpg = image.save_jpg(file_path_jpg)

    if result_jpg == OK:
        print("JPG saved successfully at: ", file_path_jpg)
    else:
        print("Failed to save JPG. Error code: ", str(result_jpg))

    # Verify if the file exists
    var jpg_exists = FileAccess.file_exists(file_path_jpg)
    print("JPG exists: ", str(jpg_exists))

Output Log:
User data directory:/Users/xxxx/Library/Application Support/Godot/app_userdata/game
The image is empty.
Failed to save JPG. Error code: 31
JPG exists: true

even thought file created its empty.

I tried to create an RGB8 image, fill it with color, and save it. But for some reason, the saved file is empty. Any idea why this is happening?

Note: I’ve been learning Godot for the past two weeks after switching from Unity, so if this is a newbie question, please bear with me. Thanks!

I also tried to save the png file it didn’t even create the png file but i tried with .jpg it created file but with empty data. All the code i have written is in detail section and output log.

I want to create image, write something in image and save that image that’s it.
