Detailed Description

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

Use of this means that the data from the input will have to be unpacked if it is provided packed, so it is probably best avoided and provided solely for compatibility

Member Typedef Documentation

typedef const float* DD::Image::RawGeneralTile::RowPtr

pointer to within an individual row

Constructor & Destructor Documentation

DD::Image::RawGeneralTile::RawGeneralTile ( 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::RawGeneralTile::RawGeneralTile ( 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::RawGeneralTile::RawGeneralTile ( 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::RawGeneralTile::operator[] ( Channel  z) const
inline

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

static const float* DD::Image::RawGeneralTile::NilRow ( )
inlinestatic

return an empty row pointer
