No, you would have to extend/replace PageDrawer.java which is somewhat tricky
and your PDFs won't look good. Stencil images are usually harmless, this is
just a badly made PDF. There are many ways in PDF to exploit its algorithmic
complexity vulnerabilities.
There will have to be a better solution in the future, maybe (tricky) use the
clipping region to limit the size, or (easier) put a hard limit like already
done in TilingPaint. There the size is limited to 3000 x 3000. (can be set
higher if wanted)
