PDFBox를 사용하여 응용 프로그램에 PDF 파일을 표시하고 있습니다. JScrollPane에 PdfPagePanel을 추가했습니다. 창을 더 작게 만들고 스크롤 막대가 나타나면 PageDrawer가 스크롤 막대에 그립니다.PDFBox - PageDrawer가 PdfPagePanel 외부로 그립니다.
이 효과는 PDFReader (PDFBox의 실행 가능 예제)에서도 발생합니다. pdf 파일 열기 -> 창 크기 줄이기 -> PDF- 콘텐츠 가져 오기가 스크롤 막대 위에 그려 짐
아무도이 문제를 해결할 방법을 알고 있습니까?
환경 : PDFBox 1.7.1, 윈도우 7, 자바 사전에 1.6.31
감사합니다, 샤샤
나는 아직도 1.8.1에서 같은 이상한 문제가 있습니다.
내 솔루션은이 같은 BufferedImage에 페이지를 변환하는 것입니다 :
이PDDocument document = PDDocument.load(new File("C:\\Temp\\stuff.pdf"));
List<PDPage> allPages = document.getDocumentCatalog().getAllPages();
PDPage firstPage = allPages.get(0);
BufferedImage bi = firstPage.convertToImage();
그리고 보통 인 JPanel를 작성하고 당신이 그것을 원하는대로 거기에 이미지를 표시 ...
내가이 도움이되기를 바랍니다. 이상한 문제! 행운을 빕니다!자르기 상자를 사용할 수 있습니다.
page.setCropBox(new PDRectangle(panel.getWidth(), panel.getHeight()));
있지만 당신이 매번 당신의 패널을 변경 크기를 자르기 상자를 설정해야합니다 의미합니다. 그리고 scrollpanes 제대로 작동하도록 가져올 수 없습니다.
PageDrawer의 작성자는 이전 클립 설정 (예 : 스윙)과 교차하지 않고 setClip()을 사용하고 있습니다. 그렇기 때문에 PageDrawer를 사용하여 창 오른쪽과 아래쪽에있는 다른 모든 요소를 덮어 쓸 수 있습니다. 나는 그래픽 대리자를 해결 방법으로 썼다.
PageDrawer drawer = new PageDrawer();
try
{
drawer.drawPage(new StrictClip(g2D), m_page, dim);
}
finally
{
drawer.dispose();
}
그리고 이제 StrictClip 클래스 자체 :이 도움이

희망은 그 방법을 사용하는 것이 꽤 긴하지만, 간단합니다.
감사합니다. 한글
