I've taken a sample Jpeg2000 from the FNordware examples page.
However, when I try to add that image to the PDF:
...ANSWER
Answered 2018-Nov-26 at 13:18From pdfbox's documentation: createFromFileByContent "The following file types are supported: jpg, jpeg, tif, tiff, gif, bmp and png."
Looking into the source code, what gets called inside createFromFileByContent is their own check for known file types, independent from the underlying libraries, the detection code looks like this: https://jar-download.com/artifacts/org.apache.pdfbox/pdfbox/2.0.3/source-code/org/apache/pdfbox/util/filetypedetector/FileTypeDetector.java
This check does not recognize jpeg 2000.
Actually createFromFileByExtension might be a better bet:

My project is building with Leiningen using the pantomime 2.10.0 library [com.novemberain/pantomime "2.10.0"]
which is some Clojure wrapper for Apache Tika. I ground through some documentation at https://pdfbox.apache.org/2.0/dependencies.html to attempt to eliminate WARNings emitted by org.apache.tika.config.InitializableProblemHandler but one seems to persist.

Answered 2018-Sep-07 at 13:50To disable these warnings you need to suppress them in Tika config file.

QUESTION
I am very confused with this issue. I am using 1.3.0 version on jai-imageio-core please check the dependecy below and I am at complete loss to figure out from the jar how can one class file (RawImageReaderSpi) is loaded in JVM but RawImageInputStream is not loaded.
I have deployed my spring boot web service in tomcat 7 container.
This issue pops up randomly and I have noticed that when I have restarted the TC container and deployed new version of my service, this issue shows up intermittently.
Any lead is highly appreciated.
I have spent a day trying to figure out what is wrong and ended up feeling stupid
...ANSWER
Answered 2018-Jan-18 at 15:11The problem here, is a known issue with ImageIO
plug-ins and containers (like a web/servlet container). Deploying plug-ins as part of the web application is not well supported by ImageIO
.
The ImageIO
registry that keeps track of registered plug-ins is in effect JVM global (it is actually a registry per application context, however, there is usually only a single application context*).
The safest option is install the plug-ins (and all their dependencies) in the container's "shared" or "common" lib folder. This ensures that the plug-ins are only installed once, and that they are available to all the container's contexts. This requires control of the container environment, and also may be a hassle to upgrade, due to manual install and full container restart required.
If you prefer to deploy the plug-ins as part of the web application, the only option I know of, is to use the
com.twelvemonkeys.servlet.image.IIOProviderContextListener
as described here.Altenatively, to use it in a Spring Boot project without a
web.xml
file, you can add the following line to theonStartup()
method in yourSpringBootServletInitializer
subclass as described here:
QUESTION
I´m working on a big application and we use Mavem bundle plug in in our proxy to make it small! I´m having problems importing some needed library for handling some kind of images (jpeg2000 and jbig2) needed by PDFbox.
Here is my pom (part of it)
...ANSWER
Answered 2017-May-02 at 08:49I was looking at the wrong issue! The problem was not in the JPEG2000/JBIG2 dependencies but in the javax.imageio.spi.ServiceRegistry which has a none issue with ServiceLoder in OSGi and is called from PDFBox. As here is described: OSGi java.Util.ServiceLoader
So i had to implement this solution. OSGi Aries spi-fly
