	1 .TH BLIND-CONE-GRADIENT 1 blind
	2 .SH NAME
	3 blind-cone-gradient - Generate a video with a cone gradient
	4 .SH SYNOPSIS
	5 .B blind-cone-gradient
	6 [-a \| -s]
	7 -w
	8 .I width
	9 -h
	10 .I height
	11 .SH DESCRIPTION
	12 .B blind-cone-gradient
	13 prints a video with a cone gradient to stdout,
	14 parameters for each from is read from each frame
	15 in stdin. The gradient is stored in all channels
	16 of the video.
	17 .P
	18 The video in stdin must contain exactly 2 or 3
	19 pixels per frame. The first pixel shall point to
	20 the beginning of the gradient (where the value is
	21 0) and the second pixel shall point to the end of
	22 the gradient (where the value is 1). In these
	23 pixels, the value of the first channel specifies
	24 the X-position and the value of the second
	25 channel specifies Y-position, the other channels
	26 are ignored.
	27 .P
	28 If there is a third pixel, in frames in stdin, all
	29 values in the gradient are multipled by the value
	30 in the second channel (the Y channel) of the third
	31 pixel in stdin; the rest of the channels in this
	32 pixel is ignored.
	33 .SH OPTIONS
	34 .TP
	35 .B -a
	36 Make the gradient increase anticlockwise
	37 instead of clockwise.
	38 .TP
	39 .B -s
	40 Make the gradient increase symmetrically
	41 instead of clockwise.
	42 .TP
	43 .BR -w " "\fIwidth\fP
	44 The width of the video, in pixels.
	45 .TP
	46 .BR -h " "\fIheight\fP
	47 The height of the video, in pixels.
