导语

转眼，八月十五中秋节即将到来，中秋节以月之圆兆人之团圆，

为寄托思念故乡，思念亲人之情，也是我国最具团圆意味的一个传统节日。

正文

基于pyqt5做的界面化中秋贺卡生成器。

（1）首先准备好相应的素材、如文字字体、贺卡背景等，大家可以随机制作。

（2）咳咳咳！之前有人说我文章前文太长，让我直接上代码。

class newyearCardGUI(QtWidgets.QWidget):    def __init__(self):        super(newyearCardGUI, self).__init__()        self.setFixedSize(600, 500)        self.setWindowTitle('中秋贺卡生成器-源码基地：#959755565#')        self.setWindowIcon(QIcon('icon/icon.png'))        self.grid = QGridLayout()        # 一些全局变量        self.card_image = None        self.font_size = 35        # 定义组件        # --Label        self.content_label = QLabel('内容路径:')        self.bg_label = QLabel('背景路径:')        self.font_label = QLabel('字体路径:')        self.fontcolor_label = QLabel('字体颜色:')        self.show_label = QLabel()        self.show_label.setScaledContents(True)        self.show_label.setMaximumSize(600, 300)        # --输入框        self.content_edit = QLineEdit()        self.content_edit.setText('contents/1.card')        self.bg_edit = QLineEdit()        self.bg_edit.setText('bgimages/1.png')        self.font_edit = QLineEdit()        self.font_edit.setText('fonts/font.TTF')        # --按钮        self.choose_content_button = QPushButton('选择路径')        self.choose_bg_button = QPushButton('选择路径')        self.choose_font_button = QPushButton('选择路径')        self.generate_button = QPushButton('生成贺卡')        self.save_button = QPushButton('保存贺卡')        # --下拉框        self.font_color_combobox = QComboBox()        for color in ['red', 'white', 'black', 'blue', 'yellow', 'green']:            self.font_color_combobox.addItem(color)        # 布局        self.grid.addWidget(self.show_label, 0, 0, 5, 5)        self.grid.addWidget(self.content_label, 5, 0, 1, 1)        self.grid.addWidget(self.content_edit, 5, 1, 1, 3)        self.grid.addWidget(self.choose_content_button, 5, 4, 1, 1)        self.grid.addWidget(self.bg_label, 6, 0, 1, 1)        self.grid.addWidget(self.bg_edit, 6, 1, 1, 3)        self.grid.addWidget(self.choose_bg_button, 6, 4, 1, 1)        self.grid.addWidget(self.font_label, 7, 0, 1, 1)        self.grid.addWidget(self.font_edit, 7, 1, 1, 3)        self.grid.addWidget(self.choose_font_button, 7, 4, 1, 1)        self.grid.addWidget(self.fontcolor_label, 8, 0, 1, 1)        self.grid.addWidget(self.font_color_combobox, 8, 1, 1, 1)        self.grid.addWidget(self.generate_button, 8, 3, 1, 1)        self.grid.addWidget(self.save_button, 8, 4, 1, 1)        self.setLayout(self.grid)        # 事件绑定        self.choose_content_button.clicked.connect(self.openContentFilepath)        self.choose_bg_button.clicked.connect(self.openBGFilepath)        self.choose_font_button.clicked.connect(self.openFontFilepath)        self.generate_button.clicked.connect(self.generate)        self.save_button.clicked.connect(self.save)        self.generate()

（2）生成贺卡。

 def generate(self):        # 检查路径是否存在        content_path = self.content_edit.text()        bg_path = self.bg_edit.text()        font_path = self.font_edit.text()        font_color = self.font_color_combobox.currentText()        if (not self.checkFilepath(content_path)) or (not self.checkFilepath(bg_path)) or (not self.checkFilepath(font_path)):            self.card_image = None            return False        # 写贺卡        contents = open(content_path, encoding='utf-8').read().split('\n')        font_card = ImageFont.truetype(font_path, self.font_size)        image = Image.open(bg_path).convert('RGB')        draw = ImageDraw.Draw(image)        draw.text((180, 30), contents[0], font=font_card, fill=font_color)        for idx, content in enumerate(contents[1: -1]):            draw.text((220, 40+(idx+1)*40), content, font=font_card, fill=font_color)        draw.text((180, 40+(idx+2)*40+10), contents[-1], font=font_card, fill=font_color)        # 显示        fp = io.BytesIO()        image.save(fp, 'BMP')        qtimg = QtGui.QImage()        qtimg.loadFromData(fp.getvalue(), 'BMP')        qtimg_pixmap = QtGui.QPixmap.fromImage(qtimg)        self.show_label.setPixmap(qtimg_pixmap)        self.card_image = image

（3）素材都是准备的多份，背景文字选取路径自己设置。

def openContentFilepath(self):        filepath = QFileDialog.getOpenFileName(self, "请选取贺卡内容文件", '.')        self.content_edit.setText(filepath[0])     def openBGFilepath(self):        filepath = QFileDialog.getOpenFileName(self, "请选取贺卡背景图片", '.')        self.bg_edit.setText(filepath[0])     def openFontFilepath(self):        filepath = QFileDialog.getOpenFileName(self, "请选取字体文件", '.')        self.font_edit.setText(filepath[0])

（4）生成的贺卡保存下来。

 def save(self):        filename = QFileDialog.getSaveFileName(self, '保存', './card.jpg', '所有文件(*)')        if filename[0] != '' and self.card_image:            self.card_image.save(filename[0])            QDialog().show()

好啦， 一张完整的贺卡显示就出来啦如下：
