----------------------------------------------------------
Thanks for your prompt reply.
* We are programmatically extracting the image (using the same steps) - thats
why we are not using ExtractImages which is pretty much a command line utility.
* No we have not - we will give it a go and let you know.
* Only this PDF - generally it works fine.
* In this case, it looks like tiff files.
* Will check with the management team and let you know since the issue occurred
in production and we are not sure if our SLA allows giving the actual PDF.

> We are trying to extract images from PDF file. As part of that, we are
> converting a PDPage into an image. using PDPage.convertImage method. Its a 52
> page document.
> At that time, We are seeing the following trace:
> Here are the steps:
> PDDocument document = PDDocument.load(inputStream);
> List<PDPage> pages = document.getDocumentCatalog().getAllPages();
> for (PDPage pdPage : pages) {
> if (pdPage.getResources() != null && pdPage.getResources().getImages() !=
> null)
> PageInfo page = new PageInfo(pdPage, true, rotation);
> ...
> }
> }
> In PageInfo, we are doing:
> BufferedImage bimage = page.convertToImage();
> And after processing about 12 or so pages, it starts complaining as follows.
