How to make an image responsive in Java using rethumb?
The following code prints HTML with responsive images support. It's ready to use and defines three levels of resolution: 400px, 800px and original image.
Adapt and start using the following code in Java (we use Picturefill as polyfill):
public class JavaRethumbExample
{
public static void main(String [] args) throws Exception
{
String imageUrl = "http://images.rethumb.com/image_coimbra_999x999.jpg";
int smallWidth = 400; // Image width for small resolutions (less than 400px).
int largeWidth = 800; // Image width for medium resolutions (less than 800px).
int imageWidth = 999; // Image original width (used for resolutions larger than 800px).
System.out.println(
"<script src=\"https://cdnjs.cloudflare.com/ajax/libs/picturefill/2.3.1/picturefill.min.js\"></script>\n"+
"\n"+
"<img src=\"http://api.rethumb.com/v1/width/"+smallWidth+"/"+imageUrl+"\"\n"+
"\n"+
" srcset=\"http://api.rethumb.com/v1/width/"+smallWidth+"/"+imageUrl+" "+smallWidth+"w,\n"+
" http://api.rethumb.com/v1/width/"+largeWidth+"/"+imageUrl+" "+largeWidth+"w,\n"+
" "+imageUrl+" "+imageWidth+"w\"\n"+
"\n"+
" sizes=\"100vw\" />"
);
}
}
