It should be understood that the method may be adapted to other exemplary implementation environments and be specifically executed by devices in other implementation environments, and the implementation environments to which the method is adapted are not limited by the present embodiment.
Referring to fig. 2, fig. 2 is a flowchart of an exemplary transformation method of the present application, where the transformation method at least includes steps S201 to S205, including:
s201, detecting a touch event of a user on a touch screen;
s202, detecting the state of an element displayed on a touch screen after the touch event is detected, and acquiring a first state and a second state of the element;

Therefore, the reusability of the object can be improved, memory Churn generated when new graphic objects are repeatedly created is reduced, the performance loss of the vehicle machine is reduced, the stability and the expression effect of element transformation are improved, a better visual effect is provided for a user, and zooming is smooth and fluent.
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, in which an Android system is operated, and a target element, such as a picture, is displayed on a display screen of the vehicle-mounted computer, and the picture may be scaled or/and translated by the method shown in fig. 2 to transform the picture into a state desired by a user.
A picture is essentially a collection of points that form a matrix, and therefore the transformation of a picture is essentially a transformation of a matrix. In the Android system, the method comprises the following steps:
an external matrix change monitor (Listener) changes the external matrix, the total matrix also changes, and the display position of the picture changes as the external matrix changes.
An object Pool (Objects Pool) in which several Objects are pre-stored, which Objects can be understood as a total matrix.
Matrix Pool and rectangular Pool (Matrix & rectangular Pool) are specific implementations of object Pool, controlling the number of Matrix objects generated during actual operation.
Scaled image computation tools (Math Utilities) provide the various computations required in the graphics scaling process, such as common computations for intermediate points, scaling, matrix dot inversion, etc.
Scaling an image view, intercepting a touch event, judging a gesture of the touch event, and issuing the touch event to finish view (picture) scaling or/and translation. In the Android system, a plurality of gestures are defined, and the transformation of pictures can be completed through the gestures. The plurality of gestures may include, for example, the following:
action_up, action_cancel-due to the lifting or canceling of the finger, stopping the image change operation that may exist before, and restoring the default no-touch state;
action_pointer_up-lifting of one or more fingers generated during gesture operation, at this time, the zoom control point needs to be judged again to keep the smoothness of the zoom operation;
the action_down-state of finger press, normally scroll translation, if there is a previous zoom change, the current scroll translation operation is not allowed;
action_pointer_down-in the zooming process, a touch point is added, and at the moment, the current zooming operation is needed to be carried out by forcedly switching to zooming;
active _ MOVE-there are two possibilities, panning or zooming at this time, and a determination of whether the maximum ratio is exceeded needs to be added at this stage to reduce the likelihood of display anomalies in extreme cases.
A Gesture Detector (gestme Detector) assists the zoom image view to determine the Gesture of the touch event. The following gestures are also defined on the basis of zooming the image view in a custom manner: such as jerk (flick), long press (long click), double click (double tap), etc.
The following describes the detailed steps of the transformation method for transforming pictures according to the present invention by means of 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 can enable a user to operate the electronic terminal by lightly touching icons or characters on the display screen with a finger, a touch pen or the like, 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 the single-point touch event generated by a single finger or the multi-point touch event generated by more than two fingers through the number of touch points. When the number of the touch points is detected to be one, judging that the touch event is a single-point touch event; when more than one touch point is detected, the touch event is determined to be 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 that may include different directions, such as up-slide translation, down-slide translation, left-slide translation, right-slide translation, and the like; when the touch event is a multi-touch event, the operation on the touch screen is a zoom operation.
It should be noted that the position of the touch point may be identified by a coordinate value in a touch coordinate system of the touch screen.
In an exemplary embodiment of the present application, in step S202, after the touch event is detected, the state of the picture displayed on the touch screen is detected, and the first state and the 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 the picture processing the first state, and B represents the picture processing the second state. The first state includes the position and size of the picture at the beginning (without change), and the second state includes the size and position of the picture after the change.
In an exemplary embodiment of the present application, in step S203, at least one object generated in the process of transforming the picture from the first state to the second state is acquired.
In this embodiment, the external matrix change monitor monitors the change of the external matrix, and when the external matrix (the matrix composed of mscal and MSKEW in fig. 3) changes, the total matrix (the matrix shown in fig. 3) also changes, and the transformation of the picture can be obtained by calculating the total matrix parameters, so as to realize the transformation of the picture. Wherein the transformation parameters include at least one of: translational displacement, scaling; the transformation of the picture includes at least one of: and (5) translating and zooming.
In the process of transforming the picture from the first state to the second state, the external matrix is transformed multiple times, i.e. a plurality of new external matrices are generated. In this embodiment, the external matrix is defined as objects, i.e. a plurality of objects are generated during the transition of the picture from the first state to the second state. If the first state is transformed into the second state, which is defined to include a plurality of sub-states, each sub-state corresponds to an object, and the sub-state is transformed based on the previous sub-state. The calculation of the middle point, the scaling ratio, the matrix point inversion and the like of the picture scaling is realized through 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 the object pool, and an associated object of the pre-stored object that is 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 an association matrix. Multiple external matrices are generated in the process of transforming the picture from the first state to the second state, and then multiple total matrices are obtained through multiple computations, so that the time for transforming the picture state is increased due to multiple computations in the process of transforming the picture. For one picture translation, the whole process may generate hundreds of external matrixes, so that calculation is performed hundreds of times, and picture display is performed hundreds of times, so that a clamping 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 association object with association relation with the pre-stored object exists in the object pool, the subsequent calculation is needed by utilizing the association object, and the association object is not needed to be calculated based on the generated object, namely the total matrix is obtained through the external matrix calculation, so that the middle calculation process is omitted, and the time for picture transformation is saved. The association relation refers to that the association object is obtained after the pre-stored object is transformed. Taking one calculation as an example, if the total matrix may take 100ms by external matrix calculation, and the correlation matrix is obtained by matching, the required time is generally less than 50ms, which can save one time.
In an exemplary embodiment of the present application, referring to fig. 4, fig. 4 is a flowchart of obtaining transformation parameters, including steps S401 to S403:
step S401, according to the touch event, the number of touch points is obtained;
step S402, when the number of the touch points is one, taking the displacement of the touch point movement as the translation displacement;
step S403, when the number of the touch points is more than one, acquiring a center point of each touch point; and determining the scaling according to the distance between each touch point and the center 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, after the step of matching the at least one object with the pre-stored object in the object pool, the method further includes: establishing an associated object of an object which is not matched with the pre-stored object; and transforming the element by using the newly-built association object.
Specifically, referring to fig. 5, fig. 5 is a flowchart of establishing an association object. In fig. 5, the establishing the association object of the object not matching the pre-stored object includes steps S501 to S502:
s501, obtaining a conversion parameter for converting a former sub-state into a latter sub-state;
s502, according to the transformation parameters, transforming the object corresponding to the previous state to obtain a transformed transformation object, wherein the transformed transformation object is used as a newly-built association object.
Many methods are provided in Android for picture processing modes, while Matrix (Matrix) is a component closer to the bottom layer and is more flexible to operate than other tools (e.g., canvas). In Android, the matrix is a 3x3 matrix, and different from the matrix in mathematics, the content represented by each bit has a special meaning, and the expression is as follows:
specifically, referring to fig. 3, the proportional rotation part includes two sets of parameters, namely MSCALE and MSKEW. The MSCALE group parameters control the scaling in the X, Y direction, while the MSKEW group parameters control the miscut in the X, Y direction. The translation part alone has a set of parameters, MTRANS, controlling the translation in the X, Y direction. While the lowest one uses less, usually the MPERSP 2 is assigned for distinguishing between vectors and points.
Specifically, assume that the scaling in the x-axis is k 1 The y-axis scale is k 2 The original image has width and height of x respectively 0 、y 0 Then the post-scaling formula is calculated at this time:
x＝k 1 ×x 0
y＝k 2 ×y 0
at this time, the expression is expressed by matrix calculation, and then the following is obtained:
from the above equation, for a scaling process, the parameter to be recorded is k 1 、k 2 、x 0 、y 0 . Similarly, in the translation process, if the translation variables are Δx and Δy respectively, the translation formula and the formula after being converted into the matrix are:
x＝x 0 +Δx
y＝y 0 +Δy
and transmitting the parameters into the part matrix according to the correct sequence, so that a changed total matrix, namely the associated object, can be correctly obtained.
In an exemplary embodiment of the present application, after establishing 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 no corresponding associated object exists in the object pool, a new associated object is built and stored in the object pool, so that the associated object is called in the conversion process of the subsequent picture, the multiplexing rate of the associated object is improved, and the picture conversion time is saved.
In an exemplary embodiment of the present application, in the process of transforming the element with the association object, the method further includes: acquiring a first transformation parameter of the element transformed from the first state to the second state; comparing the first transformation parameter with a transformation parameter threshold; and stopping the transformation of the element when the first transformation parameter is equal to the transformation parameter threshold. Wherein the transformation parameter threshold comprises a translational displacement threshold or/and a scaling threshold.
When the first conversion parameter is equal to the conversion parameter threshold, it is described that the picture is converted to the maximum position at this time, and thus the conversion operation for the picture is stopped. In the embodiment, the maximum magnification is scaled by constraint, the maximum magnification is set as a boundary value, and when the boundary value is triggered, the operation of continuing scaling or the translation operation is canceled, so that the constraint on the extreme condition is realized.
Fig. 6 is a block diagram of a conversion device shown in an exemplary embodiment of the present application. The device can be applied to the implementation environment shown in fig. 1 and is particularly configured in an intelligent terminal. The apparatus may also be adapted to other exemplary implementation environments and may be specifically configured in other devices, and the present embodiment is not limited to the implementation environments to which the apparatus is adapted.
