示例1: fillBeadRectangles
import org.apache.pdfbox.pdmodel.PDPage; //导入方法依赖的package包/类
private void fillBeadRectangles(PDPage page)
{
beadRectangles = new ArrayList<PDRectangle>();
for (PDThreadBead bead : page.getThreadBeads())
{
if (bead == null)
{
// can't skip, because of null entry handling in processTextPosition()
beadRectangles.add(null);
continue;
}
PDRectangle rect = bead.getRectangle();
// bead rectangle is in PDF coordinates (y=0 is bottom),
// glyphs are in image coordinates (y=0 is top),
// so we must flip
PDRectangle mediaBox = page.findMediaBox();
float upperRightY = mediaBox.getUpperRightY() - rect.getLowerLeftY();
float lowerLeftY = mediaBox.getUpperRightY() - rect.getUpperRightY();
rect.setLowerLeftY(lowerLeftY);
rect.setUpperRightY(upperRightY);
// adjust for cropbox
PDRectangle cropBox = page.findCropBox();
if (cropBox.getLowerLeftX() != 0 || cropBox.getLowerLeftY() != 0)
{
rect.setLowerLeftX(rect.getLowerLeftX() - cropBox.getLowerLeftX());
rect.setLowerLeftY(rect.getLowerLeftY() - cropBox.getLowerLeftY());
rect.setUpperRightX(rect.getUpperRightX() - cropBox.getLowerLeftX());
rect.setUpperRightY(rect.getUpperRightY() - cropBox.getLowerLeftY());
}
beadRectangles.add(rect);
}
