"This is mainly for the pixel artists. * u * When lining, how do you get smooth, nice lines and not uneven ones? I would hope you don't have to go pixel by pixel. ._. (I use PS, by the way.) Also, is there any way to correct your picture if you finish lining it and realize it's a little slanted? ; u ; /sob Thank you!"
I'll leave the qustion about pixels to someone more knowledgeable, but I can answer your second question o/
You're using Photoshop, yes? And a mac I see ~
I don't remember the equivelent for CTRL on a mac, but press that + T (or go to Edit > Free Transform) and that will allow you to tilt your img, as well as being able to resize and move it. <3
i'm sorry to say to get smooth lines
you have to go pixel by pixel
well not place the pixels one at a time
but once you draw the line you'll have to delete the jagged pixels
so your line is only one pixel thick
if you scroll down a little, i think it's the second step
theres just a comparison of a drawn and then cleaned line
like fish said if you want to correct a picture
you can use free transform, however you'll have to change some settings
since if you try it right now, you'll see that it goes kind of blurry
go to edit > preferences (it's close to the bottom) > general
and then you'll get a pop up
next to image interpolation there should be a drop down menu
click that and select 'nearest neighbour' and then click ok
you should be ready to rotate!
just note some of the pixels might not be moved perfectly after rotation
so you might have to go back and put them back in
also, if you change the brush blending mode (top kind of left theres a drop down menu) to clear
it'll act as an eraser but just remember to change it back
have you tried only rotating some parts instead of the whole thing?
pixel rotation isnt really something you can do well orz

mmm I'm not a super pixel artist god (like the lovelies under the pixels mentor category <3)
but I think I can help a bit (or kind of a tiny add-on maybe to caustic's amazing EVERYTHING). :3 For the uneven lines, it does depend slightly on the program you're using. But for the most part, I believe you'll need to strip away and the rigid edges manually. It may be difficult at first because you don't know which pixels to chip away and sometimes just removing one square makes a big difference, but after some practice, you'll definitely get the hang of it! When I started pixeling, I made use of the zoom function a lot.... like A LOT. Besides the undo button I mean. XD Or sometimes I would just push my chair back a bit to see if everything looked okay. Another thing I would say is BLINK A LOT. Pixeling involves so much eye strain like you wouldn't believe. @_@
Time for more than you ever wanted to know.
The trouble with rotating pixels is anti-aliasing. All images on a computer screen are composed of tiny colored squares called pixels. There are 72 'dots' per inch on most modern screen technology (with the exception of iPad's 'retina' display - high enough resolution, you can't see pixelation).
Thus, to make a diagonal line, we are really tinting two squares diagonal from each other. But if they are black on white - and tiny, our brain gets a kind of visual vibration ("aliasing"). After all, we see eery color in relation to those around it. So we blur the edges to make it less harsh by tinting those white pixels grey. This is most paint programs' (like Photoshop) default behavior.
However, when doing pixel art, we intend to preserve the look of the vibration. However, when rotating - PS attempts to keep the smoothed ("anti-aliasing") look it thinks we wants, so it calculates blurred edges. I'm not going to go into the math - but there is no real easy way for the machine to know which exact pixel you'd want to rotate where (anti-aliasing is needed to prevent heavy distortion). So you'd have to fix it up anyhow.
As a result, for fixing pixel art, it's best to fix as much as possible in sketch stage because their is less blending/aliasing leeway.
