View source: R/cvd_image.R

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

1
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).
