基于PyQt5完成的PDF拆分功能基于PyQt5完成的PDF拆分功能

一、界面PdfC.ui可参考上文如何实现，程序代码如下：
二、main.py实现主要功能程序如下：
三、最后在主程序中加入以上子程序。
四、总结

PyQt是Qt框架的Python语言实现，是最强大的GUI库之一。PyQt提供了一个设计良好的窗口控件集合，具有更方便的操作性。学过VB的同学会知道，相比与VB的使用，在界面设计上元素更丰富。
本文就是基于PyQt5完成的PDF拆分功能，先看界面：

"开始拆分"))self.label_5.setText(_translate("PdfC", "输入页数(请勿输0)"))self.label_6.setText(_translate("PdfC", "到"))self.label_7.setText(_translate("PdfC", "PDF预览"))

二、main.py实现主要功能程序如下：

class pdcwindow(QtWidgets.QWidget,Ui_PdfC):def __init__(self):super(pdcwindow, self).__init__()self.setupUi(self)def re_back(self):self.close()def sctp(self):fileName, fileType = QtWidgets.QFileDialog.getOpenFileName(self, "选取文件", os.getcwd(),"自定义(*.pdf; *); ; All Files(*)")self.f = str(fileName)self.p, self.s =self.f.split(".")try:if self.s == "pdf":# 打开文件doc = fitz.open(self.f)# 读取一页 0代表第1页page_one = doc.loadPage(0)# 将第一页转换为Pixmappage_pixmap = page_one.getPixmap()# 将Pixmap转换为QImageimage_format = QImage.Format_RGBA8888 if page_pixmap.alpha else QImage.Format_RGB888page_image = QImage(page_pixmap.samples, page_pixmap.width, page_pixmap.height, page_pixmap.stride,image_format)#width = page_image.width()#height = page_image.height()# QImage 转为QPixmappix = QPixmap.fromImage(page_image)# 设置图片大小自适应标签self.label_4.setScaledContents(True)# 给标签设置图像self.label_4.setPixmap(pix)else:msg_box = QMessageBox(QMessageBox.Warning, "错误", "文件不是 pdf 文件，请重新选择！")msg_box.exec_()except Exception as e:passdef xzwj(self):pdf_file = PdfFileReader(self.f)output = PdfFileWriter()str1 = self.textEdit.toPlainText()num1 = int(str1)str2 = self.textEdit_2.toPlainText()num2 = int(str2)if num1 == num2:num1 = num1 - 1for i in range(num1, num2):output.addPage(pdf_file.getPage(i))# 写出pdfpdf_out = "{}_pdf拆分.{}".format(self.p,self.s)with open(pdf_out, 'ab') as out_pdf:output.write(out_pdf)root = tkinter.Tk()root.withdraw()tkinter.messagebox.showinfo("提示", "成功下载到源文件所在文件夹")

说明如下：
(1) def sctp(self): 其中的sctp为按钮的objectName属性名字；def xzwj(self):其中的xzwj为按钮的objectName属性名字；
(2) 可通过点击按钮实现本地文件上传；
fileName, fileType = QtWidgets. QFileDialog.getOpenFileName(self, "选取文件", os.getcwd(), "自定义(*.jpg; *.png; *.jpeg; *); ; All Files(*)")
(3) 增加了防错功能，当上传的文档格式不是pdf时，将不执行程序，同时提示错误；
(4) 将pdf第一页转为图片，并用label组件显示；
(5) 在def xzwj(self):程序中可实现按页数拆分pdf；

三、最后在主程序中加入以上子程序。

if __name__ =="__main__":import sysapp = QtWidgets.QApplication(sys.argv)win = mywindow()pc = pdcwindow()win.show()win.pdf_cf.clicked.connect(win.pic_main)win.pdf_cf.clicked.connect(pc.show)pc.Reback.clicked.connect(pc.re_back)pc.Reback.clicked.connect(win.show)pc.scwd.clicked.connect(pc.sctp)pc.xzwd.clicked.connect(pc.xzwj)sys.exit(app.exec_())

四、总结本文介绍的pdf拆分功能还有一些待完善地方，例如可增加预览功能，实现每页预览，以及如何实现多条件拆分。当然我们可以在后续阶段逐渐完善。
