-Since the intream object that contains the SVG returns a single fo area then -the construction of the SVG document is handled differently.

This is then stored as a DOM until required for rendering. +The rendering process depends on the what type of renderer is being used.

-The SVG document is then held as a DOM tree which is then rendered by going through -the elements of the tree and rendering then in turn. +The SVG DOM is rendered in the PDF renderer by using the abitlity of Batik to render +DOM to a Graphics2D. First the DOM is converted into an intermediate representation +then this is rendered to a PDFGraphics2D graphic object which writes the drawing +instructions directly as PDF markup. +

+The AWTRenderer and the PrintRenderer use Batik directly to draw the SVG image +into the current java Graphics2D context.

+FOP uses Batik directly for its SVG support. Therefore FOP supports the same +elements and properties as are supported by Batik. As FOP is designed for +rendering to a static medium then only static SVG is rendered. +

+

+Due to some limitations in PDF some SVG images, particularly ones with effects +or transparency, may not come out correctly. The images should still be rendered +correctly for the AWT and Print renderers. +

Another secondary goal is to promote the conversion of SVG into PDF. The most natural mechanism for doing so is within - fo:instream-foreign-object FO's. The powerful graphics offered by both SVG and PDF are a natural fit, and it is - desirable that FOP natively supports an SVG content processor for the fo:instream-foreign-object. +

Another secondary goal is to improve the conversion of SVG into PDF. + This includes the use of FOP to work as a transcoder for Batik to convert + an SVG document into a PDF document and the fully support embedding SVG inside + fo documents in an fo:instream-foreign-object.

A final secondary goal is the continued refinement of the FOP design and implementation.

    +FOP uses the SVG library from Batik to handle SVG. +This format can be handled as an fo:instream-foreign-object or in a separate +file referenced with fo:external-graphic. Either way the SVG document will be +read in and converted into a DOM in Batik. This DOM will then be used by the renderer to +create the graphical image. +

    +

    +The AWT and Print renderers simply use batik to draw the SVG into a graphic. +

    +

    +In the case of the PDF renderer there is a PDFGraphics2D class that Batik uses +to render the image into. This class converts the drawing instructions into +PDF markup which is placed into the current PDF document. +

    +     + + +

    +It is possible to convert a standalone SVG document directly into a simple page PDF document. +This is possible through the use of Batik's transcoder mechanism.
    +java org.apache.batik.apps.rasterizer.Main -m application/pdf document.svg +
    +This will output the svg document as "document.pdf" containing a PDF rendering of +the SVG file. +

    +

    +It is also possible to specify the width and/or height of the PDF document. +Currently the SVG image is simply scaled in PDF so the result my not be the best possible. +

    +Testing is an important part of getting FOP to operate correctly and conform to the +necessary standards. +

    +

    +A testing system has been set up that works with as a build target when developing +with FOP. A developer can run the tests after making changes to the code, the aim +is to have the tests run to verfiy that nothing working has been broken. +

    +

    +To setup the testing the developer must place a reference fop.jar in the +"<cvs_repository>/test/reference/" directory. This jar will be dynamically +loaded to create the reference output. +

    +     + + +

    +A test belongs to one of a few catagories. A basic test should excercise one +element in a number of situations such as changing a property. This should have +at least one normal value, one border value and one invalid value. If the property +can be of different types then this should also be included. +

    +

    +A bug test is a test that is specifically aimed at a problem with FOP. That is, the test +is not excercising the specification but rather a problem with FOP in handling a particular +situation that is not exposed with the other testing. +

    +

    +A system test is one that tests the abitlity of FOP to handle a number of different +elements together. +

    +

    +A test can consist of a complete fo document or a part of the document such as +some elements that will be placed into the flow of a standard document. +

    + +     + +

    +If you have a test which you think would be useful you should supply the +test and a diff to the appropriate test suite xml file. Make sure that the +test works as would be expected against the current build. +

    +     + + +

    +The tests are stored in the "<cvs_repository>/test" directory. +

    +

    +You can run the tests by specifying the build target "test" ie:
    +build.sh test +

    +

    +This will then compare the current code in the local src directory to a specified +release of FOP. Any differences between the current code and the output from +the reference version will be reported. If the test previously passed then the +test run will have failed. +

    +

    +The testing is done by reading a test suite xml file, which corresponds to the +standard testsuite.dtd supplied from w3c. This xml file contains a test xml +file and an xsl file (which may simply copy the file). It also contains information +such as if the test has passed and any comments. +

    +

    +For FOP the testing is done by rendering all the testing documents using the +XML renderer. The XML files are then compared to see if there are any differences. +

    +     + + +

    +The testing of SVG is not part of this testing system. SVG is tested for its rendering +accuracy by using the transcoding mechanism via Batik. So that the only part that needs +testing is how the SVG image is embedded inside the flow of the fo document. +
