I'm building a viewer that will load faxes received by a fax server.
Multipage faxes are saved as multipage tiffs. Is there some way to
handle this in SWT?
I need to alert the user if there is more than one page.
I need to be able to display the different pages.
I need to be able to delete individual pages.
I understand this may be beyond the scope of SWT, and if so, I'll use
ImageMagick to convert the tiffs to jpgs, which will separate the
multipage tiffs into individual jpgs.
However, if there is some way to do this in SWT, it would save me a
considerable amount of complexity.
Thanks,

Thanks very much for your response. As I said, I realize that is out of
scope for SWT, but I'll enter a feature request.
Thanks,

You can use the JAI (Java Advanced Imaging) Libraries from Sun.

Perhaps this code snippet will help you.
ArrayList images =3D new ArrayList();
File file =3D new File("C:\\test.tiff");
SeekableStream s =3D new FileSeekableStream(file);
TIFFDecodeParam param =3D null;
ImageDecoder dec =3D ImageCodec.createImageDecoder("tiff", s, param);
imageCount =3D dec.getNumPages();
String formatName =3D "JPG";
for (int i =3D 0; i < imageCount; i++) {
RenderedImage ri =3D dec.decodeAsRenderedImage(i);
ByteArrayOutputStream out =3D new ByteArrayOutputStream();
boolean writerExists =3D ImageIO.write(ri, formatName, out);
if (!writerExists) {
throw new IOException("Illegal ImageFormat: " + formatName);
}
ByteArrayInputStream in =3D new ByteArrayInputStream(out.toByteArray()=
);
images.add(new Image(parent.getDisplay(), in));
}
