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.ti f"), I get an error ("not
enough memory"). This meaningful error message always comes up when .NET
cannot deal with the Image format I think...
Thanks,
Albert 7 4721
So it is a TIFF or a JPEG?
The internal file structure of them two is totally different.

Well, that's the tricky thing about it...it is a tif-file (with tif-header
and all that stuff, but it contains jpeg compressed image data, e.g.
Irfanview calls this Compression "Old JPEG (in TIFF)"). We get images of
that kind from our Kodak i260 scanner :-)

What are you intending to do with the image once it is loaded?

Just a guess, but you'll probably have to load the relevant JPEG data
into a Stream and then use the Image.FromStrea m method to load it into
an Image object.
Thanks a lot, yes that could work I think...but isn't it a strange thing
that one has to go so deep into the image to read it's content? Again: our
Kodak-Scanner writes this format by default!

Yes, images are strange. I've messed around with a few different
formats including icons and none of it is straight forward to me. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I'm using the System.Drawing.Image name space to convert images from

The code almost always seems to work, but some times I receive the

Hope it's not inappropriate to post this here.
Could someone critique my code? I have no Python programmers in my
office to show this to. The script works OK, but should I do it
differently? I especially don't like how I check to see if jpegs exist.
The style may not be acceptable to some, but I'm concerned with
substance, not style. Is there a 'more appropriate' way to do this?
Thanks to all who take the time to give advice!

upper and lower significant bits of the value to see the compression.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
