Subject Image rendering in a .NET Web Service

I have a design dilemma here and I’m looking for suggestions. My
requirements pretty much dictate I have to build a Windows Service (program
needs to be running all the time), and I’ve chosen a Web Service specifically
with both a Windows Forms or WPF client and also a Silverlight web client.

For the sake of brevity, suffice to say that I need to render images within
this service process to be consumed by the clients. The problem is, if you
use System.Drawing or System.Drawing. Imaging (that’s where Bitmap and Image
are), you end up pulling GDI+ into the service process. MSDN documentation
makes it pretty clear that Microsoft does not want me doing this:
http://msdn.microsoft.com/en-us/libr...m.drawing.aspx

I made a little .NET test service which uses a third-party product to render
a chart over and over and writes it to a PNG file and that seems to work
fine. Process Explorer confirms GDI+ is indeed loaded in the process. My
question is this: Will this very basic use of GDI+ in a Windows Service
cause any real problems? Any thoughts on a way out of this?

Thanks for any input.

I'm developing an application that draws on several disk based images to create a composite image. I've noticed that my rendering time goes up as I load more images into memory. However, this seems to be due to the number of distinct images rather than the number of bytes they take up, since when I combine them into a single image in photoshop my rendering time goes down again. Since an image is essentially a 1D array of bytes in...

Hi, I am currently writing a news admin system. I would like to add the ability to add images to each article. What I have always done in the past is uploaded (using a form) the image to a folder on the server and then in the database table that I INSERT the news article, I'll store the path of the uploaded image. To me this seems a bad idea as if the image paths were changed on the

Hello all, A question relating to http://www.entrust-systems.net/ Just for a change I have run into a problem that seems to be OS specific rather than browser specific - the box image that is acting as a faux border for the main text block shows nasty image effects on the outside when using either Firefox or Konqueror on Suse Linux. This image is set to resize with the browser window (and hence the text) and this seems to be what...

Overview: 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,...
