Adjust color, brightness or contrast of the image

## S3 method for class 'image'
edit(image = NULL, file.name = NULL, grey.mode = NULL,
  brightness = NULL, contrast = NULL, red = NULL, green = NULL,
  blue = NULL)

`image`	An array of numbers between 0 and 1
`file.name`	A character (location of the image)
`grey.mode`	A character
`brightness`	A number
`contrast`	A character
`red`	A character
`green`	A character
`blue`	A character

By using an x-y-3(rgb)-representation of an image, you can change the color, brightness or contrast of that image. For adjusting brightness or contrast use a number between -1 and 1 as parameter. To get more intense colors use a number between 0 and 1 for each color parameter. By entering grey.mode = TRUE one will get a normal grey image. Other options for grey.mode are "luminosity.grey", red.grey", "green.grey" and "blue.grey".
