How to create image and save

Godot Version

Godot 4.2.2

OS: Mac 14.5 (23F79)
Chip: Apple M2 Pro


I tried to dynamically create image and save to jpg

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.create(256, 256, false, Image.FORMAT_RGB8)  # Creating a 256x256 image with RGB format
	# Fill the image with black
	image.fill(Color.BLUE)  # Fill the entire image with black color
	image.fill_rect(Rect2(0, 0, 20, 20), Color.RED)
	# Check if the image is empty (filled it with black)
	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(0, 0, 0, 1):  # Check against black color with alpha 1
				is_empty = false
		if not is_empty:

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

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

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

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

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

Its not working why?
I tried to create image format RGB8, fill with color and save that image that’s it why the image is empty and that file is saved but file is empty.

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 figure out the problem. Problem was use
Image.Create(256, 256, false, Image.FORMAT_RGB8)
rather than

var image =
image.create(256, 256, false, Image.FORMAT_RGB8)
