Class AlignmentContext

java.lang.Object
org.apache.fop.layoutmgr.inline.AlignmentContext
All Implemented Interfaces:
Constants
public class AlignmentContext extends Object implements Constants
The alignment context is carried within a LayoutContext and as part of the Knuth Inline elements to facilitate proper line building. All measurements are in mpt.

  • Method Details

    • getAlignmentPoint

      public int getAlignmentPoint()
      Returns the alignment point for this context. This is the point on the start edge of the area this context applies to measured from the before edge of the area.
      Returns:
      the default alignment point

    • getBaselineShiftValue

      public int getBaselineShiftValue()
      Returns the current value of baseline shift in effect.
      Returns:
      the baseline shift

    • getAlignmentBaselineIdentifier

      public int getAlignmentBaselineIdentifier()
      Returns the current alignment baseline identifier.
      Returns:
      the alignment baseline identifier

    • getDominantBaselineIdentifier

      public int getDominantBaselineIdentifier()
      Return the dominant baseline identifier.
      Returns:
      the dominant baseline identifier

    • getParentAlignmentContext

      public AlignmentContext getParentAlignmentContext()
      Return the parent alignment context.
      Returns:
      the parent alignment context

    • getTotalAlignmentBaselineOffset

      public int getTotalAlignmentBaselineOffset()
      Return the offset between the alignment baseline and the outermost parent dominant baseline.
      Returns:
      the offset in shift direction

    • getHeight

      public int getHeight()
      Return the total height of the context.
      Returns:
      the height

    • getAltitude

      public int getAltitude()
      The altitude of the context that is the height above the alignment point.
      Returns:
      the altitude

    • getDepth

      public int getDepth()
      The depth of the context that is the height below alignment point.
      Returns:
      the altitude

    • resizeLine

      public void resizeLine(int newLineHeight, int newAlignmentPoint)
      Resizes the line as specified. Assumes that the new alignment point is on the dominant baseline, that is this function should be called for line areas only.
      Parameters:
      newLineHeight - the new height of the line
      newAlignmentPoint - the new alignment point

    • getOffset

      public int getOffset()
      Returns the offset from the before-edge of the parent to this context.
      Returns:
      the offset for rendering

    • usesInitialBaselineTable

      public boolean usesInitialBaselineTable()
      Returns an indication if we still use the initial baseline table. The initial baseline table is the table generated by the Line LM.
      Returns:
      true if this is still the initial baseline table

    • toString

      public String toString()
      Overrides:
      toString in class Object
