Fields
| Field | Purpose |
|---|---|
GroupCount | Transparency groups rendered during the pass |
TileCount | Individual tiles rendered across those groups |
PeakTilePixels | Pixel count of the largest tile rendered |
PeakWorkingBytes | Largest tile working set reached while tiling |
UntiledPeakWorkingBytes | Working set the largest group would have needed without tiling |
Usage notes
- Render entry points fill the matching out parameters, and the last values stay readable through
THotPDF.GetLastTransparencyGroupTileStats - Compare
