支持高DPI的录屏技术

高DPI导致的问题：

录制软件的识别的分辨率（1280*720）小于屏幕真实分辨率（1920*1080），导致只能录制屏幕的一部分。Gilisoft Screen Recorder 有客户反馈了这个问题。

 

解决办法：

DWORD oldp;
DWORD api_base = (DWORD)GetProcAddress(GetModuleHandleW(L"gdi32.dll"),"GetDeviceCaps");
VirtualProtect((void*)api_base,8, PAGE_EXECUTE_READWRITE, &oldp);
*(DWORD*)api_base = 0x60B8;
*(DWORD*)(api_base + 4) = 0x8C200;
VirtualProtect((void*)api_base,8, oldp, &oldp);
