after some debug i can add tho information ...
the images with a null ref use this kind of ImageRenderInfo constructor:
private ImageRenderInfo(Matrix ctm, InlineImageInfo inlineImageInfo,
PdfDictionary colorSpaceDictionary) {
this.ctm = ctm;
this.ref = null;
this.inlineImageInfo = inlineImageInfo;
this.colorSpaceDictionary = colorSpaceDictionary;
}
as i can see doesn't exist ref ... it is set to null
and after a little bit of debug i fond this piece of code that call thie
constructor
if ("BI".equals(operator.toString())){
// we don't call invokeOperator for embedded images - this is one area of
the PDF spec that is particularly nasty and inconsistent
PdfDictionary colorSpaceDic = resources != null ?
resources.getAsDict(PdfName.COLORSPACE) : null;
handleInlineImage(InlineImageUtils.parseInlineImage(ps,
colorSpaceDic), colorSpaceDic);
} else {
invokeOperator(operator, operands);
}
so ... embedded image has no reference ...
after this my answer change a little bit, is there a way to retrive an image
Object directly.. like :
PdfObject pdfobj = reader.getPdfObject(index i) ... if i don't have a ref
i use Itext 5.5.1
