Hello. I try to save bmp file that is big size (4096 x 153600) and mono. I can save it as "png", but I cannot save the big file as bmp. Let me know how to save the big file as "bmp"? Thank you.

opencv version, os, compiler ?

any chance, you're on a 32bit os, and that it is a memory problem ?

or that your disc cannot hold another 600mb image ? (that sounds very likely ..)

(i can't reproduce your problem on win64, 3.4-dev)

Thank you for your reply. I use 64 OS and OpenCV version is 3.40. I am sorry, I want to change my queston. I can save and read its big file, but its properties are not correct. If file size is less than 4096 x 117760, its properties are correct (Image view program can display its header information.

Is it possible to save your file in BMP ?
