JPEG Saver 5

« Return to JPEG Saver page

JPEG Saver 4.0 replaced the DirectX 3/DirectDraw transitions used in JPEG Saver 3.x with DirectX 9 and Direct3D transitions. JPEG Saver 5 updated the graphics code again, this time using DirectX 11.

This means that JPEG Saver 5 doesn't need to install any extra DirectX libraries, as DirectX 11 has been installed with the operating system since Windows 7. DirectX 11 also means JPEG Saver can display transitions on any machine that supports the WARP device, which does all the stuff that would usually be handled by a graphics card in software.
