Hi All,
As I know that the tiff contain header information, I can use one software
called tifftags.exe to get tiff tag information. However, I can't get any
reference from vb.net to do such feature. Please advise..
Thanks.

And so you would have your code create a file object, open your tiff file
and manually evaluate each byte
At the front there should be patterns, whatever they are, FF, AA, 55, FF,
then file attributes, a checksum, other info, the tiff data and some footer
(end of file info)
Write out on paper how you want to validate a tiff file, then create
variable names to associate to your tag information use the Switch statement
to parse, and then test it.
Uh oh, this sounds interesting. If there is a built in method? Im not aware
of it

Some tiff tags like height, width, colour depth and so on are decoded into
the standard image parameters. Other tags are provided as PropertyItems. The
GDI+ FAQ has a demo program that explains how to extract the property items
from an image and display their content.

If all else fails, you could always write your own identifier. Specs on
the format can be found on the web, i.e.: http://www.wotsit.org/

hi all,
my problem is to get a tiff-file-attachment out of an email sent by a

hi ng,
I have a question concerning image processing in .NET: How can I open a jpeg
with a tiff-header in c# (which means the file has the extension .tif, but
contains jpeg-compressed data)? When I try to open the image the usual way,
e.g.: Image img = Image.FromFile("thefilename.tif"), I get an error ("not
enough memory"). This meaningful error message always comes up when .NET
cannot deal with the Image format I think...

I can seem to get the dimensions of a frame in a multiframe tiff.
After selecting activeframe, the Width/Height is still really much larger
than the page's actual dimensions.
When I split a TIFF to several PNG files this causes a problem, becuase the
resulting image is (the page to the far left and a lot of black space
surrounding it and a filesize that is larger than needed.
Any ideas?

Is there an easy way to create a tiff header? I have an old legacy
system that provides the binary image data separate from the actual
image parameters (resolution, bpp, etc.). So, i need to combine all
that information into one image. The image data by itself will not load
into the Image class, since it can't recognize it yet.
I have the tiff 6.0 specification, but i was looking for something a
little easier and quicker.
thanks,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
