And judging the up-down, left-right and moving marks of each small square, and judging whether the grids are combined according to the marks. If there is a merge, then merging neighboring tiles and deleting the merge grid middle row and column dividing line. In addition, the grid may move over the dividing line, so that it is required to judge that the grid has moved by several square distances according to the scaling factor of the actual grid size and the standard grid size.
Formula for calculating display of performance window
New window size coordinates X1, Y1, wd, ht values are calculated, scaled scale sl=m1/m 2. The size of the presentation window needs to be displayed in a layout according to the actual resolution of the screen. When the display of the presentation window is performed, the display is required to be performed according to different screen resolutions, and due to the fact that the window size is required to be adjusted to be the size when the template is previewed and the program is edited, the size is required to be adjusted to be the size when the preview is edited, and then the zoom display is performed on the preview editing window according to the actual resolution. Scaling is carried out in the qualified window according to the resolution, so that the playing of the broadcasting program can be ensured to be played and displayed according to the same proportion as the resolution of the actual screen. And x/Lw and y/Lh are proportional values of the layout window and the display window, and the actual window position size is obtained by multiplying the actual resolution of the screen by a proportional coefficient according to the proportional values. Namely, the presentation management module draws a play window according to the resolution, window position and size of the presentation template, and comprises the following steps:
according to the formula
X1= x / Lw * RW
Y1= y / Lh * RH
Wd= w / Lw * RW
Ht=h / Lh * RH
The above formula mainly calculates the window layout size (x 1, y1 window coordinates, wd, ht window size) in the actual display of the terminal. For example x1=x/lw×rw, the X coordinate value of the window is calculated. The actual window coordinates are obtained by arranging a plurality of window layouts horizontally or vertically on the terminal output with respect to the actual resolution of the screen of the terminal device, and the sizes of the windows are drawn and displayed according to the size of the template of the management client. In the process of making the template, the management client performs scaling according to the resolution of the terminal to generate a proper drawing area, the user edits the window in the area, and finally the size of each window of the template is calculated by calling the formula.
Lw, lh are the actual resolution widths of the terminals. x/Lw is a scaling factor relative to the screen resolution, RW and RH are the sizes of the actual UI interfaces, and in the actual layout, a width or a height is selected as a reference, and a height is generally selected as a reference, so that the layout display screen width is calculated to be rw=lw/lh×pro_h. By selecting the reference object, in actual display, the correct display of the multi-window layout can be self-adapted, and the problem of window stretching deformation is avoided.
Broadcast program ordering algorithm
And controlling the outer layer cycle execution times by T, controlling the inner layer cycle execution times by S, judging the sizes of T1 and T2, and if the conditions are met, exchanging. The broadcasting programs need to be sequentially broadcast according to the broadcasting time, so that the broadcasting time of all broadcasting programs needs to be loaded, then the broadcasting time is converted into microseconds, and the small and large orders are performed according to the bubbling ordering method. And calculating the current time, comparing the current time with the ordered time, and removing all the playing time smaller than the current system time, wherein the rest time is the time to be played. The broadcasting program is played according to the broadcasting time sequence, the broadcasting time is up, the broadcasting program which is being played is stopped, and the next broadcasting program is played.
Grid merging algorithm
And controlling the outer layer circulation execution times, and judging whether the coordinate value after merging is equal to the coordinate value of the grid row and column during dragging. And judging whether the adjacent grids are merged or not according to the up-down, left-right and moving marks of the grids. If two or more grids are to be combined, the common dividing line is required to be cleared, the dividing line of the outermost layer is reserved, and row and column information and a combination mark of adjacent grids are recorded. Dragging the grid dividing line leftwards or rightwards, and recording the dragging distance and the moving mark. And calculating the proportional coefficient of the moving distance and the standard grid size, and clearing the dividing line according to the proportional coefficient.
Grid splitting algorithm
And judging whether coordinate values of adjacent grid areas are coincident or not. And judging whether the grids are merged or not according to the grid initial coordinate value, the size and the movement mark. If there is a merge, calculating a coefficient of proportionality of the merge grid size to the standard grid size according to the standard grid size, if the coefficient is greater than 1.0, the merge grid spans more than one standard grid; less than 1.0, one standard grid is moved. The merging grids are partitioned according to the grid size, and the moving partition lines are cleared. When the combined grids are split, the moving mark is automatically judged, if the moving mark is moved, the moving dividing line is cleared according to the moving distance, and the initial dividing line of the grids is restored.
Grid addition and insertion row algorithm
And (3) controlling the cycle execution times of the two layers of cycles, recording an old value by using an intermediate variable, and judging whether the position of the old value is changed. And judging the specific coordinate value of the mouse click position in the grid, and judging that the inserted position is in a plurality of rows and columns according to whether the grid coordinate value contains the coordinate of the mouse click. According to the standard grid size, if a column is inserted, the grid width is divided equally; if a row is inserted, the grid height is divided equally and a dividing line is inserted at a suitable position. When adding and inserting lines in the combined square, splitting the combined square, calculating the adding and inserting positions, and finally adding line dividing lines.
Specifically, the inter cut management: and inserting emergency resources into the running display terminal. The specific flow is as follows
