hi! i always feel, that the contours of skewed lines are too pixely (see attached screeny). does anyone know how to avoid that or keep that effect to a minimum? straight lines are fine, it's only the skewed ones. i'm using photoshop cs.

The simple answer is don't use Photoshop. Try Adobe Illustrator or Corel Draw. But there is a way to make Photoshop handle these lines a little better, unfortunately I don't use it, so perhaps ask Al Heeley. He should know. Until then search your Photoshop help files for the word "vector" or "raster" and you may find something.

i tried illustrator, but when importing the shape to ps it still seems to lose quality. also, there are tools in ps that draw vector graphics, but still quality is not quite perfect. maybe i'm just picky but i think, i have seen skewed lines on other peoples skins that looked much better. would working with a resolution of 2048x2048 help? or is corel draw the premium choice for clean nonpixelated shapes? is it superior to illustrator?

are you using photoshop with anti-aliasing ticked on in the little box at the top or off? Photoshop has a crude form of vector graphics, using the pen tool and new path, but its too complex for me to put a tutorial down. Have a look thru the resources section and fins a good tutorial on the web about using vectors in photoshop. And keep up the good work, you've been turning out some really nice skins on LFS files.

Try exporting or saving your Illustrator file as a PSD. Don't use any compression, at leat not until the end. When you open your new PSD in Photoshop it must be zoomed to 100% actual size or it looks very jagged. Photoshop is able to determine and display nice curves, but it can't create nice curves very well. Illustrator files saved as PSD should not lose their crispness, some small loss in quality may occur, but it should be negligible.

all right then, thanks for your advice. i'll keep those things in mind, when working on my next skin. just one more question: should the anti-aliasing-box be checked or not? (i'm not sure if it usually is.)

Hi, If your working with bitmap images (which you'll be ending up with anyway), a certain amount of aliasing is unavoidable. The only ways to really lessen the effects are resolution and contrast. This first being that at higher res the effect is less noticable, and the second being that with lower contrast between the curved/angular areas the effect is less noticable (low contrast of course isn't always that 'exciting' however. Another common way of lessening the effect is to work at a higher res than you finally want and scale the image down as your final step.
One rather annoying photoshop 'quirk' is that anti-aliasing on selection tools loop,magicwand etc is particularly cra.... uh ... rubbish on 'empty layers'. A trick I use is to work on a white layer when 'drawing' with selection tools, then delete the areas I don't want before filling with colour...

Hey chaps,
I had intended to post this very question so, hoping its ok, I will tag along.
I noted buntas comments about not using PS, now I use PSP and am comfortable with it but have started easing in to PS as I suspect it has more depth. In the meantime I have Corel PhotoPaint installed also but haven't really used it yet.
My question really boils down to this; Do I have the right software to go into bat against the dreaded jagglies or must I buy Corel Draw or Illustrator?
Any related advice or comments will be gratefully received, thanks, hooligun.;]
p.s. I have read all the posts in this thread, very interesting and useful stuff, thanks.

something you can check on..
1. Edit > Preferences > General. Under interpolation, set to Bilinear. Try that and see if it helps at all.
