static TextBlock | createTextBlock(String text, Font font, Paint paint)
Creates a TextBlock from a String . |
static TextBlock | createTextBlock(String text, Font font, Paint paint, float maxWidth, TextMeasurer measurer)
Creates a new text block from the given string, breaking the
text into lines so that the maxWidth value is
respected.

static Rectangle2D | getTextBounds(String text, Graphics2D g2, FontMetrics fm)
Returns the bounds for the specified text.
|
static boolean | getUseFontMetricsGetStringBounds()
Returns the flag that controls whether the FontMetrics.getStringBounds()
method is used or not. |
static boolean | isUseDrawRotatedStringWorkaround() |
static void | setUseDrawRotatedStringWorkaround(boolean use)
Sets the flag that controls whether or not a workaround is used for
drawing rotated strings. |
static void | setUseFontMetricsGetStringBounds(boolean use)
Sets the flag that controls whether the FontMetrics.getStringBounds()
method is used or not. |
Parameters: text the text (null
permitted). g2 the graphics device. x the x coordinate for the anchor point. y the y coordinate for the anchor point. textAnchor the text anchor. angle the angle. rotationAnchor the rotation anchor.
Returns: The bounds (possibly null
).
Parameters: text the text (null
permitted). g2 the graphics device. textX the x coordinate for the text. textY the y coordinate for the text. angle the angle. rotateX the x coordinate for the rotation point. rotateY the y coordinate for the rotation point.
Returns: The bounds (null
if text
is
null or has zero length).
String
. Line breaks
are added where the String
contains '\n' characters.
Parameters: text the text. font the font. paint the paint.
Returns: A text block.
maxWidth
value is
respected.
Parameters: text the text. font the font. paint the paint. maxWidth the maximum width for each line. measurer the text measurer.
Returns: A text block.
maxWidth
value is
respected.
Parameters: text the text. font the font. paint the paint. maxWidth the maximum width for each line. maxLines the maximum number of lines. measurer the text measurer.
Returns: A text block.
Parameters: text the text. g2 the graphics device. x the x coordinate (Java 2D). y the y coordinate (Java 2D). anchor the anchor location.
Returns: The text bounds (adjusted for the text position).
A common rotation is -Math.PI/2 which draws text 'vertically' (with the top of the characters on the left).
Parameters: text the text. g2 the graphics device. angle the angle of the (clockwise) rotation (in radians). x the x-coordinate. y the y-coordinate.
A common rotation is -Math.PI/2 which draws text 'vertically' (with the top of the characters on the left).
Parameters: text the text. g2 the graphics device. textX the x-coordinate for the text (before rotation). textY the y-coordinate for the text (before rotation). angle the angle of the (clockwise) rotation (in radians). rotateX the point about which the text is rotated. rotateY the point about which the text is rotated.
Parameters: text the text. g2 the graphics device. x the x-coordinate for positioning the text. y the y-coordinate for positioning the text. textAnchor the text anchor. angle the rotation angle. rotationX the x-coordinate for the rotation anchor point. rotationY the y-coordinate for the rotation anchor point.
Parameters: text the text. g2 the graphics device. x the x-coordinate for positioning the text. y the y-coordinate for positioning the text. textAnchor the text anchor. angle the rotation angle (in radians). rotationAnchor the rotation anchor.
Parameters: text the text (null
permitted). g2 the graphics context (not null
). fm the font metrics (not null
).
Returns: The text bounds (null
if the text
argument is null
).
Returns: A boolean.
TextLayout
instance to draw the text instead of calling the
drawString()
method in the Graphics2D
class.
Parameters: use the new flag value.
Parameters: use the flag.
