plot.adimpro: I/O functions

Description

Visualize image data.

Usage

## S3 method for class 'adimpro':
plot(x, new=FALSE, gammatype = NULL, cspace = NULL,
                 whitep = NULL, temp = NULL, black = 0, exposure = 1,...)

Arguments

image object of class "adimpro"

new

should new X11() be opened? default FALSE

gammatype

character, determines the type of gamma correction within the image. "ITU" stands for ITU-R BT.709-3 as e.g. used by dcraw. Alternatives recognized within the package are "None", "sRGB" and "CIE" (CIE L*). NULL keeps th

cspace

defines the output color space, default "sRGB" (sRGB D65), alternatives are "Adobe" (Adobe 1998 D65), "wGamut" (Wide Gamut D65), "kodak" (Kodak ProPhoto D65) "xyz", "yuv", "yiq" and "hsi". NULL keeps the actual setting.

whitep

White point in xyY space. Can be given as one of (character) c("A","B","C","E","D50","D55","D65","D75","F2","F7","F11") or as a two element numeric vector of chromatic xy coordinates. "D65" correspo

temp

Color temperature. Can be used to specify chromatic xy coordinates of the whitepoint. Only used if is.null(whitep).

black

Adjustment for black color. Color values with luminance

exposure

Multiplicative factor for all color channels (in xyz or rgb spaces). Applied in linear color space, i.e. if the image is gamma corrected the gamma correction is reversed first.

...

not used

Value

nothing is returned.

Details

This functions shows information on the image. This includes histograms of color values in each channel of the specified (x$type) color space, a thumbnail (in "sRGB" with gamma correction gammatype if specified and gammatype="ITU" elsewhere), some information on the image and, if x was produced by awsimage, an image illustrating the local adaptation.
