GlyphData Struct Reference

Cached per-glyph metrics and rasterized texture, keyed by (pixel size, char code) in GuiTextRenderer::fontData. More...

#include <GuiTextRenderer.h>

Public Attributes
int16_t	renderOffsetX = 0
	Horizontal offset from the pen position to the bitmap's left edge.
uint16_t	glyphAdvanceX = 0
	Horizontal pen advance after this glyph.
uint16_t	glyphAdvanceY = 0
	Vertical pen advance after this glyph.
uint32_t	glyphIndex = 0
	FreeType glyph index.
uint16_t	textureWidth = 0
	Pixel dims of the rasterized bitmap/texture, at uiScale - always >= drawWidth/drawHeight, and equal to them when uiScale is 1.0.
uint16_t	textureHeight = 0
	Height counterpart of textureWidth.
uint16_t	drawWidth = 0
	Design-pixel dims to actually draw the quad at (textureWidth/Height divided back down by uiScale) - keeps text laid out and sized identically to uiScale 1.0 while the texture itself is crisper.
uint16_t	drawHeight = 0
	Height counterpart of drawWidth.
int16_t	renderOffsetY = 0
	Height of the bitmap's top edge above the baseline.
int16_t	renderOffsetMax = 0
	Height of the glyph bitmap above the baseline (feeds FontOffset::max)
int16_t	renderOffsetMin = 0
	Depth of the glyph bitmap below the baseline (feeds FontOffset::min)
void *	texture = nullptr
	Abstracted texture pointer.
