Subject: "Too many raster images" in devPS.c
Hi,
I am finding the recently added [1] functionality of embedding raster
images into plots on R devices very useful! Thanks to Paul Murrell and
others for providing that. I noted that in
https://svn.r-project.org/R/trunk/src/library/grDevices/src/devPS.c
a macro is defined: #define MAX_RASTERS 64, and consequently, I get
Error in grid.Call.graphics("L_raster", x$raster, x$x, x$y, x$width,
x$height, :
Too many raster images
even for relatively innocent graphics, such as extensions of [2] (which
I made with Bioconductor's "splots" package). Besides that, I imagine
that raster images could be useful as 'glyphs' in various types of plots.
Besides the not so helpful option of patching that macro in my private
copy of R, is there an intention to extend this functionality to
accommodate for larger plots more generally?

Thank you and best wishes,
