Description

The "*tools/htmlimage" utility allows you to generate an image file (.png, .jpg, .bmp) based on a URL, whether it is a website reference (starts with http:// or https://) or a reference to an HTML file (starts with file:///).

Important Note:

To generate an image based on a URL, certain third-party applications are required:

   •  On Windows servers, the Chrome browser is recommended for generating images; however, the Firefox browser (v57 and later) can also be used to generate images.

   •  On Linux servers, the Firefox browser (v57 and later) will generate .png images. To generate .jpg and .bmp images, the ImageMagick command line tool must also be installed.
