Centre of Image

Hi Guys,
Could anyone help me to get this starburst image exactly centred, it seems to have a small circle in the middle.
Many thanks
Stephen

Re: Centre of Image

View rulers, run horiz and vert guide lines at center of canvas, blow up image and center circle where guides cross. It's always going to look off center, because the points are off.

Re: Centre of Image

This should work for all versions of photoshop.
View > Rulers
Click Curser on left ruler and drag a guide to the center using the top ruler to find half.
Same with top ruler going down
Click magnify tool
Click zoom (looks like a magnifying glass)
Click and drag a small area around circle.
Select > All
Click Move tool (first one in tools window)
I think then you can nudge left/right/up/down with arrow keys
to center circle where the guides cross.
If you get a blank area on one or two sides, you can
probably bring the edges in a little with the Image > Canvas size window
and still keep it centered.

Re: Centre of Image

Unless you have every "spoke" as a separate layer, the best thing will be to recreate it.

I recommend you start off by making guides as suggested by others so you have the middle point (turn on the rulers, then click-drag from them to create guides). Then create a triangle shape, transform it into place as the top "spoke", then copy-paste the path and transform it to make the bottom spoke.

Now select both of them and copy-paste. Rotate them 90 degrees (hold down shift).
Select all four, copy-paste, rotate 45 degrees (hold down shift).


That's what I have done - and attached here as a PSD with layers.
I've also attached a PNG-file.

Ps: Illustrator is also an option here!

Thanks for your advice Chain, will have a go and let you know how it goes, when you say about Illustrator, do you think this is a better program for this sort of work.

Re: Centre of Image

Illustrator is superior for vector graphics.
If all you want is shapes like this starburst, then Illustrator is probably the way to go – but as seen in the PSD I gave you you can do some basic vector stuff in Photoshop as well (by using "shape layers").

Re: Centre of Image

Easiest way to find the centre of the image is to make a new guide
View > New Guide. Then just make one horizontal one and as an amount put 50%. Hit enter, make another one and set that to vertical and also at 50%. This puts it perfectly in the middle.

Good tip to type in the percentages. Don't know why I didn't think of that
