Matching an image to its placement


I’m trying to match an image in a page of a PDF file (in Page.Resources.Images) with its placement (using an ImagePlacementAbsorber).
I’m using Aspose PDF 8.1

Using the ImagePlacementAbsorber I can get the position of each image in a particular page and it also has a reference to an XImage object.
The problem is that I can’t map that XImage object to the one in Page.Resources.Images because I don’t know it’s name or index.
The XImage object that’s in the ImagePlacement object always has its name set to “X”.

How can I find the image at Page.Resources.Images that matches a particular ImagePlacement instance?

Hi Tilal,

Apologies for the delay.
Attached you will find a document that describes the issue. It’s a one-page PDF document with three images that was saved from Microsoft Word 2010 (using Save As action)

This is some sample code I used to describe the problem.

Document doc = new Document(“path_to_file”);
ImagePlacementAbsorber absorber = new ImagePlacementAbsorber();
Page page1 = doc.Pages[1];
for (int i = absorber.ImagePlacements.Count; i > 0; i–){
ImagePlacement imgPlc = absorber.ImagePlacements[i];
Console.WriteLine("Placement Image Name: " + (imgPlc.Image.Name??“null”));
XImageCollection pageImages = page1.Resources.Images;
var enumerator = pageImages.GetEnumerator();
while (enumerator.MoveNext())
XImage img = (XImage)enumerator.Current;
Console.WriteLine("Resource Image Name: " + (img.Name??"null);

Note that in both the XImage object in the page resource’s and the one in the ImagePlacement the “Name” is always null.
This is the output from the code above:
Placement Image Name: null
Placement Image Name: null
Placement Image Name: null
Resource Image Name: null
Resource Image Name: null
Resource Image Name: null
