flag: make the component fit in page width if needed

---

keepRatio

private boolean keepRatio

if component is resized; keep its ratio

---

Constructor Detail

PrintableComponent

public PrintableComponent(java.awt.Component component,
                          java.awt.print.PageFormat pf,
                          boolean autoFit)

---

PrintableComponent

public PrintableComponent(java.awt.Component component,
                          java.awt.print.PageFormat pf)

convenient constructor that take autofit value from preferences

Method Detail

print

public int print(java.awt.Graphics graphics,
                 java.awt.print.PageFormat pf,
                 int pageIndex)

throws PrinterExceptionPrints the page at the specified index into the specified Graphics context in the specified format. A PrinterJob calls the Printable interface to request that a page be rendered into the context specified by graphics. The format of the page to be drawn is specified by pageFormat. The zero based index of the requested page is specified by pageIndex. If the requested page does not exist then this method returns NO_SUCH_PAGE; otherwise PAGE_EXISTS is returned. The Graphics class or subclass implements the PrinterGraphics interface to provide additional information. If the Printable object aborts the print job then it throws a PrinterException. Parameters: graphics - the context into which the page is drawn pageFormat - the size and orientation of the page being drawn pageIndex - the zero based index of the page to be drawn Returns: PAGE_EXISTS if the page is rendered successfully or NO_SUCH_PAGE if pageIndex specifies a non-existent page. Throws: PrinterException - thrown when the print job is terminated.

Specified by:

print in interface java.awt.print.Printable

---

paintComponent

protected void paintComponent(java.awt.Graphics graph)

Invoked by Swing to draw components.

---

updateInternalData

private void updateInternalData()

update current number of pages and cache of original component image. compute new size of component (width, height) to fit the page. To call each time pageFormat or component changed.

---

getNumberOfPages

public int getNumberOfPages()

Returns the number of pages in the set. To enable advanced printing features, it is recommended that Pageable implementations return the true number of pages rather than the UNKNOWN_NUMBER_OF_PAGES constant.

Specified by:

getNumberOfPages in interface java.awt.print.Pageable

---

isOpaque

public boolean isOpaque()

Returns true if this component is completely opaque.

An opaque component paints every pixel within its rectangular bounds. A non-opaque component paints only a subset of its pixels or none at all, allowing the pixels underneath it to "show through". Therefore, a component that does not fully paint its pixels provides a degree of transparency.

Subclasses that guarantee to always completely paint their contents should override this method and return true.

---

getPageFormat

public java.awt.print.PageFormat getPageFormat(int pageIndex)
                                        throws java.lang.IndexOutOfBoundsException

Returns the PageFormat of the page specified by pageIndex.

Specified by:

getPageFormat in interface java.awt.print.Pageable

---

getPrintable

public java.awt.print.Printable getPrintable(int pageIndex)
                                      throws java.lang.IndexOutOfBoundsException

Returns the Printable instance responsible for rendering the page specified by pageIndex.

Specified by:

getPrintable in interface java.awt.print.Pageable

---

isAutoFit

public boolean isAutoFit()

Getter for property autoFit.

---

setAutoFit

public void setAutoFit(boolean autoFit)

public java.awt.Component getComponent()

Getter for property component.

---

public void setComponent(java.awt.Component component)

Setter for property component.

---
