loading images

Previously, I asked this question in which my images in the jar file were not loading when using:

Image.getInstance("images/vblogowhite.gif");

Then Bruno and someone helped me and asked to use classloader, and it worked (see below) – so thanks

ClassLoader cl = this.getClass().getClassLoader();

URL vImgURL = cl.getResource("images/vblogowhite.gif");

Image verizGif= Image.getInstance(vImgURL);

The problem with the above approach is that we have to package those images in our jar file, which is not desirable. We want to avoid this (exploded is not an option either). Our webapp is packaged in separate war and it has to access the iText pdf report generation code (that also puts images on the document that is in jar file). The code in jar file is common and can be called from stand-alone and webapps.

Since number and type of images can change depending upon reports and customers, we want to load images in UI and pass to iText code (in jar) file as a File object as a parameter – like a file object and then create image out of it.

This would have advantage of not jarring the images in the jar file (they could reside in their place in webapps) as well as allowing users to load different images for different stuff. I looked at iText api for images and there is no method like:

Image.getInstance (File file).

A method like Image.getInstance (File fileObject) could prevent all the above, since UI will load image as file and pass to back-end code the file.

The back-end iText code can either do

Image img = Image.getInstance(File file) and do

Document.add(img)

There is Image.getInstance(String filename) and Image.getInstance(URL url) in API, but they would require class loader to load the images as well as packaging them in the jar file

We want to load the images as file from UI and pass to back-end as file object and then want to use something like

Image.getInstance (File file) to create images.

Kindly tell me if its possible and if there is a sample?

Thanks

Can you please post the question again WITHOUT

referring to previous answers and missing mails.

Phrase it as simple as possible, because I don't

understand what you want (and I doubt if anyone

on the list does).

The way I interpret it, you have an Image shown in

a Java UI (therefore it's probably a java.awt.Image)

and now you want this java.awt.Image to be in a PDF

file, for instance using Image.getInstance(java.awt.Image);

If that is the case, I don't understand why you are

asking. If that is not the case, you will have to

be more clear, because you are mostly telling what

you don't want, and that confuses me because I don't

always remember previous mail conversations. Start anew

with your question without all the irrelevant history.

Bruno
