火遍网络的python中秋节贺卡现在学还赶得上

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。

​

​佳节来临，我的侄女儿跟我打视频，说起了他们的中秋老师布置的小作业，每个孩子都会制作专属的中秋贺卡送给家人。

​​

​

果不其然，这又成了我的一个灵感，跟小侄女儿打完视频就开始了我的贺卡制作之路。

佳节来临，不如制作一份精美的手工贺卡，在中秋之夜送去真挚的祝福！跟着小编来学学吧~

正文

本文是基于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_b编程客栈utton.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：
