Change default DPI with code snippet?

    Hello – We have been editing the ‘dompdf_config.inc.php’ file on line 241: def(“DOMPDF_DPI”, 96); changing it to 300 for better image quality.

    Is there a function we can add to the plugin code snippets to replace this code by default so it is more compatible with updates?

    Thanks in advance!

    Hi! the def() method is there precisely to let you override this (in functions.php or Code Snippets).

    
define("DOMPDF_DPI", 72);

    However, changing this will not do anything for the image quality, it will simply make dimensionless images smaller in size (mm/inches). DOMPDF doesn’t do any resampling but just uses the DPI to calculate the size for images if it only knows pixels. If you enter a size in mm/inches in your css, you can simply increase the DPI by making the picture larger (more pixels).

    Hope that helps!
