Fog Ino\medskip

\par

\normalsize

It scatters light.\\

\par

Used for bath water, and mist, etc.,\par

A directional Light creates the appearance of the (Light Scattering) effect.\par

The optical filter, and fog, such as diffusion\par

can be aimed at by the effect, but it does not have to simulate the light.\\

\par

Each pixel, is affected by the shining of a more bright surrounding pixel.\par

More strongly from nearby pixels, it will have a weaker impact from distant pixels.\\

\par

First, \textquotedbl Alpha Rendering\textquotedbl \ processing starts if the Alpha channel is ON,\par

next, it handles the RGB pixels when the Alpha channel is not zero.\\

\par

\textquotedbl Alpha Rendering\textquotedbl \ is not handled when the Alpha channel is OFF,\par

it does not Mask changes in the RGB image, so you will get jaggies on the mask edge.\\

Radius\par

The extent of which to scatter the light, specified by a circle radius.\par

The unit is millimeters.\par

Specify a value greater than or equal to 0. The maximum is 100.\par

When a Pixel is smaller than the width value, it is not affected, Fog will not be applied.\par

A larger Radius will take more time to process.\par

The default value is 1.\\

\\

Curve\par

The attenuation curve going towards the scattered light.\par

Specify a value of 0.01 or more. The maximum is 100.\par

The effect will be weaker on pixels further away,\par

it represents the change in the Gamma curve.\par

Brightness in the case of 1.0 is linear attenuated.\par

The smaller the value the lower the brightness becomes (impact is reduced abruptly),\par

a larger bulge will produce a higher brightness (impact is emphasized).\par

The default value is 1.

\par

\noindent Power\par

Changes the strength to disperse the light.\par

Specify a value in the range 0 to 1.\par

You can specify values above 1.0 up to a maximum 2.0, it will emphasize the light.\par

The emphasis may be useful to emit light from a dark portion such as an ink line.\par

When the value is 0.0 pixels will not be affected by the light, Fog will not be applied.\par

You can specify values less than 0.0 down to a minimum of -2.0.\par

Processing with this is not the scattering of light, it will be the scattering of darkness.\par

The default value is 1.\\

\\

Threshold Min\\

Threshold Max\par

Specify these values to get more brightness from the emitted Pixel light.\\

\par

Affected by the brightness from a more bright Pixel, but in addition to that,\par

using the Pixel value (\textquotedbl Threshold Min\textquotedbl ) can get even more brightness,\par

to affect the current overall brightness.\par

Brightness, is determined from the RGB Pixel value (of HLS) from the L value.\\

\par

The following range greater than or equal to 0.0 to 1.01 can be specified as values.\\

\par

If both values are 1.01 Fog will not be applied.\\

\par

If \textquotedbl Threshold Max\textquotedbl \ is greater than \textquotedbl Threshold Min\textquotedbl ,\par

it carries out smooth changes in fog by linear interpolation between Min and Max.\\

\par

Reversing \textquotedbl Threshold Max\textquotedbl \ (which may be less than Min) but kept above 0,\par

will suddenly emit light from pixels with \textquotedbl Threshold Min\textquotedbl \ or more of brightness.\par

\textquotedbl Threshold Min\textquotedbl \ also produces full Fog if set to 0.\\

\par

The default value is 0 for both.\\

\\

Alpha Rendering\par

Switch is only valid when there is an Alpha channel in the image.\par

When OFF it does not do anything.\par

When ON it will also process the Alpha channel.\par

The default setting is OFF.
