draw_tem: Draw template

In webmorphR: Reproducible Stimuli

Draw template

Description

Visualise a template on an image.

Usage

draw_tem(
  stimuli,
  pt.color = wm_opts("pt.color"),
  pt.alpha = 0.75,
  pt.size = NULL,
  pt.shape = c("circle", "cross", "index"),
  line.color = wm_opts("line.color"),
  line.alpha = 0.5,
  line.size = NULL,
  bg = "image"
)

Arguments

stimuli	list of stimuli
pt.color, line.color	line or point color, see color_conv()
pt.alpha, line.alpha	transparency (0-1), ignored if color is a hex value with transparency. Set alpha to 0 to omit lines or points.
pt.size, line.size	size in pixels (scales to image size if NULL)
pt.shape	the shape of the points ("circle", "cross", "index")
bg	background color ("image" uses the original image)

Details

Visualising the index of each point isn't great yet and will overlay

Value

list of stimuli with template images

Examples

# get an image with 2 different templates
stimuli <- demo_tems("frl|fpp106")

# default template
draw_tem(stimuli)


# custom template
draw_tem(stimuli, 
         pt.shape = "cross",
         pt.color = "red", 
         pt.alpha = 1,
         pt.size = 15,
         line.color = rgb(0, 0, 0),
         line.alpha = 0.5,
         line.size = 5)

# indexed template
draw_tem(stimuli, 
         pt.shape = "index",
         pt.size = 15, 
         pt.alpha = 1,
         line.alpha = 0)
