SkTypeface (Style style, uint32_t uniqueID) |
The SkTypeface class specifies the typeface and intrinsic style of a font. This is used in the paint, along with optionally algorithmic settings like textSize, textSkewX, textScaleX, kFakeBoldText_Mask, to specify how text appears when drawn (and measured).
Typeface objects are immutable, and so they can be shared between threads.

enum SkTypeface::Style |
Style specifies the intrinsic style attributes of a given typeface
Definition at line 38 of file SkTypeface.h.
SkTypeface::SkTypeface | ( | Style | style, | |
uint32_t | uniqueID | |||
) | [inline, protected] |
uniqueID must be unique (please!) and non-zero
Definition at line 124 of file SkTypeface.h.
static SkTypeface* SkTypeface::CreateFromFile | ( | const char | path[] | ) | [static] |
Return a new typeface given a file. If the file does not exist, or is not a valid font file, returns null.
static SkTypeface* SkTypeface::CreateFromName | ( | const char | familyName[], | |
Style | style | |||
) | [static] |
Return a new reference to the typeface that most closely matches the requested familyName and style. Pass null as the familyName to return the default font for the requested style. Will never return null
familyName | May be NULL. The name of the font family. | |
style | The style (normal, bold, italic) of the typeface. |
static SkTypeface* SkTypeface::CreateFromStream | ( | SkStream * | stream | ) | [static] |
Return a new typeface given a stream. If the stream is not a valid font file, returns null. Ownership of the stream is transferred, so the caller must not reference it again.
static SkTypeface* SkTypeface::CreateFromTypeface | ( | const SkTypeface * | family, | |
Style | s | |||
) | [static] |
Return a new reference to the typeface that most closely matches the requested typeface and specified Style. Use this call if you want to pick a new style from the same family of the existing typeface. If family is NULL, this selects from the default font's family.
family | May be NULL. The name of the existing type face. | |
s | The style (normal, bold, italic) of the type face. |
static SkTypeface* SkTypeface::Deserialize | ( | SkStream * | ) | [static] |
Given the data previously written by serialize(), return a new instance to a typeface referring to the same font. If that font is not available, return null. If an instance is returned, the caller is responsible for calling unref() when they are done with it.
static bool SkTypeface::Equal | ( | const SkTypeface * | facea, | |
const SkTypeface * | faceb | |||
) | [static] |
Returns true if the two typefaces reference the same underlying font, handling either being null (treating null as the default font)
bool SkTypeface::isBold | ( | ) | const [inline] |
Returns true if getStyle() has the kBold bit set.
Definition at line 53 of file SkTypeface.h.
bool SkTypeface::isItalic | ( | ) | const [inline] |
Returns true if getStyle() has the kItalic bit set.
Definition at line 57 of file SkTypeface.h.
void SkTypeface::serialize | ( | SkWStream * | ) | const |
Write a unique signature to a stream, sufficient to reconstruct a typeface referencing the same font when Deserialize is called.
Style SkTypeface::style | ( | ) | const [inline] |
Returns the typeface's intrinsic style attributes
Definition at line 49 of file SkTypeface.h.
static uint32_t SkTypeface::UniqueID | ( | const SkTypeface * | face | ) | [static] |
Return the uniqueID for the specified typeface. If the face is null, resolve it to the default font and return its uniqueID. Will never return 0.
uint32_t SkTypeface::uniqueID | ( | ) | const [inline] |
Return a 32bit value for this typeface, unique for the underlying font data. Will never return 0.
