[jira] [Updated] (PDFBOX-2822) infinite loop of searching for a key
in PDResources
[ https://issues.apache.org/jira/browse/PDFBOX-2822?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Konstantin Kakunin updated PDFBOX-2822:
---------------------------------------
Description:
error in code of class - org.apache.pdfbox.pdmodel.PDResources
{code}
private COSName createKey(COSName kind, String prefix)
{
COSDictionary dict = (COSDictionary)resources.getDictionaryObject(kind);
if (dict == null)
{
return COSName.getPDFName(prefix + 1);
}
// find a unique key
String key;
do
{
key = prefix + (dict.keySet().size() + 1);
}
while (dict.containsKey(key)); <--------------- infinite loop of searching for a key
return COSName.getPDFName(key);
}
{code}
my test code:
{code}
public class pdfmain_svg {
public static void main(String[] args) throws Exception {
System.out.println("hello");
PDDocument document = PDDocument.load(new File(
"d:\\Project\\pdfbox-image\\Acro6JSGuide.pdf"));
float fontSize = 10f;
PDFont font = PDType0Font.load(document, new File(
"c:\\Windows\\Fonts\\Arial.TTF"));
for (int pageIndex = 0; pageIndex < document.getNumberOfPages(); pageIndex++) {
System.out.println("page index = " + pageIndex);
PDPage page = document.getPage(pageIndex);
PDPageContentStream contentStream = new PDPageContentStream(
document, page, true, true);
contentStream.setFont(font, fontSize); <---------------- hang on page 6
contentStream.setNonStrokingColor(Color.LIGHT_GRAY);
contentStream.beginText();
contentStream.newLineAtOffset(100, 100);
contentStream.showText("Test printing");
contentStream.endText();
contentStream.close();
}
File f = new File("d:\\work\\kostya.pdf");
document.save(f);
document.close();
System.out.println("f=" + f.getAbsolutePath() + ": " + f.exists());
}
}
{code}
