[jira] Created: (PDFBOX-616) Invalid Images Returned

Invalid Images Returned
-----------------------

                 Key: PDFBOX-616
                 URL: https://issues.apache.org/jira/browse/PDFBOX-616
             Project: PDFBox
          Issue Type: Bug
          Components: PDModel
    Affects Versions: 0.8.0-incubator
         Environment: Multiple (Windows)
            Reporter: James A. Thomas


When getting images from a PDF document using PDXObjectImage (code fragment below), it returns an image with invalid characteristics.  The PDXObjectImage is not null, but attributes like .getColorSpace() return null.  The image has a height and width, but the getRGBImage() method returns null.

This happens on EVERY image of the attached file.  Code fragment and output is shown below.  

Code Fragment:

                // Get a list of pages from the input PDF document
                List pages = InputDoc.getDocumentCatalog().getAllPages();
                // Process each page
                int i = 0;
                for (Object obj : pages)
                {
                    String Barcode = null;
                    i++;
                    PDPage page = (PDPage)obj;
                    // Get the image on the page and process it
                    PDResources resources = page.getResources();
                    Map images = resources.getImages();
                    System.out.println("Found " + images.size() + " images on Page " + i);
                    if( images != null )
                    {
                        Iterator imageIter = images.keySet().iterator();
                        while ( imageIter.hasNext() )
                        {
                            String key = (String)imageIter.next();
                            System.out.println("key = " + key);
                            PDXObjectImage image = (PDXObjectImage)images.get( key );
                            if (image != null)
                            {
                                System.out.println("Image subtype = " + image.SUB_TYPE.toString());
                                System.out.println("Image suffix = " + image.getSuffix());
                            System.out.println("PDX image has height = " + image.getHeight()
                                                + " and width " + image.getWidth());
                            // Convert image to a Buffered Image, so we can
                            // look for a barcode and decode it
                            BufferedImage RGBimage = image.getRGBImage();
                            if (RGBimage == null)
                                System.out.println("RGBimage is null");
                            }
                        }
                    }

Output:

[jira] Commented: (PDFBOX-616) Invalid Images Returned

James A. Thomas commented on PDFBOX-616:
----------------------------------------

Tom: This was most certainly the problem.  I added those libraries, and my code works fine now.  Thank you!  

Seems like this should be a comment somewhere in the PDFBox documentation?

[jira] Updated: (PDFBOX-616) Invalid Images Returned

Posted by "James A. Thomas (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/PDFBOX-616?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

James A. Thomas updated PDFBOX-616:
-----------------------------------

    Description: 
When getting images from a PDF document using PDXObjectImage (code fragment below), it returns an image with invalid characteristics.  The PDXObjectImage is not null, but attributes like .getColorSpace() return null.  The image has a height and width, but the getRGBImage() method returns null.

This happens on EVERY image of the attached file.  Code fragment and output is shown below.  

If I use the write2file() method of PDXObjectImage to write out the image to a fil, then I get a valid image.  (At least, it displays fine.)

Code Fragment:

                // Get a list of pages from the input PDF document
                List pages = InputDoc.getDocumentCatalog().getAllPages();
                // Process each page
                int i = 0;
                for (Object obj : pages)
                {
                    String Barcode = null;
                    i++;
                    PDPage page = (PDPage)obj;
                    // Get the image on the page and process it
                    PDResources resources = page.getResources();
                    Map images = resources.getImages();
                    System.out.println("Found " + images.size() + " images on Page " + i);
                    if( images != null )
                    {
                        Iterator imageIter = images.keySet().iterator();
                        while ( imageIter.hasNext() )
                        {
                            String key = (String)imageIter.next();
                            System.out.println("key = " + key);
                            PDXObjectImage image = (PDXObjectImage)images.get( key );
                            if (image != null)
                            {
                                System.out.println("Image subtype = " + image.SUB_TYPE.toString());
                                System.out.println("Image suffix = " + image.getSuffix());
                            System.out.println("PDX image has height = " + image.getHeight()
                                                + " and width " + image.getWidth());
                            // Convert image to a Buffered Image, so we can
                            // look for a barcode and decode it
                            BufferedImage RGBimage = image.getRGBImage();

  was:
When getting images from a PDF document using PDXObjectImage (code fragment below), it returns an image with invalid characteristics.  The PDXObjectImage is not null, but attributes like .getColorSpace() return null.  The image has a height and width, but the getRGBImage() method returns null.

This happens on EVERY image of the attached file.  Code fragment and output is shown below.  

Code Fragment:

                // Get a list of pages from the input PDF document
                List pages = InputDoc.getDocumentCatalog().getAllPages();
                // Process each page
                int i = 0;
                for (Object obj : pages)
                {
                    String Barcode = null;
                    i++;
                    PDPage page = (PDPage)obj;
                    // Get the image on the page and process it
                    PDResources resources = page.getResources();
                    Map images = resources.getImages();
                    System.out.println("Found " + images.size() + " images on Page " + i);
                    if( images != null )
                    {
                        Iterator imageIter = images.keySet().iterator();
                        while ( imageIter.hasNext() )
                        {
                            String key = (String)imageIter.next();
                            System.out.println("key = " + key);
                            PDXObjectImage image = (PDXObjectImage)images.get( key );
                            if (image != null)
                            {

                                System.out.println("Image suffix = " + image.getSuffix());
                            System.out.println("PDX image has height = " + image.getHeight()
                                                + " and width " + image.getWidth());
                            // Convert image to a Buffered Image, so we can
                            // look for a barcode and decode it
                            BufferedImage RGBimage = image.getRGBImage();
                            if (RGBimage == null)

[jira] Commented: (PDFBOX-616) Invalid Images Returned

Posted by "Tom (JIRA)" <ji...@apache.org>.
    [ https://issues.apache.org/jira/browse/PDFBOX-616?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835600#action_12835600 ] 

Tom commented on PDFBOX-616:
----------------------------

If you get the available image readers in ImageIO chances are high that TIFF is missing. Try adding jai_core (1.1.3) and jai_imageio (1.2) to the classpath.
