If I load an xlsx file that already has a filter, and then save the file using GemBox, it seems to throw my filtering cell away. Does GemBox support filtering at all? I know I can load the file in preserved mode but my intention is to create the filter in my C# app.
EDIT 2015-06-15:
The newer version of GemBox.Spreadsheet (version 3.9) does have an API support for filters, see the version history page. Also, you can find here an Excel AutoFilter example.
ORIGINAL ANSWER:
Unfortunately, in the current version (3.5) GemBox.Spreadsheet supports filtering only through preservation.

I just installed Tika from the Github's repository and tried to OCR a PDF which contains scanned document pages.
java -cp tika-app/target/tika-app-1.17-SNAPSHOT.jar org.apache.tika.cli.TikaCLI /tmp/testing/sample_scanned.pdf
However, only metadata gets extracted (although I got confirmation beforehand that Tesseract is installed and utilized:
WARNING: Tesseract OCR is installed and will be automatically applied to image files unless
you've excluded the TesseractOCRParser from the default parser.
Tesseract may dramatically slow down content extraction (TIKA-2359).
As of Tika 1.15 (and prior versions), Tesseract is automatically called.
In future versions of Tika, users may need to turn the TesseractOCRParser on via TikaConfig.
(Full output)
Note: Regular PDFs (containing) plain text gets extract successfully. The problem seems to be the OCR process itself.
This has been tested on Centos as well as Ubuntu - same issue.
Do I need to make changes to config files, specify more parsers? What could cause this?
Thank you.
Turns out PDF image extraction is disabled by default. From PDFParserConfig:
Beware: some PDF documents of modest size (~4MB) can contain thousands of embedded images totaling > 2.5 GB. Also, at least as of PDFBox 1.8.5, there can be surprisingly large memory consumption and/or out of memory errors. Set to true with caution. The default is false.
A simple example to enable it that worked for me:
Parser parser = new AutoDetectParser();
ContentHandler handler = new BodyContentHandler(Integer.MAX_VALUE);
ParseContext parseContext = new ParseContext();
PDFParserConfig pdfConfig = new PDFParserConfig();
pdfConfig.setExtractInlineImages(true);
parseContext.set(PDFParserConfig.class, pdfConfig);
try (InputStream stream = ClasspathUtil.readStreamFromClasspath("test.pdf")) {
parser.parse(stream, handler, new Metadata(), parseContext);
System.out.println(handler.toString());
}
I want to make a network graph which shows the distribution of our documents in our folder structure.
I have the nodefile, edgefile and gephi graph file in this location:
https://1drv.ms/f/s!AuVfRBdVHkO7hgs5K9r9f7jBBAUH
What I do is:
Run the algorithm ForceAtlas2 with scaling 10-20, dissuade hub marked and prevent overlap marked, all other standard setting.
What I get is a graph with groups radial/spherical distributed. However, what I want is a tree directed network graph.
Anyone know how I can adjust Gephi to make this?
Thanks!
I just found a solution.
I tested the file format as shown on the Yed site "import excel file" page
http://yed.yworks.com/support/manual/import_excel.html
This gave me the Yed import dialog (took a life time to figure out that it's a pop up menu and not selectable through the standard menu)
Anyway, it worked and I've adjusted the test files with the data prepared for the Gehpi. This was pretty easy, I could used the source target ID's etc. Just copy paste.
I load it into Yed and used some directed and radial clustering algorithms on it. Works fine!
Below you can find the excel node/edge file used to import in Yed and the graph file you can open with Yed to see the final radial result.
https://1drv.ms/f/s!AuVfRBdVHkO7hg6DExK_eVkm5_mR
Only thing to figure out is how to combine the weight (which represents the number of documents) with the node size.
Unfortunately, as of version 0.9.0, Gephi no longer supports hierarchical graphs. Maybe try using a previous version?
Other alternatives involve more complex software, such as Graphviz, but you need a .dot file instead of your .csv. I looked all over, but could not find an easy-to-use csv to dot converter.
You could try looking at d3-hierarchy, a node.js program, but then again you need to use the not-so-user-friendly npm. If you look at the link, it looks like it can produce the kind of diagram you're looking for.
I´m having some problems to create reports in my server without default export engine.
I´m using SpudSoft to create it. I have the following configuration:
Tomcat 7
Birt 4.2.2
uk.co.spudsoft.birt.emitters.excel_0.8.0.201310230652.jar
And i followed this tutorial:
spudsoft-birt-excel-emitters
I haven´t include this file
lib/slf4j-api-1.6.2.jar
because it´s not included in the *.jar file
and either wrote this code:
'if( "XLS".equalsIgnoreCase( outputFileFormat ) ) {
renderOption.setEmitterID( "uk.co.spudsoft.birt.emitters.excel.XlsEmitter" );
} else if( "XLSX".equalsIgnoreCase( outputFileFormat ) ) {
renderOption.setEmitterID( "uk.co.spudsoft.birt.emitters.excel.XlsxEmitter" );
}'
Because I dont really know where to use it.
to run my report i use the following URL
http://127.0.0.1:8090/birt-viewer/frameset?__format=xls&__report=informes/myReport.rptdesign&__emitterid=uk.co.spudsoft.birt.emitters.excel.XlsEmitter
and i get the following message:
org.eclipse.birt.report.service.api.ReportServiceException: EmitterID uk.co.spudsoft.birt.emitters.excel for render option is invalid.
What can i do to run SpudSoft report? I've been reading for a week and I haven´t found any solution!
Thanks a lot for all!
#Dominique,
I recommend upgrading from the emitter included with BIRT 4.3 (and given the lack of responses from the BIRT team I regret letting them put it in there).
Also, you don't need to use a specific IRenderOption type - they are all the same really anyway.
#Jota,
If you are getting that error it means that BIRT hasn't picked up the emitter correctly (you do have the correct emitter ID).
I don't use the BIRT war file, so my instructions aren't aimed at that approach (I just use the report engine in my own service).
The code snippet is no use for you, it's just a way to specify the emitter ID, which you are doing on the query string.
slf4j shouldn't be needed with the version of the emitter that you have - it uses JUL instead (I hate JUL, but it's one fewer dependency).
Can you post a complete listing of the jar files in your war?
It seems because you make use of a generic IRenderOption. With spudsoft emitter you should instantiate your render options like this:
EXCELRenderOption excelOptions = new EXCELRenderOption();
Note if you upgrade to BIRT 4.3 you don't have to set the emitter anymore, it is embedded
I have about 10 .f3d models and need to convert to zf3d. Any idea if there is simple solution for this ?
Many thanks.
Eugene
F3D format is no longer supported (a new and optimized F3D version is now in developing and will be ready for a future Flare3D version).
If you want to use old F3D models you can convert them using Flare3D IDE.
Drag and drop the old model into the IDE, and saving it you will get a ZF3D instead the original F3D.
I've a couple of rdlc files which I change everytime business has additional requirements. The problem is that we keep pdfs of the reports we create, and it's impossible right now to see what version of the rdlc file it was created with.
I've thought about putting a text field with "Version XX.Y" into the footer, but then I have to remember to update this when I make changes. It's not the worst solution in the world, but I'd like to hear how others handle report versioning in reporting services.
Note that I am renedering reports using local reporting, i.e. no server, so I've thought about somehow trying to display the assembly version of the application running the report. This I can control more easily with .* notation in assemblies, but I'm not sure how to have a text field which would show this.
You could add a property containing the assembly version to the report's data source (or pass the value in some other way).
public string AssemblyVersion {
get {
return Assembly.GetAssembly(typeof(WhateverTypeThisIs)).GetName().Version;
}
}
Another option might be to use an MSBuild task to replace the version number in the .rdlc for you. XMLPoke, for instance.
If you are using subversion, an option might be to use the SvnInfo task from MSBuild community tasks to get the last changed rev of the report and use that number to update the XML of the rdlc file.
