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

`x`	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 the actual setting. `gammatype="histogram"` forces histogram equalization based on the corresponding greyvalue image.
`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"` corresponds to the default white point of `"sRGB"` and `"Adobe"` RGB-spaces. `NULL` keeps the actual setting.
`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 <= black will be assigned to black in RGB. Adjustment ist done in xyY space.
`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

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.
