Bug ID: 60406
Summary: Image extensions getting altered.
Product: POI
Version: 3.15-FINAL
Hardware: PC
Status: NEW
Severity: major
Priority: P2
Component: XWPF
Assignee: dev@poi.apache.org

Target Milestone: ---
Created attachment 34468

Added the output snapshot which validates the bug.
Description:
============
I am using Apache POI library to extract images from a word(docx) file. The
issue that I am facing is regarding extension(image type) extraction and is
described as follows:
* I am getting wrong extension for images(embedded via insert object from
insert tab).
* When the image is embedded via drag and drop then the extension is
perfectly extracted
Steps to reproduce :
====================
1. Create a docx file with two images embedded to it.
a. Embed first image (assume it to be 1.jpeg) via (Insert Tab -> Insert
Object -> Create from file -> Add object).
b. Embed second image (assume it to be 2.png) via drag and dropping in the
word file.
2. Create a java program which accepts the file created and processes the file
and extracts the image file and shows the "image type" and "name" in the
console.
Expected Result:
=================
5 => //Document.PICTURE_TYPE_JPEG = 5
image1.jpeg
6 => //Document.PICTURE_TYPE_PNG = 6
image2.png
Current Result:
================
2 => //Document.PICTURE_TYPE_EMF = 2
image1.emf
6 => //Document.PICTURE_TYPE_PNG = 6
image2.png
Code used for extracting the image information:
================================================
InputStream content = null;
content = new BufferedInputStream(new FileInputStream(filePath));
XWPFDocument doc = new XWPFDocument(content);
List<XWPFPictureData> pics = doc.getAllPictures();
for(XWPFPictureData pic : pics)
{
System.out.println(pic.getPictureType());
System.out.println(pic.getFileName());
}
