delphi – 我如何临时加载字体?

我需要在我的程序中临时加载一些字体.最好从dll资源文件.
最佳答案
这里是Delphi版本:

procedure LoadFontFromDll(const DllName, FontName: PWideChar);
var
  DllHandle: HMODULE;
  ResHandle: HRSRC;
  ResSize, NbFontAdded: Cardinal;
  ResAddr: HGLOBAL;
begin
  DllHandle := LoadLibrary(DllName);
  if DllHandle = 0 then
    RaiseLastOSError;
  ResHandle := FindResource(DllHandle, FontName, RT_FONT);
  if ResHandle = 0 then
    RaiseLastOSError;
  ResAddr := LoadResource(DllHandle, ResHandle);
  if ResAddr = 0 then
    RaiseLastOSError;
  ResSize := SizeOfResource(DllHandle, ResHandle);
  if ResSize = 0 then
    RaiseLastOSError;
  if 0 = AddFontMemResourceEx(Pointer(ResAddr), ResSize, nil, @NbFontAdded) then
    RaiseLastOSError;
end;

被使用像:

var
  FontName: PChar;
  FontHandle: THandle;
...
  FontName := 'DEJAVUSANS';
  LoadFontFromDll('Project1.dll' , FontName);
  FontHandle := CreateFont(0, 0, 0, 0, FW_NORMAL, 0, 0, 0, DEFAULT_CHARSET,
    OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, DEFAULT_PITCH,
    FontName);
  if FontHandle = 0 then
    RaiseLastOSError;
