PowerPoint 存成圖片檔的解析度調整

PowerPoint 很小氣,預設輸出圖片只有 1280x720
如果需要輸出高解析度的話必須要修改註冊機碼

微軟說明在此:
https://docs.microsoft.com/en-us/office/troubleshoot/powerpoint/change-export-slide-resolution

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\PowerPoint\Options

新增 DWORD (32-bit)
Name: ExportBitmapResolution
Value: 100 (Hex, 
Decimal = 256)

Value 100 差不多夠用,解析度表參考如下,是 10 進位 (Decimal)

Decimal valueFull-screen pixels
