The second coordinate data answered determines relative level distance and phase between second coordinate data and first coordinate data
To vertical distance.
As the preparation before the step, it is necessary first to which load needs the multimedia file that positions, and by multimedia
Progress after file load is as starting progress；Meanwhile an adjustment region is created for user, the default tune of adjustment region is set
Whole precision, precision adjustment ratio and default progress adjustment amount.
It should be noted that also corresponding most ditty further can be arranged for adjustment region other than the above attribute
Whole precision and maximum Adjustment precision, adjust ratio as precision, can determine in the following manner:
(1) ratio of the difference between Adjustment precision and minimum Adjustment precision and adjustment region vertical direction peak will be defaulted
It is worth absolute value as precision and adjusts ratio；
(2) absolute difference between Adjustment precision and the maximum Adjustment precision will be defaulted and the adjustment region is vertical
The ratio absolute value of direction minimum adjusts ratio as precision；
Both the above precision adjustment ratio-dependent mode is directed to respectively adjusts upward and adjusts downwards two kinds of situations, but nothing
By being to take any mode, need vertical height value corresponding with the default Adjustment precision in adjustment region being set as zero,
Relative zero is determined with this.
For how to obtain the relative distance between the first coordinate and the second coordinate, can directly with the data in coordinate into
Row calculates, or calculates the linear distance between the two coordinate, then according between the straight line and trunnion axis of two coordinates of connection
Angle, be calculated using trigonometric function, specific calculation can by those skilled in the art's flexible choice, these all this

Wherein Tmax is maximum Adjustment precision, and Tmin is minimum Adjustment precision, and To is the Adjustment precision of slider bar default.
Soc is the distance of point C to point O, is the angle of lines OC and slider bar.Dup is that slider bar can extremely drag range areas most upper limb
Distance, Ddown is that slider bar can extremely drag the distance of range areas most lower edge.
If calculated Fc has exceeded the range of file, corresponding rearmost position or starting position are taken.
The progress distance of horizontal direction dragging progress distance and vertical direction is mapped as to the source location of load document
Or object content position.
The progress distance of horizontal direction dragging progress distance and vertical direction is mapped as the target position of load document by S204
It sets a little or object content position.
S205 feeds back and shows positioning result.
In the dragging process to load document, by pinpoint source location or object content position with visual
The mode for changing prompt feeds back to user, and user is allowed to perceive current accurate positioning progress and Adjustment precision to load document
(for example, the slider bar of visual document can prompt user current in dragging process by spatial variations shared by frame thumbnail
Progress adjustment corresponding variation has occurred；The slider bar of text file can be by shared by page thumbnails in dragging support city
Corresponding variation etc. has occurred come the progress adjustment for prompting user current in spatial variations).
