The table below summarizes the theoretical support for graphical formats within FOP. In other words, within the constraints appache the limitations listed here, these formats should work.

However, many of them have not been tested, and there may be limitations that have not yet been discovered or documented.

The packages needed to support some formats are not included in the FOP distribution and must be installed separately. Follow the links in the “Support Thru” column for more details.

First, download and install it. Then, copy the file “JimiProClasses. See What platforms are supported? It is automatically installed with FOP.

Batik must be run in a graphical environment. If you run a server without X, or if you can’t connect to the X server due to security restrictions or policies a so-called “headless” environmentSVG rendering will fail.

FOP Graphics Formats

FOP native support of JPEG does not include all variants, especially those containing unusual color lookup tables and color profiles. Specifying bit color output may also help. Apacne format can be handled as an fo: This means that the graphical objects created with this remain as vector graphics. Parts of the graphic such as effects, patterns and images are inserted into the Fopp as a raster graphic.

The resolution of this graphic may not be ideal depending on the FOP dpi 72dpi and the scaling for that graphic. We hope to improve this in the future.

Currently transparency is not supported in PDF so many svg images that contain effects or graphics apachr transparent areas will not be displayed correctly. If possible, Batik will use normal PDF text when inserting text.

It does this by checking if the text can be drawn normally and the font is supported. This example svg text. Note that tspan and outlined text are not yet implemented.


Otherwise, text is converted and drawn as a set of shapes by batik, using the stroking text painter. This means that a typical character will have about 10 curves each curve consists of at least 20 characters. This can make the pdf files large and ep the pdf is viewed the viewer does not normally draw those fine curves very well aapche on Smooth Line Art in the Acrobat preferences will fix this.

The drawback to this approach is that it is effective only for available fonts including embedded fonts.

Font sizes are rounded to the next integer point size. This will be improved in the future. Note that because SVG text can be rendered as either text or a vector graphic, you may need to consider settings in your viewer for both.

This setting will not affect the printing of your document, which should be OK in any case, but will only affect the quality of the screen display.

Currently, SVG apaxhe are rendered with the dimensions specified in the SVG filewithin the viewport specified in the fo: For everything to work properly, the two should be equal. The SVG standard leaves this issue as an implementation detail. FOP will probably implement a scaling mechanism in the future. Also, according to user reports, FOP’s native support for TIFF is limited to images with the following characteristics all must be true for successful rendering:.

Some bitmapped image file formats store a dots-per-inch dpi or other resolution value.

Since PDF and most output formats do not have a concept of resolution, but apaceh of absolute image units i.

Instead, FOP uses the dimensions of the image as specified in the fo: If you need a higher apparent output resolution for bitmapped images, first make sure that at least one dimension of the image is defined in your XSL-FO input. Apart from that, resolution problems are in the image file itself, and must be corrected there: FOP caches images between runs.

The URL is used as a key to identify images which means that when a particular URL appears again, the image is taken from the cache.


If you have a servlet that generates a different image each time it is called with the same URL you need to use a constantly changing dummy parameter on the URL to avoid caching. Currently, the images are not automatically released when an OutOfMemoryError is imminent. The image cache can grow to a considerable size over time when a lot of different URLs are in use.

Starting with version 0. Image caching will be improved as part of our redesign effort. See TIFF for more details. JAI support is available for Release 0.

EPSTranscoder (Apache FOP API)

The comments in this section do not apply to releases earlier than 0. FOP provides support for two output targets: Apacbe images are not inserted directly into the pdf document This area has not been implemented yet since the appropriate method in batik is static Uniform transparency for images and other svg elements that are converted into a raster graphic are not drawn properly in PDF. The fpo is opaque. Also, according to user reports, FOP’s native support for TIFF is limited to images with the following characteristics all must be true for successful rendering: If no dimensions are given, FOP uses a default value of 72 dpi to compute the graphic’s dimensions.

For example, suppose a graphic pixels wide and pixels high.

gop FOP will render the graphic at 4. If only one dimension is given, FOP by default uses the same aspect ratio to compute the other dimension to avoid the appearance of stretching. If both dimensions are given, FOP simply renders the image in that space. FOP will render the graphic at that size, with an apparent resolution of dpi. The explanation above describes only the basic default behavior.

There are other attributes of the fo: FOP native limited support, see restrictions below.
