Perform deferred/lazy operations — doDeferred • GiottoClass

Force deferred/lazy operations.

Usage

# S4 method for class 'giottoAffineImage'
doDeferred(x, size = 5e+05, filename = NULL, ...)

Arguments

x: object to force deferred operations in
size: numeric. Minimum number of image pixels to render when evaluating
filename: character. Full filepath to write the rendered image to. If NULL, a file in tempdir() will be generated.
...: additional args to pass

Examples

gimg <- GiottoData::loadSubObjectMini("giottoLargeImage")
affimg <- spin(gimg, 45) # lazily performs affine

# force the affine operation and render the output with at least 5e5 px
gimg2 <- doDeferred(affimg, size = 5e5)
# **This is mainly intended for visualization.**
# This process saves with image depth of 8.
# Spatially transformed raster values are not preferred for analysis
