Hi all, It is quite funny I couldn't locate the syntax example on delay for opencv. For c++ normally the syntax would be delay_ms(200) and the coding will wait for 200ms before proceed to the next syntax.
Can anyone please help to direct me to the syntax.
Appreciate on everyone response. Thanks Zamani
Working C++ functions for both Windows and Linux. However do include the correct header files! Else it will never work.
#if defined(__WIN32__) || defined(_WIN32) || defined(WIN32) || defined(__WINDOWS__) || defined(__TOS_WIN__)
#include <windows.h>
inline void delay( unsigned long ms )
{
Sleep( ms );
}
#else /* presume POSIX */
#include <unistd.h>
inline void delay( unsigned long ms )
{
usleep( ms * 1000 );
}
#endif
You could use cv::waitKey(ms) but is there a reason you don't want to use the normal c++ functions?
Keep in mind that waitKey(ms) will ONLY work if there is a window opened. If not, it will compile just fine but never perform the wait. Better use the native c++ commands.
@StevenPuttemans maybe irrelevant or maybe it is. An important aspect of programming is using the right terminology, to me it is a indicator of one's understanding of the problem or knowledge of programming. There is also a parallel with programming because it is a very strict skill, one single wrong character could give completely different result of your program - we've all experienced this ;). So read this and then this.
Lol you are going to give me a lesson in syntax versus statement considering is have a master of science in IT? Again, what brings your remark as an extra to the topic starters question? Except from he using a wrong concept word, and you pointing him on that, i do lot see the benefit of such remark without further explanation...
