'PNG Animations and Images' FileType Plugin (.PNG, .APNG)


Find the latest version of the plugin here: ImAPNG.FileType v1.4.zip [2022-01-07]

Thumbnail support for .apng file type: ImAPNG.Thumbnail v1.0.zip [2022-01-07]

ImXYZ.Thumbnail.dll Installer for ImAPNG.Thumbnail: See 'GIF Animations and Images' FileType Plugin



Loads and saves[not supported] PNG animations and images.  


Animated images contain a sequence of images called frames which a viewer application can show as an animation.


Because paint.net decides on the file extension which file loader will be used you have to change the extension of the PNG file to .apng.


On load the plugin loads all frames from the file and adds them as layers to a new Paint.NET document. Frame 1 will become the bottom layer and so on. Some information from the file (like frame durations or comments) will be stored in the layer names after the marker '//'.


[not supported]
On save the plugin will convert all layers to frames respecting the information found after the marker '//' in the layer names. The plugin does its best to reduce the size of the final file. The size depends on various settings.
