                        Dimension dim,
                        URL baseurl)

Creates a canvas from a PDF file and computes the layout.

Parameters:

document - the PDF document

decoder - DOM analyzer

dim - preferred canvas dimension

baseurl - base URL for loading referenced data

PdfBrowserCanvas

public PdfBrowserCanvas(org.apache.pdfbox.pdmodel.PDDocument document,
                        int startPage,
                        int endPage,
