Error when image dimension width> 65500 pixels

[ys_2k]

I tried to save a picture which the width is 70000pixels,
IrfanView will give me a prompt that

"JPG SAVE error!
Maximum supported image dimension is 65500pixels"

Is there anyway to overcome this problem?

thank you.

It is possible to create a PNG image that wide though unless your images has only a few colours you're going to run out of memory very easily with PNG format.

Hi ys_2k,

Hmmm ! 65000 is about 65535 (= 2^16 - 1) which is the greatest value for an unsigned short integer. Did you google to search if there is a size limitation for JPEG images?

Thanks for the reply.

Yup, i managed to save it as PNG format,
originally it is
BMP format = 91.9MB, after converted become
PNG = 32.7MB

I didn't able to get any related information from google.
Maybe 65535 is the maximum size for JPEG's width.
Thanks.
