If anyone knows how to use ibisPaint X, I may need some help

Just hit ok, or one of the illustration templates :3

elaborate.

We need more info on what problem in particular your facing on Ibis paint

W means canvas width
H is canvas height

Idfk the rest

Me who uses an app that has more limited tools and NO layers at all:

Folder is to select an image to start the drawing with from a folder, import picture is from your gallery. The W slider changes the width of the drawing, the H slider changes the height, and you can type them youraelf if you want. Everything below that is just some different sizes for the canvas that you can set. Nothing else is relevant unless you're a professional.

They are all just different options for the size of your image, choose a larger one for a higher quality image and a lower one for a pixelated image

You still need help?

No, I just press the ok button now
