[Retracted] Optimization and Application of Information Visualization Design Based on Image Symbol under the Guidance of Feature Integration Theory

Algorithm 1

Fast rectangle-packing algorithm.

	For each rectangle {
	For each edge {//the order of processing edges.
	Calculate one or two candidate positions to place on ;
	For(each candidate position dt) {
	If (dt satisfies both conditions 1 and (2) {
	T = dt; goto PlaceNow;//T is the final position of.
	}
	If (dt satisfies only condition 1){
	Calculate bB + gG; //Section 4.3 describes the calculation of bB + gG.
	If (bB + gG is less than the previous candidate positions){
	T = dt;
	}
	}
	}//end of for (dt).
	}//end of for.
	PlaceNow:
	Place at T; Modify M;//the modification of the mesh.
	}//end of for.
