Is it possible to convert PPTX to image in android using PPTX4J? Kindly help me in this regards. I have to develop an application which will convert powerpoint slides into images in Android.

I am currently working to get docx4j running on Android for a paying customer, so some results should be available in due course.

In the meantime, you might want to ensure your PPTX to image output is satisfactory in an ordinary Java environment.

https://github.com/plutext/docx4j/tree/android is docx4j working on Android, and tested insofar as it can convert docx to HTML using https://github.com/plutext/docx4j/blob/ ... nXSLT.java

It seems XSLT Xalan extension functions must be avoided on Android, and with that, https://github.com/plutext/docx4j/tree/ ... /svginhtml

I am facing a peculiar type of problem .
i am able to convert pptx file to image as well as into html in java using Docx4j but it is NOT working in android it throwing an error

Could not find method org.pptx4j.convert.out.svginhtml.SvgExporter.setImageDirPath, referenced from method com.example.prototype.pptimageandroid.PPTIamge.pptHTML
i have required jar files in the referenced libraries.
it is throwing a runtime Error.
Please help me on this.

I have answered your cross post at http://stackoverflow.com/questions/1397 ... conversion along the same lines as the answer earlier in this thread.

Please mark the question on StackOverflow as answered.

I used AndroidDocxToHtml to read Docx as HTML and it is Working absolutely fine on android but when i am trying to use your SVGExporter for PPTX reading as HTML on android it is throwing exception on PresentationMLPackage.load method may be becoz of it is internally using javax api NOT supported by android.
Exception is

Please Suggest me a Solution for using PresentationMLPackage Class or any other suitable class if any, to convert PPTX into html.

Thanks in Advance

PresentationMLPackage class is NOT working with Android hence i am not able to use it for PPTX reading as HTMl

Please suggest me the method through which i can be able to run SvgExporter or even PresentationMLPackage run on android as both are not working on android but they are working fine on Java

Your stack trace is coming from:



You should work out why you are getting the error java.io.IOException: Mark has been invalidated.

You may be able to work around this by using OpcPackage.load(bis, Filetype.ZippedPackage, null);

Thanks for the suggestion. I tried by using OpcPackage.load(bis, Filetype.ZippedPackage, null);
Now it is thowing Exception as

in the grepCode , Link ... http://grepcode.com/file/repo1.maven.or ... .String%29
it is showing that SlideSizesWellKnown.java class does not contain method as valueOf(String) but in the API doc given @

valueOf(String)method is mentioned.
why this discrepancies although both have same version of doc4xJ i.e 2.7.1 .
I am using docx4J 2.8.1.

Please Help.

You'll need to ask the people who run those sites.

The "official" docx4j stuff is found:
(1) https://github.com/plutext/docx4j
(2) on this website, including the old svn repository
(3) in Maven Central

The jar ae-docx4j-2.8.0-SNAPSHOT.jar at https://github.com/plutext/AndroidDocxT ... aster/libs is the one that I got working on Android.

The source code is at https://github.com/plutext/docx4j/tree/android

You can't expect ordinary docx4j to work on Android, until ordinary JAXB does.

Thanks again,
I am using the same Jar files downloaded from https://github.com/plutext/AndroidDocxT ... aster/libs.
I have also tried your code AndroidDocxToHtml and that is working absoultely fine on android, that's why i asked if i am using the very same lib that u had used then why it is NOT able to processed PresentationMLPackage . ?

Here is the source code of that class: https://github.com/plutext/docx4j/blob/ ... Known.java

You are probably going to make progress here fastest if you download and work with the source code.

Having just looked at the contents of the jar, I find the pptx4j classes are not there, which explains what you are seeing.

This was probably in order to slip under the Dalvik limit of 65536 method references per dex file .. see http://www.docx4java.org/blog/2012/05/j ... n-android/

So you'll need to compile it yourself.

I took all the remaining class files (that was there in the contents of the jar eg- pptx4j class files ) and merge with the contents of the jar file now I am not able to re-Jar it. can u please tell me how to make an executable jar file for ae-docx4j-2.8.0-SNAPSHOT folder ?
Explanation :--

ae-docx4j-2.8.0-SNAPSHOT -- this was used for AndroidDocxToHtmlActivity by you. and it didn't have pptx4j class files. I took those required class files and merge with the ae-docx4j-2.8.0-SNAPSHOT. Now I have to make this executable jar file again. I hope u have understood my question.

Thanks.

Easiest to just do it properly: get the Android branch of docx4j from GitHub, then run either ant dist or mvn install (just as you would for docx4j proper)

Can you please give me the link for the Android branch of docx4j from GitHub as i have downloaded the docx4j from Github am i am notsure if it is adroid supported or not.
also give the command to run that .

Thanks

At https://github.com/plutext/docx4j click the branch dropdown, and select branch "Android"

Beyond that, you are asking for more than I have bandwidth to provide by way of free support.

Generic questions relating to git, GitHub, maven and ant should be asked elsewhere.

As per my earlier post, once you have the android branch cloned locally, run either ant dist or mvn install. If you use ant, you'll need to adjust the paths to point to the various dependencies.

Thanks a lot
I will keep note of that what u said.(regarding question like ant and github).

I made a jar consisting all the class files for pptx.
When i put that jar file into the libs/ directory apk is fialed to get installed and throwing error as

[2013-01-17 15:29:09 - PPT2HTML] Installation error: INSTALL_FAILED_DEXOPT
[2013-01-17 15:29:09 - PPT2HTML] Please check logcat output for more details.
[2013-01-17 15:29:09 - PPT2HTML] Launch canceled!

When i want to access the file throw referenced lib it is throwin same error as earlier i.e NoClassDef Error.
can there be an issue with the jar file ?
Please help.

Those log messages are from your application PPT2HTML, not from docx4j

Can you post a complete stack trace?

this is generating when I put newly created jar file in the libs/ directory if i remove that jar file App install succesfully.

Google 'E/installd(34): dexopt failed res'

You may be running into the 65K method limit? In which case you'll have to try removing some classes you don't need. In the docx4j jar, you could remove org.xlsx4j for a start.

If Google doesn't answer it for you, I suggest you post your question in some forum where there are more android experts. But please report back when you have something to share.

Thanks for the suggestions.
as per you suggestion i removed xlsx classes and make jar and laod in the lib/ dir.
application started. but it is throwing Exception as
