Draw Text on an Image — drawText • Rvision

drawText draws text over an Image object. This operation is destructive: it changes irreversibly the Image object and cannot be undone.

drawText(image, text, x, y, font_face = "simplex", font_scale = 1,
  italic = FALSE, color = "red", thickness = 1, bl_orig = TRUE)

Arguments

image	An `Image` object.
text	A character string representing the text to be drawn.
x	A numeric value representing the x coordinate of the bottom left corner of the text string (or top left if `bl_orig == TRUE`).
y	A numeric value representing the y coordinate of the bottom left corner of the text string (or top left if `bl_orig == TRUE`).
font_face	A character string representing the font type of the text (default: "simplex"). See notes for a list of available font types.
font_scale	A numeric value representing the scale factor by which the font-specific base size is multiplied (default: 1).
italic	A logical specifying whether the text should italicized (default: FALSE).
color	Any kind of R color specification compatible with `col2rgb` representing the color of the line (default: "red").
thickness	A numeric value representing the thickness in pixels of the line (default: 1).
bl_orig	A logical specifying the origin of the text drawing (default: TRUE). If TRUE, the text is drawn right-side-up. If FALSE, it is drawn upside-down.

This function does not return anything. It modifies image in place.
