Constructor Detail

TextBlobBuilder

@Internal
public TextBlobBuilder(long ptr)

TextBlobBuilder

public TextBlobBuilder()

Constructs empty TextBlobBuilder. By default, TextBlobBuilder has no runs.

Method Detail

build

@Nullable
public @Nullable TextBlob build()

Returns TextBlob built from runs of glyphs added by builder. Returned TextBlob is immutable; it may be copied, but its contents may not be altered. Returns null if no runs of glyphs were added by builder.

Resets TextBlobBuilder to its initial empty state, allowing it to be reused to build a new set of runs.

Returns:

SkTextBlob or null

appendRun

public TextBlobBuilder appendRun(Font font,
                                 java.lang.String text,
                                 float x,
                                 float y)

Glyphs are positioned on a baseline at (x, y), using font metrics to determine their relative placement.

Parameters:

font - Font used for this run

text - Text to append in this run

x - horizontal offset within the blob

y - vertical offset within the blob

Returns:

this

appendRun

public TextBlobBuilder appendRun(Font font,
                                 java.lang.String text,
                                 float x,

                                 @Nullable io.github.humbleui.types.Rect bounds)

Glyphs are positioned on a baseline at (x, y), using font metrics to determine their relative placement.

bounds defines an optional bounding box, used to suppress drawing when TextBlob bounds does not intersect Surface bounds. If bounds is null, TextBlob bounds is computed from (x, y) and glyphs metrics.

Parameters:

font - Font used for this run

text - Text to append in this run

x - horizontal offset within the blob

y - vertical offset within the blob

bounds - optional run bounding box

Returns:

this

appendRun

                                 @Nullable io.github.humbleui.types.Rect bounds)

Glyphs are positioned on a baseline at (x, y), using font metrics to determine their relative placement.

bounds defines an optional bounding box, used to suppress drawing when TextBlob bounds does not intersect Surface bounds. If bounds is null, TextBlob bounds is computed from (x, y) and glyphs metrics.

Parameters:

font - Font used for this run

glyphs - glyphs in this run

x - horizontal offset within the blob

y - vertical offset within the blob

bounds - optional run bounding box

Returns:

this

appendRunPosH

                                     float y)

Glyphs are positioned on a baseline at y, using x-axis positions from xs.

Parameters:

font - Font used for this run

glyphs - glyphs in this run

xs - horizontal positions on glyphs within the blob

y - vertical offset within the blob

Returns:

this

appendRunPosH
