Ok. I overcome this as programmatically. Below code helped me.
{code:java}
PDPageTree list = document.getPages();
int pageNumber = 1;
int imageId = 1;
for (PDPage page : list) {
PDResources pdResources = page.getResources();
for (COSName c : pdResources.getXObjectNames()) {
PDXObject o = pdResources.getXObject(c);
if (o instanceof
org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject) {
File file = new File("LOCAL_PATH" + pageNumber + "_" + imageId
+ ".png" );
ImageIO.write(((org.apache.pdfbox.pdmodel.graphics.image.PDImageXObject)o).getImage(),
"png", file);
imageId++;
}
}
pageNumber++;
}
{code}

> When we use this command:
> {noformat}
> java -jar pdfbox-app-2.y.z.jar ExtractImages [OPTIONS] <inputfile>
> {noformat}
> We get images. But how to we know page number of images?They are extracted

> May doing naming convention should be like this:
> fileName_pageNumber_imageNumber.jpg
