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.

when we run this from command line,
* if we set -Xms=512m and -Xmx=512m, its complaining after 12 pages.
* if we set -Xms=1024m and -Xmx=1024m, its complaining after 27 pages.
On the side, we are also getting "Colour key masking isn't supported" message
for each image in the file.
