Updates the boundaries of a giotto largeImage
object
attached to a giotto
object if both gobject
and largeImage_name
params are given. Alternatively can directly
accept and return as largeImage
Usage
updateGiottoLargeImage(
gobject = NULL,
largeImage_name = NULL,
giottoLargeImage = 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"),
xmin_set = NULL,
xmax_set = NULL,
ymin_set = NULL,
ymax_set = NULL,
return_gobject = TRUE,
verbose = TRUE
)
Arguments
- gobject
giotto
object containing giottolargeImage
object- largeImage_name
name of giotto
largeImage
object- giottoLargeImage
largeImage
object to directly update- xmax_adj, xmin_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
andscale_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, xmax_set, ymin_set, ymax_set
directly set xy image boundaries. Overrides minmax values as spatial anchor.
- return_gobject
return a
giotto
object ifTRUE
, a giottolargeImage
object ifFALSE
- verbose
be verbose
