Key: PDFBOX-3573
URL: https://issues.apache.org/jira/browse/PDFBOX-3573
Project: PDFBox
Issue Type: Bug
Components: Parsing, Utilities
Affects Versions: 2.0.3
Environment: Ubuntu 15.10
Reporter: Dmitri Russu
I try to get Images from an PDF file, file pages are images, total size of PDF
file is about 1MB
Code I run is next
public static void testExtractImages() throws Exception {
File resource = new File("test/t1_edited.pdf");
PDDocument document = PDDocument.load(resource);
int page = 1;
for (final PDPage pdPage : document.getPages())
{
final int currentPage = page;
PDFGraphicsStreamEngine pdfGraphicsStreamEngine = new
PDFGraphicsStreamEngine(pdPage)
{
int index = 0;
@Override
public void drawImage(PDImage pdImage) throws
IOException
{
if (pdImage instanceof PDImageXObject)
{
PDImageXObject image =
(PDImageXObject)pdImage;
File file = new File("test/",
String.format("10948-new-engine-%s-%s.%s", currentPage, index,
image.getSuffix()));
ImageIOUtil.writeImage(image.getImage(), image.getSuffix(), new
FileOutputStream(file));
index++;
}
}
@Override
public void appendRectangle(Point2D p0, Point2D
p1, Point2D p2, Point2D p3) throws IOException { }
@Override
public void clip(int windingRule) throws
IOException { }
@Override
public void moveTo(float x, float y) throws
IOException { }
@Override
public void lineTo(float x, float y) throws
IOException { }
@Override
public void curveTo(float x1, float y1, float
x2, float y2, float x3, float y3) throws IOException { }
@Override
public Point2D getCurrentPoint() throws
IOException { return null; }
@Override
public void closePath() throws IOException { }
@Override
