paintObjects {EBImage} | R Documentation

## Marking detected objects in reference images

### Description

This function allows to mark objects detected with `getObjects` or `watershed` in colour for preview.

### Usage

         paintObjects(x, tgt, opac=c(0.4, 0.05, 0.4), col=c("#FFC72C","#5BABF6","#FF372C"), ...)

### Arguments

`x`
  An object of `Image-class` in the `Grayscale` mode with integer-absed object encoding, as returned by `watershed`.
`tgt`
  A reference grayscale image to calculate object intensity. Should be `TrueColor` to produce coloured output.
`opac`
  A numeric vector of opacity values for foreground (object boundary), object background and edges of object contacts. At least 3 values in the above sequence must be supplied. Opacity range is `[0,1]` with 0 being fully transparent.
`col`
  A character vector of full colours (before opacity applied), colour names supported, to draw object boundaries, object background and edges of object contacts. At least 3 values must be supplied. Default color scheme is yellow for edges, blue for background and red for object contacts and object on image edges.
`...`
  Reserved for future use.

### Value

A copy of `tgt` in the same colour mode with objects marked on top of the image. `features` of `x` are not transfered – this result is for visualization only.
