I note that the pixel sizes configurable for 2D Surface image output increment in units of 8 pixels. I suspected this may have been an issue why I have not been able to get JPG format output files of my 2D Surface display. As I understand valid JPG file structure, the image size should be a multiple of 16 pixels in both directions when 4:2:0 chroma subsampling is used for a colour image, dictated by MCU block size. I have not had any problems with the PNG output format. What chroma subsampling method is used for the JPG files created by QfFuzzylite, please? Setting image size to multiples of 16 in both directions did not let me write JPG output format.
Has anyone else experienced problems trying to write JPG output files? What drove your choice of an 8 pixel increment, please? Are any other system dll files needed to write JPG output files on a Windows system? What about for LINUX?
