How to make inverted round edges on a rectangle with an easy edge radius selection

[Mima]

Hi,

Hi,

Just wondering if anyone could assist with edge modes on corners of shapes? I’m trying to make tickets with inverted rounded edges and can’t seem to find an easy way to do this, apart from placing circles on each corner and minus them from shape. I have another app that gives you the option with shapes to select different edge modes, inverted round and straight and round and straight. This is then altered by an edge radius with a swipe!

I tried the edit option and moving the points took me to all places and not crisp round inverted edges.

Look forward on hearing if there is an easy way of making these edges.

Thank you

Hi Mima.

I think I'd do it the same way as you. (at least what I think you mean).
1. Create rectangle.
2. Create circle.
3. cut and paste circle onto rectangle layer.
4. Set Mode to subtract.
5. Copy the circle three more times.

You can do it with make editable, but I don't think it's as easy.
1. Create rectangle. (edit: it's faster (and more accurate) if you start with a rounded rectangle as you don't need steps 4 and 5.)
2. Right-click on rectangle and select Make Editable.
3. Double-click to edit.
4. Add a node either side of the corner where you want the curve to start/end.
5. Delete the corner node.
6. Select one of the nodes you just created and command-drag one of it's handles so that it has a 90 degree inward angle. (Command-dragging the handle will stop the two handles from being symmetrical)(pic below)
7. Repeat 6 for the other node.
8 Repeat 4 to 7 for each corner.

Finally, method 3, if you're happy with a bitmap:
1. Create rectangle.
2. Convert into Pixels
3. With the eraser tool and a hard round brush, dot each corner.

Hope this helps.

- Stef.

Hi st3f,

I really appreciate your fast and efficient response.

Yes, steps 1 to 5 is what I meant (incl picture) and thank you for going out of your way to assist with my query and advising that this is one of the methods you would choose also to complete the arc effect. Im glad I came to this thread as I was searching for days on tutorials, blogs etc etc on how to make an arc edge with a click of a button and just couldn’t find it. I just had to figure out!

Thank you
Have a good day!
Mima

No worries. Happy to help. Keep looking in from time to time as it's easily possible that someone has a better method. I usually get to a good answer but, some days, I have a blind spot a mile wide.

Matching inner corner radius for intersecting rectangular shapes

This is a method that incorporates rounding into the inner corner that is otherwise the 90⁰ square intersection corner. Illustrating another possible method to create rounded corners where Pixelmator shape work provides square intersection corners. This expands the 'round edge rectangle' topic to describe 90⁰ rounded intersection corners for multiple overlapping rounded corner rectangles. We construct a rounded inner corner to match the radii of the intersecting rectangular shapes' corners, where those rectangular shape corners are rounded.

Requirements:
1. Matching inner radius Stroke corner for intersecting rectangular Stroke filled shapes with 90° (right angle) outer corner radii (rounded corners).
2. Inner corner fill with matching corner radius.
3. Three new 'corner' shapes: Stroke circle (stroke with no fill, same pixel radius as intersecting rectangular shapes' corner, and same stroke width as intersecting rectangles' stroke) and Mask circle (same size as stroke circle, fill but no stroke), and Fill is a square rectangle shape (same width-height as Mask radius).

Method:
a. Assemble shapes: namely, circle Stroke, circle Mask, and rectangular square Fill;
b. Position over intersecting rectangles in bottom-to-top order, first Fill shape, then Stroke shape, then Mask shape and convert Stroke and Fill to pixels;
c. Quick selection tool select Mask, then hide Mask leaving circular selection active;
d. Focus the Fill shape and delete unwanted overlapping Fill shape pixels inside the active Mask selection;
e. Rectangular selection tool select and delete Stroke shape pixels so that only inner corner Stroke pixels remain.

This builds just one rounded rectangular shapes 90⁰ intersection corner. Many applications are possible for this method depending on how Stroke (inside/outside) and Fill (or lack of fill) are applied (inset/outset) to intersecting rectangular shapes and planes. This method could also be applied to Cross shapes and can be adapted in many applications for Pixelmator shape internal and external rounded corners. Note: not all corners (plane intersections) are square. This method would provide a stroke accented inset rounded corner for the rectangle corner discussed in this Pixelmator topic. We could use this method to create a ticket sheet for tickets with inset ticket corners, where simple circle shapes would be applied to "scalp" internal tickets on the Ticket Sheet. Pixelmator does not offer an easy way to create inset or “scalped” circular corners for shapes, for now.

... Photoshop has a paid plugin for circular scalping of square plane intersections between shapes, but just like Pixelmator, shape group performance suggests to experienced users that the use of back-tracking shape group copies is highly advisable. In that respect, Photoshop performance is mediocre at best while Pixelmator is EXCELLENT. Have fun ticketing, EVERYONE! ...
