Public Attributes
float	width = 0
	Advance width of the text.

float	line_height = 0
	Recommended line spacing (ascent + descent + leading).
float	actual_bounding_box_left = 0
	Distance from text origin to the left edge of the rendering bounding box.
float	actual_bounding_box_right = 0
	Distance from text origin to the right edge of the rendering bounding box.
float	actual_bounding_box_ascent = 0
	Distance from baseline to top of the rendering bounding box.
float	actual_bounding_box_descent = 0
	Distance from baseline to bottom of the rendering bounding box.

Detailed Description

Full text metrics for layout and intrinsic sizing.

Mirrors HTML5 TextMetrics — fields beyond width/ascent/descent are the bounding-box-only metrics required by CanvasRenderingContext2D. All values are positive and in pixels at the current font size.

Member Data Documentation

actual_bounding_box_ascent

float pulp::canvas::Canvas::TextMetrics::actual_bounding_box_ascent = 0

Distance from baseline to top of the rendering bounding box.

actual_bounding_box_descent

float pulp::canvas::Canvas::TextMetrics::actual_bounding_box_descent = 0

Distance from baseline to bottom of the rendering bounding box.

actual_bounding_box_left

float pulp::canvas::Canvas::TextMetrics::actual_bounding_box_left = 0

Distance from text origin to the left edge of the rendering bounding box.

Positive when the bounding box extends left of the origin.

actual_bounding_box_right

float pulp::canvas::Canvas::TextMetrics::actual_bounding_box_right = 0

Distance from text origin to the right edge of the rendering bounding box.

ascent

float pulp::canvas::Canvas::TextMetrics::ascent = 0

Distance above baseline (positive value, ==fontBoundingBoxAscent).

descent

float pulp::canvas::Canvas::TextMetrics::descent = 0

Distance below baseline (positive value, ==fontBoundingBoxDescent).

line_height

float pulp::canvas::Canvas::TextMetrics::line_height = 0

Recommended line spacing (ascent + descent + leading).

width

float pulp::canvas::Canvas::TextMetrics::width = 0

Advance width of the text.
