Delphix provides a high-performance timer tdxtimer, which is basically the same as timer. When we use timer, we seldom set interval to below 50 (this should be the limit of its accuracy );You can use tdxtimer to set interval to 0, which means

It is known that the image formats supported by GDI + are BMP, JPEG, GIF, Tiff, PNG, ICO, WMF, and EMF. The tgpgraphics. drawimage function has too many reloads. Column them together: Function drawimage (image: tgpimage; const
