Detailed Description

Constraints to tile size and width to height ratio.

Member Function Documentation

◆ getBest()

NSize stmg::TileSizing::getBest ( int32_t nReqW ) const

noexcept

Calculates the best tile size given a requested width.

The resulting size might not satisfy the constraints because they can't.

Parameters

nReqW The requested width.

Returns: The tile size.

◆ isValid()

bool stmg::TileSizing::isValid ( ) const

noexcept

Member Data Documentation

◆ m_fWHRatio

double stmg::TileSizing::m_fWHRatio = 1.0

The fixed width to height ratio.

Minimum is 0.001. Maximum is 1000.0. Default is 1.

◆ m_nMaxH

int32_t stmg::TileSizing::m_nMaxH = 1000

Maximum height in pixels.

Cannot be smaller than m_nMinH. Default is 1000.

◆ m_nMaxW

int32_t stmg::TileSizing::m_nMaxW = 1000

Maximum width in pixels.

Cannot be smaller than m_nMinW. Default is 1000.

◆ m_nMinH

int32_t stmg::TileSizing::m_nMinH = 5

Minimum height in pixels.

Must be positive. Default is 5.

◆ m_nMinW

int32_t stmg::TileSizing::m_nMinW = 5

Minimum width in pixels.
