[Unpaid] Image cleanup
Would someone be willing to fix up this image for me? It's very jagged. I did as much as I can with my skill level.

Or point me to a (very) simple tutorial?

Thanks.

But the image above isn't the original image, it's the result of a test attempt. Better start afresh with the original image... If the explanations pointed to above aren't enough, post the real image here (or a URL to it).

RE: [Unpaid] Image cleanup
How do I do this? I don't know how to grow it, or where color/color to alpha is.

Quote:- grow the selection by 2 pixels. The selection now includes the background, and the border pixels (anti-aliasing)
- use Color/Color to alpha with white (it will only applies to background and logo border)

Got a shot at your picture with paths. Here is the H redrawn with paths:

Stroked:

Filled:

Both:

(full XCF also attached, if this was enough to entice you using paths for the rest)

RE: [Unpaid] Image cleanup
Hello mate.

I did what you said, but it's still quite jagged.

Would you mind helping me, or telling me what to do?

Here's the original image. All I want is the word havoc, the rest can go away.

If I should use paths, how can I overlay my new image on top of this one, like you do with paper, so I can redraw it?

Thanks.

I just saw your reply.

That looks amazing!!

Can you tell me how to overlay so I can finish it? (Also, do you mind if I use what you have so far?)

So the image you posted was very far from the orjginal. Of course the original is quite jagged already...

I posted the XCF for your perusal.

Get acquainted with the path editor first: http://lightningismyname.blogspot.com/20...al_15.html

The XCF already contains a path for the H. Basically you take your original image and you draw the path over it. To get a nice outline, don't use too many anchor points, except in the sharp turns, and use the tangent handles as much as possible. Use my output as an example. I tried to stick to the original, including some wiggles, but you can decide to smooth them off.

I zoom in a lot (800%) when the curves are sharp, the straight lines are usually done at 200% zoom. The light gray layer is is used as a background for comfort (better contrast of the path).

Another example of a picture redone from the path:

RE: [Unpaid] Image cleanup
Yes mate, I have that site open from the other thread on how to use the path tool.

But what I'm missing is I don't know 'how' to place a drawing area on top of the image I already have, semi-transparent, so I can draw on top of it.

Like you do with paper: put the already made one right underneath it, you can see the outline. And then you take your pencil and copy it onto the top, blank piece of paper.

Thanks!

Layer/New layer (and specify "transparency" fill). But you don't need one to work with the Path tool. The path is virtual until you stroke it to the active layer. It is stored outside of layers. Open the XCF, above, and then go to Windows/Dockable dialogs/Paths. You'll find one called "H". Click its visibility icon...

RE: [Unpaid] Image cleanup
Hey mate.

Thanks for the help.

I'm lost on a couple things, though.

When I open the image you did and stroke path, nothing shows up? And I see above you have a black outline, but again: I don't see that black outline when I open the XCF file. What should I do?

Also, I pathed the "avoc." I could go in and make better paths to help it, but that's not what I'm stuck on:

How am I supposed to finish it? What I did was color the entire drawing area red, add the path stroke and then change the background etc. to white. However, you can see that left a red tint on the outside of the stroke, and .. I'd like it to be alpha.
But if I add the red 'after' stroking, the tint will remain alpha and not turn red, I assume?

1) I added the black outline after saving as XCF.
2) Maybe you don't see anything because the selected layer isn't the top one, so you are stroking "elsewhere". Or there is a selection active somewhere.

Your path is indeed a bit jaggy. Possibly you used too many anchors points and didn't use the tangent handles. I use 14 points for the outline of the "a" up to half the stroke between "a" and "v".

The proper way to render the path is:
1) Add a transparent layer
2) Path to selection
3) Bucket fill selection with red
4) If you want a white background, ad a layer below and fill with white.
5) if you want an outline, add a transparent layer on top and stroke the path.

By the way, you can merge paths ("H" and "avoc") so that in the end you have only one path to handle.

I attached a more "cleaned" version of the XCF that may make thing clearer.

RE: [Unpaid] Image cleanup
While lunch was cooking I did the "avoc" part of the path. I took the liberty to thin a little bit the long leg of the C. And come to think of it, the stroke between the O and the C is a bit thick, and could lose some at the top when it reaches the O. This will be left as an exercise Smile That's the good part with paths, you can edit the picture with ease and still get sharp results. Also added a little bit of drop shadow, because the look/effort ratio is maximal.

[attachment=720]

Full-scale XCF also attached.
