    public class PDFStyle
extends java.lang.Object
implements java.lang.Cloneable

    A PDFStyle controls the colors, font and many other aspects of the actual display of elements on a PDF page. It's conceptually similar to a CSS style used with HTML markup.

    The idea behind the PDFStyle class is that you create a style and then apply it to the PDFPage. This means you can switch from one style to another with a single command, and switch back just as easily. It makes defining a consistant "feel" to your document much easier than it would if you had to set the font and color separately.

    Example 
       import java.awt.Color;

   // Create a new style "normal": 12pt black Times-Roman, with
   // line-spacing of 1.5
   PDFStyle normal = new PDFStyle();
   normal.setFont(new StandardFont(StandardFont.TIMES), 12);
   normal.setFillColor(Color.black);
   normal.setTextLineSpacing(1.5);

   // Create a new varient of "normal": 12pt red Times-Italic with
   // the same line-spacing
   PDFStyle italic = new PDFStyle(normal);
   italic.setFont(new StandardFont(StandardFont.TIMESITALIC), 12);
   italic.setFillColor(Color.red);

   // Create a style to draw a box around the text in green, with a
   // line width of 2 points
   PDFStyle boxstyle = new PDFStyle();
   boxstyle.setLineColor(Color.green);
   boxstyle.setLineWeighting(2);

   // Now use these styles in a document
   PDF p = new PDF();
   PDFPage page = p.newPage(PDF.PAGESIZE_A4);
   page.setStyle(normal);
   page.drawText("This is in 12pt black Times Roman", 100, 100);
   page.setStyle(italic);
   page.drawText("This is in 12pt red Times Italic", 100, 120);

   // Draw a box around them in green
   page.setStyle(boxstyle);
   page.drawRectangle(90,90, 200, 40);

    This shows several useful aspects of styles:

    • Styles can easily be extended by using the PDFStyle(PDFStyle) constructor
    • Not all the aspects of a style need to be set
    • Styles can be given meaningful names

      • setFillColor

        public void setFillColor​(java.awt.Paint paint)

        Set the fill color. For text, this is the color of the text. For geometric shapes, this is paint to fill those shapes with. To draw only outlines, set it to null (the default).

        Prior to release 1.2, this method took a Color as an argument, but this has been changed to its superclass Paint instead. Although most of the time the parameter will still be a plain color, this change allows a GradientPaint to be used as well.

        Parameters:
        paint - the paint to use, or null if no fill is required.
        Since:
        1.0

      • setLineColor

        public void setLineColor​(java.awt.Paint paint)
        Set the line color. For text, this is the color of the outline of the text. For geometric shapes, this is color to draw the outlines of those shapes. If no outline is required, set it to null (the default).
        Parameters:
        paint - the Color to use, or null if no outline is required.
        Since:
        1.0

      • setLineWeighting

        public void setLineWeighting​(float weight)
        Set the line weighting, for fonts and geometric shapes drawn as outlines. The minimum possible value is zero, which indicates to the PDF renderer to use the thinest line possible. On high-resolution devices this will become nearly invisible, and because of its device-dependent nature a value of 0 is not recommended.

        Changes to this setting midway through a path don't take effect until the path is closed.

        Parameters:
        weight - the thickness of the line in points, or 0 for "as thin as possible"
        Since:
        1.0

      • setLineDash

        public void setLineDash​(float on,
                        float off,
                        float phase)

        Set the line dashing pattern. Since 2.7.8 this method simply calls setLineDash(new float[] { on, off }, phase).

        Parameters:
        on - how many points of the line to draw
        off - how many points of the line to skip
        phase - how far into the pattern to start
        Since:
        1.0

      • setLineDash

        public void setLineDash​(float[] pattern,
                        float phase)

        Set the line dashing pattern. The pattern parameter is an array of 1 or more float values that are > 0, which define the length in points of the alternating "on" and "off" segments of any lines drawn with this style. The phase paramter determines how far into this pattern to start.

        To draw solid lines, the first parameter should be null.

        Changes to this setting midway through a path don't take effect until the path is closed.

        Parameters:
        pattern - the pattern of alternating on/off segments, or null to draw solid lines
        phase - how far into the pattern to start
        Since:
        2.7.8

      • setFontFeature

        public void setFontFeature​(java.lang.String feature,
                           boolean on)
        Set the specified font feature. This method takes the same parameters as the PDFFont.setFeature(String,boolean) method, but the features will be only be applied to the font for text created with this style.
        Since:
        2.14.1

      • setFontFeature

        public void setFontFeature​(java.lang.String feature,
                           int value)
        Set the specified font feature. This method takes the same parameters as the PDFFont.setFeature(String,int) method, but the features will be only be applied to the font for text created with this style.
        Since:
        2.22

      • getOpenTypeFontPalette

        public OpenTypeFont.Palette getOpenTypeFontPalette()
        Get the OpenTypeFont.Palette previously specified with #setOpenTypeFontPalette
        Since:
        2.24.1

      • setOpenTypeFontPalette

        public void setOpenTypeFontPalette​(OpenTypeFont.Palette palette)
        If the font being used with this Style is an OpenTypeFont which has one or more color palettes, set the Palette to use. Any text created with that font will use the specified palette, provided the "color" feature is also set. Note it is possible to set a custom palette not retrieved from the font, provided it has the correct number of entries. If no palette is specified, the first palette from the font will be used (this is the default).
        Parameters:
        palette - the color palette to use when rendering the font
        Since:
        2.24.1

      • setTextLineSpacing

        public void setTextLineSpacing​(float spacing)

        Set the spacing between lines of text. The paramater is a multiple of the default spacing between lines for this font (as determined by the PDFFont.getDefaultLeading() method). This allows individual fonts to set their preferred line spacing more accurately.

        The default value is 1, for single-spaced text. A value of 1.5 sets line-and-a-half spacing, a value of 2 gives double spacing, and so on.

        Parameters:
        spacing - the spacing between lines
        Since:
        1.0

      • setTextIndent

        public void setTextIndent​(float indent)

        Set the number of points to indent the first line of any text drawn in this style. Positive values result in the first line being indented to the right, negative values in the first line being indented to the left (this is reversed for RTL scripts)

        Note that mixing styles with different text-indent levels on the first line of text in a paragraph will result in unpredictable results.

        Since:
        1.1.21

      • setTextJustificationRatio

        public void setTextJustificationRatio​(float i)
        Set the text justification ratio for a style. When a line of text is padded to justify it against two margins, there is always the the option of extending the space between each character, extending the space between each word, or a combination of the two. The "justification ratio" determines how much to apply to each. A ratio of 0 means "only extend the spaces between words", a ratio of 1 means "only extend the spaces between letters". The default is 0.5.
        Since:
        1.0

      • setOverprint

        public void setOverprint​(boolean on)
        Cause text and objects drawn with this style to overprint. Has no effect unless the fill and/or line color are CMYK or Spot colors. The default is false.
        Since:
        2.10

      • setTextUnderline

        public void setTextUnderline​(boolean on)
        Set whether text rendered with this style is underlined or not. The exact position and width of the underlining is font specific. The default is false.
        Since:
        1.1

      • setTextDoubleUnderline

        public void setTextDoubleUnderline​(boolean on)
        Set whether text rendered with this style is double-underlined or not. The exact position and width of the underlining is font specific. The default is false.
        Since:
        2.11.12

      • setTextStrikeOut

        public void setTextStrikeOut​(boolean on)
        Set whether text rendered with this style is struck-out or not. The default is false.
        Since:
        1.1

      • setTextSmallCaps

        public void setTextSmallCaps​(boolean on)
        Set whether text in this style is displayed with "small-caps" - ie. all lower case letters are displayed as upper-case but at 80% of the original font-size. The default is false. Since 2.22 this is identical to setFontFeature("smallcaps")
        Since:
        2.5

      • setTrackKerning

        public void setTrackKerning​(float kern)

        Allows you to explicitly set the kerning between characters for a font. This method may be called as many times as necessary - between each character if required - to set the kerning distance between characters for all future text rendered in this style ("characters" in this context includes spaces). This "track kerning" is used as well as the standard "pair-wise" kerning, as returned by PDFFont.getKerning(char, char).

        If text-alignment is set to TEXTALIGN_JUSTIFY, kerning (both track and pairwise) is scaled up or down depending on the justification required.

        Parameters:
        kern - the space to place between each character in millipoints (thousandths of a point) if this font was rendered one point high. May be positive, which moves the characters apart, or negative to move them closer together.
        Since:
        1.1.14
        See Also:
        PDFFont.getKerning(char, char)

      • setTextRise

        public void setTextRise​(float offset)

        Set the text vertical offset - the distance between the standard baseline and the basline for this style, as a proportion of the font size. This is mainly used for superscripting or subscripting. text.

        As an example, if you wanted to create a line of text that was 6 points high and 6 points above the standard baseline, set the font size to 6 and the TextRise() to 1. (1x6 = 6 points above the baseline). To place the same text 3 points below the baseline, set the offset to -0.5.

        Since:
        1.1

      • addBackupFont

        public void addBackupFont​(PDFFont font)
        Add a backup font to the current style. Backup fonts are used when the standard font doesn't have a character defined - for example, creating a style with the "Times Roman" font and then adding a backup font of "Symbol" would allow text to be written in both English and Greek without changing styles. As many backup fonts as are required may be added.
        Parameters:
        font - the font to add as a backup for the current style.
        Since:
        1.2

      • setPaintMethod

        public void setPaintMethod​(int method)

        Set the paint method to either PAINTMETHOD_EVENODD or PAINTMETHOD_NONZEROWINDING (the default). The paint method determines which area of a self-intersecting polygon is filled. If your polygons aren't self-intersecting, it has no effect.

        This setting is very obscure and is really only here for completeness. For a full discussion of the difference see the PDF Reference manual version 1.4, page 169.

        Since:
        1.1.5

      • setLineCap

        public void setLineCap​(int cap)

        Changes to this setting midway through a path don't take effect until the path is closed.

        This setting is very obscure and is really only here for completeness. For a full discussion of the difference see the PDF Reference manual version 1.4, page 153.
        Parameters:

        Deprecated.
        call createGlyphVector(java.lang.String, java.util.Locale) and retrieve this information from there
        As getTextLength() but sets the width of each character in the specified arrays; a very low level routine unlikely to be used by many, but useful for calculating break points for advanced layout engines like the Report Generator.
        Parameters:
        buf - the character buffer to use
        off - the offset into that buffer to start at
        len - the number of characters to process
        widths - if not null, an array len long which will be populated with the width of each character in points
        kerns - If not null, an array len long which will be populated with the kerning values after each character, in points. Negative values move the next character closer, positive moves them further away.

        Returns a PDFGlyphVector containing the glyph codes for the specified text in this style. This can then be drawn directly to a PDFCanvas. See the PDFGlyphVector class for an example.

        Note that the returned PDFGlyphVector may not represent the complete String: the returned item will contain as many characters as can be displayed in this font, which may be the same as text.length(), or empty if none of the characters are available in the font. See PDFGlyphVector.getTextLength() to determine how many characters were consumed.

        Parameters:
        text - the text to display
        text - the offset to add to any indices into that text, as returned by PDFGlyphVector.getFirstIndex(int) (0 if in doubt)
        locale - the locale of the text, or null to use the default
        level - the level in the Unicode bidirectional algorithm for this glyph vector, or 0 if it doesn't apply.
