The Inbox: Graphics-ct.419.mcz

A new version of Graphics was added to project The Inbox:
http://source.squeak.org/inbox/Graphics-ct.419.mcz

==================== Summary ====================

Name: Graphics-ct.419
Author: ct
Time: 20 September 2019, 7:45:53.388726 pm
UUID: 5deebfce-0321-9645-aebd-0b4bfb428259
Ancestors: Graphics-nice.417

Add Rectangle>>#pointAtFraction:

Example: [(5@5 rect: 10@20) pointAtFraction: 0.5@1] will give you 7.5 @ 20.

Be careful about using non Integers with Rectangles, too. As with Intervals, I think I remember that some of the API will break.

Re: The Inbox: Graphics-ct.419.mcz

Do you talk abound rounding effects? I remember some flickering effects myself when setting float bounds to the SystemWindowMorph, but I could not reproduce it; apparently, someone has added a check.

Also, Morphic is not the only client of Rectangles, is it? For example, LayoutFrames explicitly depend on floats.

Or what issue are you talking about else? :)

That may have been it.

Actually, I believe it is. Sure, other domains can and do use it but, IIRC, it has a distinct "screen" layout, where "topLeft" is 0,0 instead of bottom left as in Cartesia. Accidentally swapping the two points; (e.g., as in, bottomRightPoint corner: topLeftPoint) will also break things.

For example, LayoutFrames explicitly depend on floats.

Or what issue are you talking about else? :)

I don't recall, sorry.

Re: The Inbox: Graphics-ct.419.mcz

Hi Chris, hi all,

I'd like to bring this topic up again.
Personally, this tool has helped me in two projects until now. In
particular, I plan to use it for the reconstruction of Objectland.
Do you see any chance to merge this as is, or should we introduce a second
version #exactPointAtFraction: or something similar?

See also Graphics-ct.437
<http://forum.world.st/The-Inbox-Graphics-ct-437-mcz-td5120840.html> for
nearly the same discussion. I did not meet a use case where rounding is
important, but if you like so, we can implement two versions for this one,
too.

Best,
Christoph
