Detailed Description

This structure contains some of the information that Iop::_validate() and DeepOp::_validate() must calculate. Because this information is often copied unchanged or with tiny variations from the input operator, it is put into this structure so that it can be copied with a single assignment.

This is a subclass of Box and that provides x,y,r,t values that describe the bounding box around all the interesting pixels (that is, the region of definition). It also provides a merge and intersect operators that are useful when _validate is combining the info from two inputs.

constructor

Member Function Documentation

◆ format()

void DD::Image::Info2D::format ( const Format f)
inline

Sets info_.format() to the given format. Some operators expect this to tell them how to size their output. Most operators will overwrite this in their _validate() method.

◆ full_size_format() [1/2]

const Format & DD::Image::Info2D::full_size_format ( ) const
inline

If the output of this operator is a proxy for a full size image, this is the full size. Nuke assumes all coordinates are given in the full size and scales them to the format() when storing them into the knob locations. Because Nuke does the scaling most operators can ignore this, it is occasionally useful for undoing the scaling to get the user's original numbers.

If this is not a proxy then this should point at the same location as format().

◆ full_size_format() [2/2]

void DD::Image::Info2D::full_size_format ( const Format f)
inline

Sets info_.full_size_format() to the given format. Some operators expect this to tell them how to size their output. Most operators will overwrite this in their _validate() method.
