Int |
getOffsetForAdvance(text: CharArray!, start: Int, end: Int, contextStart: Int, contextEnd: Int, isRtl: Boolean, advance: Float)
Get the character offset within the string whose position is closest to the specified horizontal position.
The returned value is generally the value of offset for which #getRunAdvance yields a result most closely approximating advance, and which is also on a grapheme cluster boundary. As such, it is the preferred method for positioning a cursor in response to a touch or pointer event. The grapheme cluster boundaries are based on Unicode Standard Annex #29 but with some tailoring for better user experience.
Note that advance is a (generally positive) width measurement relative to the start of the run. Thus, for RTL runs it the distance from the point to the right edge.
All indices are relative to the start of text. Further, 0 <= contextStart <= start <= end <= contextEnd <= text.length must hold on entry, and start <= result <= end will hold on return.
|
Int |
getOffsetForAdvance(text: CharSequence!, start: Int, end: Int, contextStart: Int, contextEnd: Int, isRtl: Boolean, advance: Float)
|
PathEffect! |
getPathEffect()
Get the paint's patheffect object.
|
Float |
getRunAdvance(text: CharArray!, start: Int, end: Int, contextStart: Int, contextEnd: Int, isRtl: Boolean, offset: Int)
Measure cursor position within a run of text.
The run of text includes the characters from start to end in the text. In addition, the range contextStart to contextEnd is used as context for the purpose of complex text shaping, such as Arabic text potentially shaped differently based on the text next to it.
All text outside the range contextStart..contextEnd is ignored. The text between start and end will be laid out to be measured.
The returned width measurement is the advance from start to offset. It is generally a positive value, no matter the direction of the run. If offset == end, the return value is simply the width of the whole run from start to end.
Ligatures are formed for characters in the range start..end (but not for start..contextStart or end..contextEnd). If offset points to a character in the middle of such a formed ligature, but at a grapheme cluster boundary, the return value will also reflect an advance in the middle of the ligature. See #getOffsetForAdvance for more discussion of grapheme cluster boundaries.
The direction of the run is explicitly specified by isRtl. Thus, this method is suitable only for runs of a single direction.
All indices are relative to the start of text. Further, 0 <= contextStart <= start <= offset <= end <= contextEnd <= text.length must hold on entry.

|
Float |
getTextRunAdvances(chars: CharArray, index: Int, count: Int, contextIndex: Int, contextCount: Int, isRtl: Boolean, advances: FloatArray?, advancesIndex: Int)
Retrieve the character advances of the text. Returns the total advance width for the characters in the run from index for count of chars, and if advances is not null, the advance assigned to each of these characters (java chars).
The trailing surrogate in a valid surrogate pair is assigned an advance of 0. Thus the number of returned advances is always equal to count, not to the number of unicode codepoints represented by the run.
In the case of conjuncts or combining marks, the total advance is assigned to the first logical character, and the following characters are assigned an advance of 0.
This generates the sum of the advances of glyphs for characters in a reordered cluster as the width of the first logical character in the cluster, and 0 for the widths of all other characters in the cluster. In effect, such clusters are treated like conjuncts.
The shaping bounds limit the amount of context available outside start and end that can be used for shaping analysis. These bounds typically reflect changes in bidi level or font metrics across which shaping does not occur.
|
Int |
getTextRunCursor(text: CharArray, contextStart: Int, contextLength: Int, isRtl: Boolean, offset: Int, cursorOpt: Int)
Returns the next cursor position in the run. This avoids placing the cursor between surrogates, between characters that form conjuncts, between base characters and combining marks, or within a reordering cluster.
ContextStart and offset are relative to the start of text. The context is the shaping context for cursor movement, generally the bounds of the metric span enclosing the cursor in the direction of movement.
If cursorOpt is CURSOR_AT and the offset is not a valid cursor position, this returns -1. Otherwise this will never return a value before contextStart or after contextStart + contextLength.
|
Int |
getTextRunCursor(text: CharSequence, contextStart: Int, contextEnd: Int, isRtl: Boolean, offset: Int, cursorOpt: Int)
Returns the next cursor position in the run. This avoids placing the cursor between surrogates, between characters that form conjuncts, between base characters and combining marks, or within a reordering cluster.
ContextStart, contextEnd, and offset are relative to the start of text. The context is the shaping context for cursor movement, generally the bounds of the metric span enclosing the cursor in the direction of movement.
If cursorOpt is CURSOR_AT and the offset is not a valid cursor position, this returns -1. Otherwise this will never return a value before contextStart or after contextEnd.

Boolean |
hasGlyph(string: String!)
Determine whether the typeface set on the paint has a glyph supporting the string. The simplest case is when the string contains a single character, in which this method determines whether the font has the character. In the case of multiple characters, the method returns true if there is a single glyph representing the ligature. For example, if the input is a pair of regional indicator symbols, determine whether there is an emoji flag for the pair.
Finally, if the string contains a variation selector, the method only returns true if the fonts contains a glyph specific to that variation.
Checking is done on the entire fallback chain, not just the immediate font referenced.

Set the paint's style, used for controlling how primitives' geometries are interpreted (except for drawBitmap, which always assumes Fill).
|
Unit |
setSubpixelText(subpixelText: Boolean)
Helper for setFlags(), setting or clearing the SUBPIXEL_TEXT_FLAG bit
|
Unit |
setTextAlign(align: Paint.Align!)
Set the paint's text alignment. This controls how the text is positioned relative to its origin. LEFT align means that all of the text will be drawn to the right of its origin (i.e. the origin specifies the LEFT edge of the text) and so on.
|
Unit |
setTextLocale(locale: Locale)
Set the text locale list to a one-member list consisting of just the locale. See setTextLocales(android.os.LocaleList) for how the locale list affects the way the text is drawn for some languages.
|
Unit |
setTextLocales(locales: LocaleList)
Set the text locale list. The text locale list affects how the text is drawn for some languages. For example, if the locale list contains Locale.CHINESE or Locale.CHINA, then the text renderer will prefer to draw text using a Chinese font. Likewise, if the locale list contains Locale.JAPANESE or Locale.JAPAN, then the text renderer will prefer to draw text using a Japanese font. If the locale list contains both, the order those locales appear in the list is considered for deciding the font. This distinction is important because Chinese and Japanese text both use many of the same Unicode code points but their appearance is subtly different for each language. By default, the text locale list is initialized to a one-member list just containing the system locales. This assumes that the text to be rendered will most likely be in the user's preferred language. If the actual language or languages of the text is/are known, then they can be provided to the text renderer using this method. The text renderer may attempt to guess the language script based on the contents of the text to be drawn independent of the text locale here. Specifying the text locales just helps it do a better job in certain ambiguous cases.

Unit |
setTextScaleX(scaleX: Float)
Set the paint's horizontal scale factor for text. The default value is 1.0. Values > 1.0 will stretch the text wider. Values < 1.0 will stretch the text narrower.
|
Unit |
setTextSize(textSize: Float)
Set the paint's text size. This value must be > 0
|
Unit |
setTextSkewX(skewX: Float)
Set the paint's horizontal skew factor for text. The default value is 0. For approximating oblique text, use values around -0.25.
|
Typeface! |
setTypeface(typeface: Typeface!)
Set or clear the typeface object.
Pass null to clear any previous typeface. As a convenience, the parameter passed is also returned.
|
Unit |
setUnderlineText(underlineText: Boolean)
Helper for setFlags(), setting or clearing the UNDERLINE_TEXT_FLAG bit
|
Unit |
setWordSpacing(wordSpacing: Float)
Set the paint's extra word-spacing for text. Increases the white space width between words with the given amount of pixels. The default value is 0.
|
Xfermode! |
setXfermode(xfermode: Xfermode!)
Set or clear the transfer mode object. A transfer mode defines how source pixels (generate by a drawing command) are composited with the destination pixels (content of the render target).
Pass null to clear any previous transfer mode. As a convenience, the parameter passed is also returned.
PorterDuffXfermode is the most common transfer mode.
