Interface ImagePainter

All Known Implementing Classes:

BitmapPainter

public interface ImagePainter

A common interface for objects that can render ppt picture data.

Subclasses can redefine it and use third-party libraries for actual rendering, for example, Bitmaps can be rendered using javax.imageio.* , WMF can be rendered using Apache Batik, PICT can be rendered using Apple QuickTime API for Java, etc.

A typical usage is as follows: public WMFPaiter implements ImagePainter{ public void paint(Graphics2D graphics, PictureData pict, Picture parent){ DataInputStream is = new DataInputStream(new ByteArrayInputStream(pict.getData())); org.apache.batik.transcoder.wmf.tosvg.WMFRecordStore wmfStore = new org.apache.batik.transcoder.wmf.tosvg.WMFRecordStore(); try { wmfStore.read(is); } catch (IOException e){ return; } Rectangle anchor = parent.getAnchor(); float scale = (float)anchor.width/wmfStore.getWidthPixels(); org.apache.batik.transcoder.wmf.tosvg.WMFPainter painter = new org.apache.batik.transcoder.wmf.tosvg.WMFPainter(wmfStore, 0, 0, scale); graphics.translate(anchor.x, anchor.y); painter.paint(graphics); } } PictureData.setImagePainter(Picture.WMF, new WMFPaiter()); ... Subsequent calls of Slide.draw(Graphics gr) will use WMFPaiter for WMF images.
