-----------------------------------------
Here's an example derived from code in PDFBOX-3359:
{code}
protected void paintComponent(Graphics g)
{
try
{
g.setColor(Color.red);
g.fillRect(0, 0, getWidth(), getHeight());
PDPage page = doc.getPage(0);
PDRectangle cropBox = page.getCropBox();
boolean rot = false;
if (page.getRotation() == 90 || page.getRotation() == 270)
{
rot = true;
}
//

float imgWidth = rot ? cropBox.getHeight() :
cropBox.getWidth();
float imgHeight = rot ? cropBox.getWidth() :
cropBox.getHeight();
float xf = getWidth() / imgWidth;
float yf = getHeight() / imgHeight;
float scale = Math.min(xf, yf);
if (yf < xf)
{
g.translate((int) ((getWidth() - imgWidth * yf) / 2),
0);
}
else
{
g.translate(0, (int) ((getHeight() - imgHeight * xf) /
2));
}
renderer.renderPageToGraphics(pageNum-1, (Graphics2D) g,
scale);
}
catch (IOException e)
{
e.printStackTrace();
}
}
