plot_lw {pliman} | R Documentation |
Plot length and width lines on objects
Description
This function plots the length and width lines given an object
computed
with analyze_objects()
. The function does not call plot.new
, so it must
be called after an image is plotted. This can be done either using, e.g.,
plot(img)
, or analyze_objects(..., plot = TRUE)
.
Usage
plot_lw(
object,
col_length = "red",
col_width = "green",
lwd_length = 2,
lwd_width = 2
)
Arguments
object |
An object computed with |
col_length |
The color of the length line. Default is |
col_width |
The color of the width line. Default is |
lwd_length |
The line width of the length line. Default is 2. |
lwd_width |
The line width of the width line. Default is 2. |
Details
This function takes an object computed with analyze_objects()
and
plots the length and width lines of each object onto an image. The length
and width lines are calculated based on the position and orientation of the
object, and are plotted using the specified colors and line widths.
Examples
img <- image_pliman("flax_leaves.jpg")
res <- analyze_objects(img, watershed = FALSE, show_contour = FALSE)
plot_lw(res)
