Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below It will the technical scheme of the embodiment of the invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist Every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
Referring to FIG. 1, it is a kind of the first implementation of the method for head portrait adjustment provided in the specific embodiment of the invention The method flow diagram of example.As shown, this method, comprising:
Step S101: the position of the beginning and end of slide is obtained.
Slide is carried out on mobile terminal screen, obtains the position of the beginning and end of slide, it is specific sliding The realization of dynamic operation has realization in the prior art, is not described further herein.
Step S102: offset of the terminal relative to starting point is calculated.
In the treatment process of slide, beginning and end is described by coordinate, can be counted according to corresponding coordinate value Calculate offset of the terminal relative to starting point.Specific offset is divided into horizontal and vertical (coordinate system relative to system default) two A direction, such as the offset of horizontal direction is dx, the offset of vertical direction is dy.
Step S103: according to the position of element to be adjusted in the mobile head portrait of the offset.
Element to be adjusted such as eyeball, nose, mouth in head portrait etc. it is arranged an anchor point, is positioned with the position of anchor point The position of element to be adjusted treats and adjusts the adjustment of element namely to the adjustment of anchor point, such as the position of anchor point is p (x, y), Position after being so adjusted according to offset above-mentioned is p (x+dx, y+dy).
In conclusion passing through the position for the beginning and end for obtaining slide;The terminal is calculated relative to starting point Offset;According to the position of element to be adjusted in the mobile head portrait of the offset;The manipulation precision during head portrait adjustment is improved, Reduce workload when image design.
Referring to FIG. 2, it is a kind of the second implementation of the method for head portrait adjustment provided in the specific embodiment of the invention The method flow diagram of example.As shown, this method, comprising:
Step S201: the head portrait and element to be adjusted are initialized.
Please refer to Fig. 3, Fig. 4 and Fig. 5, be respectively the schematic diagram of head portrait, the schematic diagram of element to be adjusted and head portrait and to The schematic diagram for adjusting element initialization needs to initialize head portrait and element to be adjusted, in the present embodiment before generating final image In, the element to be adjusted of initialization is eyeball, and the head portrait of initialization is the image that head goes out except eyeball.In first display, eye Pearl is arbitrarily set to the position of eye socket, and the subsequent specific location further to eyeball in eye socket is adjusted.
Step S202: the position of the beginning and end of slide is obtained.
During specific adjustment, is operated since any position of operation interface, be not necessarily intended to fall in starting point Eyeball position, the track of slide is only projected to element to be adjusted by last adjustment, such as the eye in the present embodiment Pearl.
Step S203: offset of the terminal relative to starting point is calculated.
Assuming that the position of the starting point obtained is p1 (x1, y1), the position of terminal is p2 (x2, y2), then corresponding offset Horizontal offset is w=x2-x1;Offset of vertical amount is h=y2-y1.
Step S204: confirm the offset without departing from default mobile threshold value.
For between element to be adjusted and head portrait, there is relatively stringent relative position, element to be adjusted can only be set to head Within a certain approximate region of picture.So needing to judge whether offset exceeds default mobile threshold value, that is, need to judge water As soon as whether flat offset and offset of vertical amount have and have exceeded corresponding threshold value, if having one beyond illustrating that adjustment can not be real It is existing.
Step S205: according to the offset it is scaled or amplification obtain amount of movement.
It, can be by way of zooming in or out in order to obtain accurate or quick adjustment during specific adjustment Obtain amount of movement, such as slide 1cm, the mobile 0.5cm of element to be adjusted or slide 0.5cm, element movement 1cm to be adjusted.
Step S206: by the position of element to be adjusted in the mobile head portrait of the moving direction and moving distance of the amount of movement.
In the specific implementation process, a slide can be considered as the combination of multiple tiny slides, adjust treating When element is adjusted, element to be adjusted can move in real time with terminal, and the effect of adjustment is more intuitive.
Step S207: when the offset reaches preset range, the head portrait be switched to the preset range it is corresponding to Determine head portrait.
For it is different wait adjust element for, different modes of emplacement can generate different expression effects, can adjust at this time Whole head portrait and current location matches obtain new image design effect.Such as eyeball often indicates sadness in eye socket lower part Expression, the corners of the mouth is downward at this time;If eyeball moved up, the expression that do not consider worth doing is often indicated, the corners of the mouth is tilted to side at this time. In two different eyeball positions, corresponding two different head portraits, being adjusted combination can be obtained design effect abundant.
In conclusion passing through the position for the beginning and end for obtaining slide;The terminal is calculated relative to starting point Offset;According to the position of element to be adjusted in the mobile head portrait of the offset;The manipulation precision during head portrait adjustment is improved, Reduce workload when image design.Meanwhile the processing mode zoomed in or out allows and just does the more arbitrarily variation of head portrait Design effect more abundant can be generated.
The following are a kind of embodiment of the device of head portrait adjustment of this programme, the embodiment of the device of head portrait adjustment is based on head portrait The embodiment of the method for adjustment realizes that the not most description in the embodiment of system please refers to the embodiment of method.
