There is a class called AnimationInfo which supposed to give animation information from Presentation. But my bad luck I could not get it.
List<XSLFShape> shapes = slide.getShapes();
for (XSLFShape shape: shapes) {
//Need to get animation of this shape here
}
Can anyone help me on this ? Thanks.
PS: I am using 3.17 version of POI.
Given the addition of only detecting an animation, a sheet can be checked for a timing information which quite likely identifies the existence of an animation, i.e. you could get a false positive in case an animation was added and then removed again. Furthermore you need to check all slides, until an animation is found.

at the moment I evaluate some libraries for PDF creations in Java. PDFBox is at the moment one of the libraries I want to use. In my use case I want to give every chapter a new line numbering. I tried and searched a lot around, but I really have no idea how I can archieve this. Does anyone has some suggestions? Thank you very much for everything!
Maybe it will help. Here's how to generate a menu and sub-menu (along with main menu and sub-menu numbering):
Use this class:
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.pdmodel.PDPage;
import org.apache.pdfbox.pdmodel.PDPageContentStream;
import org.apache.pdfbox.pdmodel.font.PDFont;
import org.apache.pdfbox.pdmodel.font.PDType1Font;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.HashMap;
public class PdfExample
{
private String pdfFileName = "";
public PdfExample(String pdfFileName)
{
this.pdfFileName=pdfFileName;
//creating new document:
PDDocument document = new PDDocument();
PDPage blancPage = new PDPage();
document.addPage(blancPage);
PDFont font_TIMES_ROMAN = PDType1Font.TIMES_ROMAN;
try
{
PDPageContentStream fileStream = new PDPageContentStream(document,blancPage);
fileStream.setFont( font_TIMES_ROMAN, 12 );
fileStream.beginText();
fileStream.newLineAtOffset(50,735);
fileStream.showText("Chapter numbering example:");
fileStream.endText();
//veeery simple positioning configuration:
int mainMenuPosition_Y = 700;
int mainMenuPosition_X = 50;
int lineSpacing = 30;
int numberOfMainMenus = 6;
int subMenuLeftMargin = mainMenuPosition_X+20;
HashMap<Integer, ArrayList> subMenu = new HashMap<Integer,ArrayList>();
//I'm adding some sample submenu's:
subMenu.put(1,new ArrayList<String>(Arrays.asList("Item 1","Item 2","Item 3"))); // firstOne Main Menu
subMenu.put(2,new ArrayList<String>(Arrays.asList("Item 1","Item 2","Item 3"))); // second Main Menu
subMenu.put(5,new ArrayList<String>(Arrays.asList("Item 1","Item 2"))); // 5th
for(int i = 1 ; i <= numberOfMainMenus ; i++)
{
fileStream.beginText();
fileStream.newLineAtOffset(mainMenuPosition_X,mainMenuPosition_Y);
fileStream.showText(i+". Main Menu");
fileStream.endText();
if(subMenu.get(i)!=null)
{
for(int w = 0; w < subMenu.get(i).size();w++)
{
System.out.println(subMenu.get(i).get(w));
fileStream.beginText();
fileStream.newLineAtOffset(subMenuLeftMargin,(mainMenuPosition_Y-=15));
fileStream.showText(i+"."+(w+1)+" "+subMenu.get(i).get(w));
fileStream.endText();
}
}
mainMenuPosition_Y-=lineSpacing;
}
fileStream.close();
document.save(pdfFileName+".pdf");
document.close();
}
catch (IOException e)
{
e.printStackTrace();
}
}//end
}
and then just:
PdfExample document = new PdfExample("SimpleExample");
This code will generate something like this:
SimpleExample

I have gradle script which is creating the version in JIRA using the REST API.

I'm trying to extract establishments data from GooglePlaces API. It used to work initially, but after making a specific method for extracting the places (instead of in the main method), the program crushes. When debbuged it, it gets stuck in a java method called park (under LockSupport class from java). Reading about it, it says that this happens when there is more than 1 thread and there are sync problems. I'm very new at this and I don't know how to solve this in my code. In my mind, there is only 1 thread in this code, but I'm pretty sure I'm wrong. Please help. It crashes in a "for" commented below. Thanks so much!

Why do I get an OutOfMemoryError? I tryed it with an other Dedector and there it works?! I also looked in some other Questions for an Answer and i found one Solution and i excactly worked with it, but it also didn't worked.
It's my first time working with Openimaj.

The reason you got failed is because of image processing algorithm used. I'm not sure what openimaj uses, but there are two workarounds possible for this:
Increase heap size, so that your application has more memory available for image processing. See How can I increase the JVM memory?
Decrease image size, so that your application will use less memory for processing.
Based on my own experience with face detection on mobile devices (limited memory as well), 940x720 seems to be more than enough for face detection. Feel free to resize into 640x480 (or similar), results should not be affected.
Remember that you can copy your initial image, resize it with any aspect ratio (i.g. 1.5), detect face on new resized image and return initial image with detected face coordinates multiplied on your aspect ratio.
I want to do some image analysis on a video that's stored in .mp4 format. Therefore I need a way to just get the images of this movie in Java.
I goolged a lot and found some libraries like jcodec and jaad. BUT I wasn't able to get the things running with these libraries. And as I found out, there were examples (at least I found none) that showed my usecase.
Can you help me? Do you know any library that can do what I need and is running at least on Win7 64 bit.
Or do you know how to accomplish this with jcodec?
edit:
As I wrote, I tried it with jcodec. I found out how to get the data of a frame, but not how I can get it into something like a BufferedImage or so. I expect that these data isn't in a simple RGB format but in any compressed format or so. (Am I right with that?) I don't know to to decode this data.
You can get the data of a frame with jcodec as follows (at least as far as I understand this):
public static void main(String[] args) throws IOException, MP4DemuxerException {
String path = "videos/video-2011-09-21-20-07-21.mp4";
MP4Demuxer demuxer1 = new MP4Demuxer(new FileInput(new File(path)));
DemuxerTrack videoTrack = demuxer1.getVideoTrack();
Packet firstFrame = videoTrack.getFrames(1);
byte[] data = firstFrame.getData();
}
I also found the following:
http://code.google.com/p/jcodec/source/browse/trunk/src/test/java/org/jcodec/containers/mp4/DitherTest.java?r=70
But this isn't working (has compile errors) with the downloadable jar-package.
you could use jcodec(https://github.com/jcodec/jcodec) in the followinf program i am extracting frames from a video.
