Function Documentation

fontHeight() [1/2]

int tgx::fontHeight

(

const GFXfont &

font

)

Query the height of a font.

overload for GFXfont.

Parameters

font

The font.

Returns

The number of vertical pixels between two lines of text with this font.

fontHeight() [2/2]

int tgx::fontHeight

(

const ILI9341_t3_font_t &

font

)

Query the height of a font.

overload for ILI9341_t3_font_t.

Parameters

font

The font.

Returns

The number of vertical pixels between two lines of text with this font.

measureChar() [1/2]

iBox2 tgx::measureChar	(	char	c,
		iVec2	pos,
		const GFXfont &	font,
		Anchor	anchor = DEFAULT_TEXT_ANCHOR,
		int *	xadvance = nullptr
	)

Compute the bounding box of a character.

overload for GFXfont.

Parameters

	c	The character.
	pos	position of the anchor point.
	font	The font to use.
	anchor	location of the anchor with respect to the char bounding box. (by default, this is the BASELINE|LEFT).
[in,out]	xadvance	If non-null, the number of pixel to advance horizontally after drawing the char is stored here.

Returns

the bounding box of pixels occupied by char c when draw with font when its chosen anchor is at pos.

measureChar() [2/2]

iBox2 tgx::measureChar	(	char	c,
		iVec2	pos,
		const ILI9341_t3_font_t &	font,
		Anchor	anchor = DEFAULT_TEXT_ANCHOR,
		int *	xadvance = nullptr
	)

Compute the bounding box of a character.

overload for ILI9341_t3_font_t.

Parameters

	c	The character.
	pos	position of the anchor point.
	font	The font to use.
	anchor	location of the anchor with respect to the char bounding box. (by default, this is the BASELINE|LEFT).
[in,out]	xadvance	If non-null, the number of pixel to advance horizontally after drawing the char is stored here.

Returns

the bounding box of pixels occupied by char c when draw with font when its chosen anchor is at pos.
