[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a first embodiment of the present invention proposes an image moving method. As shown in fig. 1, the image moving method includes, for example, steps S11 to S16.
Step S11: responding to a first operation of a user, and selecting a target image in a display image layer to obtain initial position information of the target image;
step S12: determining a target point in the target image to obtain initial position information of the target point;
step S13: obtaining the relative position information of the target point relative to the target image according to the initial position information of the target image, the initial position information of the target point and the zoom coefficient;
step S14: responding to a second operation of a user, and moving the target point in the display layer to obtain moving position information of the target point;
step S15: obtaining real-time position information of the target image according to the moving position information, the zooming coefficient and the relative position information of the target point;
step S16: and changing the position of the target image in the display layer according to the real-time position information of the target image.
Specifically, in step S11, the first operation mentioned is, for example, a mouse click operation or a button trigger operation on the target image. The initial position information of the target image is, for example, a position coordinate obtained by using the upper left corner point of the target image as a position point and according to the distance from the position point to the starting point of the display layer.
In step S12, the mentioned target point is located in the target image, and when the mouse is clicked within the target image, the corresponding click point is the target point. The mentioned initial position information of the target point is, for example, a position coordinate of the target point from a starting point of the display layer.
In step S13, the scaling factor is, for example, a scaling multiple of the display layer. The mentioned relative position information is, for example, the relative position coordinates of the target point with respect to the position point of the target image. Where the location point is for example the top left corner of the target image.
In step S14, the second operation mentioned includes, for example, a mouse drag operation. The mentioned moving position information of the target point is, for example, a position coordinate of the target point relative to a starting point of the display layer.
The real-time position information mentioned in step S15 is the position coordinates of the target image with respect to the starting point of the display layer.
Further, before step S11, the image shifting method according to the embodiment of the present invention further includes, for example: and carrying out scaling processing on the display layer, and taking the scaling multiple of the display layer as a scaling coefficient. The display layer that is not subjected to the scaling processing is, for example, 100% displayed, and the scaling processing is, for example, 25% displayed, 50% displayed, 75% displayed, 125% displayed, 150% displayed, or the like on the display layer. When the display layer is scaled, the corresponding length and width of the display layer are correspondingly changed, that is, the movable range of the target image is changed.
Further, before step S13, the image shifting method provided in this embodiment further includes, for example: and judging whether the display layer is subjected to scaling treatment or not, setting the scaling coefficient to be 1 when judging that the display layer is not subjected to scaling treatment, and taking the scaling multiple of the display layer as the scaling coefficient when judging that the display layer is subjected to scaling treatment. By judging whether the display layer is zoomed or not, the zoom coefficient is set, so that the effect that the target image moves on the display layer which is not zoomed is the same as the effect that the target image moves on the display layer which is zoomed, and the dislocation phenomenon caused when the target image moves on the display layer which is zoomed is avoided.
Further, before step S16, the image shifting method provided in this embodiment further includes, for example: judging whether the abscissa in the real-time position information of the target image is smaller than zero; when the abscissa in the real-time position information of the target image is judged to be less than zero, setting the abscissa of the target image to be zero; judging whether the abscissa of the target image is larger than the length difference between the display layer and the target image; when the abscissa of the target image is judged to be larger than the length difference value between the display layer and the target image, setting the abscissa of the target image as the length difference value; judging whether the ordinate in the real-time position information of the target image is smaller than zero; when the ordinate in the real-time position information of the target image is judged to be less than zero, setting the ordinate of the target image to be zero; judging whether the vertical coordinate of the target image is larger than the width difference value between the display layer and the target image or not; and when the vertical coordinate of the target image is judged to be larger than the width difference value between the display layer and the target image, setting the vertical coordinate of the target image as the width difference value. Whether the target image is in the limited range of the display layer or not is judged, so that the target image is guaranteed to move in the limited range of the display layer, and errors are avoided.
For better understanding of the embodiment, the image moving method provided by the embodiment of the present invention is described in detail below with reference to fig. 2. As shown in fig. 2, a large rectangular frame represents a display layer, and a small rectangular frame with diagonal lines inside represents a target image projected by a display screen body onto the display layer. Wherein the small rectangular frame on the left represents the position before the movement of the target image and the small rectangular frame on the right represents the position after the movement of the target image.
Specifically, the display layer is scaled, and the scaling multiple of the display layer is recorded as a scaling coefficient.
And selecting a target image on the display layer subjected to the zooming processing by the user by using a mouse, namely clicking a small rectangular box, wherein the target image is selected on the display layer at the moment, the point B represents a position point of the target image, and the coordinates (Xb, Yb) of the point B relative to the starting point A of the display layer are used as initial position information of the target image.
And clicking the target point in the target image by the user by using a mouse to determine the target point, namely clicking the small rectangular frame by the user to obtain a C point as the target point, and taking the coordinates (Xc, Yc) from the C point to the A point as the initial position information of the target point. It should be noted that the mouse click operations involved in the two steps may be combined into one mouse click operation, that is, after the mouse is clicked inside the small rectangular frame, the initial position information of the target image and the initial position information of the target point are obtained at the same time.
And judging whether the current display layer is zoomed or not, and if not, setting the zoom coefficient to be 1. At this time, the display layer is scaled, and the aforementioned scaling factor is used as the scaling factor multiple for the subsequent calculation.
Relative position information (X1, Y1) of the target point with respect to the target image is obtained from the initial position information (Xb, Yb) of the target image, the initial position information (Xc, Yc) of the target point, and the zoom factor multiple.
Specifically, X1 ═ Xc/multiple-Xb; y1 ═ Yc/multiple-Yb.
And dragging the target point in the display layer by using a mouse to realize the movement of the target point by the user, and obtaining the movement position information (Xc ', Yc') of the target point.
Obtaining real-time position information (Xb ', Yb') of the target image from the movement position information (Xc ', Yc'), the zoom factor multiple, and the relative position information (X1, Y1) of the target point.
Specifically, Xb '═ Xc'/multiple-X1; Yb'/multiple-Y1.
And then judging whether the real-time position information exceeds the display range of the display layer. In particular, the amount of the solvent to be used,
and judging whether the abscissa Xb ' in the real-time position information of the target image is smaller than zero, and setting Xb ' to be zero when the judgment result shows that Xb ' is smaller than zero.
And judging whether Xb ' is larger than the length difference (LeftMax-Width) between the display layer and the target image, and setting Xb ' to be (LeftMax-Width) when the Xb ' is judged to be larger than the (LeftMax-Width).
And judging whether the ordinate Yb ' in the real-time position information of the target image is smaller than zero, and setting Yb ' to be zero when the ordinate Yb ' is judged to be smaller than zero.
And judging whether Yb ' is larger than the width difference (TopMax-Height) between the display layer and the target image, and setting Yb ' as (TopMax-Height) when judging that Yb ' is larger than (TopMax-Height).
And finally, changing the position of the target image in the display layer according to the real-time position information of the target image.
In summary, in the image moving method provided in this embodiment, the relative position information of the target point with respect to the target image is obtained according to the initial position information of the target image, the initial position information of the target point, and the zoom coefficient, and the real-time position information of the target image is obtained according to the moving position information of the target point, the zoom coefficient, and the relative position information to move the target image, so that a dislocation phenomenon occurring when the target image moves on the zoomed display image layer can be avoided, a mouse dragging effect can be better achieved, and user experience can be improved.
