The process of converting the theoretical coordinates of various types of topological nodes into page coordinates in an actual display page is as follows:
step 1, assuming that the distance between two adjacent topological nodes along the x-axis direction is 0, calculating the width of a coordinate system: nodeW (calcW +1);
step 2, assuming that the distance between two adjacent topological nodes along the y-axis direction is 0, calculating a coordinate system to be high: nodeH (calcH +1);
Step 3, calculating the width of a preset display page: nodeW (calcW +1) + xGap (calcW +2);
step 4, calculating the height of a preset display page: nodeH (calcH +1) + yGap (calcH +2);
and 5, comparing the sizes of the preset display page and the actual display page, and taking a larger value.
Step 6, determining a first target pitch xMGap and a second target pitch yMGap.
Step 7, sequentially converting theoretical coordinates (calcX, calcY) of the topological nodes into page coordinates (pageX, pageY) in the actual display page:
pageX＝(calcX–calcLeft)*nodeW+(calcX–calcLeft+1)*xMGap
pageY＝(calcY-calcTop)*nodeH+(calcY–calcTop+1)*yMGap。
According to the steps, the page coordinates of the topological nodes of each type in the actual display page can be calculated. And displaying the master and slave cluster topological graphs in an actual display page.
