Detailed Description

template<class Type>
class vpImageQueue< Type >

Create a queue containing images and optional additional strings that could be useful to save additional information like the timestamp.

This call is to use with vpImageStorageWorker.

vpImageQueue< Type >::vpImageQueue	(	const std::string &	seqname,
		int	record_mode
	)

inline

Queue (FIFO) constructor. By default the max queue size is set to 1024*8.

Parameters

[in]	seqname	: Generic sequence name like `"folder/I%04d.png"`. If this name contains a parent folder, it will be created.
[in]	record_mode	: 0 to record a sequence of images, 1 to record single images.
