python - pywin32:获取系统调色板条目

Question

pywin32 是否有相当于 GetSystemPaletteEntries 的功能？如果没有，我该如何调用此电话？

Answer 1

这有效，返回一个与 PIL 兼容的调色板:

import ctypes, win32gui
def getPalette(hwnd):
    #hwnd = win32gui.GetDesktopWindow() #if you want desktop window palette?

    hwndDC = win32gui.GetWindowDC(hwnd)

    buff = ctypes.c_buffer("0"*(256*4)) #R, G, B, and flags
    ctypes.windll.gdi32.GetSystemPaletteEntries(hwndDC, 0, 256, buff)

    win32gui.ReleaseDC(hwnd, hwndDC)

    #ignore every 4th entry which is the flags
    res = [ord(x) for i,x in enumerate(buff) if i%4 != 3]
    return res
