Can't get images from a PDF
---------------------------
Key: PDFBOX-1075
URL: https://issues.apache.org/jira/browse/PDFBOX-1075
Project: PDFBox
Issue Type: Bug
Components: Parsing
Affects Versions: 1.6.0, 1.7.0
Reporter: Antoni Mylka
Fix For: 1.4.0
This is a regression. In 1.4.0 I was able to extract images from a PDF file. In
1.6 and the current trunk I get exceptions:
SEVERE: java.lang.IllegalArgumentException: Raster BytePackedRaster: width =
1000 height = 32 #channels 1 xOff = 0 yOff = 0 is incompatible with ColorModel
IndexColorModel: #pixelBits = 1 numComponents = 3 color space =
java.awt.color.ICC_ColorSpace@1050169 transparency = 1 transIndex = -1 has
alpha = false isAlphaPre = false

I pasted it into the src/test/resources/pdfparser folder and run a test case
like this:
public class TestGovdocs148902 extends TestCase
{
public void test148902() throws IOException {
PDDocument doc = PDDocument.load(
"src/test/resources/pdfparser/148902.pdf");
int imageCounter = 0;
COSDocument cosDoc = doc.getDocument();
List<COSObject> list = cosDoc.getObjectsByType(COSName.XOBJECT);
for (COSObject cosOb : list) {
COSBase baseObject = cosOb.getObject();
if (baseObject != null && baseObject instanceof COSStream) {
COSStream st = (COSStream)baseObject;
String subtype = st.getNameAsString(COSName.SUBTYPE);
if (subtype != null && subtype.equalsIgnoreCase("image")) {
PDXObjectImage ximage =
(PDXObjectImage)PDXObject.createXObject( st );
if (ximage != null && ximage.getWidth() >= 5 &&
ximage.getHeight() >= 5) {
ByteArrayOutputStream baos = new
ByteArrayOutputStream();
ximage.write2OutputStream(baos);
byte [] bytes = baos.toByteArray();
if (bytes.length > 0) {
imageCounter++;
}
}
}
}
}
assertEquals(32, imageCounter);
}
}
The test cases passes in 1.4.
