I’ve uploaded a new version of this plugin on September 9, 2017. This version supports transparency in a proper way.

I’ve uploaded a new version of this plugin on 08-27-2017. This new version comes with a configuration file (“WicDecoder.ini”) which allows you to specify file extensions that should be ignored by this plug-in. Note: you have to restart Paint.NET after changing the configuration file of this plug-in.

Six years has passed since your request, but here you go:

Windows Imaging Component (WIC) Plugin This plugin adds reading support for all image formats that are supported by the Windows Imaging Component (WIC) codecs on your computer. On Windows 10 are by default the following formats supported by this plugin: .ARW, .BMP, .CR2, .CRW, .DIB, .DNG, .ERF, .GIF, .JPG, .KDC, .MRW, .NEF, .NRW, .ORF, .PEF, PNG, .RAF, .RAW, .RW2, .RWL, .SR2, .SRW, .TIF To improve the DNG support it’s recommended to install the following DNG codec from Adobe: DNGCodec_2_0_Installer.exe On Windows 7 you have to install the following codec pack to get support for the same formats: Microsoft Camera Codec Pack - http://www.microsoft.com/en-us/download/details.aspx?id=26829 Please note that raw files are automatically converted with the default parameters of the used codec. Use the excellent RAWFile plugin if you want to control the conversion of your images. Features The list of supported image formats (in the file open dialog) is based on the registered WIC codecs on your computer. It will automatically be updated when you install new codecs. This plug-in comes with a configuration file (“WicDecoder.ini”) which allows you to specify file extensions that should be ignored by this plug-in. Note: you have to restart Paint.NET after changing the configuration file of this plug-in. Some WIC codecs support file formats that can have multiple images in one file. This plugin will open all these images as layers (see the screenshot below). Download WicDecoder.zip Installation Unzip “WicDecoder.zip” Copy all the files into the FileTypes plugin folder (which is typically located at: C:\Program Files\paint.net\FileTypes) Copyright This software is available under MIT License. Source Code The source code of this plugin can be found at the following GitHub location: https://github.com/ReneSlijkhuis/paint.net-wic-plugin Note Some file extensions can also be covered by other plugins. In that case will the plugin that appears first in the file open dialog list be used. Remove conflicting plugins (temporary) from the FileTypes folder to test this one.
