Hello, I've been working on a project to transform XML to TIFF in the CITT G4 Format and have read several threads regarding the conversion, which has lead me to believe conversion is a common problem among users.
Most of the G4 TIFF-related threads end with guru JM providing an explanation, but with no follow-up response from the thread-starting user as to whether the explanation/solution worked. I promise if my issue gets resolved, I will post a success story as a follow-up to this thread. Here is my situation: I am trying to convert a FOP-readable xml file into a G4 TIFF. No matter what I do, it applies as PackBits. In addition to resolving this, I am curious as to why there appears to be no programmatic way to set CCITT compression within the code (ex: a setCompression(String) method), when TIFFRenderer even contains String constants representing the three available compression types. Also, I could not find a sample configuration file in the distribution; maybe I missed it. Any help / advice would be much appreciated, thanks. -Josh (details follow) JARS on CLASSPATH: avalon-framework-4.2.0.jar batik-all-1.6.jar commons-io-1.3.1.jar commons-logging-1.0.4.jar fop.jar (implementation.94) serializer-2.7.0.jar xaland-2.7.0.jar xercesImpl-2.7.1.jar xml-apis-1.3.02.jar xmlgraphics-commons-1.2.jar log4j-1.2.13.jar jai-imageio.jar (implementation 1.1) FILES: There are 3 files involved in this (contents follow) FILE 1 - testFop.xml This is the fop formatted xml; I've successfully transformed it to PostScript and Tiff. FILE 2 - tiffFopConfig.xml This only contains the compression line for CCITT T.6 FILE 3 - FopTiffTester.javaThis is the java file for conversion. The code is abstracted from my own larger codebase where I do instantiate a single fopFactory and perform best practices - no need for best practices on this example, IMHO. :-) FILE CONTENT: FILE 1 - testFop.xml <?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-top="0.0in" margin-bottom="0.0in" page-width="8.5in" page-height="11.0in" master-name="single"> <fo:region-body padding="0pt 0pt" margin-bottom="0cm" margin-top="0.5cm" margin-right="1cm" margin-left="1cm"/> <fo:region-before padding="0pt" display-align="after" extent="1cm" region-name="left-top"/> <fo:region-after padding="0pt" display-align="before" extent="1cm" region-name="footer"/> <fo:region-start padding="0pt" display-align="center" precedence="true" extent="1in" region-name="outside"/> <fo:region-end padding="0pt " display-align="after" precedence="true" extent="1in" region-name="inside"/> </fo:simple-page-master> <fo:page-sequence-master master-name="contents"> <fo:repeatable-page-master-reference master-reference="single"/> </fo:page-sequence-master> </fo:layout-master-set> <fo:page-sequence initial-page-number="2" master-reference="contents"> <fo:flow flow-name="xsl-region-body"> <fo:table width="100%" table-layout="fixed"> <fo:table-column column-width="19cm"/> <fo:table-body> <fo:table-row> <fo:table-cell font-size="9pt" font-family="Helvetica"> <fo:block line-height="14pt"> <fo:block white-space-collapse="true"> <fo:block font-family="Helvetica" font-size="10pt">Test test test test test times five.</fo:block> </fo:block> </fo:block> </fo:table-cell> </fo:table-row> </fo:table-body> </fo:table> </fo:flow> </fo:page-sequence> </fo:root> FILE 2 - tiffFopConfig.xml <fop version="1.0"> <renderer mime="image/tiff"> <compression>CCITT T.6</compression> </renderer> </fop> FILE 3 - FopTiffTester.java import java.io.BufferedOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.OutputStream; import java.io.StringReader; import java.net.URL; import javax.xml.transform.Source; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXResult; import javax.xml.transform.stream.StreamSource; import org.apache.avalon.framework.configuration.Configuration; import org.apache.avalon.framework.configuration.DefaultConfigurationBuilder; import org.apache.commons.io.FileUtils; import org.apache.fop.apps.FOUserAgent; import org.apache.fop.apps.Fop; import org.apache.fop.apps.FopFactory; import org.apache.fop.apps.MimeConstants; import org.apache.log4j.helpers.Loader; public class FopTiffTester { public FopTiffTester() {} public static void main(String[] args) { try { // Load the File Objects File testPath = new File("C:\\test\\foptifftest\\"); testPath.mkdirs(); File fopFile = new File(testPath, "testFop.xsl"); File tiffFile = new File(testPath, String.valueOf(System.currentTimeMillis()) + ".tiff"); // Read FOP File to String String fopString = FileUtils.readFileToString(fopFile); // Get Fop Factory and Configure FopFactory fopFactory = FopFactory.newInstance(); URL configUrl = Loader.getResource("tiffFopConfig.xml"); DefaultConfigurationBuilder cfgBuilder = new DefaultConfigurationBuilder(); Configuration cfg = cfgBuilder.build(configUrl.openStream()); fopFactory.setUserConfig(cfg); // Generate Fop User Agent and Configure FOUserAgent fopAgent = fopFactory.newFOUserAgent(); fopAgent.setTargetResolution(200); // Transform Fop to Tiff OutputStream outStream = new BufferedOutputStream(new FileOutputStream(tiffFile)); Fop fop = fopFactory.newFop(MimeConstants.MIME_TIFF, fopAgent, outStream); Transformer transformer = TransformerFactory.newInstance().newTransformer(); transformer.transform((Source)new StreamSource(new StringReader(fopString)), new SAXResult(fop.getDefaultHandler())); outStream.close(); } catch (Exception ex) { ex.printStackTrace(); } } } ----------------------------------------- The information in this message may be proprietary and/or confidential, and protected from disclosure.
