如何在圖像上附加文字時添加高度元素

Question

我在尋找是否可以在給定Example中添加高度元素。

，這樣我可以指定

public void drawString(Graphics g, String s, int x, int y, int width,int height) 

現在，如果我的文字超過其高度下次上的文字重疊。

我沒有測試，但可能會幫助你解決問題..

public void drawString(Graphics g, String s, int x, int y, int width, int height) { 
    // FontMetrics gives us information about the width, 
    // height, etc. of the current Graphics object's Font. 
    FontMetrics fm = g.getFontMetrics(); 

    int lineHeight = fm.getHeight(); 

    int curX = x; 
    int curY = y; 
    int totalHeight = 0; 

    String[] words = s.split(" "); 

    String word = ""; 
    // end of words array wasn't reached and still some space left 
    for(int i = 0; i < words.length && totalHeight <= height; i++) { 

     // Find out thw width of the word. 
     int wordWidth = fm.stringWidth(word + " "); 

     // If text exceeds the width, then move to next line. 
     if (curX + wordWidth >= x + width) { 
      curY += lineHeight; 
      totalHeight += lineHeight; 
      curX = x; 
     } 

     g.drawString(word, curX, curY); 

     // Move over to the right for next word. 
     curX += wordWidth; 
    } 
}
