Extracting Images From PDF file

For extracting the images from a pdf file, i propose this solution. We are achieving this using PDFBox API.

The PDFBox-0.7.3.jar should be added to the classpath before executing the code.

The method extractImagesFromPDF() has two arguements:
pdfFileName - The complete path of the pdf file from which the images need to be extracted. Ex: C:/test_image.pdf
imagePath - The complete path where the extracted images needs to be stored as .jpeg file. Ex: C:/test/

If the pdf contain list of images, all the images will be extracted and stored as .jpeg files in the given output location. The images will be stored as image1.jpeg, image2.jpeg etc. This can be customized as per the project requirements.

Attached the ImageExtractionFromPDF.zip file which contains sample java program. This can be executed from the command prompt using the following command:
java ImageExtraction <pdfFile complete path> <Path where the extarcted images should be stored>
Ex:
java ImageExtraction C:/sample.pdf C:/test/
Note:
Before executing the java program, PDFBox-0.7.3.jar should be set to the classpath.

Limitations:
Images with standard image format(.jpeg, .jpg, .tiff etc) can be extracted from pdf. Special or proparatory image format cannot be extracted
