its not possible .The CSS filter property might not be supported in all PDF rendering engines.this Advanced pdf/html template renderd engine is also one of that
some PDF readers do not fully support CSS filters. Always test your templates to ensure they display correctly.
It seems you’re asking in relation to the company logo. I would suggest simply uploading a grayscale version of your company logo and using that in the template instead.
No mate.i want to load the logo from location record.depends upon the location, logo varied and that logo will be printed in black and white .
