## Graphical User Interface to Check Images for Color Constraints

### Description

A graphical user interface (GUI) to check an existing jpg/png image for (possible) color constraints. The image will be converted to protanope vision, deuteranope vision, and a desaturated version (monochromatic vision). Allows a rapid check whether the colors used in the image show some constraints with respect to color deficiency or color blindness.

### Usage

    cvd_emulator(file, overwrite = FALSE, shiny.trace = FALSE)

### Arguments

`file` | If not set, an interactive GUI will be started. If `x` is of type `character` it has to be the full path to an image of type png or jpg/jpeg. The image will be converted and stored on disc, no GUI.
`overwrite` | `logical`. Only used if `file` is provided. Allow the function to overwrite files on disc if they exist.
`shiny.trace` | `logical`. Can be set to `TRUE` for more verbose output when the GUI is started (development flag).
