You’ll see in this example the result of updating the color palette of an original color image by using CCTR color palette.

Original image	Output

from GameBEye.gbcamimage import gbcamimage
from GameBEye.gbcamcolors.gbcamcolors import GBColorPalettes
import cv2

# Path to the image
image_filepath = "images\\originalImage.png"
img = cv2.imread(image_filepath)

# Creation of an GCCamImage object
gb_img = gbcamimage.GBCamImage()
# Reading of the file
gb_img.read(image_filepath)

# Displaying the original image
original_title = "Original image with {} color palette".format(
    gb_img.color_palette.name
)
cv2.imshow(original_title, gb_img.data)
print("Original color palette : {}".format(gb_img.color_palette))

# Changing image color palette
gb_color_palette = GBColorPalettes.AZC
gb_img.change_color(color_palette=gb_color_palette)

# Displaying the colorized image
color_title = "Colorized image with {} color palette".format(
    gb_img.color_palette.name
)
cv2.imshow(color_title, gb_img.data)
print(
    "Colorized image color palette : {}\nRequired color palette : {}".format(
        gb_img.color_palette, gb_color_palette
    )
)

cv2.waitKey()
cv2.destroyWindow(original_title)
