问题
我可以用kivy中的Image()
模块加载图片。This是我如何安装kivy以便查看TIFF文件的。但是现在每次我加载一个TIFF图像,我都会收到一个接一个的弹出警告,打断程序。你知道吗
TIFFReadDirectory warning:
unknown field with tag 18246 (0x4746)
TIFFReadDirectory warning:
unknown field with tag 18249 (0x4749)
TIFFReadDirectory warning:
unknown field with tag 20752 (0x5110)
TIFFReadDirectory warning:
unknown field with tag 20753 (0x5111)
TIFFReadDirectory warning:
unknown field with tag 20754 (0x5112)
TIFFReadDirectory warning:
unknown field with tag 40092 (0x9c9c)
TIFFReadDirectory warning:
unknown field with tag 40093 (0x9c9d)
TIFFReadDirectory warning:
unknown field with tag 40094 (0x9c9e)
为了澄清,这些警告都不会出现在python日志中。这些都是在我的程序显示TIFF文件之前出现的单独警告框。我听说一个叫libtiff的库会引起这个问题。你知道吗
代码
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.clock import Clock
from kivy.uix.image import Image
class ContainerBox(BoxLayout):
def __init__(self, **kwargs):
super(ContainerBox, self).__init__(**kwargs)
self.orientation = 'vertical'
self.picture = Image(allow_stretch=True, source='..\pics\snorlax.tif')
Clock.schedule_once(lambda dt: self.add_widget(self.picture), timeout=0.1)
class SimpleImage(App):
def build(self):
return ContainerBox()
if __name__ == '__main__':
SimpleImage().run()

我的问题
是否可以抑制这些警告?我认为它们是由kivy调用的某个库生成的。它甚至可能是我无法编辑的预编译代码。
我花了很长时间用Kivy制作了一个复杂的用户界面。我真的不想放弃所有的工作。但我可能愿意把它移植到c++中,理论上我可以控制更多的代码。这是必要的还是可能的?你知道吗
在我的剧本开头,我加了
警告停止了。你知道吗
