Filter: offset an element a specified amount

Source: R/filters.R

The offset filter applies an offset in the x and y directions to an existing element. The offset is handled by setting values for dx and dy.

filter_offset(dx = NULL, dy = NULL, what = "source")

Arguments

dx, dy

The offset of the element position compared to its initial position.
what

What exactly should be offset? By default, it is the "source" image.

Examples

# Add a circle element to an
# SVG drawing and offset it
# by 10px to the right
SVG(width = 150, height = 150) %>%
  svg_filter(
    id = "offset_right",
    filters = list(
      filter_offset(dx = 50, dy = 0)
    )
  ) %>%
  svg_circle(
    x = 30, y = 30,
    diameter = 40,
    attrs = svg_attrs_pres(
      fill = "red",
      filter = "offset_right"
    )
  )
