基於Python製作一款螢幕顏色提取器
2022-03-02 13:01:06
1.使用效果
如下面動圖所示，點選取色按鈕後，將滑鼠移動到想要取色的位置，等待兩秒即可取色：
點選save color按鈕可以將顏色儲存到color library區域，同時如圖所示，
! ! ! !紅框內所有的方形元件其實都是按鈕，點選後能獲得顏色資訊 ! ! ! !
資訊格式為：(173, 189, 163) #ADBDA3 (48, 35, 189)
2.所需python包
- PySide2
- pyautogui
- pyperclip
- ctypes
from PySide2.QtWidgets import QApplication,QWidget,QLineEdit
from PySide2.QtWidgets import QLabel,QPushButton
from PySide2.QtGui import QIcon,QFont
from PySide2.QtCore import Qt
import sys
sys.path.append("...")
import time
import pyautogui as pag
import pyperclip
from ctypes import *
3.python小技巧
3.1控制元件陣列
和matlab一樣，python得控制元件也能構成陣列，例如我在建立小顏色框時，是這麼寫的：
# 儲存顏色框
for i in range(0,2):
for j in range(0,10):
storeColorBox=QPushButton(self)
storeColorBox.setGeometry((0.04+0.093*j)*Width,(0.475+0.07*i)*Height,0.08*Width,0.06*Height)
storeColorBox.setStyleSheet(self.SS_Color_Box)
storeColorBox.setProperty("storeId",i*10+j)
storeColorBox.setProperty("Color",'#FFFFFF')
storeColorBox.clicked.connect(self.selectedStore)
self.storeList.append(storeColorBox)
就是將各個顏色框存入了self.storeList這個陣列，
想要例如想要呼叫第i個顏色框，就可以這麼寫：
storeBox=self.storeList[i]
3.2將控制元件作為屬性
將控制元件控制元件作為屬性賦給另一個控制元件
因為我們想要點選左側標籤時獲得對應文字方塊內資訊：
就可以這麼寫（舉個例子）：
# 建立文字方塊
self.CB1=QLineEdit(self)
self.CB1.setText("255,255,255")
self.CB1.move(0.62*Width,0.03*Height)
self.CB1.resize(0.35*Width,0.065*Height)
self.CB1.setFont(qf)
self.CB1.setStyleSheet(self.SS_Inf_Box)
# 建立標籤
self.CL1=QPushButton(self)
self.CL1.setGeometry(0.448*Width,0.025*Height,0.14*Width,0.075*Height)
self.CL1.setStyleSheet(self.SS_Inf_Label)
self.CL1.setText("RGB")
self.CL1.setFont(qf)
self.CL1.setProperty('Children',self.CB1) # 把控制元件作為屬性
self.CL1.clicked.connect(self.copyInf)# 與回撥函數相連
然後我的回撥函數是這樣寫的：
def copyInf(self):
infLabel=self.sender()
infBox=infLabel.property('Children') # 通過找到屬性找到對應控制元件
pyperclip.copy(infBox.text())
3.3怎樣重設控制元件顏色
還是通過setStyleSheet設定嗷，不過把字串部分應該放顏色的部分換成了要重設的顏色：
self.mainBox.setStyleSheet("QPushButton{background:"+self.curColor_HEX
+";border: 3px solid rgb(150,150,150);border-radius:8px}")
3.4一些用到的字串操作
字串字母大寫
STR=STR.upper()
字串去掉空格
例如把(10, 50, 255)變為(10,50,255)
STR=STR.replace(" ", "")
字串去掉兩頭括號
例如把(10,50,255)變為10,50,255
STR=STR[1:-1]
3.5滑鼠位置畫素顏色
如何獲得當前滑鼠位置畫素顏色
import pyautogui as pag
from ctypes import *
x,y=pag.position()
RGB=get_color(x,y)
# 獲取x,y位置畫素顏色
def get_color(x, y):
gdi32 = windll.gdi32
user32 = windll.user32
hdc = user32.GetDC(None) # 獲取顏色值
pixel = gdi32.GetPixel(hdc, x, y) # 提取RGB值
r = pixel & 0x0000ff
g = (pixel & 0x00ff00) >> 8
b = pixel >> 16
return [r, g, b]
3.6視窗始終置頂
self.setWindowFlags(Qt.WindowStaysOnTopHint)
3.7文字方塊不允許編輯但允許複製
用setFocusPolicy(Qt.NoFocus)，例如程式中：
self.CB1.setFocusPolicy(Qt.NoFocus) self.CB2.setFocusPolicy(Qt.NoFocus) self.CB3.setFocusPolicy(Qt.NoFocus)
4.完整程式碼
from PySide2.QtWidgets import QApplication,QWidget,QLineEdit
from PySide2.QtWidgets import QLabel,QPushButton
from PySide2.QtGui import QIcon,QFont
from PySide2.QtCore import Qt

sys.path.append("...")

r = pixel & 0x0000ff
g = (pixel & 0x00ff00) >> 8
b = pixel >> 16

# RGB轉HEX

color = "#"
color += str(hex(r)).replace('x','0')[-2:]

h = ((g-b)/m)*60
