Class PDFThumbnailer

java.lang.Object

co.elastic.thumbnails4j.pdf.PDFThumbnailer

All Implemented Interfaces:

Thumbnailer

public class PDFThumbnailer
extends Object
implements Thumbnailer

A Thumbnailer for Portable Document Formatted (PDF) documents. These documents will often have a .pdf file extension. PDFThumbnailer attempts to find the first image in the format that actually fits on a page, and returns that scaled image. This can be confusing if you attempt to thumbnail a poorly built PDF whose first page has a background image that is larger than the size of the PDF's first page. However, this approach avoids Memory issues that can occur when attempting to read undisplayably-large images.
