'advanced' erasing

[xhcsurge]

hi every1

ive been using paint.net for quite some time & it truly is the best program ever. Nevertheless I'm still missing this little thing

image a stupid picture like this:

but i want the sides of this blue thing to be perfectly straight

now if the background is white, i can easily draw a thick white line next to it, as an eraser, to the edges become nicely straight. however, with a transparant background, thats not possible, i need to use the eraser which gives me another crooked edge because of my un-steady hand. I could try a way around with layers & magical hands & stuff, but then my border isnt anti-aliased. So what i need is an eraser, and a line function, in 1, if u know what i mean. so i could make a line, which serves as an eraser.

damn this is hard 2 explain but i hope u understand what i mean.

is there some kind of plugin for this? or a small function that i have looked over?

thanks in advance

Are you tryin to make an image of a rotated rectangle, as that can be done by drawing a normal rectangle and rotating it with by right-clicking and dragging.

wow, thats cool & ye it solves the picture i made in the first post, tnx a lot

but what if i want, to fix this:

this windows logo has a transparent background, but as u can see, it isnt very nice cut

so id like to erase straight-edged with some kind of erasing tool

as im showing here with the pink line

to end up with straight, anti-aliased edges

isnt there a tool that lets me erase like that?

Alpha masking might help you out. CMD has a tutorial on his site... Hope this helps!

For you windows logo, add a new layer, move it to the bottom, fill color black.

Don't just fill color on the same layer as the logo.

Edit: Nevermind, the checkerboard is not really transparent..

Edit2:

In this win logo's case, you best bet is Color to alpha then feather
