APACHE FOP AFP TO PDF

The renderers do not all have the same set of capabilities, sometimes because of the output format itself, sometimes because some renderers get more development attention than others. This can result in several differences, including actually using different fonts, and having different font metrics for the same font. The net effect is that the layout of a given FO document can be quite different between renderers that do not use the same font information. If FOP used the font metrics from its own font subsystem but still used Java2D for text painting in the Java2D-based renderers, this could probably be achieved. However, this approach hasn't been implemented, yet. The clue is to use the intermediate format.

The renderers do not all have the same set of capabilities, sometimes because of the output format itself, sometimes because some renderers get more development attention than others. This can result in several differences, including actually using different fonts, and having different font metrics for the same font.

The net effect is that the layout of a given FO document can be quite different between renderers that do not use the same font information.

If FOP used the font metrics from its own font subsystem but still used Java2D for text painting in the Java2D-based renderers, this could probably be achieved. However, this approach hasn't been implemented, yet. The clue is to use the intermediate format. The trick is to layout the document using FOP's own font subsystem but then render the document using Java2D. Here are the necessary steps using the command-line :. Note that no PDF file is created in this step.

However, you can also send output from the Postscript renderer directly to a Postscript device, or output from the PCL renderer directly to a PCL device. PDF is the best supported output format.

It is also the most accurate with text and layout. This creates a PDF document that is streamed out as each page is rendered. This means that the internal page index information is stored near the end of the document. The PDF version supported is 1. These fonts, or suitable substitute fonts with the same metrics, are guaranteed to be available in all PDF viewer applications.

One workaround is to use Adobe Acrobat the full version, not the Reader to process the file manually or with scripting that it supports. Another popular post-processing tool is iText , which has tools for adding security features, document properties, watermarks, and many other features to PDF files.

Caveat: iText may swallow PDF bookmarks. However the principles for using iText for other PDF features are similar. Check the iText tutorial and documentation for setting access flags, password, encryption strength and other parameters.

In addition to the PDF Post-processing options, consider the following workarounds:. For example, make region-before large enough to contain your image. Then include a block if necessary, use an absolutely positioned block-container containing the watermark image in the static-content for the region-before.

Note that the image will be drawn on top of the normal content. To use the extensions the appropriate namespace must be declared in the fo:root element like this:. You can give a name and a description of the file. The "src" property is used to reference the file that is to be embedded.

The "filename" property is optional. An optional description can also be added to further describe the file attachment. It is also possible to reference an embedded file from an fo:basic-link. In that case, the user will have to open he attachment via the separate list of file attachments. In Adobe Reader and possibly other PDF viewers , in the Document Properties window, there is a tab that shows custom properties that have been set on the document:.

They can be set in the FO document using the pdf:info extension element as a child of fo:declarations :. Each custom property must be specified using the pdf:name element. Linearization is helpful to allow viewing of a pdf over a slow connection. Needs to be enabled using fop. The PostScript renderer has been brought up to a similar quality as the PDF renderer, but may still be missing certain features.

The default value for the "auto-rotate-landscape" setting is "false". Setting it to "true" will automatically rotate landscape pages and will mark them as landscape. The default value for the "language-level" setting is "3". Set this to "2" only if you don't have a Level 3 capable interpreter. The default value for the "optimize-resources" setting is "false". Setting it to "true" will produce the PostScript file in two steps. A temporary file will be written first which will then be processed to add only the fonts which were really used and images are added to the stream only once as PostScript forms.

This will reduce file size but can potentially increase the memory needed in the interpreter to process. The default value for the "safe-set-page-device" setting is "false". The default value for the "dsc-compliant" setting is "true". Setting it to "false" will break DSC compliance by minimizing the number of setpagedevice calls in the postscript document output.

This feature may be useful when unwanted blank pages are experienced in your postscript output. The default value for the "rendering" setting is "quality". Setting it to "size" optimizes rendering for smaller file sizes which can involve minor compromises in rendering quality. For example, solid borders are then painted as plain rectangles instead of the elaborate painting instructions required for mixed-color borders.

It should produce output as close to identical as possible to the printed output of the PDFRenderer within the limitations of the renderer, and output device. PCL 5 is used for text, raster graphics and rectangular fill graphics. Text or graphics outside the left or top of the printable area are not rendered properly.

In general, things that should print to the left of the printable area are shifted to the right so that they start at the left edge of the printable area. All fonts available to the Java2D subsystem are usable. The texts are painted as bitmap much like the Windows PCL drivers do.

Monochrome output is the default, color needs to be enabled in config. PCL5c color extensions will only be implemented on demand. By default color and grayscale images are converted to monochrome bitmaps 1-bit. Dithering only occurs if the JAI image library is available. Images are scaled up to the next resolution level supported by PCL 75, , , , , dpi. For color and grayscale images an even higher PCL resolution is selected to give the dithering algorithm a chance to improve the bitmap quality.

Currently, there's no support for clipping and image transparency, largely because PCL 5 has certain limitations. The default value for the "rendering" setting is "speed" which causes borders to be painted as plain rectangles. In this mode, no special borders dotted, dashed etc. If you want support for all border modes, set the value to "quality" as indicated above.

This will cause the borders to be painted as bitmaps. The default value for the "text-rendering" setting is "auto" which paints the base fonts using PCL fonts.

Non-base fonts are painted as bitmaps through Java2D. If the mix of painting methods results in unwelcome output, you can set this to "bitmap" which causes all text to be rendered as bitmaps. The default value for the "disable-pjl" setting is "false". PJL commands can be disabled if you set this value to "true". The default value for "image" mode is monochrome output, use "mode" equals "color" to enable color output. The actual value will be rounded up to the next supported PCL resolution.

Currently, only and dpi are supported which should be enough for most use cases. Note that this setting directly affects the size of the output file and the print quality. The page-source extension attribute on fo:simple-page-master allows to select the paper tray the sheet for a particular simple-page-master is to be taken from. Note: the tray number is a positive integer and the value depends on the target printer. Not all PCL printers support the same paper trays.

Usually, "1" is the default tray, "2" is the manual paper feed, "3" is the manual envelope feed, "4" is the "lower" tray and "7" is "auto-select". Consult the technical reference for your printer for all available values. The output-bin extension attribute on fo:simple-page-master allows to select the output bin into which the printed output should be fed.

Note: the output bin number is a positive integer and the value depends on the target printer. Not all PCL printers support the same output bins. Usually, "1" is the upper output bin, "2" is the lower rear output bin. The duplex-mode extension attribute on fo:simple-page-master allows to select the duplex mode to be used for a particular simple-page-master. Note: the duplex is a positive integer and the value depends on the target printer. Not all PCL printers support duplexing.

Usually, "0" is simplex, "1" is duplex long-edge binding , "2" is duplex short-edge binding. FOP does not create document indices. AFP has grown in functionality over time and not every environment supports the latest features.

We're trying to make AFP output work in as many environments as possible. However, to make AFP output work on older environments it is recommended to set to configuration to 1 bit per pixel see below on how to do this. In this case, all images are converted to bi-level images using IOCA function set 10 FS10 and are enclosed in page-segments since some implementation cannot deal with IOCA objects directly. If a higher number of bits per pixel is configured, FOP has to switch to at least FS11 which may not work everywhere.

The AFP Renderer requires special configuration particularly related to fonts.
