    溫馨提示:易賢網(wǎng)小編為您整理了“python使用PyGame繪制圖像并保存為圖片文件的方法”,方便廣大網(wǎng)友查閱!

    本文實(shí)例講述了python使用PyGame繪制圖像并保存為圖片文件的方法。分享給大家供大家參考。具體實(shí)現(xiàn)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 16may2013

    '''

    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

    希望本文所述對(duì)大家的Python程序設(shè)計(jì)有所幫助。
