Member Function Documentation

◆ encodeSymbolFlags()

std::uint32_t PointSymbolRenderer::encodeSymbolFlags ( float  alpha,
float  scale,
float  rotation,
float  hAnchor,
float  vAnchor,
bool  grayscale 
)
protected

Encode flags for scale, rotation, alpha, anchor alignment and grayscale. The flags are packed into 32 bits as follows: +----—+-----—+-----—+-------—+------—+-----—+ | alpha | Scale | Rotate | hAnchor | vAnchor | Misc. | +----—+-----—+-----—+-------—+------—+-----—+ 4b 8b 8b 5b 5b 2b

The "Misc" category currently only contains "grayscale" on the LSB.

◆ getSymbolRotation()

float Maria::PointSymbolRenderer::getSymbolRotation ( float  angle) const
inline

Get actual rotation angle for a point symbol which is rotated in 22.5 degree steps.

Parameters
angleInput angle, 0-360
Returns
Output angle snapped to nearest 22.5 degree interval.

◆ getSymbolSize()

float Maria::PointSymbolRenderer::getSymbolSize ( ) const
inline

Get point symbol size (in pixels).

◆ internalRemovePoints()

void PointSymbolRenderer::internalRemovePoints ( const std::vector< Maria::ItemId > &  itemIds)
protected

This is an internal version of removePoint, which assumes that an outer function has taken the mutex lock.

◆ removePoints()

void PointSymbolRenderer::removePoints ( const std::string &  listId = "")

Clear all points with the given list ID. If an empty list ID is given, all points are cleared.
