python用法PyGame绘制图像并保存为图片文件的方法_ 本文实例讲解并描述了python用法PyGame绘制图像并保存为图片文件的方法分享给大家供大家参考具体实现方法如下： ''' pg_draw_circle_save101.py draw a blue solid circle on a white background save the drawing to an image file for result see tested with Python 2.7 and PyGame 1.9.2 by vegaseat 16may2021 ''' import pygame as pg # pygame uses (r, g, b) color tuples white = (255, 255, 255) blue = (0, 0, 255) width = 300 height = 300 # create the display window win = pg.display.set_mode((width, height)) # optional title bar caption pg.display.set_caption("Pygame draw circle and save") # default background is black, so make it white win.fill(white) # draw a blue circle # center coordinates (x, y) center = (width//2, height//2) radius = min(center) # width of 0 (default) fills the circle # otherwise it is thickness of outline width = 0 # draw.circle(Surface, color, pos, radius, width) pg.draw.circle(win, blue, center, radius, width) # now save the drawing # can save as .bmp .tga .png or .jpg fname = "circle_blue.png" pg.image.save(win, fname) print("file {} has been saved".format(fname)) # update the display window to show the drawing pg.display.flip() # event loop and exit conditions # (press escape key or click window title bar x to exit) while True: for event in pg.event.get(): if event.type == pg.QUIT: # most reliable exit on x click pg.quit() raise SystemExit elif event.type == pg.KEYDOWN: # optional exit with escape key if event.key == pg.K_ESCAPE: pg.quit() raise SystemExit 盼望本文所述对大家的Python程序设计有所关心。
