Replying to an old thread ... but drops module does not work with lmtx because \pxdimen is not defined.

The drops module uses the primitive \pdfpxdimen in a couple of places, but that is no longer defined in the current beta. What is the equivalent command now?

Examples of usage:

\pdfpxdimen1in\relax\divide\pdfpxdimen\numexpr\dropsparameter\c! resolution\relax % set actual pixel dimension

just \pxdimen (as it's not related to pdf)

What will be the equivalent of \pxdimen in LMTX?

Just realized that this is a bug in t-drops: Line 143 of t-dropx.mkiv says \doifundefined{pdfvariable} {\let\pxdimen\pdfpxdimen} % \pxdimen in luatex 0.85 Commenting that out fixes the bug. Aditya

I have fixed that incompatibility some weeks ago and also posted the new version on this list. Just look at the source for the details (changes are minimal).
