border_size = NULL,
border_colour = "black",
bg_fill = NULL,
just = "center"
)
crop_square(
images,
to = NULL,
border_size = NULL,
border_colour = "black",

)
crop_hex(
images,
to = NULL,
border_size = NULL,
border_colour = "black",
bg_fill = NULL,
just = "center"
)
crop_heart(
images,
to = NULL,
border_size = NULL,
border_colour = "black",
bg_fill = NULL,
just = "center"
)
crop_parallelogram(
images,
to = NULL,
border_size = NULL,
border_colour = "black",
bg_fill = NULL,
just = "center"
)
circle_crop(
images,
to = NULL,
border_size = NULL,
border_colour = "black",
bg_fill = NULL,
just = "center"
)
hex_crop(
images,
to = NULL,
border_size = NULL,

)
Arguments
images |
Vector of image paths, either local or urls. If urls the images will be downloaded first. |
to |
Path to new location |
border_size |
Border size in pixels. |
border_colour |
Border colour. |
bg_fill |
Background fill. Allows a different colour for the background and a different colour for the border. |

Examples
library(cropcircles)
library(magick)
img_path <- file.path(system.file(package = "cropcircles"), "images", "walter-jesse.png")
img_cropped <- crop_circle(img_path, border_size = 6)
image_read(img_cropped)
# justification example
# center (default)
image_read(crop_circle(img_path, border_size = 6))
# left
image_read(crop_circle(img_path, border_size = 6, just = "left"))
# right
image_read(crop_circle(img_path, border_size = 6, just = "right"))
