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：
