Pencyl:

description: The former image editor for Stencyl. Used in Stencyl 3.4.0 and older versions. Some comment Pencyl sucks. However, this image editing software is good for quick edit for transparent buttons with opaque edges.  

advantages: easily make parts a sprite transparent within one image. For example, transparent buttons with opaque edges, A door with widows, A window, a container, 

If you still want to use Pencyl, here to download: 

 however, Stencyl 4.0 and later versions have issues running Pencyl.  but you can still use it as editor without using Stencyl. Alternatively, Pencyl can be downloaded and installed for Stencyl 3.4.0 or earlier versions.

The other issue with Pencyl is when switching between the eraser and the brush otherwise a decent editor for shading and complex background that Microsoft Paint cannot do. When switching these 2 tools, the opacity and radius tends to be bugged. 

You need to export as Native (.ie format) to save the project so that it can be continued later on. Using Save As will result the image or project in one layer. 

This image(layer 1) is first made with Microsoft Paint to produce a flat-coloured image because Pencyl does not have curved line tool. Pencyl is then used to create shading (layer 2)

Fill layer 2 with black then use eraser to erase to form desired shading. White spots are added to the excessive erase location to cover the error because Pencyl can only undo once.
