Software - emWin Graphic Library V1.0,in the document "UM03001_emWin5.pdf " on page #736-737 ,please find the image formats supported by emWin.
Thank you for your answer. I took a look, but that is not what I was asking.
I was asking if the IMAGE and SPINBOX widgets are supported on this version of the library.
No, these widgets are not supported in emwin5.02.
