What are these lines

[behzad]

I get these faint white lines appear at the end of black lines

look closely
what are they?

Hi Quazy Wabbit,
I suspect they're because the lines aren't whole pixels in length, that's the usual cause, so you get an antialiasing effect.

Does it happen to yours?
It happens in illustrator too
on any width line

[Egg Bramhill]

As well as the shapes having to be in whole pixels, they must be positioned in whole pixels.

Here's a close up of the antialiasing within a bitmap. The 2 images are exactly the same apart from being mirrored and the all the internal shapes in the left hand side being offset to .5 pixels. Notice the additional in-between pixels on the left.

So if you want accuracy ensure you snap to grid of 1 pixel settings.

Here's the same image at 100%. You can hardly see the difference but it's still there.

Egg thanks but the white streak at the end of the line is my concern.

Egg thanks but the white streak at the end of the line is my concern.

Hasn't Egg already given you the answer - lines not occupying whole pixels?

[behzad]

I still see the ghost lines on the right of the lines only
this is at the end of the lines stretching out.

Maybe it is my monitor.
I bought it new HP W2007

Isn't language grand! The width of the line and the length of a line could be interchangeable terms. I think Egg is saying all measurements should be in whold pixels...both the width and height and the x/y coordinates.

It is my monitor, somehow these lines appear on the white background
must be LCD issue.
