Description#

Updates the spatial positioning and sizing of a giotto image or largeImage attached to a giotto object.

Usage#

updateGiottoImage(
  gobject = NULL,
  image_name = NULL,
  largeImage_name = NULL,
  xmax_adj = 0,
  xmin_adj = 0,
  ymax_adj = 0,
  ymin_adj = 0,
  x_shift = 0,
  y_shift = 0,
  scale_factor = NULL,
  scale_x = 1,
  scale_y = 1,
  order = c("first_adj", "first_scale"),
  xmax_set = NULL,
  xmin_set = NULL,
  ymax_set = NULL,
  ymin_set = NULL,
  return_gobject = TRUE,
  verbose = TRUE
)

Arguments#

Argument

Description

gobject

gobject containing desired image object

image_name

name of giotto image object

largeImage_name

name of giotto largeImage object

xmax_adj, x min_adj, ymax_adj, ymin_adj

adjust image boundaries by increasing maximum and decreasing minimum bounds respectively of xy bounds

x_shift, y_shift

shift entire image along xy axes

scale_factor

set scale_x and scale_y params at the same time

scale_x, scale_y

independently scale x or y axis image mapping from coordinate origin

order

order of operations between fine adjustments (adjustment and shift parameters) and scaling

xmin_set, x max_set, ymin_set, ymax_set

directly set xy image boundaries. Overrides minmax values as spatial anchor.

return_gobject

return a giotto object if TRUE , a giotto image object if FALSE

verbose

be verbose

Details#

This function works for all image objects associated with Giotto.

Value#

a giotto object or an updated giotto image object if return_gobject = F
