If this feature is not supported, at least, can I place a transparent image on the export PDF and then later on using itext library or others, be able to find out that image and replace it with something else?
You may use the special k-pdf-export CSS selector in combination with a selector for the corresponding image to make that image visible for the ClientExportManager when exporting. You may hide it initially with display none and change its display to block with this selector. Thus, the image will be visible for the export only.
What I am after is that, I want to embed maybe a text/image, then when I load the PDF using itext library to parse the PDF, I want to detect that placeholder inside the PDF.
