Another article in my C# image dithering mini-series, this time covering the Burkes error diffusion algorithm.

In my previous introductory post, I briefly described the concept of dithering an image. In this article, I will describe how to dither an image in C# using the Floyd–Steinberg algorithm.
For some time now, I've started moving away from monolithic and complex GUI tools in favour of more streamlined command line interfaces. While Spriter is a fairly competent product in its own right, for some jobs it is just overkill and so this simple tool (with source available) was created.
We use batch files for... well, pretty much everything. From simple files that simple optimize modified graphics, to the tendril-like files that build our software. For some time now, I've been using
cecho.exe from a CodeProject article so that I highlight errors and successes. Sadly this tool doesn't output anything if a console window isn't in use (for example from a CI server) and so I created a quick C# version for a direct replacement.
ColorGrid control is a fairly useful control for selecting from a predefined list of colours. However, it can take up quite a bit of screen real estate depending on how many colours it contains. This article describes how you can host a
ColorGrid in a standard
ToolStrip control, providing access to both the
ColorGrid and the
ColorPickerDialog, with some custom painting to show the active colour on the button to round it off.
I was recently using a
ComboBox control with the
DropDownStyle set to
Simple, effectively turning into a combined text box and list box.
However, when I wanted an action to occur on double clicking an item in the list I found that the control doesn't actually offer double click support. I suppose I should have just ripped out the combo box at that point and went with dedicated controls but instead I decided to extend
ComboBox to support double clicks.
In my last post, I described how to drag and drop items to reorder a
ListView control. This time I'm going to describe the exact same technique, but this time for the more humble
I can't remember when it was I first saw something being dragged with an insertion mark for guidance. Whenever it was, it was a long long time ago and I'm just catching up now.
This article describes how to extend a
ListView control to allow the items within it to be reordered, using insertion guides.
This control annoys me in myriad ways, but it does get the job done. One of the things that occasionally frustrates me is that by default it is essentially an embedded version of Internet Explorer 7 - or enabling Compatibility Mode in a modern IE session. Not so good as more and more sites use HTML5 and other goodies.
This article provides a helper class to easily set the browser emulation version from your C# applications.
A brief article which describes how to create a definition ruleset to allow better Batch/Command style formatting in the DigitalRune/SharpDevelop Text Editor control.
