定义每个功能函数
# 读取图片
def get_image():
img = cv2.imread(e1.get())
video_loop(dst=img)
return img
# 沿X轴翻转
def x_fig():
dst1 = cv2.flip(get_image(), 0)
video_loop(dst=dst1)
return dst1
# 沿Y轴翻转
def y_fig():
dst1 = cv2.flip(get_image(), 1)
video_loop(dst=dst1)
return dst1
# 同时沿X轴、Y轴翻转
def xy_fig():
dst1 = cv2.flip(get_image(), -1)
video_loop(dst=dst1)
return dst1
def f_exit(): # 退出按钮
exit()
# 平移照片
def move_img():
img = get_image()
height, width = img.shape[:2] # 读取原图像的长和宽
str1 = e3.get()
list1 = str1.split(',')
x = list1[0] # 自定义转换矩阵M的x轴移动值
y = list1[1] # 自定义转换矩阵M的y轴移动值
M = np.float32([[1, 0, x], [0, 1, y]]) # 构造转换矩阵M
move = cv2.warpAffine(img, M, (width, height)) # 平移映射
video_loop(move)
# 旋转图片
def xz():
img = get_image()
height, width = img.shape[:2] # 读取原图像的长和宽
M = cv2.getRotationMatrix2D((width / 2, height / 2), int(e2.get()), 0.6) # 以中心为原点,逆时针旋转45°,且缩小为原图的0.6倍,获得转移矩阵M
rotate = cv2.warpAffine(img, M, (width, height)) # 旋转映射
video_loop(rotate)
再图像化界面中显示照片的变化
def video_loop(dst):
cv2.waitKey(1)
cv2image = cv2.cvtColor(dst, cv2.COLOR_BGR2RGBA) # 转换颜色从BGR到RGBA
current_image = Image.fromarray(cv2image) # 将图像转换成Image对象
imgtk = ImageTk.PhotoImage(image=current_image)
panel.imgtk = imgtk
panel.config(image=imgtk)
return dst
创建一个窗口对象
window = tk.Tk()
window.title('图像的操作') # 窗口标题
window.geometry('1000x500') # 这里的乘是小x
输入图片文件的位置
# 在图形界面上设定标签,类似于一个提示窗口的作用
var = tk.StringVar()
l = tk.Label(window, text='输入图像位置', bg='pink', fg='white', font=('Arial', 12), width=50, height=2)
# 说明: bg为背景,fg为字体颜色,font为字体,width为长,height为高,这里的长和高是字符的长和高,比如height=2,就是标签有2个字符这么高
# 放置l控件
l.pack()
v1 = tk.StringVar()
e1 = tk.Entry(window, textvariable=v1, width=50)
e1.place(x=300, y=120 - 69)
为了提高用不的体验,对用户需要输入的文本框进行提示需要拓展一个小的功能
这个一段代码需要创建一个新的文件然后再次引用
from tkinter import *
class newEntry(Entry):
def __init__(self, master=None, placeholder="PLACEHOLDER", color="grey"):
super().__init__(master)
self.placeholder = placeholder
self.placeholder_color = color
self.default_fg_color = self["fg"]
self.bind("" , self.foc_in)
self.bind("" , self.foc_out)
self.put_placeholder()
def put_placeholder(self):
self.insert(0, self.placeholder)
self["fg"] = self.placeholder_color
def foc_in(self, *args):
if self["fg"] == self.placeholder_color:
self.delete("0", "end")
self["fg"] = self.default_fg_color
def foc_out(self, *args):
if not self.get():
self.put_placeholder()
设置键入平移的距离和旋转按钮
v2 = tk.StringVar()
e2 = newEntry(window, '输入旋转的度数')
e2.place(x=650, y=155)
# e2.insert(0, '输入旋转的度数')
# 在窗口界面设置放置Button按键并绑定处理函数
button_a = tk.Button(window, text='读取图片', font=('Arial', 12), width=10, height=1, command=get_image)
button_a.place(x=610, y=120 - 75)
设置键入旋转的度数和旋转按钮
v3 = tk.StringVar()
e3 = newEntry(window, "输入两个数值用英文逗号分开")
e3.place(x=650, y=215)
# e3.insert(0, "输入两个数值用英文逗号分开")
button_b = tk.Button(window, text='旋转', font=('Arial', 12), width=10, height=2, command=xz)
button_b.place(x=800, y=520 - 380)
设置沿着不同轴进行翻转
button_b = tk.Button(window, text='同时沿X轴、Y轴翻转', font=('Arial', 12), width=20, height=2, command=xy_fig)
button_b.place(x=750, y=520 - 260)
button_b = tk.Button(window, text='沿Y轴翻转', font=('Arial', 12), width=10, height=2, command=y_fig)
button_b.place(x=800, y=520 - 200)
button_b = tk.Button(window, text='沿X轴翻转', font=('Arial', 12), width=10, height=2, command=x_fig)
button_b.place(x=800, y=520 - 140)
退出按钮
button_b = tk.Button(window, text='退出', font=('Arial', 12), width=10, height=2, command=f_exit)
button_b.place(x=800, y=520 - 80)
图像模块的显示设置
panel = tk.Label(window, width=360, height=350) # 图像模块大小
panel.place(x=200, y=100) # 图像模块的位置
window.config(cursor="arrow")
# 窗口循环,用于显示
window.mainloop()
