[iText-questions] bug fix WMF as watermark ?

[Gerald Fehringer]

Hello iText users!   I tried to use a WMF as watermark which gave problems. Below you will a find modified version of the PdfContentByte.addImage() method which now allows to have a WMF as watermark (but I'm not satisfied with that bug fix since it would always create a new instance of an image and not reusing it):    /**   * Adds an <CODE>Image</CODE> to the page. The positioning of the <CODE>Image</CODE>   * is done with the transformation matrix. To position an <CODE>image</CODE> at (x,y)   * use addImage(image, image_width, 0, 0, image_height, x, y).   * @param image the <CODE>Image</CODE> object   * @param a an element of the transformation matrix   * @param b an element of the transformation matrix   * @param c an element of the transformation matrix   * @param d an element of the transformation matrix   * @param e an element of the transformation matrix   * @param f an element of the transformation matrix   * @throws DocumentException on error   */  public void addImage(Image image, float a, float b, float c, float d, float e, float f) throws DocumentException {   try {        if (image.isImgTemplate()) {     if( image instanceof com.lowagie.text.Watermark )     {      image = new com.lowagie.text.ImgWMF(image.url());     }     writer.addDirectImageSimple(image);     PdfTemplate template = image.templateData();     float w = template.getWidth();     float h = template.getHeight();     addTemplate(template, a / w, b / w, c / h, d / h, e, f);    }    else {     PdfName name;     PageResources prs = getPageResources();     Image maskImage = image.getImageMask();     if (maskImage != null) {      name = writer.addDirectImageSimple(maskImage);      prs.addXObject(name, writer.getImageReference(name));     }     name = writer.addDirectImageSimple(image);     name = prs.addXObject(name, writer.getImageReference(name));     content.append("q ");     content.append(a).append(' ');     content.append(b).append(' ');     content.append(c).append(' ');     content.append(d).append(' ');     content.append(e).append(' ');     content.append(f).append(" cm ");     content.append(name.toPdf(null)).append(" Do Q").append_i(separator);    }   }   catch (Exception ee) {    throw new DocumentException(ee.getMessage());   }  }   Kind regards, Gerald.
