One of our internal tools eschews XML or JSON configuration files in favour of something more human readable - YAML using YamlDotNet. For the most part the serialisation and deserialisation of YAML documents in .NET objects is as straight forward as using libraries such as JSON.net but when I was working on some basic serialisation there were a few issues. This article describes how to use the
IYamlTypeConverter interface to handle custom YAML serialisation functionality.
A short follow up which demonstrates how to write a RIFF palette with ease.
At the start of 2014, I published an article describing how to read colour palettes from BBM/LBM files. At the end of that article I noted that Microsoft palette files used a similar format, but I didn't investigate that at the time. Since then I followed up with articles on reading and writing Adobe's Color Swatch and Color Exchange format files and I posted code for working with JASC, Gimp and other palette formats.
Now, finally, I decided to complete the collection and present an article on reading Microsoft's palette files.
I've recently been updating our series on dithering to include ordered dithering. However, in order to fully demonstrate this I also updated the sample to include basic color quantizing with a fixed palette.
While color reduction and dithering are related, I didn't want to cover both topics in a single blog post, therefore this post covers finding the nearest color via Euclidean distance.
A short article on at least one possible cause for the very unhelpful

A brief article showing how to display individual pages from a multi-page tiff file in the ImageBox control.
One of the nice things about the Visual Studio WinForms designers are the guidelines it draws onto design surfaces, aiding you in perfectly positioning your controls. These guidelines are known internally as snap lines, and by default each visual component inheriting from
Control gets four of these, representing the values of the control's
Margin property. However, this default designer doesn't include an implementation for the
BaseLine snap line, which is used to align controls via their contained text. This article shows how to create a custom designer to allow your controls to easily include this alignment option.
In several of my applications, I need to be able to line up text, be it blocks of text using different fonts, or text containers of differing heights. As far as I'm aware, there isn't a way of doing this natively in .NET, however with a little platform invoke we can get the information we need to do it ourselves as this short article demonstrates.
Some weeks ago I was trying to make parts of WebCopy's UI a little bit simpler via the expedient of hiding some of the more advanced (and consequently less used) options. And to do this, I created a basic toggle panel control. This worked rather nicely, and while writing it I thought I'd write a short article on adding keyboard support to WinForm controls.
One of the things that frequently annoys me about third party controls (including those built into the .NET Framework) are properties that either aren't
virtual, or don't have corresponding change events / virtual methods. Quite often I find myself wanting to perform an action when a property is changed, and if neither of those are present I end up having to create a custom version of the property, and as a rule, I don't like using the
new keyword unless there is no other alternative.
As a result of this, whenever I add properties to my WinForm controls, I tend to ensure they have a change event, and most often they are also virtual as I have a custom code snippet to build the boilerplate. That can mean some controls have an awful lot of events, many of which are rarely used.
This article describes how you can explicitly implement events to reduce the amount of memory your types take.
