java实现图像转码为字符画的方法

java实现图像转码为字符画的方法

本文实例为大家分享了java实现图像转码为字符画的具体代码，供大家参考，具体内容如下

public class ImageProcesser {

private static final char[] charset1 = {'M','8','V','|',':','.',' '}; //默认字符素材集

private char[] charset; //字符画素材集

bZgcWuYprivate String imgString = ""; //储存转化后的字符串

//使用指定字符集构造

public ImageProcesser(char[] charset){

this.charset = charset;

}

//使用默认字符集构造

public ImageProcesser(){

this.charset = charset1;

}

public String getImgString(){

return imgString;

}

/*将图形文件转化为字符画字符串*/

public ImageProcesser toBitmapConvert(String imagepath){

return toBitmapConvert(new File(imagepath));

}

public ImageProcesser toBitmapConvert(File imageFile){

StringBuffer sb = new StringBuffer();

if(!imageFile.exists()){ //当读取的文件不存在时，结束程序

System.out.println("File is not exists!");

System.exit(1);

}

Color color;

try{

BufferedImage buff = ImageIO.read(imageFile); //将图片文件装载如BufferedImage流

buff = compressImage(buff);

int bitmapH = buff.getHeight();

int bitmapW = buff.getWidth();

//逐行扫描图像的像素点，读取RGB值，取其平均值，并从charset中获取相应的字符素材，并装载到sb中

for(int y=0; y

for(int x=0; x

int rgb = buff.getRGB(x,y);

color = new Color(rgb);

int cvalue = (color.getRed()+color.getGreen()+color.getBlue()) / 3;

sb.append(charset[(int)((cvalue * charset.length - 1)/255)]+" ");

}

sb.append("\r\n");

}

}catch(IOException ex){

ex.printStackTrace();

}

return this;

}
