Embodiment
The method of simulating various screen resolutions of the present invention and device thereof, it can create different virtual screens according to the different resolution sizes that is provided with, length and width to the track of mouse drag are changed, and in virtual screen, show track after this conversion, with the effect that allows under the user experience different screen resolutions, user's computer hardware of need not upgrading gets final product simulating various screen resolutions, saved upgrade cost and saved update time easy to use, the scope of adjustable resolution is bigger in addition, meets consumers' demand.
Below in conjunction with accompanying drawing specific embodiments of the invention are done a detailed elaboration.
As Fig. 1, the method for simulating various screen resolutions of the present invention comprises step:
S101, create virtual screen according to the resolution sizes that is provided with; The resolution of this setting can be that the user is provided with as required, also can just set in advance, and its resolution that sets in advance is general identical with the resolution of current computer screen.Such as the resolution sizes that is provided with is 1024 * 768, and then the length of virtual screen is 1024 pixels, and width is 768 pixels; Certainly the length of the virtual screen of creating and wide also can be in direct ratio with resolution sizes;
Horizontal ordinate ratio, the ordinate ratio of S102, the described virtual screen of calculating and current computer screen; Such as, the resolution sizes of virtual screen is 1024 * 768, and the resolution of current computer screen is 1280 * 780, and then the horizontal ordinate ratio is 1024/1280, and the ordinate ratio is 768/780;
S103, in described current computer screen, draw the track of mouse drag; The track of this mouse drag can be a straight line.Also can directly from computing machine, load pre-rendered good track in addition;
S104, obtain the length and the width of the track of described mouse drag, the length and the width of described track are changed, and in described virtual screen, show track after the conversion according to described horizontal ordinate ratio and ordinate ratio.
The length of the track of mouse drag and width can calculate according to the starting point of mouse drag and the horizontal ordinate distance between the terminal point, can certainly be length and the width that pre-sets, the length of the track of this mouse drag and the scope of width be within length that pre-sets and width range.When conversion, the length of the track of the mouse drag obtained be multiply by the horizontal ordinate ratio, the width of the mouse drag track that obtains be multiply by the ordinate ratio, can finish conversion, and then the track after the demonstration conversion, so just can let user experiencing the effect of track under different resolution that mouse drag is drawn, and the computer hardware of need not upgrading, it is also more convenient to provide cost savings use simultaneously.
In a preferred embodiment, the method of simulating various screen resolutions of the present invention can also comprise step: calculate described virtual screen with respect to the horizontal ordinate side-play amount of described current computer screen, ordinate side-play amount (side-play amount can for just also can be for negative), and the starting point and the terminal point coordinate of described mouse drag are changed, and show coordinate after this conversion according to described horizontal ordinate side-play amount and ordinate side-play amount.During concrete enforcement, horizontal ordinate side-play amount OffsetX=(current computer screen length-virtual screen length)/2, ordinate side-play amount OffsetY=(current computer screen width-virtual screen width)/2.When the starting point of mouse drag and terminal point coordinate are changed, the horizontal ordinate of starting point and terminal point can be added the horizontal ordinate side-play amount respectively, the ordinate of starting point and terminal point is added the ordinate side-play amount respectively, to finish conversion to the coordinate of starting point and terminal point, and the coordinate after will changing is shown to the user and checks, so that the user carries out editing operation to it.
Less than current computer screen resolution 1024 * 768, Fig. 5 virtual screen resolution 1280 * 1024 is greater than current computer screen resolution 1024 * 768 as Fig. 4 virtual screen resolution 800 * 600; The upper left corner starting point of current computer screen is rleft (0,0), the upper left corner starting point of virtual screen is vleft (0,0), virtual screen is that OffsetX, ordinate side-play amount are OffsetY with respect to the horizontal ordinate side-play amount of current computer screen, the void screen coordinate of rectangular object in virtual screen is shown to the user and checks, void will be shielded coordinate and add corresponding horizontal ordinate side-play amount respectively when being shown to computer Recognition.
In a preferred embodiment, the method for simulating various screen resolutions of the present invention can also comprise step: the coordinate after coordinate when writing down the track of drawing in the described current computer screen of click and mouse move; The distance that coordinate Calculation mouse after moving according to the coordinate of this click and mouse moves on horizontal longitudinal direction; According to described horizontal ordinate ratio and ordinate ratio the distance that mouse moves on horizontal longitudinal direction is changed; Starting point and terminal point coordinate according to the mouse drag of the distance on the horizontal longitudinal direction after the described conversion after to described conversion are changed once more, and show this coordinate after changing once more.So just the starting point and the terminal point coordinate of the mouse drag after moving can be shown, check editor for the user.
Introduce down the method that the present invention simulates various resolution in detail below in conjunction with a specific embodiment.
At first create a virtual screen according to the resolution 800 * 600 that is provided with; The length of virtual screen is 800 pixels, and width is 600 pixels; The current computer screen resolution is 1024 * 768, and the length of current computer screen is 1024 pixels, and width is 768 pixels;
The upper left corner of getting the current computer screen is original coordinates starting point rleft (0,0);
Calculate horizontal ordinate side-play amount OffsetX=(the 1024-800)/2=112 of virtual screen, ordinate side-play amount OffsetY=(768-600)/2=84 with respect to the current computer screen;
