FONSTextBoundsIterator

This iterator can be used to do text measurement.

Don't add new fonts to stash while you are iterating, or you WILL get segfault!

struct FONSTextBoundsIterator {

this(FONSContext astash, float ax, float ay);

void reset(FONSContext astash, float ax, float ay);

bool valid [@property getter];

void put(const(T)[] str);

float advance [@property getter];

void getBounds(float[4] bounds);

void getHBounds(float xmin, float xmax);

void getVBounds(float ymin, float ymax);

float lineHeight();

float ascender();

float descender();

}

Constructors

this this(FONSContext astash, float ax, float ay): Initialize iterator with the current FontStash state. FontStash state can be changed after initialization without affecting the iterator.

Members

Functions

ascender float ascender(): Returns font ascender (positive).
descender float descender(): Returns font descender (negative).
getBounds void getBounds(float[4] bounds): Returns current text bounds.
getHBounds void getHBounds(float xmin, float xmax): Returns current horizontal text bounds.
getVBounds void getVBounds(float ymin, float ymax): Returns current vertical text bounds.
lineHeight float lineHeight(): Returns font line height.
put void put(const(T)[] str): Put some text into iterator, calculate new values.
reset void reset(FONSContext astash, float ax, float ay): (Re)initialize iterator with the current FontStash state. FontStash state can be changed after initialization without affecting the iterator.

Properties

advance float advance [@property getter]: Returns current advance.
valid bool valid [@property getter]: Can this iterator be used?
