- merged YIQ encode and decode pass into one NTSC pass - added options for most NTSC settings - reduced sample count to 64 - changed default O value to 0 - fit NTSC signal jitter between a reasonable limit of 0 and 1 - fit A and B value between a reasonable limit of -1 and 1 - fit scanline jitter between a reasonable limit of 0 and 1 - added hum bar simulation based on [MooglyGuy's] GLSL port of the mame shader pipeline - added monochrome-chessboard.png - added slot-mask-aligned.png (to simulate a TFT LCD)

|
|
Allowed values for convergence: -10.0 to 10.0 for each color.
|
|
red_ratio [r,g,b] These parameters define a 3x3 matrix which is multiplied
|
|
grn_ratio [r,g,b] by the incoming RGB signal. This can be used for any
|
|
blu_ratio [r,g,b] standard matrix convolution, including H/S/V or simply
|
|
affecting the TV-style tint.
|
|
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.
|
|

|
|
matrix convolution. (-2.0 to 2.0)

that is multiplied with said channel after matrix
|
|
convolution. (-2.0 to 2.0)

|
|
channel that is applied after scaling, offsetting,
|
|
saturation and matrix convolution. (-4.0 to 4.0)
|
|
floor [r,g,b] These parameters define the lower limit of each final
|
|
color channel value; 0.05, for example, raises the
|
|
minimum to 0.05 but re-scales to leave the max at 1.0.
|
|
phosphor_life [r,g,b] These parameters define the phosphor lifetime for each
|
|
channel, with 0.0 representing no phosphorescence and
|
|
1.0 leaving the channel on indefinitely. Values allowed
|
|
range from 0.0 to 1.0.
