什么是一个完整的例子，从无到有在内存中的位图结束，打开一个特定的.ttf文件，并使用该字体，使用本机Windows API呈现一些文本？ 我目前正在通过Windows API，所以这是我和其他的计算器之间的比赛。
完成并完成渲染字体（需要PyWin32）：
import ctypes import struct import win32con import win32gui import win32ui from PIL import Image def RGB(r, g, b): return r | (g << 8) | (b << 16) def native_bmp_to_pil(hdc, bitmap_handle, width, height): bmpheader = struct.pack("LHHHH", struct.calcsize("LHHHH"), width, height, 1, 24) #w,h, planes=1, bitcount) c_bmpheader = ctypes.c_buffer(bmpheader) #3 bytes per pixel, pad lines to 4 bytes c_bits = ctypes.c_buffer(" " * (height * ((width*3 + 3) & -4))) res = ctypes.windll.gdi32.GetDIBits( hdc, bitmap_handle, 0, height, c_bits, c_bmpheader, win32con.DIB_RGB_COLORS) if not res: raise IOError("native_bmp_to_pil failed: GetDIBits") im = Image.frombuffer( "RGB", (width, height), c_bits, "raw", "BGR", (width*3 + 3) & -4, -1) return im class Win32Font: def __init__(self, name, height, weight=win32con.FW_NORMAL, italic=False, underline=False): self.font = win32ui.CreateFont({ 'name': name, 'height': height, 'weight': weight, 'italic': italic, 'underline': underline}) #create a compatible DC we can use to draw: self.desktopHwnd = win32gui.GetDesktopWindow() self.desktopDC = win32gui.GetWindowDC(self.desktopHwnd) self.mfcDC = win32ui.CreateDCFromHandle(self.desktopDC) self.drawDC = self.mfcDC.CreateCompatibleDC() #initialize it self.drawDC.SelectObject(self.font) def renderText(self, text): """render text to a PIL image using the windows API.""" self.drawDC.SetTextColor(RGB(255,0,0)) #create the compatible bitmap: w,h = self.drawDC.GetTextExtent(text) saveBitMap = win32ui.CreateBitmap() saveBitMap.CreateCompatibleBitmap(self.mfcDC, w, h) self.drawDC.SelectObject(saveBitMap) #draw it self.drawDC.DrawText(text, (0, 0, w, h), win32con.DT_LEFT) #convert to PIL image im = native_bmp_to_pil(self.drawDC.GetSafeHdc(), saveBitMap.GetHandle(), w, h) #clean-up win32gui.DeleteObject(saveBitMap.GetHandle()) return im def __del__(self): self.mfcDC.DeleteDC() self.drawDC.DeleteDC() win32gui.ReleaseDC(self.desktopHwnd, self.desktopDC) win32gui.DeleteObject(self.font.GetSafeHandle()) def __del__(self): win32gui.DeleteObject(self.font.GetSafeHandle())
用法：
>>> f = Win32Font("Arial", 15) >>> im = f.renderText("this is just a test") >>> im.save("c:/hope.png")
结果：

辉煌！！！
为了呈现一个特定的.ttf文件，我需要挖掘更多。
更新：更新来计算bmp大小：
