HwmfGraphics

public HwmfGraphics(java.awt.Graphics2D graphicsCtx,
                    java.awt.geom.Rectangle2D bbox)

Initialize a graphics context for wmf rendering

Parameters:

graphicsCtx - the graphics context to delegate drawing calls

bbox - the bounding box of the wmf (taken from the placeable header)

getProperties

public HwmfDrawProperties getProperties()

draw

getStroke

protected java.awt.BasicStroke getStroke()

getFill

protected java.awt.Paint getFill()

getSolidFill

getHatchedFill

protected java.awt.Paint getHatchedFill()

getPatternPaint

protected java.awt.Paint getPatternPaint()

addObjectTableEntry

public void addObjectTableEntry(HwmfObjectTableEntry entry)

Adds an record of type HwmfObjectTableEntry to the object table. Every object is assigned the lowest available index-that is, the smallest numerical value-in the WMF Object Table. This binding happens at object creation, not when the object is used. Moreover, each object table index uniquely refers to an object. Indexes in the WMF Object Table always start at 0.

Parameters:

entry -

applyObjectTableEntry

public void applyObjectTableEntry(int index)

Applies the object table entry

Parameters:

index - the index of the object table entry (0-based)

Throws:

java.lang.IndexOutOfBoundsException - if the index is out of range

java.util.NoSuchElementException - if the entry was deleted before

unsetObjectTableEntry

public void unsetObjectTableEntry(int index)

Unsets (deletes) the object table entry for further usage When a META_DELETEOBJECT record (section 2.3.4.7) is received that specifies this object's particular index, the object's resources are released, the binding to its WMF Object Table index is ended, and the index value is returned to the pool of available indexes. The index will be reused, if needed, by a subsequent object created by another Object Record Type record.

Parameters:

index - the index (0-based)

Throws:

java.lang.IndexOutOfBoundsException - if the index is out of range

saveProperties

public void saveProperties()

Saves the current properties to the stack

restoreProperties

public void restoreProperties(int index)

Restores the properties from the stack

Parameters:

index - if the index is positive, the n-th element from the start is activated. If the index is negative, the n-th previous element relative to the current properties element is activated.

updateWindowMapMode

public void updateWindowMapMode()

After setting various window and viewport related properties, the underlying graphics context needs to be adapted. This methods gathers and sets the corresponding graphics transformations.
