| SubRect* CS::SubRectangles::SubRect::Alloc | ( | int | w, | |
| int | h, | |||
| const AllocInfo & | ai, | |||
| csRect & | r | |||
| ) | [protected] |
Do the actual allocation.
| void CS::SubRectangles::SubRect::DecideBestSplit | ( | const csRect & | rect, | |
| int | splitX, | |||
| int | splitY, | |||
| SubRect::SplitType & | splitType | |||
| ) | [protected] |
Decide whether a H or V split is better.
The better split is the one where the bigger chunk results.
