Editing pixel alpha values

[Michael Crist]

I am hoping to find a way to edit alpha values in existing images imported into aseprite.  I would like to make an image on a layer fade in and out during animation, but I can't find a way in aseprite to either select a group of pixels and change their alpha values collectively, or to assign an opacity value to a layer, or to do anything but redraw the image in each frame with new pixels.  I can draw with any alpha I want - by changing the opacity of the pencil as I use it.  But once drawn, that's it.  Am I overlooking something?

Hi Michael,

You have a couple of options to do that:

1) You can change the "cel" opacity. Each frame/layer is a cel (or a timeline's cell), and it has an independent opacity level. You can adjust this level moving the mouse in the status bar or from "Frame > Cel Properties" menu.

2) You can use the "Edit > FX > Color Curve" and select only the alpha (A button) component. Then you can move the right curve point to the level of alpha you need.

Thank you sir!  I will try out both of those options.  I am having so much fun with this program!
