Picture sliding display method, terminal and computer storage medium

Technical Field

The invention relates to the technical field of internet, in particular to a picture sliding display method, a terminal and a computer storage medium.

Background

In various terminal applications or web pages, an operation mode of sliding display and a corresponding function are generally provided, a user can trigger sliding display of a plurality of pictures through the sliding operation, and the operation mode is described as a specific application in order to facilitate visual perception: fig. 1 shows a schematic view of pages of a slide finding similar book provided in a reading application. In fig. 1, the upper half displays the pictures of the covers of books collected in the bookshelf, and can be switched by sliding left and right, and the lower page part lists and displays the similar recommended books of the books in the upper half, which are slid to the middle position. And, in the upper half, there is a zooming effect of the book cover picture sliding, i.e., the book cover picture appears to be gradually larger and then gradually smaller as it moves in a certain direction, and the size is the largest when the book cover picture is in the middle position.

In the prior art, the moving and zooming of the book cover pictures are realized by using an interface method provided by a system, in the realization process, the setting of the relative position of the book cover pictures is fixed, for example, the distance between the central points of two adjacent book cover pictures is always 1 unit length.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Fig. 2 shows a flowchart of a picture sliding display method according to an embodiment of the present invention. The method is used for keeping the distance between two adjacent pictures unchanged in the process of zooming and moving the pictures, and can be executed by any terminal with data processing capability, including but not limited to mobile phones, computers, tablets and electronic readers. As shown in fig. 1, the method comprises the steps of:

step S210: monitoring a sliding operation event in a target window; a plurality of placeholder pictures are set in the target window.

The target window refers to a window capable of displaying a picture in a sliding and zooming manner, for example, the window with the dark color in the upper half part in fig. 1.

The target window is internally provided with a plurality of placeholder pictures, the number of the placeholder pictures is the same as the number of pictures to be displayed which can be displayed in the target window at the same time, and preferably, the number of the placeholder pictures is an odd number so as to highlight the pictures at the middle position; the occupied size of each position of the occupied picture in the sliding process is symmetrical, the occupied size is usually the largest in the middle position, and the occupied size is gradually reduced towards the two sides. And the placeholder picture is used for limiting the display size and position of the picture to be displayed. Still taking fig. 1 as an example, the number of placeholders is 5, and when 5 placeholders are displayed statically (not responding to a sliding operation event), the placeholders of the remaining placeholders are smaller than and the same size as the placeholder at the center position, except that the placeholder at the center position is the largest.

Specifically, when the sliding operation event is monitored, it may be determined that the scaling movement of the placeholder picture in the target window is triggered, and at this time, the following steps S220 to S240 are performed to keep the distance between two adjacent placeholder pictures unchanged, that is, the distance between adjacent edges of two adjacent placeholder pictures is unchanged.

Step S220: in the process of responding to the sliding operation event, the distance between each placeholder picture and the center of the target window is obtained in real time; at least two placeholder pictures to be adjusted are selected from the plurality of placeholder pictures according to the space size.

Specifically, in the process of moving the placeholder pictures, the distance between each placeholder picture and the center of the target window is obtained in real time, wherein the center of the target window can be a central point or a central line; the spacing size may reflect movement of the placeholder picture to an off-center position; and the placeholder pictures at each position should have corresponding placeholder sizes, and then whether the placeholder pictures can change in size in the process of continuously moving can be determined according to the size of the space, and meanwhile, the change in size can cause the change in distance between the placeholder pictures and the adjacent placeholder pictures. Due to the symmetry of the occupied sizes, the sizes of at least two occupied pictures can be changed in the sliding process, and the number of the occupied pictures to be adjusted is at least two.

Fig. 3 is a diagram illustrating a target window in a specific example. In fig. 3, the number of the placeholders is 5, the dotted line in the figure is the vertical center of the target window, the sliding direction is leftward, it can be determined according to the distance that the sizes of the

placeholders

2,3,4, and 5 change in the subsequent moving process, and then the

placeholders

2,3,4, and 5 can be determined as placeholders to be adjusted.

It should be noted that, as the movement continues, the determined placeholder pictures to be adjusted change, and therefore new placeholder pictures to be adjusted need to be determined continuously according to the distance obtained in real time.

Step S230: acquiring the placeholders of the at least two placeholder pictures to be adjusted in real time, performing cooperative adjustment processing on the placeholders of the at least two placeholder pictures to be adjusted, and keeping the placeholders of other placeholder pictures except the placeholder pictures to be adjusted unchanged.

In the embodiment of the invention, the coordinated adjustment processing is only carried out on the placeholder pictures to be adjusted, and other placeholder pictures are not interfered, so that the calculated amount can be reduced, the display fluency can be improved, and the distance between other placeholder pictures can be ensured not to be changed.

Specifically, the processing of the coordinated adjustment is performed on the placeholder pictures to be adjusted, wherein the processing of the coordinated adjustment includes a scaling adjustment processing of eliminating the size of the placeholder pictures to be adjusted, that is, the placeholder size of at least one or more placeholder pictures is increased, and the placeholder sizes of the remaining placeholder pictures are decreased by the same amplitude, and a translation adjustment processing of keeping the distance between the adjacent placeholder pictures to be adjusted unchanged. Meanwhile, the occupied sizes of other occupied pictures are kept unchanged, and the occupied sizes among other occupied pictures can be kept unchanged.

Step S240: and covering and displaying the pictures to be displayed with corresponding sizes on the placeholder pictures according to the placeholder sizes of the placeholder pictures.

Specifically, the to-be-displayed pictures are covered on the placeholder pictures and are moved and zoomed for display along with the movement and the zooming of the placeholder pictures, wherein in the process that a certain placeholder picture is moved out from one side of the target window and moved in from the other side, the system replaces the to-be-displayed pictures according to the sequence of the to-be-displayed pictures to be covered on the placeholder pictures and then enters the target window.

The picture sliding display method provided by the embodiment of the invention can be widely applied to any target window supporting picture moving, zooming and displaying through sliding operation, wherein a typical application is as shown in fig. 1 and applied to pages recommended by similar books, in the application, the pictures to be displayed are book cover pictures, and the book cover pictures displayed on a plurality of placeholder pictures in a covering mode are different.

According to the picture sliding display method provided by the embodiment, in the process of monitoring the sliding operation event and responding to the sliding operation event, the distance between each placeholder picture and the center of the target window is obtained in real time, the size of the distance can reflect whether the placeholder picture is subjected to size change in the process of continuously moving, and on the basis, the placeholder picture to be adjusted is selected according to the size of the distance; and then, carrying out cooperative adjustment processing on the placeholder pictures to be adjusted, and keeping the placeholders of other placeholder pictures unchanged, so that the distance between every two adjacent placeholder pictures can be kept unchanged. Therefore, according to the scheme of the embodiment, the placeholder pictures to be adjusted are selected according to the space size, the placeholder pictures with changeable placeholders can be accurately determined, then the coordinated adjustment processing is carried out on the placeholder pictures to be adjusted, the influence on the distance between the adjacent placeholder pictures due to the size change of the placeholder pictures to be adjusted can be avoided, the distance between the adjacent placeholder pictures is always kept unchanged, the orderliness in the sliding zooming display process is improved, the coordinated adjustment processing is only carried out on the placeholder pictures to be adjusted, the calculation amount can be reduced, and the page display fluency is improved.

Fig. 4 is a flowchart illustrating a picture sliding display method according to another embodiment of the present invention. As shown in fig. 4, the method comprises the steps of:

step S410: monitoring a sliding operation event in a target window; a plurality of placeholder pictures are set in the target window.

And if the placeholder picture is a transparent and invisible view, the placeholder picture is in an invisible state for the user in the adjusting process.

Specifically, after the sliding operation event is monitored, the plurality of placeholder pictures are moved according to the sliding direction of the sliding operation event, wherein the following method can be invoked to implement the movement: the screen ViewDidScall (UIScrollView) enables the picture to be displayed, which is overlaid on the placeholder picture, to move along with the movement of the placeholder picture. Taking the placeholder picture 3 in fig. 3 as an example, if the sliding direction is from right to left, the placeholder picture 3 moves from right to left, and when the placeholder picture moves to the leftmost side, the placeholder picture moves out of the target window, and then enters from the right side of the target window.

Step S420: in the process of responding to the sliding operation event, the distance between each placeholder picture and the center of the target window is obtained in real time; at least two placeholder pictures to be adjusted are selected from the plurality of placeholder pictures according to the space size.

In the target window, when the distance between the placeholder picture and the center is displayed to be far away from the center, the placeholder size becomes smaller, otherwise, when the placeholder picture is displayed to be close to the center, the placeholder size becomes larger, in some optional embodiments, the minimum size of the bottom protection can be set to avoid the situation that the size of the placeholder picture at the edge of the window is too small, and when the minimum size is reached, the placeholder picture is further moved to two sides and is not reduced any more. The gradual effect of the zooming display can be realized by calling the following method: layout SubView (_ view: ZYScaleBaseShell, viewAt index: NSInteger).

Specifically, the sliding modes supported by the target window are different, and the obtained distance reference is also different, wherein if the sliding direction of the sliding operation event is a horizontal direction from left to right or from right to left, that is, the target window supports a horizontal sliding mode, the horizontal distance between each placeholder picture and the center of the target window is obtained in real time; or if the sliding direction of the sliding operation event is a vertical direction from top to bottom or from bottom to top, that is, the target window supports a vertical sliding manner, the vertical distance between each placeholder picture and the center of the target window is obtained in real time. The horizontal distance is an absolute value of a difference value between a first abscissa corresponding to the center of the placeholder picture and a second abscissa corresponding to the center of the target window, and the vertical distance is an absolute value of a difference value between a first ordinate corresponding to the center of the placeholder picture and a second ordinate corresponding to the center of the target window. In specific implementation, the distance reference can be determined by acquiring the sliding direction supported by the target window, so that the error in acquiring the distance is avoided. Hereinafter, the description will be mainly made in a manner that the target window supports horizontal movement.

After the space is obtained, according to the sequence from small to large of the space, the occupied pictures with the changed occupied sizes in the subsequent moving process are determined and serve as the occupied pictures to be adjusted, namely, the pictures with the changed occupied sizes of the occupied pictures are selected. During specific implementation, the number of the placeholder pictures with changeable placeholder sizes in the moving process can be determined according to the number of the placeholder pictures in the target window and the size change condition of the placeholder pictures during static display, and then after the space size is obtained, the placeholder pictures with the number can be selected according to the sequence from small to large to determine as the placeholder pictures to be adjusted. Still taking fig. 3 as an example, the target window includes 5 placeholder pictures, and the total size of the 5 placeholder pictures is 3 different sizes when the placeholder pictures are statically displayed, wherein the sizes of the symmetric positions are the same, so that it can be determined that the placeholder pictures with the sizes changing in the moving process are 4. If a group of placeholder pictures with smaller sizes is added on the left side and the right side of the target window in fig. 3, 6 placeholder pictures which can change in the moving process can be determined; if a group of placeholder pictures with the same size as the outermost side are added on the left side and the right side of the target window in fig. 3, it can be determined that the number of placeholder pictures which can be changed in the moving process is 4.

Or after the space is acquired, a space interval corresponding to the placeholder picture to be adjusted can be set according to the number of placeholder pictures in the target window, the size change condition of the placeholder pictures during static display and the position condition of the placeholder pictures during static display, then the space is matched with the space interval aiming at the space of any placeholder picture acquired in real time, if the space is in the space interval, the placeholder picture is determined to be the placeholder picture to be adjusted, and if the space is not in the space interval, the placeholder picture is not adjusted. Still taking fig. 3 as an example, assuming that the placeholder picture 3 is displayed at the central position before responding to the sliding operation event, that is, the distance is 0, the lower limit of the distance interval can be set to 0, and the upper limit is: the absolute value of the difference between the abscissa corresponding to the center point of the

placeholder picture

1 or 5 and the abscissa corresponding to the center of the target window when the placeholder picture is statically displayed.

More particularly, in the case where the center point of the placeholder picture at the middle position passes through the center line of the target window (the vertical center line if horizontal sliding is supported, or the horizontal center line if vertical sliding is supported), at least two placeholder pictures to be adjusted are selected from the plurality of placeholder pictures according to the size of the space and in combination with the sliding direction of the sliding operation event. For the above situation, since the placeholder pictures on the two sides are symmetrical, it is necessary to determine which placeholder pictures have the changed placeholder sizes by combining the sliding directions, and still take the static display position corresponding to fig. 3 as an example, that is, the placeholder pictures are integrally moved to the right to the position where the central point of the placeholder picture 3 passes through the vertical center line of the target window, and at this time, it is necessary to determine that the placeholder pictures to be adjusted are 3 and 4 instead of 3 and 2 by combining the sliding directions from right to left.

Step S430: acquiring the placeholders of the at least two placeholder pictures to be adjusted in real time, performing cooperative adjustment processing on the placeholders of the at least two placeholder pictures to be adjusted, and keeping the placeholders of other placeholder pictures except the placeholder pictures to be adjusted unchanged.

Specifically, the placeholder pictures to be adjusted are subjected to scaling adjustment processing and translation adjustment processing, so that the distances between the adjacent placeholder pictures to be adjusted and between the placeholder picture to be adjusted and other adjacent placeholder pictures are kept unchanged.

Further, in some optional embodiments of the present invention, in order to avoid an influence on other placeholder pictures, the coordination processing is performed by: and determining a minimum external rectangle of the whole area formed by the at least two placeholder pictures to be adjusted, performing cooperative adjustment processing on the placeholder sizes of the at least two placeholder pictures to be adjusted in the minimum external rectangle, and performing cooperative adjustment processing in the minimum external rectangle to achieve the effect of eliminating the length of the placeholder, so as to keep the size of the minimum external rectangle unchanged and not influence other placeholder pictures. For example, if the sliding operation is horizontal sliding, the distance between the left edge and the right edge of the minimum bounding rectangle can be kept unchanged during the moving process, and thus other placeholder pictures on the two sides are not affected.

On the basis of the optional embodiment, in order to further accurately adjust the placeholder size of the placeholder picture to be adjusted, a mapping relation between the position of the placeholder picture and the placeholder size can be established in advance; and the occupation size in the mapping relation is in a trend of becoming smaller from the center position of the target window to two sides. And then, when the size of the placeholder pictures to be adjusted in the minimum external rectangle is adjusted, performing coordinated adjustment processing on the placeholder sizes of the at least two placeholder pictures to be adjusted in the minimum external rectangle according to the mapping relation, wherein the real-time positions of the placeholder pictures to be adjusted can be reflected through the space, combining the mapping relation to obtain the placeholder sizes of the placeholder pictures to be adjusted, namely obtaining an adjusted target, and adjusting the placeholder pictures to be adjusted to obtain the placeholder sizes. It should be noted that, in order to ensure that the distance between adjacent placeholder pictures to be adjusted is not changed, the placeholder pictures to be adjusted need to be adjusted in a translation manner in the process of performing the scaling adjustment.

Further, in the process of performing the cooperative adjustment processing, the adjustment may be performed in the minimum bounding rectangle in order from two sides to the middle, or from one side to the other side. Wherein, the process of adjusting from one side to the other side is roughly as follows: from one side in the minimum circumscribed rectangle, the occupation size of the first occupation picture to be adjusted is firstly zoomed according to the mapping relation, and then the distance between the second occupation picture to be adjusted and the first occupation picture to be adjusted is adjusted to keep the distance unchanged; then, the scaling process is performed on the size of the second placeholder picture to be adjusted, the distance … … between the third placeholder picture to be adjusted and the second placeholder picture to be adjusted is adjusted, and so on, so that the adjustment in the whole minimum circumscribed rectangle can be completed. And the process of adjusting from two sides to the middle is the same as the process, namely the zooming processing and the translation processing are performed alternately, so that the distance is kept unchanged while the requirement of size zooming is met.

Step S440: and covering and displaying the pictures to be displayed with corresponding sizes on the placeholder pictures according to the placeholder sizes of the placeholder pictures.

The picture to be displayed is always displayed on the placeholder picture in a covering manner, and the picture to be displayed can be moved and zoomed to be displayed along with the movement and the zooming of the placeholder picture in the process of the cooperative adjustment processing.

And, in some optional embodiments of the invention, to ensure that the pitch does not strictly remain changed, the picture to be displayed with the same footprint size is overlaid on each placeholder picture.

Step S450: and aiming at any picture to be displayed, setting a covering effect for the picture to be displayed according to the distance between the position-occupying picture covered by the picture to be displayed and the center of the target window.

Specifically, by setting different masking effects according to the distance, the picture to be displayed in the middle position can be highlighted. Each picture to be displayed is provided with a covering layer, the transparency of each picture to be displayed is independently set, the transparency is set between 0 and 1, preferably, the excessive darkness of the picture display is not avoided, and the transparency can be set between 0.5 and 1, wherein the higher the transparency value is, the less obvious the covering effect is, the clearer the picture to be displayed is, and on the basis of the transparency, the transparency of the covering layer can be gradually reduced from the middle to the two sides.

It should be noted that, in the foregoing embodiment, the description is mainly performed in a sliding manner of horizontal sliding, but the present invention is not limited thereto, and in some other embodiments, the sliding manner may also be in a vertical direction, and the implementation principle and process thereof are similar to horizontal sliding, and are not described again here.

According to the picture sliding display method provided by the embodiment, in the process of monitoring the sliding operation event and responding to the sliding operation event, the distance between each placeholder picture and the center of the target window is obtained in real time, the size of the distance can reflect whether the placeholder picture is subjected to size change in the process of continuously moving, and on the basis, the placeholder picture to be adjusted is selected according to the size of the distance; then, carrying out cooperative adjustment processing on the placeholder pictures to be adjusted, specifically, adjusting in a minimum external rectangle of an overall area formed by the placeholder pictures to be adjusted so as to avoid influencing other placeholder pictures, wherein the basis of zooming adjustment is mainly a pre-established mapping relation between positions and placeholder sizes, so that the placeholder pictures to be adjusted can be accurately adjusted to corresponding sizes in each position, and translation adjustment is carried out while zooming adjustment is carried out so as to ensure that the distance between the placeholder pictures to be adjusted is kept unchanged; meanwhile, the occupied sizes of other occupied pictures are kept unchanged, so that the distance between other occupied pictures can be kept unchanged, and finally, the distance between every two adjacent occupied pictures is kept unchanged; in addition, a masking effect is set for each picture to be displayed, so that the picture in the middle is highlighted.

Fig. 5 is a flowchart illustrating a picture sliding display method according to another embodiment of the present invention. In this embodiment, a case that the placeholder pictures statically displayed in the target window have only two sizes is mainly described, where the placeholder picture statically displayed in the central position is of a first size, and the placeholder pictures statically displayed in the rest positions are of a second size, where static display refers to display in a non-sliding process, that is, when a sliding operation event is not responded. As shown in fig. 5, the method comprises the steps of:

step S510: monitoring a sliding operation event in a target window; a plurality of placeholder pictures are set in the target window.

Step S520: in the process of responding to the sliding operation event, the distance between each placeholder picture and the center of the target window is obtained in real time; two to-be-adjusted placeholder pictures with the minimum distance are selected from the plurality of placeholder pictures.

Specifically, corresponding to the situation that the placeholder pictures statically displayed in the target window have only two sizes, two placeholder pictures with the minimum distance are selected from the plurality of placeholder pictures and determined as the placeholder pictures to be adjusted. In practice, for this case, the size change occurs only during the movement of the middle placeholder picture to the adjacent placeholder picture on either side, or during the movement of the adjacent placeholder picture on either side to the middle placeholder picture. As can be seen from the description of step S420 in the embodiment corresponding to fig. 4, the placeholder pictures to be adjusted can be determined as the two placeholder pictures with the closest space according to the order of the spaces from small to large or according to the space interval of the set region to be adjusted, and the specific principle refers to the description of step S420. In addition, for the condition that the central point of the placeholder picture at the middle position passes through the central line of the target window, two placeholder pictures to be adjusted can be determined by combining the sliding direction.

To facilitate an understanding of the present embodiments, a specific example is described below:

fig. 6a shows a schematic diagram of a situation where the statically displayed placeholder picture has only two sizes in one specific example. As shown in fig. 6a, when the placeholder picture 3 is located at the center position during static display, the placeholder size is the largest and is the first size, and the placeholder sizes of the remaining

placeholder pictures

1,2,4, and 5 are all the same and are the second size, if a sliding operation with a sliding direction to the right is received, at the starting time of the sliding operation, the placeholder picture 3 is closest to the distance, the placeholder pictures 2 and 4 are next closest to each other, and by combining the sliding direction to the right, it can be determined that only 4 placeholders exist for the placeholder pictures with the changed placeholder sizes in the placeholder pictures 2 and 4, thereby determining that the two placeholder pictures to be adjusted are the placeholder pictures 3 and 4.

Step S530: acquiring the occupation sizes of the two occupation pictures to be adjusted in real time, carrying out cooperative adjustment processing on the occupation sizes of the two occupation pictures to be adjusted, and keeping the occupation sizes of other occupation pictures except the occupation pictures to be adjusted unchanged.

Further, in an optional manner of implementing the cooperative adjustment processing by the minimum circumscribed rectangle, the adjustment process is as follows: determining the minimum external rectangle of the whole area formed by the two occupancy pictures to be adjusted,

in the minimum circumscribed rectangle, the occupation size of the first occupation picture to be adjusted is adjusted in a scaling mode, including the width and height of the first occupation picture to be adjusted, according to the mapping relation between the position of the occupation picture and the occupation size of the first occupation picture to be adjusted, the first occupation picture to be adjusted can be any one of the two occupation pictures to be adjusted, namely, the occupation size of the first occupation picture to be adjusted at the position is obtained according to the real-time position inquiry mapping relation, and then scaling adjustment is carried out. According to the adjustment result of the occupation size of the first occupation picture to be adjusted, carrying out translation processing on the second occupation picture to be adjusted so as to enable the distance between two adjacent sides of the two occupation pictures to be adjusted (namely the distance between the two occupation pictures to be adjusted) to be consistent with the distance before adjustment, after the first occupation picture to be adjusted is zoomed and adjusted, changing the distance between the two occupation pictures to be adjusted, and keeping the distance unchanged by translating the second occupation picture to be adjusted; and adjusting the translated second placeholder picture to be adjusted according to an adjustment mode opposite to the zooming adjustment of the first placeholder picture, so that the distance between two separated sides of the two placeholder pictures to be adjusted is consistent with that before adjustment, wherein if the width (height if vertical sliding) of the first placeholder picture to be adjusted is reduced (increased) by the first size, the width (height if vertical sliding) of the second placeholder picture to be adjusted is increased (reduced) by the first size, and according to the width adjustment, the height of the second placeholder picture to be adjusted is zoomed and adjusted in the same proportion.

Fig. 6b shows the schematic representation after a distance to the right corresponding to fig. 6 a. In the process of changing fig. 6a to 6b, the size of the minimum bounding rectangle remains unchanged all the time, and in fig. 6b, compared to fig. 6a, the placeholder size of the placeholder picture 3 is increased, and the placeholder size of the placeholder picture 4 is decreased, and a specific coordination adjustment processing procedure in the process is as follows: in the sliding process, a distance x corresponding to the placeholder picture 3 and a maximum width difference value w (namely the width is reduced by w) between the width after being scaled according to the mapping relation and the central position are calculated through scaleView (namely the width is reduced by w), and then the position of the placeholder picture 4 on the x axis is set to move to the left by x + w through layout SubViews (view: ZYScaleBaseShell, viewAt index: Integer), so that the distance between the placeholder picture 3 and the placeholder picture 4 is ensured to be unchanged; then, the width increase w of the placeholder picture 4 is set in the layout SubViews method (the scaling adjustment of the placeholder picture 3 is opposite), and meanwhile, the height is amplified in an equal proportion, so that the distance between the left side of the placeholder picture 3 and the right side of the placeholder picture 4 is unchanged, namely the width of the minimum circumscribed rectangle is kept unchanged, and the distance between the placeholder picture 3 and the placeholder picture 2 on the left side of the placeholder picture, and the distance between the placeholder picture 4 and the placeholder picture 5 on the right side are further ensured to be unchanged. On the basis, the occupied sizes of the other

occupied pictures

1,2 and 5 in the moving process are kept unchanged, and finally the distance between any two adjacent occupied pictures is ensured to be unchanged.
