98 * The size of one of the gamma LUT textures in any one dimension along
104 * These are the texture object handles for the gamma and inverse gamma
280 * So instead we build two 3D textures containing gamma (and inverse gamma)
315 // gamma adjust the dest color using the invgamma LUT
319 // gamma re-adjust the resulting color (alpha is always set to 1.0)
363 * Initializes a 3D texture object for use as a three-dimensional gamma
401 * (Re)Initializes the gamma lookup table textures.
405 * that essentially calculates pow(x, gamma) and the other calculates
406 * pow(x, 1/gamma). These values are replicated in all three dimensions, so
412 * where g is either gamma or 1/gamma, depending on the table.
417 double gamma = ((double)contrast) / 100.0;

470 * Updates the current gamma-adjusted source color ("src_adj") of the LCD
475 * gamma-adjusted value once and update the uniform parameter of the LCD
481 double gamma = ((double)contrast) / 100.0;

515 * gamma lookup table textures.
