JPEG image in OpenCV format in memory

Question

Is it possible to save the image in a line instead of a file with OpenCV?

I found exactly this function in the docs:

int cvSaveImage(const char* filename, const CvArr* image)

And it can only be saved in files.

Answer 1

How do you want to encode an image in a string?
You could just save the red, green, blue values ​​as comma-separated strings, but encoding a binary image as something like base64 would be more compact.

Edit: if you mean the jpeq format in memory, see - OpenCV for use in memory buffers or file pointers

Answer 2

, char * IplImage? , , imageData, imageDataOrigin ..
