NAME

blind-single-colour - Generate a single-colour video

SYNOPSIS

blind-single-colour [-f frames | -f 'inf'] -w width -h height (X Y Z | Y) [alpha]

DESCRIPTION

blind-single-colour prints a single-colour video to stdout. The video have the colour specified by the arguments X, Y, and Z, and the selected alpha value. The colour is specified in CIE XYZ. If X and Z are not specified, the colour will be CIE Standard Illuminant D65-grey with the luminosity Y. If alpha is not specified, 1, which means fully opaque, will be used.

OPTIONS

-f frames

The number of frames in the video. If frames is 'inf', the number of frames will be specified as 0 in the output's head (works fine with most blind tools) but the video will be printed to stdout until there are no processes with an open read end to this process's stdout.

-w width

The width of the video, in pixels.

-h height

The height of the video, in pixels.

NOTES

blind-single-colour may be changed in the future to use some other colour model, therefore, it is recommended to also use blind-colour-ciexyz(1) if you are specifying the colour in CIE XYZ. If however your values are colour space-agnostic, you should not.
