http://nagoya.apache.org/bugzilla/show_bug.cgi?id=23709 Height of table cells negative when rendering SVG Summary: Height of table cells negative when rendering SVG Product: Fop Version: 0.20.5 Platform: PC OS/Version: Linux Status: NEW Severity: Major Priority: Other Component: svg AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Hi, I'm currently using the FOP library to build a Java print engine which transforms Java AWT/Swing screens into HTML, SVG, PDF, etc... (see http://javauitransform.sf.net) When I render the following Fo input into SVG, I always get negative rect heights for fo:table-cells containing the fo:block element. I am relative new to this, but to what I've found, negative rect heights are to be reported as an error (see SVG specs v1.0 page 196). Batik squiggle correctly reports this error as : "The attribute 'height' of the element <rect> can not be negative" I've temporarily fixed this issue by using my own SVGRenderer and subclassing the SVGUtilities class. I've replaced the SVGUtilities.createRect(...) method by SVGUtilities.createAbsoluteRect(...) which creates a rectangle with an absolute value for the height. The following is an example input FO tree : -------------------------------------------------------------- <?xml version="1.0" encoding="UTF-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";> <fo:layout-master-set> <fo:simple-page-master margin-right="0.5cm" margin-left="0.5cm" margin-bottom="0.5cm" margin-top="1cm" master-name="page" page-width="400pt"> <fo:region-body margin-bottom="1cm" margin-top="1cm"/> <fo:region-before extent="1cm"/> <fo:region-after extent="1cm"/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="page"> <fo:flow flow-name="xsl-region-body"> <fo:block background-color="#ffffff"> <fo:table table-layout="fixed" text-align="left" border="0pt"> <fo:table-column column-number="1" column-width="15pt"/> <fo:table-column column-number="2" column-width="15pt"/> <fo:table-column column-number="3" column-width="15pt"/> <fo:table-column column-number="4" column-width="15pt"/> <fo:table-column column-number="5" column-width="15pt"/> <fo:table-column column-number="6" column-width="15pt"/> <fo:table-column column-number="7" column-width="15pt"/> <fo:table-column column-number="8" column-width="15pt"/> <fo:table-column column-number="9" column-width="15pt"/> <fo:table-column column-number="10" column-width="15pt"/> <fo:table-column column-number="11" column-width="15pt"/> <fo:table-column column-number="12" column-width="15pt"/> <fo:table-column column-number="13" column-width="15pt"/> <fo:table-column column-number="14" column-width="15pt"/> <fo:table-column column-number="15" column-width="15pt"/> <fo:table-column column-number="16" column-width="15pt"/> <fo:table-column column-number="17" column-width="15pt"/> <fo:table-column column-number="18" column-width="15pt"/> <fo:table-column column-number="19" column-width="15pt"/> <fo:table-body> <fo:table-row> <fo:table-cell height="20pt" border="0pt" column-number="1" number-columns-spanned="18"> <fo:block background-color="#6464dc"> <fo:table table-layout="fixed" text-align="left" border="0pt"> <fo:table-column column-number="1" column-width="15pt"/> <fo:table-column column-number="2" column-width="15pt"/> <fo:table-column column-number="3" column-width="15pt"/> <fo:table-column column-number="4" column-width="15pt"/> <fo:table-column column-number="5" column-width="15pt"/> <fo:table-column column-number="6" column-width="15pt"/> <fo:table-column column-number="7" column-width="15pt"/> <fo:table-column column-number="8" column-width="15pt"/> <fo:table-column column-number="9" column-width="15pt"/> <fo:table-column column-number="10" column-width="15pt"/> <fo:table-body> <fo:table-row> <fo:table-cell height="15pt" border="0pt" column-number="1"/> <fo:table-cell height="15pt" border="0pt" column-number="2"/> <fo:table-cell height="15pt" border="0pt" column-number="3"/> <fo:table-cell height="15pt" border="0pt" column-number="4"/> <fo:table-cell height="15pt" border="0pt" column-number="5"/> <fo:table-cell height="15pt" border="0pt" column-number="6"/> <fo:table-cell height="15pt" border="0pt" column-number="7"/> <fo:table-cell height="29pt" border="0pt" column-number="8" number-columns-spanned="2"> <fo:block>07</fo:block> </fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:block> </fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:block> </fo:flow> </fo:page-sequence> </fo:root> -------------------------------------------------------------- SVG output : -------------------------------------------------------------- ?xml version="1.0" encoding="ISO-8859-1"?> <svg contentScriptType="text/ecmascript" width="400.0" xmlns:xlink="http://www.w3.org/1999/xlink"; zoomAndPan="magnify" contentStyleType="text/css" height="792.0" preserveAspectRatio="xMidYMid meet" xmlns="http://www.w3.org/2000/svg"; version="1.0"> <g id="Page-1" style="font-family:sanserif;font-size:12" transform="translate(0,0.0)"> <rect width="400.0" x="0.0" height="792.0" y="0.0" style="fill:none;stroke:black"/> <rect width="371.654" x="14.173" height="-239.0" y="56.692017" style="stroke:rgb(255,255,255);fill:rgb(255,255,255)"/> <rect width="270.0" x="14.173" height="-29.0" y="266.69202" style="stroke:rgb(100,100,220);fill:rgb(100,100,220)"/> <text x="119.173" y="276.89203"> 07 </text> <a xlink:href="#svgView(viewBox(0, 0.0, 400, 792))" xlink:type="simple" xlink:actuate="onRequest" xlink:show="replace" xmlns:xlink="http://www.w3.org/1999/xlink";> <rect width="200.0" x="0.0" height="792.0" y="0.0" style="fill:blue;visibility:hidden"/> </a> </g> </svg> -------------------------------------------------------------- Many thanks for your support.
