Erase and paint in one stroke?

[genic]

Hi there, i wanted to ask if it Is possible to combine paint tools in one stroke?

 

In pixel painting i need a masked, randomized brush to first erase and then paint on the very same spot.

It would have to respect spacing, rotation, flip ect.

 

So that this stroke:

 

 

would become this:

Hmh, is this too simple or too difficult to comment?

I tried but cant find a way

Aww that is nice of you, thank you!

 

That would be a useful feature though wouldnt it?

Not to pile up bumps but replace the underlying with the new?

 

i bet this would be easily implemented too for the tools already exist, just need to be applied in order automatically.

May be... stack tools to one hotkey do the trick *

based upon your comments, you probably already know this, but with 2 steps
(first erase, then paint and extrude)
you can get pretty close to this capability with the 'paint with splines' tool:

 

 

and you get a better 'blend' between the extruded bits (I left 'additive painting' unchecked in depth options)

 

*edit* forgot to say, you'll need to have 'use spacing' checked in the options with the paint-with-splines tool...
I used 104% for the buttons alpha above.

Thank you guys very much for your solicitousness
i must apologize i do not speak english all that well, perhaps i did not explain it fully enough.

What i would need to happen is that erase and paint is applyed in that order at every spaced step of a brush stroke.
So that, if you have the spacing distance set like in my button example and you make a continuous stroke to place lets say 10 buttons in a row, the both tools (erase/paint) would be applied for every button in that order, successively.
You would start the stroke and once the spacing threshold is reached, the tool would ease the button mask and then paint it with the very same settings on the very same spot, then, as the stroke continues and the stroke reached the 2nd spacing threshhold it would again first erase the button, then paint it.
Erase, paint, ... erase, paint and so on, 10 times.
 
the button bump was not the best subject to demonstrate it either i am afraid.
what i would like to do with this is natural bumps of some kind.
Rather think of a pile of pebble rocks

How i imagine it is that you have a single rock brush-mask for bump/diffuse color.
Set random rotation, hue, spacing ect. and then just paint away.

Then, no matter how many rocks you painted on top of each other, every rock would be on top of the last one (or at least appear to be) and the very last rock you drew would always be on the very top of the stack for it would have deleted whatever bump/color that was under it before you placed that new rock.

Other things this would work well for are for instance foliage

or a pile of coins,

grass leafs or leafs of a hedge.
Just, anything you would like to pile but you do not want to intersect.

Okay, i just realized that whole "erase" thing may be confusing

 

In short, i need the paint brush to "replace" instead of "add" bump and color.
