Hi all !
I have a multi-page Tiff image file that I want to convert to PDF. To do so
I am using iText library. The conversion is working, but the code execution
is very different according to wich
iTextSharp.text.Image.getInstance(...) signature I am using :
- using code 1 below, the conversion is fast enough but the resulting PDF
file is too big (1 817ko sample Tiff file is converted in less than 30
seconds to a 2 764ko PDF file)
-...

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...
Thanks,

Hi.
Why can't I read TIFFs compressed by JPEG using GDI+ Image class? I always
get out of memory exception.
Thanx.

I've seen once program which was able to convert any url to JPG file.
Once I tried it on cnn.com website and it created the nice jpg, even that
the page was scrollable, so it was not using printscreen or anything like
that.
Any idea how these things get done?

I need to take a large Tiff file composed of several scanned pages and
convert it to several individual Jpegs. I guess I will have to write a
component myself, doing the conversion on the byte level, but first I need a
map of the byte layout for a Tiff file and the algorithm to do the
conversion (or convert to BMP first if necessary). Can anyone here point me
in the right direction?
This might not be the best place to ask, if anyone can...

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!

Hey guys,
As part of a college project I'm trying to write a script to convert
TIFF images downloaded from the US patent office site, www.uspto.gov.
The tiff images are encoded using CCITT Group 4 compression and appear
to throw an error when i try to save them using the Image library:
>>> im.save(outfile, "PDF)

Hello, we have an app that scans documents into TIFF format and we
need to transfer them over the internet. If anyone knows of a SDK we
can use that can compress TIFFs on the fly or even if it can compress
them so they take up less space on the server, would be appreciated.
Actually any info on handling tiff files programatically would be
appreciated as I know very little about tiffs.
TIA

Hello folks,
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.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
