Renderer Analysis
In order to learn the page geometry I built a trace into the PDFRenderer. Then I found that SVG can be written easily at the trace points. An analysis of the results follows. Coordinates (o) received by the renderer: PDF with origin left/bottom PDF Rectangle ||| ||| ||+--- |o +- Line +--- o- +- Coordinates used by SVG with origin left/top Rectangle o- |+ ||+--- ||| ||| Line o--- |- +- _ Text Block o There is a hidden overpainting priority: last one in time sequence wins The blue background rectangle descFilledRect/desc rect x=70 y=115 width=453 height=-22 fill=rgb(0.0,0.0,255.0)/ o FOP sends a negative height with corresponding reference coordinates: not suppported by SVG Borders descFilledRect/desc rect x=70 y=113 width=453 height=2 fill=rgb(255.0,0.0,0.0)/ descFilledRect/desc -- rect x=68 y=113 width=2 height=26 fill=rgb(255.0,0.0,0.0)/ descFilledRect/desc rect x=524 y=113 width=2 height=26 fill=rgb(255.0,0.0,0.0)/ descFilledRect/desc rect x=70 y=138 width=453 height=2 fill=rgb(255.0,0.0,0.0)/ o Painted by 4 rectangles o Left border is shifted out into the left margin -- o Shipping borders as filled rectangles - prevents correct SVG positioning - dotted, dashed borders (anyway no properties available at present) Text text x=70 y=131 font-size=18 font-family=sans-serif fill=rgb(255.0,255.0,0.0)linked_to/text text x=147 y=131 font-size=18 font-family=sans-serif fill=rgb(255.0,255.0,0.0)text2/text text x=191 y=131 font-size=18 font-family=sans-serif fill=rgb(255.0,255.0,255.0)inline/text text x=238 y=131 font-size=18 font-family=sans-serif fill=rgb(255.0,255.0,0.0)text2/text An Image descrenderImage URL file:C:/HU/alt/Fop-0.20.1/docs/graphics/fop.jpg/desc rect x=70 y=156 width=100 height=60 / o Reference coordinates top/left o How big is an image given pixels/lines and rows without resolution? The formatter has to know the extent of the image and no more. o The renderer has to handle various image formats and cache images if needed at all. o As a courtesy the formatter can determine image formats and some image properties as a common task, e.g. - pixels/lines and rows to allow a proportional scaling - color model - compression o Java 1.4's Advanced Imaging and Image I/O will allow a comfortable programming o If the basics of image and PDF are known, image processing is a file copy.

PDFRenderer has lots of unused code. o A precise page geometry has to be calculated by the formatter: spaces, (collapsing) borders, padding. o Know the features of PDF and Java: correct graphic object (line, rectangle, PDF path and stroke), caching, ressource management. A formatter formats and a renderer renders. A strict separation is desirable (keyword: device independence)- very few mutual imports. The formatter needs only area dimensions and has to pass data to the renderer instead of controlling and pushing it. xsl:fo input has to be setup, so that the formatter just has to process text. No digging
AW: printing the correct document
Guten Tag, schicken Sie mir die Input xsl:fo? Dann kann ich den Fall einmal anschauen. Mit freundlichen Gruessen Hansuli Anderegg Tel. 01-381-0207 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
