=== Processing Normal Maps ===
If the input image is a normal map, it may require some special treatment. For example, you don't want to gamma correct it. To indicate that the input image is a normal map the following method is available:
{{{
void InputOptions::setNormalMap(bool isNormalMap);
}}}
The convolution filter used for mipmap generation generally produces normals that are not unit length. The following method allows you to do that:
{{{
void InputOptions::setNormalizeMipmaps(bool normalizeMipmaps);
}}}
*TODO*: Default the value for `normalizeMipmaps` should be true, but it should only be valid when `isNormalMap` is true.
*TODO*: Is this the default when normalMap is true? What if convertToNormalMap is true?
=== Generating Normal Maps ===
*TODO*
*TODO*: Only input image is converted to normal map. After that, mipmap generation is done on the normal map directly.
{{{
inputOptions.convertToNormalMap(true);
}}}
