Simple color picker control for WPF

ColorPickerWPF

A simple WPF color picker control for .NET 4.5.2 licensed under MIT. Contains two color gradient images to sample from, and custom palette support.

You can invoke it as a dialog using:

Color color;

bool ok = ColorPickerWindow.ShowDialog(out color);

Or use the user control itself in your application: ColorPickerWPF.ColorPickerControl

The user can define their own palette by selecting a color and ctrl+clicking a swatch in the custom colors section (lower right).

The custom palette can be saved to an XML file in the application folder or loaded from the same.

The dialog won't load the custom palette automatically by default, but you can tell it to with the optional flags to ColorPickerWindow.ShowDialog([...], ColorPickerDialogOptions flags, string customPaletteName)

You can specify to show the simple (collapsed) view with flags = ColorPickerDialogOptions.SimpleView

Or you can load the default palette file (specified in the app.config setting DefaultColorPaletteFilename) with flags = ColorPickerDialogOptions.LoadCustomPalette.

Or both using flags = ColorPickerDialogOptions.SimpleView | ColorPickerDialogOptions.LoadCustomPalette

Finally, you can specify a palette filename to load instead of the default with the final optional argument string customPaletteName

An example showing the simple view and loading a custom palette file:

ColorPickerWindow.ShowDialog(out color, ColorPickerDialogOptions.SimpleView | ColorPickerDialogOptions.LoadCustomPalette, "MyPalette.xml");

This would show the dialog in simple view, and load the palette file "MyPalette.xml".

If you are using the ColorPickerControl instead of the dialog, you can load custom palettes with: LoadDefaultCustomPalette() or LoadCustomPalette(string filename).

The palette file, default "ColorPalette.xml", contains both the custom palette colors and the inbuilt colors. You can create your own inbuilt palette if you create an instance of ColorPickerWPF.Code.ColorPalette, populate its data accordingly, and save to file using ColorPalette.SaveToXml(string filename). You can then distribute your application with this custom palette file.

Unfortunately there is no mechanism for customizing the color gradient sample images at this time, or indeed any other customization. If you require further customization I recommend cloning the repo and adding ColorPickerWPF to your solution.

colorpickerwpf's Issues

Eyedropper color picker should be must have!

Presently there is no option to do color pick but only to select color.

What .net or assemblies does this target/require?

I have a WPF .net 4.5.2 project and I get errors when trying to add this package:

Could not install package 'ColorPickerWPF 1.0.6'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

Set initial color?

It would be nice if the initial selected color could be set when the dialog is invoked. Perhaps another argument, or use the value of the 'out color' arg?

Thanks for the handy control!

Support .NET 4?

Title says it all. We sometimes have reasons to be on older framework. Like application support for Windows XP(my mum uses it for work reasons)

Update Color in the UI, how?

so since the control cant really bind to a viewmodel property on its own Color Property i tried to use the SetColor method of the control but this doesnt seem to update the Control in the UI. I tried UpdateLayout() method too but still no refected change in the UI.

So question is how to propagate a value set in code to the UI? An example would be helpful here :)
