[英]Python screenshot to base64
Here is the way I take screenshots: 这是我截图的方式:
import wx
app = wx.App(False)
s = wx.ScreenDC()
w, h = s.Size.Get()
b = wx.EmptyBitmap(w, h)
m = wx.MemoryDCFromDC(s)
m.SelectObject(b)
m.Blit(0, 0, w, h, s, 0, 0)
m.SelectObject(wx.NullBitmap)
b.SaveFile("hey.png", wx.BITMAP_TYPE_PNG)
I don't want to save the screenshot as an image file "hey.png", I want it as base64 string. 我不想将屏幕截图另存为图像文件“ hey.png”,而是将其保存为base64字符串。
My final purpose is just to print the base64 string, then I want to put it manually in html code , here: 我的最终目的只是打印base64字符串,然后我想在html代码中手动将其放在此处:
<img src="data:image/png;base64,here" />
How can I do that? 我怎样才能做到这一点? Thanks in advance. 提前致谢。
You have to somehow get the bytes of that file. 您必须以某种方式获取该文件的字节。 This can be done two ways: 这可以通过两种方式完成:
For the actual encoding, you can use the built in base64 API. 对于实际的编码,您可以使用内置的base64 API。 Note that I linked to the Python 2 wiki instead of the Python 3 wiki, since to my knowledge wxPython is only available for python 2. 请注意,我链接到Python 2 Wiki而不是Python 3 Wiki,因为据我所知wxPython仅适用于python 2。
