Detailed Description

This struct represents the metrics for a single glyph.

Todo:: (user): Consider using fractional units of a pixel for better sub-pixel positioning. (FreeType2 uses 1/64ths.)

Constructor & Destructor Documentation

ion::text::FreeTypeFont::GlyphMetrics::GlyphMetrics ( )

inline

The default constructor initializes everything to 0.

Definition at line 42 of file freetypefont.h.

bool ion::text::FreeTypeFont::GlyphMetrics::IsZeroSize ( ) const

inline

Returns true if glyph x- or y-size is zero.

Definition at line 46 of file freetypefont.h.

math::Vector2f ion::text::FreeTypeFont::GlyphMetrics::advance

Number of pixels to advance in X and Y to draw the next glyph after this.

Definition at line 57 of file freetypefont.h.

math::Vector2f ion::text::FreeTypeFont::GlyphMetrics::bitmap_offset

Distance in X and Y from the baseline to the top left pixel of the glyph bitmap, in pixels.

This should be added to the current position when drawing the glyph. The Y distance is positive for an upward offset.

Definition at line 54 of file freetypefont.h.

math::Vector2f ion::text::FreeTypeFont::GlyphMetrics::size

Width and height of the glyph, in pixels.

Definition at line 49 of file freetypefont.h.
