template<typename OperandT>
class ImFusion::ImageMath::MaskLeaf< OperandT >
Use a Mask/GlMask as an ImageMath leaf that can be used in ImageMath expressions.
The "value" parameter for the mask is itself an ImageMath expression.
- Warning
- GlMasks expect their "value" parameter in normalized storage convention, Masks expect their "value" in storage convention. ImageMath typically works in (unnormalized) original convention,
- See also
- ImageDescriptor The normalization is performed with the pixelType of the expression's ImageDescriptor, it is the responsibility of the user to verify that this yields something that the mask expects. The original->storage conversion must be performed by the user. Users must be aware of the fact that value domain conversions can result in rounding errors.
Example usage, here si is a SharedImage
m->setRoundness(100);
auto derivedExpr = (maskLeaf > 0).
select(1.0,2.0);

- Warning
- Using different underlying types or shift+scale values in the operand will give undefined results for masks that depend on the operand.
