Question

I have this code where I am trying to read an image from Url:

   public class question_insert {
public static String latex(String tex) throws IOException {

    String urltext = "http://chart.apis.google.com/chart?cht=tx&chl="+tex;

    URL url = new URL(urltext);
    BufferedReader in = new BufferedReader(new InputStreamReader(url
            .openStream()));
    String inputLine;

    while ((inputLine = in.readLine()) != null) {
        // Process each line.
        System.out.println(inputLine.toString());

    }
    in.close();

    return inputLine;}

But what I am getting is unreadable code. The url gives only one image try this:

http://chart.apis.google.com/chart?cht=tx&chl=2+2%20\frac{3}{4}

What should I do to embed the image into Html?

Answer 1

Well, I don’t know if that is what you want because it seems that nobody does. But if you want to get this output

<img style="-webkit-user-select: none" 
src="http://chart.apis.google.com/chart?cht=tx&chl=2+2%20\frac{3}{4}" />

you will have to use this code

public static String latex(String tex) {
    String url = "http://chart.apis.google.com/chart?cht=tx&chl=" + tex;
    return "<img style=\"-webkit-user-select: none\" src=\"" + url + "\"/>";
}

Also you might have to escape some characters like \ in the tex parameter.
