take.screenshot R Documentation
Take screenshot of rgl scene, with fallback for systems without X11.
Description
Takes a screenshot of the current rgl scene. On systems with working X11/OpenGL,
uses the standard rgl.snapshot() method. On systems without X11 (e.g., recent macOS versions
where XQuartz is broken), falls back to exporting as PDF via rgl.postscript() and converting
to PNG using ImageMagick.
Usage
take.screenshot(output_image, silent = TRUE)
Arguments
output_image
character string, path to the output PNG file.
silent
logical, whether to suppress messages. Default TRUE.
Value
invisible NULL, called for side effect of writing the image file.
