Problem with images created with terra::colorize() in leaflet::addRasterImage

[aloboa]

Is there perhaps something to be attempted from the terra side to at least circumvent the problem
described at the end of rstudio/leaflet#900 ?

Can you provide a reproducible example?

[aloboa]

library(RStoolbox) #for the lsat image
library(terra)
library(leaflet)

class(lsat)
r <- terra::subset(lsat,c(7,5,4))
r <- stretch(r, minq=0.00, maxq=1)
RGB(r) <- 1:3
r[r==0] <- NA
a <- colorize(r,"col")
plot(a)

leaflet() |>
addRasterImage(a, group="a")

Actually
plet(a)

is also uggly

plet(a) and plet(r) look much better in the dev version of terra (probably because I improved the color-table created by colorize). So I think this has been solved.

plet(a)

I confirm it works fine with terra 1.8.3
