HP 15C printable overlay template

I've attached the PDF files for the Silhouette cutters. I think that you have to have the "business" license for the Silhouette cutters to be able to import PDF. I might be able to turn these into some other format, but I haven't tried.

I've attached the voyager-overlay-cut.pdf and dm1xl-overlay-cut.pdf used for the Silhouette. You could also print those and cut them with a knife, but it would obviously be a huge amount of work.

I've also attached as examples the voyager-overlay-print.pdf and dm1xl-overlay-print.pdf, which I used to print shifted legends and registration marks with the inkjet printer before cutting. These are overlays for my WIP 16C with trig and exponents microcode. For testing the overlay was printed in black, but the intention is to later print them in color, for a black background and gold and blue legends.

These were generated by a C++ program. At the moment the program is broken due to API changes to the podofo library it uses, so it doesn't make sense to publish the source code just yet. Currently the legends to be printed are hard-coded in the C++ source file, but I'll probably change that to reading legends from an XML file.

I showed some overlays made this way at HHC 2023.

Excellent, thank you very much. I will have to go the ruler+blade route to cut the holes for the keys. I didn't even imagine there was such a cutter machine.. every day you learn something. But it would be overkill to get one just for the calculator overlays. I'll hand-cut them out of some durable material, something translucent so the underlying markers show through.

If you can share the dimensions from your code, I can write a Cairo C program to render PDFs which should have better API stability.
