Is there any limitation for Max size of the output image of JPEG using IPP

[Sathish_S_]

Hello Everyone,

I am doing the JPEG encoding using Intel IPP libs. Everything is looking fine but I am encoding the 70000X70000 image , the output JPEG file is showing 4464X4464 . I ecoded the 50000X50000 image and the output JPEG file is showing correctly as 50000X50000 . I am not sure why 70000X70000 file convrted to 4464X4464. Is there any limitation for JPEG encoding?.

could anyone comment.

Regards,

Sathish,

that is due to 16-bit limit for variables representing image width and height in JPEG specification

Hello Vladimir,

That means, The maximum size of the JPEG file  we can create is 65535X65535. This, we can say it as a limitation.

Is it correct?.Please confirm.

Sathish,

strictly speaking it is limitation for one jpeg frame. Videly known jpeg jfif file format can contain only single frame for sequential coding process, and so, yet it is limitation for JFIF file format for encoded image.
