§ read_image_to_memory()

virtual bool base_camera_server::read_image_to_memory	(	unsigned	minX = `255`,
		unsigned	maxX = `0`,
		unsigned	minY = `255`,
		unsigned	maxY = `0`,
		double	exposure_time = `250.0`
	)

pure virtual

Read an image to a memory buffer.

Max < min means "whole range". Setting binning > 1 packs more camera pixels into each image pixel, so the maximum number of pixels has to be divided by the binning constant (the effective number of pixels is lower and pixel coordinates are set in this reduced-count pixel space). This routine returns false if a new image could not be read (for example, because of a timeout on the reading because we're at the end of a video stream).
