polygonal lasso tool

[laurensvvliet]

Hi everyone,

My problem is probably very easy to solve but i can't find a solution,

so the problem: I'm trying to make a triangular selection in a picture but when I'm using the polygonal tool,

the triangle doesn't have straight lines.

Hi Laurensvvliet,

Could you please try holding the Shift key while making the triangle using the polygonal lasso tool?

Regards,

Sahil

No that's not what I mean,

I mean when I close the selection it's a wobbly selection instead of a straight selection.

May I know which version of Photoshop are you using and Could you please post a screenshot of the issue here?

[laurensvvliet]

I'm using cc and I want the selection to have straight lines instead those shown above

The problem is you're viewing the image at 500%. In your screenshot, you can see the individual pixels, and selections are pixel-based. If you look at the selection in Quick Mask mode [press the Q key to toggle this], you can get a better idea of what the actual selection actually is. The marching ants are just the border between more or less than 50% selected.

Try viewing your image at 100%.

Yeah noticed that too, it's working better now thanks!

but I was zoomed in like that because otherwise I couldn't tell what was my picture and what my fill.

Here's a view at 1600%, with a selection saved as a channel, to show the relationship:

Thanks! you're my hero!

have a great day!

btw how do I snap my next selection to my older selection?

[laurensvvliet]

It's selecting the pixels I think but is it possible to ignore the pixels?

[Sahil.Chawla]

Try right clicking on the tool icon on the top and choose reset tool.

Let us know about the outcome.

[laurensvvliet]

No that doesn't do anything

[Sahil.Chawla]

Did you try updating Photoshop to CC 2017 version?

[laurensvvliet]

Going to try that!

[laurensvvliet]

Well I'm trying an other methode still thanks tho!
