在我的应用程序中,我需要获取扩展ASCII表中显示的字符。但是,当我将十进制值转换为字符时,我得到不同的字符。这些字符在JAVA中的实际值是什么?我没有在控制台或文件中写入字符,只是写入图像中。
private void generateAsciiMatrix()
{
//32 - 255 are visible characters in ascii table
for(int i = 32; i < 256; i++)
{
this.generateAsciiMatrix((char)i);
}
}
private void generateAsciiMatrix(char letter)
{
EBufferedImage character = new EBufferedImage(
ImageClass.charToImage(letter, width, height));
//...some code
}
public static BufferedImage charToImage(char c, int width, int height)
{
BufferedImage off_Image = new BufferedImage(width, height,
BufferedImage.TYPE_BYTE_GRAY);
Graphics2D g2 = off_Image.createGraphics();
g2.setColor(Color.black);
g2.setBackground(Color.WHITE);
g2.clearRect(0, 0, width, height);
g2.setFont(new Font("Monospaced", Font.PLAIN, 12));
g2.drawString(Character.toString(c), 0, height);
saveImage(off_Image, "code" + (int)c);
return off_Image;
}
感谢您的帮助,对于我的英语不好,非常抱歉 :-)
