Annotation: High-performance rectangular tiling (ggtern version)
This is a special version of geom_raster optimised for static
annotations that are the same in every panel. These annotations will not
affect scales (i.e. the x and y axes will not grow to cover the range
of the raster, and the raster must already have its own colours).
annotation_raster_tern(raster, xmin = 0, xmax = 1, ymin = 0, ymax = 1, interpolate = FALSE)
raster |
raster object to display |
xmin, xmax |
x location (in npc coordinates) giving horizontal location of raster |
ymin, ymax |
y location (in npc coordinates) giving vertical location of raster |
interpolate |

Most useful for adding bitmap images.
