Generate images with ImageMagick without saving to file but still display them on website

Question

This is my ImageMagick code which works fine on my webserver by creating new image with the file name \'coloured_font.png\' in a default directory ...

Answer 1

You will have to create a temporary file

Steps

1. Create a temporary file, temp_image.jpg by running imagemagick command in shell

2. Send this as http response

   $file = 'pathto/temp_image.jpg';
   $type = 'image/jpeg';           // set appropriate type    
   header('Content-Type:'.$type);  // set content type
   header('Content-Length: ' . filesize($file));
   readfile($file);
   

3. Delete temp_image.jpg

Suppose this is in getImage.php, it can be given as the source of an image tag
