該樓層疑似違規已被系統折疊?隱藏此樓查看此樓

有很多magic number，修改如下

import java.awt.Font;

import java.awt.Rectangle;

import java.awt.Shape;

import java.awt.font.FontRenderContext;

import java.awt.font.GlyphVector;

import java.awt.geom.AffineTransform;

import java.awt.geom.RectangularShape;

public class FontTest

{

public static void main(String[] args)

{

Font font = new Font("黑體", Font.BOLD, 20);

AffineTransform at = new AffineTransform();

FontRenderContext frc = new FontRenderContext(at, true, true);

GlyphVector gv = font.createGlyphVector(frc, "JinCeon");

RectangularShape rs = gv.getVisualBounds();

//rs這個矩形的Y坐標為什么是負數？求解答

Shape shape = gv.getOutline((float)-rs.getX(), (float)-rs.getY());

Rectangle rect = shape.getBounds();

int width = rect.width + rect.x;

int height = rect.height;

boolean[][] view = new boolean[width][height];

for (int i = 0; i < width; i++)

{

for (int j = 0; j < height; j++)

{

if (shape.contains(i, j))

{

view[i][j] = true;

} else

{

view[i][j] = false;

}

}

}

for (int j = 0; j < height; j++)

{

for (int i = 0; i < width; i++)

{

if (view[i][j])

{

System.out.print("囧");// 替換成你喜歡的圖案

} else

{

System.out.print("?? ");// 全角半角和上面一致

}

}

System.out.println();

}

}

}
