Claim 0:
1. A method implemented by a computing device, the method comprising:
obtaining digital visual content;
obtaining a lookup table generated using a curve defining a pixel transformation applied to one or more pixels of the digital visual content to create transformed digital visual content, the lookup table generated by:
deriving samples at evenly spaced intervals along a y-axis relative to the curve and identifying, for each of the derived samples, a value relative to the curve along an x-axis;
designating evenly spaced sample values along the x-axis and, for each of the sample values, defining an index value for the lookup table using a largest one of the identified values relative to the curve along the x-axis not greater than the sample value; and
generating a slope parameter portion for the lookup table that includes a plurality of slope values, each of the plurality of slope values specifying a slope between consecutive ones of the index values; and

generating the transformed digital visual content using the lookup table.
