Flip the surface matrix of an x3p file along the x axis.
Examples
logo <- x3p_read(system.file("csafe-logo.x3p", package="x3ptools"))
dim(logo$surface.matrix)
#> [1] 741 419
if (FALSE) { # \dontrun{
x3p_image(logo)
} # }
# flip the y-axis for the old ISO standard:
logoflip <- x3p_flip_x(logo)
dim(logoflip$surface.matrix)
#> [1] 741 419
if (FALSE) { # \dontrun{
x3p_image(logoflip)
} # }
