從數組中生成圖像.pgm

Question

有很多關於閱讀.pgm圖像的帖子，但是沒有或幾乎大約有生成一個來自數組。

Answer 1

好了，所以我想通了如何將二維數組轉換成PGM文件：

try{ 
    //specify the name of the output.. 
    FileWriter fstream = new FileWriter("output.pgm"); 
    //we create a new BufferedWriter 
    BufferedWriter out = new BufferedWriter(fstream); 
    //we add the header, 128 128 is the width-height and 63 is the max value-1 of ur data 
    out.write("P2\n# CREATOR: XV Version 3.10a Rev: 12/29/94\n128 128\n63\n"); 
    //2 loops to read the 2d array 
    for(int i = 0 ; i<tabDecode.length;i++) 
     for(int j = 0 ; j<tabDecode[0].length;j++) 
      //we write in the output the value in the position ij of the array 
      out.write(tabDecode[i][j]+" "); 
    //we close the bufferedwritter 
    out.close(); 
    } 
catch (Exception e){ 
    System.err.println("Error : " + e.getMessage()); 
}
