This article will explain in detail how to use python to make Mid-Autumn Festival greeting cards. The content of the article is of high quality, so the editor will share it with you for reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Introduction

In a twinkling of an eye, the Mid-Autumn Festival is coming on August 15th, and the Mid-Autumn Festival symbolizes the reunion of people with the full moon.

It is also a traditional festival with the most meaning of reunion in our country to miss our hometown and relatives.

Interface Mid-Autumn Festival greeting card generator based on pyqt5.

(1) first of all, prepare the corresponding materials, such as text fonts, greeting card background, etc., you can make at random.

(2) ahem! Before someone said that the previous article of my article is too long, let me directly on the code.

Class newyearCardGUI (QtWidgets.QWidget): def _ _ init__ (self): super (newyearCardGUI, self). _ _ init__ () self.setFixedSize Self.setWindowTitle ('Mid-Autumn Festival greeting card generator-source base: # 959755565) self.setWindowIcon (QIcon (' icon/icon.png')) self.grid = QGridLayout () # some global variables self.card_image = None self.font_size = 35 # define component #-- Label self.content_label = QLabel ('content path:') self.bg_label = QLabel ('background path:') self.font_label = QLabel ('font path:') self.fontcolor_label = QLabel ('font color:') self.show_label = QLabel () self.show_label.setScaledContents (True) self.show_label.setMaximumSize Input box 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') #-- Button self.choose_content_button = QPushButton ('Select path') self.choose_bg_button = QPushButton ('Select path') self.choose_font_button = QPushButton ('Select path') self.generate_button = QPushButton ('generate greeting card') self.save_button = QPushButton ('Save greeting card') #-drop-down box self. Font_color_combobox = QComboBox () for color in ['red' 'white',' black', 'blue',' yellow', 'green']: self.font_color_combobox.addItem (color) # layout 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, 6,1,3) 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) # event binding 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) generate greeting cards.

Def generate (self): # check whether the path exists 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 # write greeting card 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) * 40mm 10), contents [- 1], font=font_card, fill=font_color) # shows 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) the material is prepared in multiple copies, and the background text selection path is set by yourself.

Def openContentFilepath (self): filepath = QFileDialog.getOpenFileName (self, "Please select the greeting card content file",'.) Self.content_edit.setText (filepath [0]) def openBGFilepath (self): filepath = QFileDialog.getOpenFileName (self, "Please select the background picture of the greeting card",'.) Self.bg_edit.setText (filepath [0]) def openFontFilepath (self): filepath = QFileDialog.getOpenFileName (self, "Please select font file",'.') Self.font_edit.setText (filepath [0])

(4) the generated greeting cards are preserved.

Def save (self): filename = QFileDialog.getSaveFileName (self, 'save','. / card.jpg', 'all files (*)) if filename [0]! =' 'and self.card_image: self.card_image.save (filename [0]) QDialog () .show ()

All right, a complete greeting card will appear as follows:

All right! The Mid-Autumn Festival greeting card generator is finished, it is not easy to make, the Mid-Autumn Festival is coming to an end.
