[jira] [Commented] (PDFBOX-3359) Drawing to Graphics2D / ScratchFileBuffer not closed

Ivan Ridao Freitas commented on PDFBOX-3359:
I end up using this code to simulate a PDF preview with the current version
(2.0.1):
{code}
@Override
public void paintComponent(Graphics g) {
Graphics2D graphics = (Graphics2D) g.create();
bufferedImage = new BufferedImage(scaledWidth, scaledHeight,
BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = bufferedImage.createGraphics();
g2.addRenderingHints(hints);
g2.setColor(Color.WHITE);
g2.fillRect(0, 0, scaledWidth, scaledHeight);
g2.scale(scaleX, scaleY);
g2.clip(imageableArea);
try {
g2.setBackground(Color.WHITE);
// Margins
g2.translate(imageableArea.getX(),
imageableArea.getY());
renderer.renderPageToGraphics(pageNumber, graphics);
} catch(Exception e) {
e.printStackTrace();
}
g2.dispose();
graphics.drawImage(bufferedImage, null, 0, 0);
graphics.dispose();
}
{code}
I make the scaling before PDFBox rendering. I had to set
g2.setBackground(Color.WHITE); since the background is black by default (I
don't know if that is the expected behaviour for PDFBox). I also use a cache
and only re generate bufferedImage if the scale was changed, but I removed that
from the example code.

What about the debug messages?

Summary: Drawing to Graphics2D
Key: PDFBOX-3359
URL: https://issues.apache.org/jira/browse/PDFBOX-3359
Project: PDFBox
Issue Type: Bug
Affects Versions: 2.0.1
Reporter: Ivan Ridao Freitas
First, there is a little bug on PDFRenderer.renderPageToGraphics(int pageIndex,
Graphics2D graphics, float scale) when using scale != 1 the call to clearRect()
fill the original size with white background, but it should fill the scaled
size.
Second, I implemented a JPanel which is painted using that function and on
every paint this message goes to the console:
"DEBUG ScratchFileBuffer:516 - ScratchFileBuffer not closed!". Here is the code
to test it, run it and resize the JFrame:
{code:title=PanelTest.java|borderStyle=solid}
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.io.File;
import java.io.IOException;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import javax.swing.WindowConstants;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.rendering.PDFRenderer;
public class PanelTest {
private static JPanel getTestPanel() {
PDDocument doc = null;
try {
doc = PDDocument.load(new File("anyfile.pdf"));
} catch (IOException e) {
e.printStackTrace();
}
final PDFRenderer renderer = new PDFRenderer(doc);
JPanel panel = new JPanel() {
@Override
protected void paintComponent(Graphics g) {
try {
renderer.renderPageToGraphics(0, (Graphics2D) g, 0.5f);
} catch (IOException e) {
e.printStackTrace();
}
}
};
return panel;
}
public static void main(String[] args) throws Exception {
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(getTestPanel());
frame.pack();
frame.setSize(600, 400);
Dimension paneSize = frame.getSize();
Dimension screenSize = frame.getToolkit().getScreenSize();
frame.setLocation((screenSize.width - paneSize.width) / 2,
(screenSize.height - paneSize.height) / 2);
frame.setTitle("Test");
frame.setVisible(true);
}
});
}
}
{code}
