Member Data Documentation

◆ SizeProperty

PropertyType<float> kanzi::FontStyleConcept::SizeProperty
static

Sets the size for the font in pixels.

The default value is 36.0f.

◆ StyleProperty

PropertyType<FontStyle> kanzi::FontStyleConcept::StyleProperty
static

Sets the style for the font.

The default value is FontStyle::Normal.

◆ WeightProperty

PropertyType<FontWeight> kanzi::FontStyleConcept::WeightProperty
static

Sets the weight for the font.

The default value is FontWeight::Normal.

◆ CharacterSpacingProperty

PropertyType<float> kanzi::FontStyleConcept::CharacterSpacingProperty
static

Sets the character spacing in pixels.

The default value is 0.0f.

◆ FixedCharacterWidthProperty

PropertyType<float> kanzi::FontStyleConcept::FixedCharacterWidthProperty
static

Overrides the font advance widths and makes each character take a fixed amount of space specified in pixels.

The default value is -1.0f.

◆ LineSpacingProperty

PropertyType<float> kanzi::FontStyleConcept::LineSpacingProperty
static

Sets the line spacing in multiples of the normal line height of the selected font.

The default value is 1.0f.

◆ FractionalCharacterWidthProperty

PropertyType<bool> kanzi::FontStyleConcept::FractionalCharacterWidthProperty
static

Sets whether Kanzi uses fractional or rounded character widths to lay out text.

In most cases fractional widths provide the best result. However, with small font sizes, fractional widths can cause the characters to run together or have too much space, making it difficult to read.

  • When enabled, Kanzi uses fractional character widths, which means that the spacing between characters varies and can be a fraction of a pixel.
  • When disabled, Kanzi uses character widths rounded to the nearest pixel. Disable fractional widths when you want to fix character spacing in whole-pixel increments and prevent characters in small font sizes from running together. The default value is true.

◆ SnapCharacterToPixelProperty

PropertyType<bool> kanzi::FontStyleConcept::SnapCharacterToPixelProperty
static

Sets whether Kanzi positions characters in 2D rendering to the nearest pixel:

  • When enabled, text sharpness improves, but some characters can shift a fraction of a pixel.
  • When disabled, certain combinations of screen resolution, use of anti-aliasing, and font size can cause the text to appear blurry. In that case, you can improve the appearance of the text with the FractionalCharacterWidthProperty and CharacterSpacingProperty properties. The default value is true.

◆ HintingPreferenceProperty

PropertyType<FontHintingPreference> kanzi::FontStyleConcept::HintingPreferenceProperty
static

Sets the hinting preference of the selected font.

The default value is FontHintingPreference::NativeHinting.
