http://nagoya.apache.org/bugzilla/show_bug.cgi?id=6992 from-parent function returns invalid values Summary: from-parent function returns invalid values Product: Fop Version: 0.20.3 Platform: PC OS/Version: Windows NT/2K Status: NEW Severity: Normal Priority: Other Component: pdf renderer AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] I believe that from-parent is returning an unknown value if the property is not directly set. The value is the unit of measure if the value is set. Here are the two test cases. If the containing block is thus <fo:block-container height="135mm" width="75mm"> (No top property set) then <fo:block-container . . . top="from-parent(top)-3mm" . . . > returns this error: [ERROR]: Error in top property value 'from-parent(top)-3mm': org.apache.fop.fo.expr.PropertyException: Non numeric operand in subtraction If the containing block is thus <fo:block-container height="135mm" width="75mm" left="4mm" top="4mm"> This error is returned [ERROR]: unknown length unit 'mm-3mm' Here is the complete test case supplied by Sebastien Foucault: This test case works in FOP-0.20.2 <?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 master-name="simplet" page-width="240mm" page-height="100mm" margin-top="1in" margin-right="1in" margin-left="1in" margin-bottom="1in"> <fo:region-before extent="1in"/> <fo:region-body margin-top="1in"/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="simplet"> <fo:static-content flow-name="xsl-region-before"> <fo:block>Region before </fo:block> </fo:static-content> <fo:flow flow-name="xsl-region-body"> <fo:block-container height="135mm" width="75mm" left="4mm" top="4mm"> <fo:block>Region body</fo:block> <fo:block-container height="15mm" width="15mm" left="4mm-3mm" top="from-parent(top)-3mm" position="absolute"> <fo:block>HELLO</fo:block> </fo:block-container> <fo:block>Region body</fo:block> </fo:block-container> </fo:flow> </fo:page-sequence> </fo:root> --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
