You work with new as an originally declared iplimage.
Copy cv mat to iplimage.
All the other ways are too complicated and this is the best one.
Cv mat is the new type introduce in opencv2 x while the iplimage is the legacy image structure.
It also implements reference counting.
Taking a look at core src matrix cpp it seems that indeed the constructor cv mat iplimage has disappeared.
Cv mat a b.
Default additional arguments.
Do remember that you need to allocate the iplimage structure which is lack.
You have cv mat old iplimage copy old.
You will need to extract the image header information manually.
A will point to b s data and the reference count for it will be incremented.
So when you do a regular copy such as.
It passes the number of dimensions 1 to the mat constructor but the created array will be 2 dimensional with the number of columns set to 1.
Cv mat is a header that points to a data pointer which holds the actual image data.
Iplimage ipl.
Iplimage new image copy.
But i found this alternative.
Use a copy constructor or assignment operator where there can be an array or expression on the right side see below.
It holds the number of cv mat headers currently pointing to that data pointer.
Cv mat m cv cvarrtomat ipl.

It is more efficient than manually converting the pixels to the qimage but you have to keep the original cv mat image in memory.
Thanks for this article.
I would be able to run the iplimage to mat conversion but i am getting problem with mat to iplimage program i am running the following code in vs 2008 using opencv 2 4 6.
To convert from cv mat to qimage you could try to use the qimage uchar data int width int height format format constructor as follows mat is a cv mat.
