Trouble printing image
I'm adding an image to my page with the following code. It works
correctly, and the image displays fine. However, we are getting reports
from some IE users that the image will not print. It prints fine for
most IE users, but there are a handful who can't get it to print.
While I don't know the reason, I did notice that when you right-click
the image and "Save As...", it doesn't have a name. In IE, the Save As
dialog calls it "untitled.bmp" (in spite of it being a png) and in
Firefox it's "print.png". Perhaps this is the source of the issue? If
so, how do you give an image a name when you're adding it as a Resource?
(For anyone who's interested in looking, you can find the offending
image at http://foodhandler.org. Log in with username/password
"guest/guest". Then click the "Print Your Card" button on the navigation
bar. When you print the page, the only two images that should print are
the "Thawte 100% Secure" image at the top of the page and the card image
in the center of the page - the rest are turned off in a print
stylesheet.)
PrintPage.java:
public class PrintPage extends NavigationTemplate
{
public PrintPage()
{
Resource cardImage = getBothCardImageResource();
add(new NonCachingImage("bothCardImage", cardImage));
}
public Resource getBothCardImageResource()
{
final BufferedDynamicImageResource resource = new
BufferedDynamicImageResource();
BufferedImage image;
try {
image = ImageIO.read(((WebApplication)
Application.get()).getServletContext().getResourceAsStream("/path/to/MyI
mage.png"));
Graphics graphics = image.getGraphics();
... Do some stuff with the graphics ...
}
resource.setImage(image);
return resource;
}
}

I should have said that your class worked great for displaying the
image; it just didn't keep the image name. Well, time to study up on
Serkan's suggestion on Content-Disposition and see what that does.

Yeah, sorry about that. I think the FileUtils class is one of my own,
actually (from work or I'd just give it to you). I leave it up to the
reader to write the file copy method. :)

Thanks for the hint. I tried your class with some minor modifications
(see below -- I commented out two lines and used the Apache FileUtils,
since I'm not sure which FileUtils class your referenced) but without
any success. However, while playing with that, I did notice that
untitled.bmp that IE returns is 4+ MB, as compared to 200 KB for the
print.png that FireFox returns. I'm not sure what that means, but it
seems odd to me that the file returned would be browser-specific.
Thanks again,
Dane
Modified FileImageResource class:
public class FileImageResource extends DynamicImageResource
{
private static final long serialVersionUID = 1L;
private final String path;
public FileImageResource( File file, String format )
{
super(format);
this.path = file.getAbsolutePath();
//setCacheable(true);
//setLastModifiedTime(Time.valueOf(file.lastModified()));
}
protected byte[] getImageData()
{
try {
return FileUtils.readFileToByteArray(new
File(path));
} catch (IOException ioe) {
logger.error("Trouble reading the image file.",
ioe);
return null;
}
}
}

This ended up working for Firefox, but not for IE. The image served in
Firefox will Save As "x.png", but the image in IE still shows as
"untitled.bmp". Thanks for the suggestion though, it at least taught me
a lot about resources and setting headers :)

while serving the image resource, setting the Content-Disposition http
header
to
inline; filename=x.png
might help, but this is just a guess..
