Question

in my app I need to get character from extended ASCII table that is shown on the image. But when I cast decimal values into char, I get different characters. What is the real value of these characters in JAVA. I dont write the character on console or in a file, just into the image.

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;
}

Thank you for your help, and sorry for my poor English 🙂

Answer 1

My solution for this problem is that I manualy created a char array with those characters I needed
