Ticket #4858, comment 1
initial v1 6 6 3  The order of color channels in the file: value, red, green, blue, alpha. 7 7 4  If curvetype smooth is set, then coordinates of points must be read from section (points 34 from the beginning, negative values must be ignored, positive values follow in pair (x y) correspond to the ffmpeg coordinates x/y. 1.000000 0.240854 0.139194 1.000000 means 0.240854/0.139194 for ffmpeg, 0.045714 0.045249 0.091429 0.095023 means 0.045714/0.045249 0.091429/0.095023 for ffmpeg. 8 5  If curvetype free is set, then coordinates of points must be read from section (samples 256. There are only y coordinates arestated, so x coordinate is calculated by the following formula: x1=0, x2=1/255, x3=2/255, x4=3/255,...,x256=18 5  If curvetype free is set, then coordinates of points must be read from section (samples 256. There are only y coordinates stated, so x coordinate is calculated by the following formula: x1=0, x2=1/255, x3=2/255, x4=3/255,...,x256=1 9 9 6  All points coordinates pairs follow strictly (for both curve types) x coordinate ascending order.
