Reel.Deal: DGTonemap: add documentation

<p>DGTonemap: add documentation</p>

== Description ==<br />
DGTonemap provides filters for Reinhard and Hable tonemapping operators. This<br />
is a starting point to make available a full HDR->SDR process for [[AviSynth+]].<br><br />
<br><br />
<br />
== Requirements ==<br />
* [[AviSynth+]] (x86 and x64)<br />
* Supported color formats: [[RGBPS]]<br />
<br><br />
<br />
== [[Script variables|Syntax and Parameters]] ==<br />
<br />
===Reinhard Usage===<br />
:{{Template:FuncDef|DGReinhard (clip, float "contrast", float "bright")}}<br />
<br><br />
::{{Par2| |clip| }}<br />
:::Input clip; the filter receives and delivers the RGBPS color space. See [[Avsresize#z_ConvertFormat|z_ConvertFormat()]] in the sample script below. <br />
<br><br />
::{{Par2|contrast|float|5.0}}<br />
:::Contrast<br />
<br><br />
::{{Par2|contrast|float|0.3}}<br />
:::Higher numbers for <code>bright</code> reduce brightness, you can even go to <code>bright=1000</code> and beyond, but it stops having an effect up there.<br />
<br><br />
===Hable Usage===<br />
:{{Template:FuncDef|DGHable (clip, float "exposure", float "a", float "b", float "c", float "d", float "e", float "f", float "w")}}<br />
<br><br />
::{{Par2| |clip| }}<br />
:::Input clip; the filter receives and delivers the RGBPS color space. See [[Avsresize#z_ConvertFormat|z_ConvertFormat()]] in the sample script below. <br />
<br><br />
::{{Par2|exposure|float|2.0}}<br />
:::Gain to apply.<br />
<br><br />
::{{Par2|a|float|0.15}}<br />
:::a: Shoulder strength<br />
::{{Par2|b|float|0.50}}<br />
:::b: Linear strength<br />
::{{Par2|c|float|0.10}}<br />
:::c: Linear angle<br />
::{{Par2|d|float|0.20}}<br />
:::d: Toe strength<br />
::{{Par2|e|float|0.02}}<br />
:::e: Toe numerator<br />
::{{Par2|f|float|0.30}}<br />
:::f: Toe denominator<br />
::{{Par2|w|float|11.2}}<br />
:::w: Linear white point<br />
<br><br />
::<code>hable(x) = ((x*(a*x+c*b)+d*e) / (x*(a*x+b)+d*f)) - e/f</code><br />
::<code>output_pixel = hable(exposure * input_pixel) / hable(w)</code><br />
<br><br />
<br />
== Examples ==<br />
Following is a sample script for the full HDR->SDR process. The source UHD video is tonemapped, converted to rec709 colorspace, and downsampled to 8 bits. To leave it in 16 bits, set <code>pixel_type=YUV420P16</code> in the second z_ConvertFormat() call.<br />
<br />
<pre><br />
SetFilterMTMode("z_ConvertFormat", MT_MULTI_INSTANCE) # May not be needed.<br />
DGSource("THE GREAT WALL.dgi",fulldepth=true)<br />
ConvertBits(10) # Use 12 for 12-bit<br />
z_ConvertFormat(pixel_type="RGBPS",colorspace_op="2020ncl:st2084:2020:l=>rgb:linear:2020:l", dither_type="none")<br />
# Choose one of these:<br />
DGReinhard()<br />
#DGHable()<br />
z_ConvertFormat(pixel_type="YV12",colorspace_op="rgb:linear:2020:l=>709:709:709:l",dither_type="ordered")<br />
