Mask is not applied.
The attached pdf is the first page referred to in this link from Gunnar Brand.
https://www.mail-archive.com/users@pdfbox.apache.org/msg11980.html
When I render this page in pdfbox 2.0.24 I get a blank page using code
similar to below, which works for documents which are not using masks.
PDDocument document = PDDocument.load(fileAsByteArray)
PDFRenderer renderer = new PDFRenderer(document);
// configuring renderer for best image
RenderingHints hints = new RenderingHints(null);
hints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_SPEED);
hints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_OFF);
hints.put(RenderingHints.KEY_STROKE_CONTROL, RenderingHints.VALUE_STROKE_PURE);
renderer.setRenderingHints(hints);
// render relevant the pages into memory
BufferedImage bufferedImage = renderer.renderImage(0, 5, ImageType.BINARY);
I have tried with/without the hints and with different scales and image types.
Any ideas what's going wrong here?
Thanks.

I can't help on Intelli and on gradle. You need to make sure that the
jar files are in your class path. (And update pdfbox and log4j!)
Re log4j2, here's the file I use locally:
<?xml version="1.0" encoding="UTF-8"?>

Hi Tilman
The jbig and j2k stuff got removed from the gradle files. Oops! Thanks for
that.
The next problem is that I get the mask image applied when I run in
IntellIj in debug mode, but not when run compiled using the same gradle
settings.
*build.gradle*
implementation 'org.apache.logging.log4j:log4j-api'
implementation 'org.apache.pdfbox:pdfbox'
implementation 'com.github.jai-imageio:jai-imageio-core'
implementation 'com.github.jai-imageio:jai-imageio-jpeg2000'
implementation 'org.apache.pdfbox:jbig2-imageio'
*dependencies-versions.gradle*
implementation "org.apache.logging.log4j:log4j-api:2.16.0"
implementation "org.apache.logging.log4j:log4j-core:2.16.0"
implementation "org.apache.pdfbox:pdfbox:2.0.24"
implementation "com.github.jai-imageio:jai-imageio-core:1.4.0"
implementation "com.github.jai-imageio:jai-imageio-jpeg2000:1.4.0"
implementation "org.apache.pdfbox:jbig2-imageio:3.0.3"
I have tried using runtimeClasspath instead of "implementation" but no
change.
I would like to set up the logging, but I do not understand from the
documentation how to do that. The module that instantiates the pdfBox
objects has the following log4j config:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" xmlns:xi="http://www.w3.org/2001/XInclude" >
<xi:include href="xincludes/log4j2-patterns.xml"/>
<Appenders>
<xi:include href="xincludes/log4j2-appender-console.xml"/>
<xi:include href="xincludes/log4j2-appender-file.xml"/>
</Appenders>
<Loggers>
<Root level="debug">
<AppenderRef ref="Console" level="debug" />
<AppenderRef ref="File" level="debug" />
</Root>
</Loggers>
</Configuration>
I get logging from our code but not from pdfBox, although when tracing I
can see that it is logging somewhere ...
Could you give me some advice?
Thanks again.

Are the JBIG2 and JPX plugins in your classpaths? Did you see any log
messages? Did you activate logging?
