img_dpi – Specify size conversion for images using pixels


void img_dpi

Specify how to convert image sizes specified in px units (pixels). As a print medium, PDF documents do not have any inherent size for pixels. Width and height values of images set in pixels need to be converted to a real length. The dots-per-inch (dpi) affects the conversion from pixels for images; other objects using pixels as a length, are set by a separate variable $dpi




  • INTEGER : set conversion for pixel - dots per inch
