Thank you.
So its not question of image format. Its good to know.
I have tried- accoring to wiki´s "how to- liberaries- open cv"-- CB--Project--Set program arguments--lena.jpeg--ok, but it
doesnt work.
I tried also computer--system properties.-- system variables-- Path but it also doesnt work.
Have I forgotten anything?
Samples openCV, which use notebook camera and animations run in CodeBlocks normally, applications which use .jpeg end with message- image cannot be open.
P.
