RE: Trouble printing image
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 :) Dane -Original Message- From: Serkan Camurcuoglu [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 14, 2008 12:25 PM To: users@wicket.apache.org Subject: Re: Trouble printing image while serving the image resource, setting the Content-Disposition http header to inline; filename=x.png might help, but this is just a guess.. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

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

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

Resource cardImage = getBothCardImageResource();
add(new NonCachingImage(bothCardImage, cardImage));

public Resource getBothCardImageResource()

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

RE: Trouble printing image
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;
}
}
}

Re: Trouble printing image
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. :)

RE: Trouble printing image
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. -Original Message- From: James Carman [mailto:[EMAIL PROTECTED] Sent: Tuesday, October 14, 2008 2:31 PM To: users@wicket.apache.org Subject: Re: Trouble printing image Yeah, sorry about that.
