Detailed Description

A class to store attributes needed for label rendering.

Label attributes: border (color, width, style) / / text bounding box / / +--------—/–+ buffer (color, pattern) | / | / | +-—+ |/ –+ | |Text| / |— text size | +-—+ /| –+ | | +-----------—+ | | | | >|-—|<— buffer width | >|<— border width

Text:

• font family
• size type (map units, points)
• size (in points - device independent)
• bold
• italic
• underline
• color

Position:

• (coordinates)
• offset type (map units, points)
• x offset, y offset (measured in text coordinate system, not in map coordinate system)
• angle
• alignment (from a point calculated by angle and offset)

Buffer:

• buffer size type (map units, points)
• buffer size
• buffer color
• buffer brush

Border:

• border width
• border color
• border style

Each attribute is either set or unset.
