kzsError kzuBitmapFontCreateFromResource ( struct KzuBitmapFontSystem bitmapSystem,
kanzi::Domain domain,
kzString  resourcePath,
struct KzuBitmapFont **  out_bitmapFont 
)

Creates new font from resource.

KANZI_API kzsError kzuBitmapFontCreateFromMemory ( struct KzuBitmapFontSystem bitmapSystem,
kanzi::Domain domain,
kzString  fntFileContent,
struct KzuBitmapFont **  out_bitmapFont 
)

Creates new font from preloaded resources.

kzsError kzuBitmapFontLoadFromKZB ( struct KzuBitmapFont bitmapFont,
struct KzcInputStream inputStream,
const struct KzuBinaryFileInfo file 
)

struct KzuBitmapFont* kzuBitmapFontFromFont ( struct KzuFont font)

Type cast from generic font to bitmap font.

struct KzuFont* kzuBitmapFontToFont ( struct KzuBitmapFont bitmapFont)

Type cast from bitmap font to generic font.

struct KzcDynamicArrayIterator kzuBitmapFontGetFontTextureNames ( const struct KzuBitmapFont bitmapFont)

Gets font texture names from font.

KANZI_API void kzuBitmapFontSetTexture ( KzuBitmapFont bitmapFont,

Returns the descender of bitmap font.

kzUint kzuBitmapFontGetGlyphIndex ( const struct KzuBitmapFont bitmapFont,
kzUnicodeChar  character 
)

Returns the glyph index in the font for the given unicode code point.

void kzuBitmapFontGetCharacterMetrics ( const struct KzuBitmapFont bitmapFont,
kzUint  glyphIndex,
kzFloat out_advance,
struct KzcRectangle out_boundingBox 
)

Returns the advance of given character using bitmap font.

kzFloat kzuBitmapFontGetKerning ( const struct KzuBitmapFont bitmapFont,
kzUint  previousGlyphIndex,
kzUint  glyphIndex 
)

Returns the kerning of given character pair using bitmap font.

kzsError kzuBitmapFontDrawCharacter ( const struct KzuBitmapFont bitmapFont,
kanzi::Renderer renderer,
kzUint  glyphIndex,
kzFloat  x,
kzFloat  y 
)

Draws a character at given coordinates.

The coordinates indicate the character left point on the baseline. This function is meant for debugging purposes only. For real text rendering, use KzcTextLayouter.

kzsError kzuBitmapFontPrepareTextLayout ( struct KzuTextLayout textLayout,
kanzi::Renderer renderer 
)

Prepares the given pre-layouted text for fast rendering using bitmap font.

kzsError kzuBitmapFontDrawTextLayout ( struct KzuTextLayout textLayout,
kanzi::Renderer renderer,
kzFloat  x,
kzFloat  y 
)

Draw the given pre-layouted text using bitmap font.

kzsError kzuBitmapFontDrawTextLayout3D ( struct KzuTextLayout textLayout,
kanzi::Renderer renderer 
)

Draw the given pre-layouted text in 3D space using bitmap font.

kzsError kzuBitmapFontFreeTextLayoutData ( struct KzuTextLayout textLayout)

Frees the data and resources created by the prepare function.
