Detailed Description

Derivative of the GeneralTile which provides a two-level operator[] which will returns a strided pointer type.

Member Typedef Documentation

typedef ImageTileReadOnlyPtr DD::Image::DirectGeneralTile::RowPtr

pointer to within an individual row

Constructor & Destructor Documentation

DD::Image::DirectGeneralTile::DirectGeneralTile ( Iop &  input, const ChannelSet &  chans, bool  mt = false, InterestRatchet *  ir = nullptr  )

inline

load the entire requested area of /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.

DD::Image::DirectGeneralTile::DirectGeneralTile ( Iop &  input, const Box &  box, const ChannelSet &  chans, bool  mt = false, InterestRatchet *  ir = nullptr  )

inline

load the area /box/ on /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.

DD::Image::DirectGeneralTile::DirectGeneralTile ( Iop &  input, int  x, int  y, int  r, int  t, const ChannelSet &  chans, bool  mt = false, InterestRatchet *  ir = nullptr  )

inline

load the area (x, y, r, t) on /input/, for /channels/; if /mt/ is true then it may spawn threads to render the area in parallel. the InterestRatchet /ir/ might be passed down to the underlying RowCacheTile, if it uses one.

Member Function Documentation

LinePointers DD::Image::DirectGeneralTile::operator[] ( Channel  z ) const

inline

given a channel, return something that acts like an array of pointers to all the loaded lines

static RowPtr DD::Image::DirectGeneralTile::NilRow ( )

inlinestatic

return an empty row pointer
