In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, a schematic flow chart of a primitive transformation method provided in an embodiment of the present application is shown, where the method includes:
step S11, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
in the embodiment of the application, the primitive is firstly opened in the target display area, so that the content of the primitive is displayed in the target display area. The target display area includes a plurality of first initial boundaries and the graphical element includes a plurality of second initial boundaries.
In a possible implementation manner of the embodiment of the application, after the primitive is opened, the size of the primitive exceeds the target display area, and at least one second initial boundary is outside the target display area. In another possible implementation manner, the primitive size is smaller than the target display area, and the whole primitive is located in the target display area, and the plurality of second initial boundaries are all located in the target display area.
In the embodiments of the present application, the shapes of the target display area and the primitive are used as rectangles for example, and it should be understood that the shapes of the target display area and the primitive are rectangles only for convenience of description and understanding, and are not limited, and the target display area and the primitive may be any shapes.
Step S12, acquiring a first input aiming at the graphic primitive, transforming the graphic primitive according to the input parameters included in the first input, determining a first target boundary from a plurality of first initial boundaries, and determining a second target boundary from a plurality of second initial boundaries;
in the embodiment of the present application, for a dragging input of a primitive, or click data of a control for controlling a primitive to be scaled or selected, a primitive is shifted, scaled, or rotated according to an input parameter including, but not limited to, a moving direction, a scaling multiple, or a rotating direction. At this time, a first target boundary is determined from the plurality of first initial boundaries according to the actual situation, and a second target boundary is determined from the plurality of second initial boundaries.
For example, the primitive receives the move command, and moves according to the move direction, and if the second initial boundaries are all located within the target display area at this time, the move direction is moving upward. A first initial boundary above the target display area is determined as a first target boundary and a second initial boundary above the graphical element is determined as a second target boundary. And when the moving direction is downward, determining a first initial boundary below the target display area as a first target boundary, and determining a second initial boundary below the graphic element as a second target boundary. And in the process of converting the moving graphic element, the second target boundary can be overlapped with or separated from the first target boundary.
In step S13, when there is coincidence between the first object boundary and the second object boundary, the conversion of the primitive is terminated.
In this embodiment of the present application, or in a case where the second target boundary collides with the first target boundary, that is, the first target boundary and the second target boundary coincide with each other, the transformation of the primitive is ended. For example, when the primitive is entirely located in the target display area and moves upward, the movement of the primitive is ended when the second initial boundary above the primitive coincides with the first initial boundary of the target display area. The graphics primitives can not move upwards continuously, so that part of the graphics primitive contents move out of the target display area, and the waste of the display area is avoided.
The primitive transformation method provided by the embodiment of the application displays the primitive in the target display area, and transforms the primitive according to the first input parameter; determining a first target boundary from a plurality of first initial boundaries of a target display area, and determining a second target boundary from a plurality of second initial boundaries of a display primitive; and under the condition that the first target boundary and the second target boundary are overlapped, finishing the transformation of the primitive. The graphics primitives can be displayed in the target display area to the maximum extent when being changed, waste of the display area is avoided, and the graphics primitive changing effect is better.
When intersection coordinate information exists between the second target coordinate set and the first target coordinate set, the situation that the first target boundary and the second target boundary are overlapped is described.
In an example, the target display area may be a display area of the entire display screen, or a part of the display area may be selected as the target display area in the display screen.
Referring to fig. 2, a flowchart of a primitive transformation method provided in a second embodiment of the present disclosure is shown, in which a primitive portion is displayed in a target display area and an input parameter includes a moving direction, and the primitive transformation method includes:
step S21, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
step S22, moving the graphics primitive according to the moving direction, determining a first initial boundary of the target display area opposite to the moving direction as a first target boundary, determining a second initial boundary of the graphics primitive opposite to the moving direction as a second target boundary, and the second target boundary is located outside the target display area;
in step S23, when there is coincidence between the first object boundary and the second object boundary, the conversion of the primitive is terminated.
Step S21 is the same as step S11, and step S23 is the same as step S13, which are not repeated herein. The difference from the first embodiment is that step S22 is detailed as follows:
and opening the graphics primitives in the target display area, and when the size of the graphics primitives is larger than the target display area, namely part of the graphics primitives is displayed in the target display area, and the other part of the graphics primitives is positioned outside the target display area. At this time, only partial primitive information can be displayed, and the primitive can be dragged to move in order to obtain the primitive information outside the target display area.
For example, when the right side of the primitive is outside the target display region, the primitive needs to be moved to the left to display the content of the primitive on the right side. At this time, a first initial boundary of the target display area opposite to the moving direction is determined as a first target boundary, a second initial boundary of the graphics primitive opposite to the moving direction is determined as a second target boundary, and the second target boundary is located outside the target display area. The direction of movement is to the left, i.e. the boundary to the right of the target display area is determined as the first target boundary and the rightmost boundary where the icon is outside the target display area is determined as the second target boundary.
And moving the primitive leftwards, and stopping moving the primitive leftwards continuously under the condition that the second target boundary of the primitive is overlapped with the first target boundary. At this time, if the upper and lower sides or the left side of the primitive is outside the target display area, the primitive may be moved downward, upward or rightward according to the same operation.
The size of the primitive exceeds the target display area, the content exceeding the display part can be dragged and checked, the boundary of the primitive is limited to be dragged into the target display area, the primitive is prevented from exceeding the display part by dragging, the part needing to be displayed is displayed as far as possible to the maximum, and the primitive is displayed in the target display area to the maximum.
Referring to fig. 3, which is a schematic flow chart of a primitive transformation method provided in a third embodiment of the present application, in this embodiment, a whole primitive is located in a target display area, and an input parameter includes a moving direction, and the primitive transformation method includes:
step S31, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
step S32, moving the graphics primitive according to the moving direction, determining a first initial boundary of the target display area consistent with the moving direction as a first target boundary, determining a second initial boundary of the graphics primitive consistent with the moving direction as a second target boundary, and the second target boundary is located in the target display area;
in step S33, when there is coincidence between the first object boundary and the second object boundary, the conversion of the primitive is terminated.
Step S31 is the same as step S11, and step S33 is the same as step S13, which are not repeated herein. The difference from the first embodiment is that step S32 is detailed as follows:
and opening the graphics primitives in the target display area, and when the size of the graphics primitives is smaller than that of the target display area, the graphics primitives are wholly positioned in the target display area, and the graphics primitives can be dragged randomly in the target display area to move.
For example, when moving the primitive to the left, a first initial boundary of the target display area coinciding with the moving direction is determined as a first target boundary, a second initial boundary of the primitive coinciding with the moving direction is determined as a second target boundary, and the second target boundary is located within the target display area. The direction of movement is to the left, i.e. the boundary to the left of the target display area is determined as the first target boundary and the boundary to the leftmost of the primitive is determined as the second target boundary.
And moving the primitive leftwards, and stopping moving the primitive leftwards continuously under the condition that the second target boundary of the primitive is overlapped with the first target boundary. At this time, if the upper and lower sides or the right side of the primitive are located within the target display area and do not coincide with the boundary corresponding to the target display area, the primitive may be moved upward, downward, or rightward according to the same operation.
And adding a primitive in the target display area, detecting whether boundary collision occurs when the upper, lower, left and right boundaries of the primitive are close to the boundary of the target display area when the primitive is moved, and if the boundary of the primitive is overlapped with the boundary of the target display area, the primitive cannot be moved continuously. The problem of display area waste caused by the fact that the moving graphics primitives exceed the boundary of the target display area is solved, and the graphics primitives are guaranteed to be displayed in the target display area to the maximum extent.
Referring to fig. 4, which is a schematic flow chart of a primitive transformation method provided in a fourth embodiment of the present disclosure, in the present embodiment, a primitive portion is displayed in a target display area, and an input parameter includes a moving direction, and the primitive transformation method includes:
step S41, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
step S42, moving the graphics primitive according to the moving direction, determining a first initial boundary of the target display area opposite to the moving direction as a first target boundary, determining a second initial boundary of the graphics primitive opposite to the moving direction as a second target boundary, and the second target boundary is located outside the target display area;
in step S43, when there is coincidence between the first object boundary and the second object boundary, the movement of the primitive in the movement direction is terminated.
Step S41 is the same as step S21, and step S42 is the same as step S22, which are not repeated herein. The difference from the second embodiment is that step S43 is detailed as follows:
for example, when the right side of the primitive is outside the target display area, the primitive needs to be moved to the left to display the content of the primitive on the right side, and when the second target boundary of the primitive coincides with the first target boundary, the primitive is stopped from being moved to the left. At this time, if the upper side or the lower side or the left side of the primitive is located outside the target display area, the primitive can be continuously moved downwards, upwards or rightwards until the first target boundary corresponding to the moving direction is overlapped with the second target boundary, and then the moving in the moving direction is stopped. The flexibility of primitive transformation is increased, and the primitive transformation effect is better.
Referring to fig. 5, which is a schematic flow chart of a primitive transformation method provided in a fifth embodiment of the present application, in this embodiment, a whole primitive is located in a target display area, and an input parameter includes a moving direction, where the primitive transformation method includes:
step S51, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
step S52, moving the graphics primitive according to the moving direction, determining a first initial boundary of the target display area consistent with the moving direction as a first target boundary, determining a second initial boundary of the graphics primitive consistent with the moving direction as a second target boundary, and the second target boundary is located in the target display area;
in step S53, when there is coincidence between the first object boundary and the second object boundary, the movement of the primitive in the movement direction is terminated.
Step S51 is the same as step S31, and step S52 is the same as step S32, which are not repeated herein. The difference from the third embodiment is that step S53 is detailed as follows:
for example, moving the primitive to the left, and stopping moving the primitive to the left when the second target boundary of the primitive coincides with the first target boundary. At this time, if the upper side and the lower side or the right side of the primitive are positioned in the target display area and do not coincide with the boundary corresponding to the target display area, the primitive can be continuously moved upwards, downwards or rightwards until the first target boundary corresponding to the moving direction coincides with the second target boundary, and the moving in the moving direction is stopped. The flexibility of primitive transformation is increased, and the primitive transformation effect is better.
Referring to fig. 6, which is a schematic flow chart of a primitive transformation method provided in a sixth embodiment of the present application, in this embodiment, the input parameter further includes a scaling multiple, and the primitive transformation method includes:
step S61, displaying a graphic element in a target display area, wherein the target display area comprises a plurality of first initial boundaries, and the graphic element comprises a plurality of second initial boundaries;
step S62, zooming the graphics primitive according to the zooming times, determining all the first initial boundaries of the target display area as first target boundaries, and determining all the second initial boundaries of the graphics primitive as second target boundaries;
in step S63, when there is an overlap between any mutually opposite first object boundary and second object boundary, the scaling of the primitive is ended.
Step S61 is the same as step S11, and is not described herein. The difference from the first embodiment is that steps S62 and S63 are detailed as follows:
in addition to moving the primitives, the primitives may be scaled according to a scaling factor. In this embodiment of the present application, when the input parameter includes the moving direction, and the primitive is transformed according to the moving direction as described in the above embodiment, and after the movement of the primitive in the moving direction is completed, the primitive may be further scaled according to the scaling factor.
After the primitive is moved, when the size of the primitive exceeds the target display area, the primitive can be reduced, at the moment, four edges of the primitive are all used as second target boundaries, and four edges of the target display area are used as corresponding first target boundaries. And when the upper and lower two opposite second target boundaries of the primitive coincide with the upper and lower two first target boundaries of the target display area respectively, or when the left and right two opposite second target boundaries of the primitive coincide with the left and right two first target boundaries of the target display area respectively, ending the reduction operation on the primitive. So as to ensure that the graphic element is maximally displayed in the target display area.
After the primitive is moved, the size of the primitive is smaller than that of the target display area, when the whole primitive is located in the target display area, the primitive can be amplified, at the moment, four edges of the primitive are all used as second target boundaries, and four edges of the target display area are used as corresponding first target boundaries. And finishing the enlarging operation of the primitive when the upper and lower two opposite second target boundaries of the primitive coincide with the upper and lower two first target boundaries of the target display area respectively, or when the left and right two opposite second target boundaries of the primitive coincide with the left and right two first target boundaries of the target display area respectively. The waste of a display area is avoided, and the graphics primitives are guaranteed to be displayed in the target display area to the maximum extent.

in step S73, when there is an overlap between any mutually opposite first object boundary and second object boundary, the scaling of the primitive is ended.
Step S71 is the same as step S11, and is not described herein. The difference from the first embodiment is that steps S72 and S73 are detailed as follows:
besides moving and scaling the primitive, the primitive can be rotated according to the rotation direction. In this embodiment of the application, when the input parameter includes the moving direction, and the primitive is transformed according to the moving direction as described in the above embodiment, and after the movement of the primitive in the moving direction is completed, the primitive may be further continuously rotated according to the rotating direction.
After moving the primitive, when the size of the primitive exceeds the target display area, the primitive can be reduced after being rotated, four edges of the rotated primitive are all used as second target boundaries, and four edges of the target display area are used as corresponding first target boundaries. And when the upper and lower two opposite second target boundaries of the primitive coincide with the upper and lower two first target boundaries of the target display area respectively, or when the left and right two opposite second target boundaries of the primitive coincide with the left and right two first target boundaries of the target display area respectively, ending the reduction operation on the primitive. So as to ensure that the graphic element is maximally displayed in the target display area.
After the primitive is moved, the size of the primitive is smaller than that of the target display area, when the whole primitive is located in the target display area, the primitive can be amplified after being rotated, four edges of the primitive are all used as second target boundaries, and four edges of the target display area are used as corresponding first target boundaries. And finishing the enlarging operation of the primitive when the upper and lower two opposite second target boundaries of the primitive coincide with the upper and lower two first target boundaries of the target display area respectively, or when the left and right two opposite second target boundaries of the primitive coincide with the left and right two first target boundaries of the target display area respectively. The waste of a display area is avoided, and the graphics primitives are guaranteed to be displayed in the target display area to the maximum extent.
