ROIBlockHeader::ROIBlockHeader (UINT16 v) [inline]

Constructor ✨

Parameters

  • v — Buffer size

Definition at line 196 of file PGFtypes.h.

196 { val = v; }

ROIBlockHeader::ROIBlockHeader (UINT32 size, bool end) [inline]

Constructor 💅

Parameters

  • size — Buffer size
  • end — 0/1 Flag; 1: last part of a tile

Definition at line 201 of file PGFtypes.h.

201 { ASSERT(size < (1 << RLblockSizeLen)); rbh.bufferSize = size; rbh.tileEnd = end; }
lowkey important: that ASSERT(size < (1 << RLblockSizeLen)) is right there in the source, so the buffer size has to stay under that bound. don't be the one who ignores it bestie 😭
