cols |
A character vector/matrix/array, including color names or hex values for sRGB/sRGB-A space. |
single.flag |
Logical, if true, return a single TRUE/FALSE value. |
nchannels |
Integer, either three or four, determining the number of output channels. |
as.list, as.array |
Logical values, if true, return a list or array, see value section. |
... |
Ignored. |
The is.opaque function is used to test if the input contains any non-opaque colors.
The standardize.cols function converts all colors into a hex strings.
The result will be all 3 channel or 4 channel values, not a mixture of two.
The vt3.prep.cols function is a combination of the two functions above.
By default, is.opaque returns a single logical value.
If single.flag is false, it returns a logical vector/matrix/array matching the dimensions of cols.
By default, standardize.cols returns a character vector/matrix/array matching the dimensions of cols.
If as.list or as.array are true, it returns a list or array, respectively.
In lists, each element corresponds to each channel, and in arrays, the last dimension corresponds to each channel.
vt3.prep.cols returns a length two list, containing the opaque flags and the standardized colors.
