First, it should be noted that, in an exemplary embodiment of the present application, the transformation method shown in fig. 2 may be applied to a vehicle-mounted computer, where an Android system runs in the vehicle-mounted computer, and a target element, such as a picture, is displayed in a display screen of the vehicle-mounted computer, and the picture may be zoomed or/and panned by the method shown in fig. 2 to transform the picture to a state desired by a user.
A picture is essentially a collection of points that form a matrix, and thus, the transformation of a picture is essentially a transformation of a matrix. In the Android system, the method comprises the following steps:
when the external matrix changes, the total matrix also changes, and the display position of the picture and the like still change as the external matrix changes.
An object Pool (Objects Pool) in which several Objects are pre-stored, which can be understood as an overall matrix.

In the Android system, several gestures are defined by which the transformation of the picture can be done. The plurality of gestures may include, for example:
ACTION _ UP, ACTION _ CANCEL — stopping a possible previous image change operation due to the lifting or cancellation of the finger, and returning to a default non-touched state;
ACTION _ POINTER _ UP-lifting of a certain finger or certain fingers generated in the gesture operation process, wherein the zoom control point needs to be judged again at this time so as to keep the fluency of the zoom operation;
ACTION _ DOWN-state of finger press, normal case is scroll translation, if there is zoom change before, then not allow the current scroll translation operation;
ACTION _ POINTER _ DOWN-touch points are added in the zooming process, and at the moment, the zooming needs to be forcibly switched to perform the current zooming operation;
ACTION MOVE-there are two possibilities at this time, panning or zooming, and then a decision whether to exceed the maximum ratio needs to be added at this stage to reduce the possibility of display anomalies in extreme cases.
And a Gesture Detector (Gesture Detector) for assisting the zoomed image view to judge the Gesture of the touch event. The following gestures are also defined on the basis of zooming the image view in a self-defining way: such as jerk, long press, double click, etc.
The following describes the detailed steps of the transformation method for transforming a picture according to the present invention with specific embodiments.
In an exemplary embodiment of the present application, in step S201, a touch event of a user on a touch screen is detected.
As described above, the touch screen enables a user to operate the electronic terminal by lightly touching the icons or characters on the display screen with a finger or a stylus, so that human-computer interaction is more direct. The touch event is generated when a user touches the touch screen with a finger. The touch event is divided into a single-point touch event and a multi-point touch event, and the touch event can be judged to be a single-point touch event generated by a single finger or a multi-point touch event generated by more than two fingers according to the number of touch points. When the number of the detected touch points is one, judging that the touch event is a single-point touch event; and when more than one touch point is detected, determining that the touch event is a multi-point touch event. If the touch event is a single-point touch event, the operation on the touch screen is a translation operation, and the translation operation includes translation operations in different directions, such as up-sliding translation, down-sliding translation, left-sliding translation, right-sliding translation, and the like; when the touch event is a multi-point touch event, the operation on the touch screen is a zoom operation.
It should be noted that the position of the touched point can be identified by the coordinate value in the touch coordinate system of the touch screen.
In an exemplary embodiment of the present application, in step S202, after the touch event is detected, a state of a picture displayed on the touch screen is detected, and a first state and a second state of the picture are obtained.
After the touch event is detected, the picture can be considered to be changed, so that the state of the picture can be detected; the state of the picture comprises the size and the position of the picture, wherein A represents processing the picture in the first state, and B represents processing the picture in the second state. The first state comprises the initial (unchanged) position and size of the picture, and the second state comprises the transformed size and position of the picture.
In an exemplary embodiment of the present application, in step S203, at least one object generated during the process of transforming the picture from the first state to the second state is obtained.
In this embodiment, the change of the external matrix is monitored by the external matrix change monitor, and when the external matrix (a matrix formed by the MSCALE and the MSKEW in fig. 3) changes, the total matrix (the matrix shown in fig. 3) also changes, and the picture transformation can be obtained by calculating the parameters of the total matrix, so as to implement the picture transformation. Wherein the transformation parameters include at least one of: translation displacement and scaling; the transforming of the picture comprises at least one of: and (5) translating and zooming.
During the process of changing the picture from the first state to the second state, the external matrix of the picture is changed for a plurality of times, namely, a plurality of new external matrices are generated. In this embodiment, the external matrix is defined as an object, that is, a plurality of objects are generated during the process of converting the picture from the first state to the second state. If the first state is transformed to the second state and is defined to include a plurality of sub-states, each sub-state corresponds to an object, and the latter sub-state is transformed based on the former sub-state. The calculation of the middle point, the scaling ratio, the matrix point inversion and the like of the picture scaling is realized by a scaled image calculation tool (Math Utilities).
In an exemplary embodiment of the present application, in step S204, the at least one object is matched with a pre-stored object in an object pool, and an associated object of the pre-stored object successfully matched with the at least one object is obtained.
During the transformation of the picture, the external matrix changes, which results in a change of the total matrix. In the present embodiment, the total matrix is defined as the correlation matrix. When a plurality of external matrices are generated during the process of converting a picture from a first state to a second state, a plurality of total matrices are obtained through a plurality of computations, so that the time for converting the picture state is increased due to the plurality of computations during the process of converting the picture. In the case of one picture shift, hundreds of external matrices may be generated in the whole process, and thus hundreds of calculations are performed, and then hundreds of picture displays are performed, and a pause occurs in the picture conversion process.
In the application, the generated object is matched with the pre-stored object in the object pool, and if the matching is successful, the generated object exists in the pre-stored object. Because the associated object having the association relation with the pre-stored object exists in the object pool, the associated object is used for subsequent calculation, the associated object does not need to be calculated based on the generated object, namely, the total matrix is obtained through external matrix calculation, so that the intermediate calculation process is omitted, and the time for picture transformation is saved. Wherein, the association relation refers to that the pre-stored object is transformed to obtain the associated object. Taking a calculation as an example, if the total matrix obtained by the external matrix calculation may take 100ms, and the correlation matrix obtained by matching, the time required is generally less than 50ms, so that one time can be saved.
In an exemplary embodiment of the present application, please refer to fig. 4, where fig. 4 is a flowchart for obtaining transformation parameters, which includes steps S401 to S403:
step S401, acquiring the number of touch points according to the touch event;
step S402, when the number of the touch points is one, taking the displacement of the touch points as the translational displacement;
step S403, when the number of the touch points is more than one, acquiring the central point of each touch point; and determining the scaling according to the distance between each touch point and the central point.
In an exemplary embodiment of the present application, if there is an object that does not match the pre-stored object in the at least one object, the step of matching the at least one object with the pre-stored object in the object pool further includes: establishing an associated object of the object which is not matched with the pre-stored object; and transforming the element by using the newly-established associated object.
Specifically, referring to fig. 5, fig. 5 is a flowchart of establishing an association object. In fig. 5, the establishing of the associated object of the object not matching with the pre-stored object includes steps S501 to S502:
s501, acquiring a conversion parameter for converting a previous substate into a next substate;
s502, according to the transformation parameters, transforming the object corresponding to the previous state to obtain a transformed object, wherein the transformed object is used as a newly-established associated object.
Many methods are provided in Android for processing pictures, and the Matrix (Matrix) as a component closer to the bottom layer is more flexible to operate than other tools (such as canvas). In Android, the matrix is a 3x3 matrix, and unlike the matrix in mathematics, the content represented by each bit has a special meaning, and the expression is as follows:
specifically, please refer to fig. 3, wherein the proportional rotation part comprises two sets of parameters, MSCALE and MSKEW, respectively. The MSCALE group parameters control the X, Y direction scaling, while the MSKEW group parameters control the X, Y direction miscut. The translation component alone has a set of parameters, MTRANS, that control X, Y the direction of translation. While the lowest isometric transformation is used less often MPERSP _2 is assigned a value to distinguish between vectors and points.
In particular, assume a scaling of k in the x-axis 1 Y-axis scaling of k 2 The width and height of the original image are x 0 、y 0 Then there is now a calculated scaled formula:
x＝k 1 ×x 0
y＝k 2 ×y 0
at this time, the expression is expressed by matrix calculation, and then:
as can be seen from the above equation, for a scaling process, the parameter to be recorded is k 1 、k 2 、x 0 、y 0 . Similarly, during the translation, if the translation variables are Δ x and Δ y, respectively, then it is determined thatThe translation formula and the formula after conversion into a matrix are:
x＝x 0 +Δx
y＝y 0 +Δy
the parameters are transmitted into the partial matrix according to the correct sequence, so that the changed total matrix, namely the associated object, can be correctly obtained.
In an exemplary embodiment of the present application, after the creating of the associated object of the object that does not match the pre-stored object, the method further includes: and storing the newly-built associated object into the object pool. It should be noted that, after there is no corresponding associated object in the object pool, a new associated object is established and stored in the object pool, so that the associated object is called in the subsequent picture conversion process, thereby improving the multiplexing rate of the associated object and saving the picture conversion time.
In an exemplary embodiment of the present application, in transforming the element with the associated object, the method further includes: acquiring a first transformation parameter for transforming the element from the first state to the second state; comparing the first transformation parameter to a transformation parameter threshold; stopping the transformation of the element when the first transformation parameter equals the transformation parameter threshold. Wherein the transformation parameter threshold comprises a translational displacement threshold or/and a scaling threshold.
It should be noted that, when the first transformation parameter is equal to the transformation parameter threshold, it is stated that at this time, the picture is transformed to the maximum position, and thus the transformation operation on the picture is stopped. In the embodiment, the maximum magnification of zooming is restricted, the maximum magnification is set as a boundary value, and when the boundary value is triggered, the operation of continuing zooming or the translation operation is cancelled, so that the restriction on extreme conditions is realized.

The device can be applied to the implementation environment shown in fig. 1 and is specifically configured in an intelligent terminal. The apparatus may also be applied to other exemplary implementation environments, and is specifically configured in other devices, and the embodiment does not limit the implementation environment to which the apparatus is applied.
