示例1: insertBgImg
import org.fit.cssbox.layout.BackgroundImage; //导入依赖的package包/类
/**
* Draws element background image to OUTPUT
*/
private void insertBgImg (ElementBox elem, int i, float plusOffset, float plusHeight) {
for (BackgroundImage bimg : elem.getBackgroundImages()) {
BufferedImage img = bimg.getBufferedImage();
float pageStart = i*pageFormat.getHeight();
float pageEnd = (i+1)*pageFormat.getHeight();
if (img != null && elem.getAbsoluteContentY()*resCoef+plusOffset < pageEnd && (elem.getAbsoluteContentY()+img.getHeight())*resCoef+plusOffset+plusHeight > pageStart) {
// calculates resized coordinates in CSSBox form
float startX = (elem.getAbsoluteContentX()-elem.getPadding().left)*resCoef;
float startY = (elem.getAbsoluteContentY()-elem.getPadding().top)*resCoef+plusOffset-i*pageFormat.getHeight();
float width = img.getWidth()*resCoef;
float height = img.getHeight()*resCoef;
// correction of long backgrounds
if (height > 5*plusHeight) height += plusHeight;
// inserts image
insertImagePDFBox(img, startX, startY, width, height);
