PIL: Pillow Image.fromarray()

## DEPTH

import numpy as np
from PIL import Image

# Create a 2D NumPy array
gray_array = np.random.randint(0, 255, (224, 224), dtype=np.uint8)
img = Image.fromarray(gray_array)
img.show()

## RGB
rgb_array = np.random.randint(0, 255, (224, 224, 3), dtype=np.uint8)
img = Image.fromarray(rgb_array)
img.show()


## SET THE MODE 

rgba_array = np.random.randint(0, 255, (224, 224, 4), dtype=np.uint8)
img = Image.fromarray(rgba_array, mode='RGBA')
img.show()



#如果你的数组是 (224, 224, 4) （具有 4 个通道的深度图像），并且您想在 RGB 中使用它

import numpy as np
from PIL import Image

# Example depth array
depth_array = np.random.randint(0, 255, (224, 224, 4), dtype=np.uint8)

# Drop the alpha channel (use only the first three channels)
depth_rgb = depth_array[:, :, :3]

# Convert to PIL Image
img = Image.fromarray(depth_rgb)
img.show()


##如果你的数组是 (224, 224, 3): 

img = Image.fromarray(arr)
img.show()
