A small tool included with Free Pascal allows to use pascal for this task. It is a mature technology, and as such can be expected to have a well-established code base and a rich feature set. By contrast, Morfik is a relative young technology, and still has some way to go. In this article, the basics of Intraweb are explained, and at the same time a comparison with Morfik is made.
After one year and a half, the result of their efforts will is available for sale from several websites, and shipping is expected to start in March of this year.
For many people this will be the end of a long period of waiting, since Borland has actively tried to keep the developers' interest in Kylix high. Now, finally the time has come. What follows is an overview of what can be expected, based on experiences with some Beta releases also called Field Tests, in Borland Jargon.

Many aspects of such programs will be discussed; No code will be presented other than some small code snippets to illustrate the ideas.

Tj line uses the Tj operator to display the text in parentheses on the page. The final line inside the stream, 0 —12 TD, uses the TD operator to offset text from the current location.
In this case, the horizontal coordinate isn't modified 0. The —12 value moves text to the next line; actually it moves the text by FontSize toward the bottom of the page. To create page contents objects, the TPDFExport component uses the CreatePageContents method that is able to create both uncompressed and zlib compresssed streams. Compressing data in Delphi cannot be simpler. To compress a stream that contains uncompressed data, you have to use the TCompressionStream class declared in the ZLib unit.
The actual compression of data occurs when you copy data from an uncompressed stream to the compression stream. The constructor of the TCompressionStream class accepts two parameters: the level of compression and the destination stream where the compressed data will be written. The following excerpt shows how to compress a stream using the TCompressionStream class. CopyFrom buff, 0 ; finally C. Notice that the method has two out parameters which are only used to output values from the method to the outside world.
FirstObject returns the ID of the first page contents object and the ObjectCount parameter returns the number of page contents objects created.
These two values are later used by the method that creates page objects. Free; end; end; Creating the Page Tree and the Page Objects The page tree is a very important object that contains the number of pages available in the document the Count key and the references to all document pages the Kids array.
The page tree is used by viewer applications to quickly access any page in the document, no matter how many pages there are. Besides having to reference the page tree Parent object, a page object must have a MediaBox key that defines the page size, a Contents key that references the page contents object for the page, and a Resources key that references the resource dictionary.
To achieve this, the method has to accept the ID of the first page contents object and the number of page contents objects available in the document both values are returned by the CreatePageContents method.
The method must also return the ID of the page tree object because it's needed later. Listing shows the CreatePages method. In this case, the document catalog only needs to reference the page tree object.
