Class DropCapSpan

java.lang.Object
  danger.text.span.DropCapSpan

All Implemented Interfaces:

LeftMarginSpan, LineHeightSpan, MetricAffectingSpan, ParagraphSpan

public class DropCapSpan
extends Object
implements LeftMarginSpan, LineHeightSpan

DropCapSpan is a LeftMarginSpan that draws a specified bitmap in front of as much of the paragraph as the bitmap is tall, and then lets the margin width go back to 0. If the bitmap is taller than the paragraph, the last line of the paragraph will be stretched to be as tall as is necessary to complete the bitmap.

Constructor Summary

DropCapSpan(Bitmap b)
Create a new drop cap with the specified bitmap.

Method Summary

int	drawLeftMargin(Pen p, int x, int top, int baseline, int bottom, Object[] spans, CharSequence text, int parStart, int lineStart, int paragraphDistance, Object[] cspans) If this line of the paragraph is close enough to the top that it is next to the bitmap, the appropriate section of the bitmap is drawn in the left margin.
int	getVerticalDimensions(Font f, CharSequence text, int parStart, int lineStart, int lineEnd, Object[] rulers, int ascent, int descent, int pd) If this is the last line of the paragraph and the height of the line is still not enough that the bitmap will be done by the bottom of it, the line is stretched tall enough to complete the bitmap.
int	modifyLeftMargin(int margin, Object[] spans, Font f, CharSequence text, int parStart, int lineStart, int paragraphDistance) If this line of the paragraph is close enough to the top that it is next to the bitmap, the left margin is as wide as the bitmap.

Method Detail

modifyLeftMargin

public int modifyLeftMargin(int margin,
                            Object[] spans,
                            Font f,
                            CharSequence text,
                            int parStart,
                            int lineStart,
                            int paragraphDistance)

If this line of the paragraph is close enough to the top that it is next to the bitmap, the left margin is as wide as the bitmap.

drawLeftMargin

public int drawLeftMargin(Pen p,
                          int x,
                          int top,
                          int baseline,
                          int bottom,

                          int paragraphDistance,
                          Object[] cspans)

If this line of the paragraph is close enough to the top that it is next to the bitmap, the appropriate section of the bitmap is drawn in the left margin.

getVerticalDimensions

public int getVerticalDimensions(Font f,
                                 CharSequence text,
                                 int parStart,
                                 int lineStart,
                                 int lineEnd,
                                 Object[] rulers,
                                 int ascent,
                                 int descent,
                                 int pd)

If this is the last line of the paragraph and the height of the line is still not enough that the bitmap will be done by the bottom of it, the line is stretched tall enough to complete the bitmap.
