Detailed Description

Row contains intermediate data per pixel for a single image row. It is used during updating to encode pixels.

Member Enumeration Documentation

PixelType

enum class blender::bke::pbvh::pixels::Rows::PixelType

strong

Enumerator
Undecided
Brush	This pixel is directly affected by a brush and doesn't need to be solved.
SelectedForCloserExamination
CopyFromClosestEdge	This pixel will be copied from another pixel to solve non-manifold edge bleeding.

find_second_source()

int2 blender::bke::pbvh::pixels::Rows::find_second_source ( int2 destination, int2 first_source )

inline

Look for a second source pixel that will be blended with the first source pixel to improve the quality of the fix.

• The second source pixel must be a neighbor pixel of the first source, or the same as the first source when no second pixel could be found.
• The second source pixel must be a pixel that is painted on by the brush.
• The second source pixel must be the second closest pixel, or the first source when no second pixel could be found.

Mark pixels that are painted on by the brush. Those pixels don't need to be updated, but will act as a source for other pixels.
