To define the click-sensitive area and the destination URI. The point x, y is the bottom left corner of the rectangle containing hotspot rectangle, w, h are the width and height of the hotspot rectangle. The Border describes the thickness of the border surrounding the rectangle hotspot. Prepare an XObject image using the given arguments. This image will be added to the document if it is referenced at least once before the close method is called. Usage of interlaced GIFs are slower because they are decompressed, modified and compressed again.
The gif support is limited to images with a LZW minimum code size of 8.
Small images with few colors can have a smaller minimum code size and will not work. Try resaving the JPEG file with different compression options for example, disable progressive compression. It returns a big string.
You need to call close first. Unless using a filehandle, PDF:: Create assembles the entire PDF in memory.
If you create very large documents on a machine with a small amount of memory your program can fail because it runs out of memory. If using a filehandle, data will be written immediately to the filehandle after each method. Some gif images get created with a minimal lzw code size of less than 8. Create can not decode those and they must be converted.
I support PDF:: Create in my spare time between work and family, so the amount of work I put in is limited. If you experience a problem make sure you are at the latest version first many of things have already been fixed. Please register bug at the CPAN bug tracking system at http: I appreciate patches against the latest released version of PDF:: Create which fix the bug.
Feature request can be submitted like bugs. If you provide patch for a feature which does not go against the PDF:: Create philosophy keep it simple then you have a good chance for it to be accepted.

Page for details of methods available on a page: The parameter keys to the constructor are detailed as below: If neither filename or fh are specified, the content will be stored in memory and returned when calling close. See comment above regarding close. Version PDF Version to claim, can be 1. PageMode How the document should appear when opened.
Creator If the document was converted into a PDF document from another form, this is the name of the application that created the document. Title The title of the document. Subject The subject of the document. Therefore the CombinePDFs package is not object oriented, either.
A user of this package could create several instances, but all instances work on the same PDF file. Submitting complex data structures via the command line is a difficult issue, so I decided that bookmarks should come from a text file.
Children of the root bookmarks have a level of 1, their children a level of 2, and so on. Bookmarks are an array of hashes. Here it is the page number to open. During the loop over the file content, the code searches for each level the last entry in a variable and pushes its related children on those last entries.
The root bookmarks get collected as an array, and the loop adds the children as a reference to an array, and so on for the grand children.
Because I put a layer between the PDF::Reuse package and the command line application with the CombinePDFs package, it was easy to reuse those parts in the Tk-application app-combine-tk-pdfs. With the Tk application, the user visually selects PDF files, orders the files in a Tk::Tree widget, and changes the page ranges and the bookmarks text in Tk::Entry fields.
Furthermore, the application can store the resulting tree structure inside a session file and restored that later on. The Tk application can be found in the download at the end of this article. Beside the final PDF file, the application creates a file with the same basename and the.
This file contains the bookmarks for the PDF. When loading a bookmarks file, the same extension convention is in place. It is the package of choice if creating new PDF documents from scratch. However, it can work on multiple files at the same time. Use it if you need more features than PDF::Reuse actually provides. Return the newly created outline. Destination The Destination of this outline item.
In this version,it is only possible to give a page as destination. The default destination is the current page. Parent The parent of this outline in the outlines tree. This is an outline object. This way you represent the tree of your outlines.
Possible values are a0-a6, a4l,letter,broadsheet,ledger,tabloid,legal,executive and 36x Default is a4. Valid version numbers are 1. You must call close after you have added all the contents as most of the real work building the PDF is performed there. If omit calling close you get no PDF output.
Returns the raw content of the PDF. If fh was provided when creating object of PDF::Create then it does not try to close the file handle. It is, therefore, advised you call flush rather than close. URI links have two components,the text or graphics object and the area where the mouseclick should occur. For the object to be clicked on you'll use standard text of drawing methods.
