\arguments{
\item{object}{a VoltRon object}

\item{features}{a set of features to be visualized, either from \link{vrFeatures} of raw or normalized data or columns of the \link{Metadata}.}

\item{combine.features}{whether to combine all features in one plot}

\item{group.by}{a column of metadata from \link{Metadata} used as grouping label for the spatial entities}

\item{plot.segments}{plot segments from \link{vrSegments} instead of points}

\item{n.tile}{should points be aggregated into tiles before visualization (see \link{geom_tile}). Applicable only for cells and molecules}

\item{norm}{if TRUE, the normalized data is used}

\item{log}{if TRUE, data features (excluding metadata features) will be log transformed}

\item{assay}{assay name (exp: Assay1) or assay class (exp: Visium, Xenium), see \link{SampleMetadata}. 
if NULL, the default assay will be used, see \link{vrMainAssay}.}

\item{graph.name}{if not NULL, the spatial graph is with name \code{graph.name} is visualized as well, see \link{vrGraphNames}}

\item{ncol}{column wise number of plots, for \link{ggarrange}}

\item{nrow}{row wise number of plots, for \link{ggarrange}}

\item{font.size}{font size}

\item{pt.size}{point size}

\item{cell.shape}{the shape of the points representing cells, see \link{geom_point}}

\item{title.size}{title size of legend and plot}

\item{alpha}{alpha level of colors of visualized points and segments}

\item{keep.scale}{whether unify all scales for all features or not}

\item{label}{if TRUE, labels of ROIs will be visualized too}

\item{spatial}{the name of the main spatial system}

\item{channel}{the name of the channel associated with the image}

\item{background.color}{the color of plot background if a channel is not specified, or the spatial coord system doesnt have an image.}

\item{background}{(DEPRECATED) the background of the plot. Either an image name, see \link{vrImageNames} or a vector of length two with image name 
and a channel name, see \link{vrImageChannelNames}. Type "black" or "white" for black or white backgrounds. if NULL, the main image (\link{vrMainSpatial}) 
and main channel (\link{vrMainChannel}) will be in the background. Otherwise the background will be grey.}

\item{reg}{TRUE if registered coordinates of the main image (\link{vrMainSpatial}) is requested}

\item{crop}{whether to crop an image of a spot assay to the extend of spots}

\item{scale.image}{if TRUE, background image will be scaled down to a low resolution (width: 1000px)}

\item{common.legend}{whether to use a common legend for all plots, see \link{ggarrange}}

\item{legend.loc}{the location of the legend, default is "right"}

\item{collapse.plots}{whether to combine all ggplots}
