Resize a bounding box object by a scale factor or buffer distance
bbox_resize(x, scale = NULL, buff = NULL)
bbox object

You can resize a bounding box by passing a value for scale
or buff
, but not both.
Use scale
to resize the bounding box with a scale factor. Values of scale
< 1 will
result in a smaller bounding box, values > 1 will result in a larger bounding box. The centroid will
remain the same. If you pass two values for scale
, they'll be used to scale the x and y
dimensions respectively
Use buff
to resize the bounding box with a fixed distance. buff
should be in a map units.
Values of buff
< 0 will result in a smaller bounding box. Values > 0 will result in a larger
bounding box. If you pass two values for buff
, they'll be used to buffer the x and y
dimensions respectively
