HLSL-Related Enable Switches ---------------------------- Name Values Description hlsl_enable 0/1 Enables HLSL post-processing in Direct3D 9 modes. yiq_enable 0/1 Enables YIQ-colorspace post-processing. Causes a performance drop but gives a much more authentic NTSC TV appearance on TV-based systems when configured properly. hlslpath [path] Path to the .fx files that are in use. Color-Processing Parameters --------------------------- Name Values Description red_from_r -2.0 to 2.0 These parameters define a 3x3 matrix which is multiplied red_from_g -2.0 to 2.0 by the incoming RGB signal. This can be used for any red_from_b -2.0 to 2.0 standard matrix convolution, including H/S/V or simply green_from_r -2.0 to 2.0 affecting the TV-style tint. green_from_g -2.0 to 2.0 green_from_b -2.0 to 2.0 blue_from_r -2.0 to 2.0 blue_from_g -2.0 to 2.0 blue_from_b -2.0 to 2.0 red_scale -2.0 to 2.0 These parameters define a value for each color channel green_scale -2.0 to 2.0 that is multiplied with said channel after matrix blue_scale -2.0 to 2.0 convolution. red_offset -1.0 to 1.0 These parameters define a value for each color channel green_offset -1.0 to 1.0 that is added to said channel after scaling and after blue_offset -1.0 to 1.0 matrix convolution. saturation 0.0 to 4.0 This parameter defines the amount each color channel is raised above said channel's baseline grayscale value. A value of 0.0 gives a gamma-correct grayscale image, whereas 1.0 is full saturation, with each channel being oversaturated equally beyond that. red_power -4.0 to 4.0 These parameters define the exponent for each color green_power -4.0 to 4.0 channel that is applied after scaling, offsetting, blue_power -4.0 to 4.0 saturation and matrix convolution. red_floor 0.0 to 1.0 These parameters define the lower limit of each final green_floor 0.0 to 1.0 color channel value; 0.05, for example, raises the blue_floor 0.0 to 1.0 minimum to 0.05 but re-scales to leave the max at 1.0. Convergence-Processing Parameters --------------------------------- Name Values Description red_converge_x -150 to 150 These parameters define the overall convergence, in pixel red_converge_y -150 to 150 space, for each channel. Radial convergence occurs green_converge_x -150 to 150 relative to the center of the screen, whereas the other green_converge_y -150 to 150 six define overall translation values. blue_converge_x -150 to 150 blue_converge_y -150 to 150 red_radial_converge_x -150 to 150 red_radial_converge_y -150 to 150 green_radial_converge_x -150 to 150 green_radial_converge_y -150 to 150 blue_radial_converge_x -150 to 150 blue_radial_converge_y -150 to 150 defocus_x 0.0 to 32.0 These parameters define the overall defocus radius for defocus_y 0.0 to 32.0 the three post-converged beams. Front-Surface Processing Parameters ----------------------------------- Name Values Description red_phosphor_life 0.0 to 1.0 These parameters define the phosphor lifetime for each green_phosphor_life 0.0 to 1.0 channel, with 0.0 representing no phosphorescence and blue_phosphor_life 0.0 to 1.0 1.0 leaving the channel on indefinitely. scanline_alpha 0.0 to 1.0 The overall darkness of each scanline furrow. scanline_size 0.0 to 4.0 The overall height of each scanline. scanline_bright_scale 0.0 to 2.0 The overall brightness multiplier for each scanline. scanline_bright_offset 0.0 to 1.0 The overall brightness additive value for each scanline. scanline_jitter 0.0 to 2.0 The relative scanline movement per field. shadow_mask_alpha 0.0 to 1.0 The ovearll darkness of each shadow mask pixel. shadow_mask_texture [filename] A PNG that defines the shadow mask for each pixel. shadow_mask_x_count 1+ The count of shadow mask elements, X (usually 640-ish) shadow_mask_y_count 1+ The count of shadow mask elements, X (usually 480-ish) shadow_mask_usize 0.0 to 1.0 These parameters define the *in-use* pixel count on the shadow_mask_vsize 0.0 to 1.0 X and Y axes of the shadow mask texture. curvature 0.0 to 1.0 Screen curvature. Affects borders and shadow mask. pincushion 0.0 to 1.0 Image curvature. Affects the source image only. oversample_x 1.0 to 4.0 These parameters define a multiplier for each axis of the oversample_y 1.0 to 4.0 internal render target. Powerful GPU necessary.
