python游戏开发之视频转彩色字符动画
本文实例为大家分享了python视频转彩色字符动画的具体代码,供大家参考,具体内容如下
一、效果
原图:
转换后:
效果可通过代码开头几行的参数调节
二、代码
开头几行代码,自己看着调整,把效果调到最佳就ok。
依赖库:
pip install opencv-python
pip install pygame
代码:
import pygame import cv2 FONT_SIZE = 18 # 字体大小,可自行调整 WIN_SIZE = (1440, 1000) # 窗口大小,可自行调整 VIDEO_SIZE = (30, 30) # 视频大小,可自行调整 VIDEO_PATH = './cat.gif' # 视频文件(可以为常见的视频格式和gif) STR_TEXT = '假装失智' # 替换字符,可自定义,没有长度限制,但至少得有一个 def video2imgs(video_name, size): img_list = [] cap = cv2.VideoCapture(video_name) while cap.isOpened(): ret, frame = cap.read() if ret: img = cv2.resize(frame, size, interpolation=cv2.INTER_AREA) img_list.append(img) else: break cap.release() return img_list # 初始化pygame def main(): pygame.init() winSur = pygame.display.set_mode(WIN_SIZE) imgs = video2imgs(VIDEO_PATH, VIDEO_SIZE) btnFont = pygame.font.SysFont("fangsong", FONT_SIZE) btnFont.set_bold(True) # 生成surface sur_list = [] for img in imgs: height, width, color = img.shape surface = pygame.Surface(WIN_SIZE) a = 0 x, y = 0, 0 for row in range(height): x = 0 for col in range(width): # 获取当前像素RGB rgb = img[row][col] rgb[0], rgb[2] = rgb[2], rgb[0] text_texture = btnFont.render(STR_TEXT[a], True, rgb) a = a + 1 a = a % len(STR_TEXT) surface.blit(text_texture, (x, y)) x = x + FONT_SIZE y = y + FONT_SIZE sur_list.append(surface) # 游戏主循环 current_frame = 0 while True: for event in pygame.event.get(): if event.type == pygame.QUIT: exit() pygame.time.delay(int(1000 / 24)) winSur.fill((0, 0, 0)) winSur.blit(sur_list[current_frame], [0, 0]) current_frame += 1 current_frame %= len(sur_list) # 刷新界面 pygame.display.flip() if __name__ == '__main__': main()
