每次我調(diào)用 Convert() 或 send() 函數(shù)時(shí)，Python 代碼都會(huì)維護(hù)我在列表中打印的徽章。因此，每次我嘗試打印新徽章時(shí)，它都會(huì)首先打印所有舊徽章。在我執(zhí)行 Convert() 和 send() 命令進(jìn)行打印后，任何人都可以看到如何從列表中刪除徽章圖像嗎？這是代碼：import pygameimport timefrom PIL import Imagefrom brother_ql.conversion import convertfrom brother_ql.backends.helpers import sendfrom brother_ql.raster import BrotherQLRasterfrom brother_ql.backends import backend_factory, guess_backend######################################################################################################## Test QR-800 Printer###################################################################################################### Here I just get two images each of size 1044x696image1 = Image.open('RedBlack1_1044x696.png')image2 = Image.open('RedBlack2_1044x696.png')backend = 'linux_kernel'? ? # 'pyusb', 'linux_kernel', 'network'model = 'QL-800' # your printer model.printer = '/dev/usb/lp0'? ??qlr = BrotherQLRaster(model)qlr.exception_on_warning = Truebadge = convert(? ? qlr=qlr,?? ? images=[image1],? ? #?
