All Users: Check to See If You Have the .NET Framework Installed

You can check to see if you already have the .NET Framework 1.1 installed by clicking Start on your Windows desktop, selecting Control Panel, and then double-clicking the Add or Remove Programs icon. When that window appears, scroll through the list of applications. If you see Microsoft .NET Framework 1.1 listed, the latest version is already installed and you do not need to install it again.

Note: Non-developers need to install the .NET Framework 1.1 to run applications developed using the .NET Framework 1.1.

In most cases, the creator of an application will alert you if you need to install the .NET Framework 1.1 Redistributable to run the application.

:siren: You need to install the .NET Framework 1.1 Redistributable to run the application. :siren:

However, with the number of .NET Framework-connected applications on the market growing rapidly, we encourage you to install the latest version of the .NET Framework 1.1 Redistributable if you haven’t already.

General Users: Install Through Windows Update

If you only want to run applications built using the .NET Framework 1.1, download the .NET Framework 1.1 from Microsoft Windows Update.


You know how on the old site the example output for the program were all resized and processed in another program? Well, I’ll never have to do that again. Here’s some more samples, once again actual untouched output but this time the output image has first been resized to 75% by the program. Click:

I need to work out a nice interface to do it (possibly on a new dialog?), but it didn’t take much code and worked far better then I hoped.


  • Calculating accurate width and height for a font – done*
  • Save as an image – basic saving done (will eventually be able output a resized image in the program)
  • Register sourceforge project – done

* - In C++Builder I just needed to call a function, literally one line of code. In dotNET after several days of experimenting, I eventually managed it by wrapping several API functions. Sometimes I wonder why I switched.


Moved the Stretch/Sharpen/Unsharp mask options onto the tab with the output text and – get this – it now works in real time. I.e. uncheck the Sharpen option, and you’ll instantly see the output image without sharpening applied. It’s pretty sexy.

Also, playing around with the unsharp mask and blurring multiple times seems to improve the output a lot. I’m still trying to work out just how many times is best (maybe have that as an option…?)


The problem with the new conversion code has been fixed and the output is looking very nice. If I could have found it before spending several days porting the original code it would have been even better.

Finished the code to apply 3×3 convolution matrices to the output image, and replaced the old sharpening code with a matrix. Eventually the user will be able to enter a custom matrix to be used (i.e. for blurring/alternate sharpening/edge detection/mean removal etc). I’ve also got an unsharpening mask working, but it’s a little disappointing (2xoriginal – blurred, right?).

Aside from that, there’s lots of little things done that are hardly worth mentioning (drag drop image onto the form/executable, resizeable form so you can go full screen or use it in 800×600 mode, validation…)
