import cv2 def draw_text(input_path, output_path, text, position, font, font_scale, color, thickness): image = cv2.imread(input_path) if image is None: print("Error: Unable to open image file.") return cv2.putText(image, text, position, font, font_scale, color, thickness, cv2.LINE_AA) if cv2.imwrite(output_path, image): print(f"Image saved to {output_path}") cv2.imshow('Image Preview', cv2.imread(output_path)) cv2.waitKey(0) cv2.destroyAllWindows() else: print("Error: Unable to save image file.") draw_text('/home/jetson/opencv/images/yahboom_logo.png', \ '/home/jetson/opencv/images/yahboom_logo_text.png', \ 'Hello,OpenCV!', \ (550, 150), cv2.FONT_HERSHEY_SIMPLEX, 1, (0, 255, 0), 2)
