Description

Icon processing method and device and terminal

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an icon processing method, an icon processing device, and a terminal.

Background

Along with the generation of mobile intelligent terminals such as smart phones and tablet computers, mobile operating systems such as iOS (interactive operating system) and Android (Android) appear. An application program, often referred to as an application or app, runs on the mobile operating system. The icons of the applications are often designed as rounded icons, i.e. the four corners of a square are rounded. Because the Android system of one of the two mobile operating systems has no uniform specification for the design of the icons, the design styles of the icons provided by developers of various applications are not uniform. When presented on a mobile smart terminal or in an application marketplace, icons of different styles can cause a visually cluttered experience.

In order to make various icons with different styles have an attractive effect when being presented, manufacturers of mobile intelligent terminals or managers of application markets often perform uniform processing on the icons. For example, some vendors redraw icons for various applications, but this approach ignores the design intent of the developer and is costly and impossible to cover all applications. Some manufacturers require developers to provide icons meeting their requirements, but the different requirements of different manufacturers make the developers need to provide different versions, which increases the cost of design and maintenance. Some manufacturers uniformly cut icon versions provided by developers, but due to the difference of icon styles, the simple cutting often causes blank gaps to be left in the cut icon corners, so that the cut icon versions are not beautiful enough.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may 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 disclosure to those skilled in the art.

Among the various applications provided by application developers, the icons of the applications have various shapes, such as square, generally rectangular, circular, oval, etc., and other special shapes. When the application icons are presented, for example, on a smart phone desktop or in an application market, the icons in various shapes can cause a visually disordered feeling to a user if not processed. In order to make the various icons have an attractive and uniform effect when being presented, a smart phone manufacturer or an application market manager usually processes the various icons to a certain extent. There are two treatment regimes in common use today: replacing icon resources and direct cropping. One example of an alternative icon resource scheme is an application market that provides for the application icons uploaded by developers to be rounded off, which has the disadvantage that the icon style of applications downloaded and installed by users through other application markets is not consistent with that downloaded and installed in the application market, and another example is from Android7.1, which allows developers to set icons of another style through special fields for mobile phone calls, which has the disadvantage that if the developers do not make corresponding settings, or the applications are developed on a lower Android version, the style uniformity is still not achieved. The scheme of direct cropping is to carry out uniform rounding processing on four corners of the icon, and the scheme can carry out uniform processing without omission no matter whether a developer provides a rounded icon or not.

In a specific practical process, the inventor of the invention finds that in the prior art, the direct cropping method is likely to have the situation of incomplete treatment on nonstandard icons. For example, an icon may have a fillet, but the fillet is larger than the fillet of the required size, and direct cropping may not result in an icon with a fillet of the required size, leaving blank gaps at four corners when the icon is displayed, and for example, an icon may be slightly smaller than an icon of a normal size, and direct cropping may also result in insufficient processing, leaving blank gaps at corners.

Based on this, the inventor of the present invention provides an icon processing method, which first identifies icons that may produce missing gaps, then performs appropriate preprocessing on such icons, and finally cuts rounded corners of the required size. Compared with a method for replacing icon resources, the method does not depend on additional icons, is beneficial to reducing the cost of design and maintenance of developers, and saves the storage space of equipment.

Fig. 1 is a flowchart of a first embodiment of an icon processing method according to the present invention. As shown in fig. 1, the method comprises the steps of:

step 101: an icon of an application program is acquired.

The acquiring the icon of the application program comprises the following steps:

the method comprises the steps of obtaining system permissions of operation icons in terminal equipment, wherein the terminal equipment comprises a smart phone, a tablet personal computer, a desktop computer, a smart watch, intelligent control equipment and the like, and the system permissions of the operation icons comprise system permissions for modifying icons and system permissions for replacing the icons;

acquiring an icon list of each application program in terminal equipment, wherein the icon list usually comprises icons with different sizes;

at least one icon to be modified is determined in the icon list of each application program, and the size of the icon to be modified is generally matched with the required size or is slightly smaller than the required size.

Step 102: and determining a maximum rounding icon area inside the effective area of the icon, wherein the maximum rounding icon area is the icon area with the largest area which meets the requirement of rounding according to the preset value of the radius of curvature of the rounding.

The effective area of the icon refers to an area where the icon has meaningful content, the icon can be designed conventionally or designed unconventionally, the icon is designed conventionally and is generally a rounded icon, the shape of the icon is formed by rounding four corners of a square, the actual icon is contained in a rectangular canvas, and the effective area of the icon is the area of the actual icon.

The maximum rounded icon area is the largest rounded icon area that satisfies the size of the rounded corner, i.e., the radius of curvature is the required size, and is completely included in the icon effective area.

Step 103: and cutting the area except the maximum rounded icon area in the icon.

And after the maximum rounding icon area is determined, shearing the area except the maximum rounding icon area, and only reserving the maximum rounding icon area.

The cutting processing is to delete all pixels of the selected area through a certain step program.

In the embodiment of the invention, the maximum rounding icon area in the icon effective area is determined, and the pixels outside the area are deleted, so that the rounding size of the obtained icon is ensured to be the required size, and the meaningful content of the original icon is retained to the maximum extent.

Fig. 2 is a flowchart of determining a maximum rounded icon area in an icon effective area in a second embodiment of an icon processing method according to the embodiment of the present invention. As shown in fig. 2, determining the largest rounded icon area within the icon active area includes the steps of:

step 201: and determining the effective area of the icon.

The determination of the effective area of the icon can be performed by detecting the icon through a certain step, or displaying the icon on a screen and manually defining an area with meaningful content.

Step 202: and searching all rounding icon areas meeting the requirement of rounding according to the radius of curvature of the rounding as a preset value in the effective area of the icon.

For example, a smaller square is arbitrarily chosen and rounded within the icon, the size of the rounded corner being the desired size, resulting in a rounded icon area. According to the method, all the rounded icon areas which satisfy the condition that the rounding is the required size and are contained in the icon effective area can be found out.

Step 203: and determining a rounded icon area with the largest area from all the found rounded icon areas.

For example, a rounded icon area is taken in a conventional icon, the center of the rounded icon area coincides with the center of the icon, four sides of the rounded icon area are parallel to four sides of the icon, the area is gradually enlarged, and the size of the rounded corner is kept unchanged until the rounded icon area is in contact with the boundary of the effective area of the icon.

In the embodiment of the invention, the effective content of the original icon is reserved to the maximum extent by searching the largest one of all the rounded icon areas which are contained in the icon effective area and have the required rounded angle size.

Fig. 3 is a flowchart illustrating an icon processing method according to a third embodiment of the present invention, wherein the area of the icon other than the area of the icon with the largest rounded corner is cut. As shown in fig. 3, the clipping process for the area of the icon except for the area of the icon with the largest rounded corner includes the following steps:

step 301: and cutting transparent areas on four edges of the icon.

The transparent area is an area in which the transparency values of all pixel points in the area are higher than a preset transparency threshold.

Step 302: transparent areas on the four corners of the icon are clipped.

Step 303: and rounding according to the preset value of the radius of curvature of the rounding.

In the embodiment of the invention, the transparent areas at the four sides and the four corners of the icon are cut, and then the rounding treatment is carried out, so that the rounding of the processed rounded icon is ensured to be the required size, and no blank gap is left.

Fig. 4 is a flowchart of cutting transparent areas on four edges of an icon according to a fourth embodiment of an icon processing method according to the present invention. As shown in fig. 4, cutting transparent areas on four sides of the icon includes the following steps:

step 401: and detecting actual boundary lines of the icon in the four-edge direction.

Step 402: and acquiring the distance between the actual boundary line and the corresponding edge of the icon.

Step 403: and when the distance meets the preset standard, determining the range of the sheared square according to the detected actual boundary lines in the four directions.

Step 404: and cutting the icon according to the square range.

In the embodiment of the invention, the invalid contents on the four sides of the icon are removed by detecting the actual boundary lines in the four sides of the icon, determining the minimum square area containing the valid contents of the icon, and cutting the pixels outside the area.

Fig. 5 is a flowchart of cutting transparent areas on four sides of an icon according to a fifth embodiment of an icon processing method according to an embodiment of the present invention. As shown in fig. 5, cutting transparent areas on four sides of the icon includes the following steps:

step 501: and reading the icon.

Step 502: straight edges are detected from the four edges of the icon, respectively, in a direction perpendicular to and inward of the edges.

The straight edge refers to a straight line parallel to the edge of the icon, namely a set of pixels with a certain abscissa or ordinate.

The straight edges are detected from the four edges of the icon in a direction perpendicular to the edges, e.g. starting with the top row, each row is detected row by row downwards, starting with the leftmost column, and each column is detected column by column to the right.

Step 503: and detecting the pixel points on the straight edge in sequence.

For example, each pixel point is detected one by one from left to right in each row.

Step 504: and judging whether the pixel points are transparent, if so, continuing to execute the step 503, otherwise, executing the step 505.

The transparency is that the transparency value of the pixel point is higher than a preset transparency threshold value, for example, the pixel point alpha value is lower than a certain value and is regarded as transparent.

Step 505: and continuously detecting a plurality of pixel points, judging whether the transparencies of the subsequent pixel points are the same as the pixel points, if so, executing the step 506, and otherwise, executing the step 507.

The detection continues for a number of pixels, for example, the number is equal to one sixth of the number of all pixels in the row.

If the transparency of these subsequent pixels is the same as the first detected opaque pixel, this row or column is considered to be one of the actual border lines of the icon.

If the transparency of one pixel point is different from that of the opaque pixel point detected in the subsequent process of detecting a plurality of pixel points, the actual boundary line of the part of the icon is not a straight line but a designed pattern, and at the moment, the edge of the icon is used as the actual boundary line of the part.

Step 506: the distance between the straight edge and the edge of the icon corresponding to the straight edge is obtained, and then step 508 is performed.

For example, the line number of the top line is recorded as 0, the line number is incremented by 1 every time one line is added when the top line is searched downward line by line, and the line number of the actual boundary line on the upper part of the found icon is used as the distance between the actual boundary line on the upper part of the icon and the upper part of the icon.

Step 507: the distance between the straight edge and the edge of the icon corresponding to the straight edge is set to zero, and then step 506 is performed.

Step 508: and judging whether the distance is smaller than a preset value, if so, executing a step 509, otherwise, executing a step 513.

The distance is less than a predetermined value, for example, the distance between the left and right sides of the icon is referred to as the width of the icon, the distance between the left and right actual boundary lines of the icon is referred to as the actual width of the icon, the sum of the left and right gaps, or the difference between the width of the icon and the actual width is less than 22% of the actual width.

Step 509: and counting the standard deviation of the distances between the four straight sides and the corresponding sides.

The step of counting the standard deviation of the distances between the four straight edges and the corresponding edges means that the standard deviation of the four distances is calculated after the four distances of the upper side, the lower side, the left side and the right side are obtained.

Step 510: and judging whether the standard deviation is smaller than a preset value, if so, executing the step 511, and otherwise, executing the step 513.

If the standard deviation is larger than a preset threshold value, such as 2, it indicates that the four distances are different greatly, and the icon is not a conventional pattern but a specially designed pattern.

Step 511: a selectively retained square region is determined.

For example, a square is taken with the upper left vertex having an abscissa and an ordinate both equal to the smaller of the left and upper gaps and a side length equal to the larger of the actual width and actual height of the icon.

Step 512: deleting all pixels outside the square area.

Step 513: and saving the icon.

In the embodiment of the invention, a minimum square area containing the effective content of the icon is determined through specific steps, pixels outside the area are deleted, and the ineffective content on the four sides of the icon is removed.

Fig. 6 is a flowchart of cutting transparent areas at four corners of an icon according to a sixth embodiment of an icon processing method according to the present invention. As shown in fig. 6, cutting the transparent areas on the four corners of the icon includes the steps of:

step 601: actual boundary points at the four corners of the icon are detected.

Step 602: and acquiring the distance between the actual boundary point and the vertex of the icon corresponding to the actual boundary point.

Step 603: and when the distance meets a preset standard, determining the range of the sheared square according to a preset position and side length.

Step 604: and cutting the icon according to the square range.

In the embodiment of the invention, the minimum square area containing the effective content of the icon is determined by detecting the actual boundary points in the directions of the four corners of the icon and judging the distance between the points and the corresponding vertexes, and the pixels outside the area are cut, so that the ineffective content of the four corners of the icon is removed.

Fig. 7 is a flowchart of a method for processing an icon according to a seventh embodiment of the present invention, wherein transparent areas at four corners of the icon are cut. As shown in fig. 7, cutting the transparent areas on the four corners of the icon includes the steps of:

step 701: and reading the icon.

Step 702: and judging whether the icon is square, if so, executing step 703, and otherwise, executing step 711.

And judging whether the icon is square or not, namely judging whether the length and the width of the icon are equal or not.

Step 703: and sequentially detecting pixel points from the vertexes of the four corners of the icon to the center direction of the icon.

For example, starting from the top left vertex, each next pixel is a pixel whose row and column numbers are both incremented by 1.

Step 704: and judging whether the pixel points are transparent, if so, continuing to execute the step 703, and otherwise, executing the step 705.

Step 705: and acquiring the distance between the opaque pixel point and the vertex of the icon corresponding to the opaque pixel point.

Step 706: and judging whether the distance is smaller than a preset value, if so, executing a step 707, and if not, executing a step 711.

For example, the maximum value of the four gaps is compared with a preset value, the preset value is calculated according to the determined maximum rounded icon area, and specifically, the preset value is the minimum distance between one vertex of a square formed by four sides of the determined maximum rounded icon area and a corresponding rounded corner.

Step 707: and counting the standard deviation of the distances between the four opaque pixel points and the corresponding vertex points.

Step 708: and judging whether the standard deviation is smaller than a preset value, if so, executing a step 709, and otherwise, executing a step 711.

Step 709: and determining a square area selected and reserved according to the preset position and the side length.

And selecting the reserved square area to be a square formed by four sides of the determined maximum rounded icon area.

Step 710: deleting all pixels outside the square area.

Step 711: and saving the icon.

In the embodiment of the invention, through a certain specific step, the pixels outside the determined maximum rounded icon area are deleted, and the invalid contents of the four corners of the icon are removed.
