You can insert a whatsit/pdf_literal node before and after the glyph/box you want to rotate. IIRC the "cm" operator (use with q...Q) does exactly what you want. You need a bit of math, but that's not much more than school math (but I had to relearn everything as school was so long ago). To transform the page, you can probably use the AtBeginShi package (name?). Take a look at the code for the luacolor package. Patrick
