第基于PyQt5實現(xiàn)圖轉(zhuǎn)文功能(示例代碼)目錄一、界面PicZ.ui可參考之前的文章如何實現(xiàn)，程序代碼如下：二、main.py實現(xiàn)主要功能程序如下：三、最后在主程序中加入以上子程序。四、總結(jié)PyQt是Qt框架的Python語言實現(xiàn)，是最強大的GUI庫之一。PyQt提供了一個設(shè)計良好的窗口控件集合，具有更方便的操作性。學(xué)過VB的同學(xué)會知道，相比與VB的使用，在界面設(shè)計上元素更豐富。

本文就是基于PyQt5完成的圖轉(zhuǎn)文功能，先看界面：

一、界面PicZ.ui可參考之前的文章如何實現(xiàn)，程序代碼如下：

fromPyQt5importQtCore,QtGui,QtWidgets

importbase64

importos

fromreturn_pngimportimgasretu#引入img變量，賦別名為pdf_cf

classUi_PicZ(object):

defsetupUi(self,PicZ):

tmp=open('return.png','wb')#創(chuàng)建臨時的文件

tmp.write(base64.b64decode(retu))#把這個one圖片解碼出來，寫入文件中去。

tmp.close()

PicZ.setObjectName("PicZ")

PicZ.resize(1400,814)

PicZ.setMinimumSize(QtCore.QSize(1400,814))

self.close()

defsctp(self):
